Building News is an information portal for all professional building specifiers. Here you can find all of the latest construction news from around the UK and the rest of the world.

NHBC, the UK’s leading new homes warranty and insurance provider, has released its Technical Standards for 2024. The NHBC Standards define the technical requirements and performance standards for the design and construction of new homes registered with NHBC and provide guidance on how these can be achieved.

NHBC’s Standards are rigorously reviewed to drive incremental improvement and ensure that they continue to support builders and developers to deliver high-quality new homes.

 

Revisions to Standards for 2024

There have been several significant changes and updates across Parts 3 to 8. These include, but are not limited to:

  • a new chapter 4.6 – ‘Engineered fill’ in Part 4 covering NHBC guidance on meeting the Technical Requirements and recommendations for using engineered fill to support residential developments, external works and infrastructures
  • extensive revisions to chapter 6.1 including the provision of cavity trays to complicated junctions and additional insight on the design and specification of windposts
  • updates to chapter 6.3 regarding internal masonry walls and fire-stopping details
  • improvements to chapter 7.2 to provide more information on durability, ventilation strategies, integration of roof solar technologies and roof cassette systems
  • a revision of Part 8 (chapters 8.1 – 8.6) to improve the usability of the sections and improve guidance on heat pumps and solar photovoltaics, ensuring alignment with the Requirements for Electrical Installations (IET Wiring Regulations 18th Edition), and weep hole locations in relation to gas meter boxes.

 

Mark Russell, Standards & Policy Manager at NHBC commented,

“Our standards team is committed to continuous improvement and revising the Standards annually to ensure they remain current and relevant. I am proud to be part of such a robust process that continues to support the ongoing advancement of build quality and helps builders and developers to keep raising standards in house building.”

 

NHBC works continuously to review technical content, update the Standards and make sure they keep pace with the needs of the industry, the regulatory environment and, wherever possible, anticipate changing consumer expectations. It consults with stakeholders from across the industry to ensure the Standards are always relevant and provide the required support for builders and developers to keep raising the level of quality in house building.

 

This latest edition of the Standards will apply to every new home registered with NHBC where the foundations are begun on or after 1 January 2024.

KEY FINDINGS

 

Slowest decline in total activity for four months

 

Renewed rise in employment numbers

 

Suppliers’ delivery times improve again

 

 

December data indicated another solid fall in UK construction activity, although the rate of decline eased to the slowest since the current phase of decline began last September. A sustained slump in house building was the main factor holding back construction output, which survey respondents linked to elevated interest rates and subdued confidence among clients.

Improving supply conditions continued in December, with delivery times for construction items shortening for the tenth month in a row. Price discounting among suppliers contributed to a moderate fall in average cost burdens across the construction sector at the end of 2023.

At 46.8 in December,the headline S&PGlobal UK Construction Purchasing Managers’ Index™ (PMI®) – a seasonally adjusted index tracking changes in total industry activity – was below the neutral 50.0 mark for the fourth month running. However, the index was up from 45.5 in November and the highest for four months.

House building remained the weakest-performing category of construction work in December (index at 41.1), despite the rate of decline easing to its slowest since July 2023. Civil engineering activity (index at 47.0) also posted a softer pace of contraction at the end of last year.

Commercial construction meanwhile declined only modestly (index at 47.6), but the speed of the downturn accelerated to its fastest since January 2021. Some firms noted that concerns about the domestic economic outlook, alongside elevated borrowing costs, had led to greater caution among clients.

Total new work decreased at the slowest pace since the current period of decline began in August 2023. Subdued customer demand across the house building sector was often cited as a factor leading to reduced order books.

A softer decline in new work and hopes of a turnaround in demand conditions during 2024 contributed to a renewed rise in employment numbers in December. However, the rate of job creation was only marginal.

Mirroring the trend for construction output, latest data indicated the slowest fall in purchasing activity for four months. Where a decline in input buying was reported, this often reflected a lack of new work to replace completed projects.

Lower demand for construction products and materials resulted in shorter wait times for suppliers’ deliveries in December. Improving vendor performance has been recorded in each month since March 2023. Survey respondents often noted that competition for market share among suppliers had led to price discounting at the end of last year. Average cost burdens across the construction sector decreased for the third month running in December, albeit only modestly and at the slowest pace during this period.

Finally, latest data indicated somewhat upbeat business expectations at UK construction companies for output levels during the year ahead. Around 41% of the survey panel anticipate an increase in business activity over the course of 2024, while only 17% predict a decline. Anecdotal evidence suggested that subdued forecasts for the UK economy were a key concern, while hopes of reduced interest rates and a turnaround in market confidence were factors cited as likely to boost construction activity.

 


 

Fraser Johns, finance director at Beard, said:

“In what has become a consistent theme for the industry, weak performance in the house building sector continues to hold back construction output and weigh heavily on overall new work.

“A key driver has been elevated borrowing costs and general uncertainty in the economy, which is also being felt in the commercial space – contributing to a modest decline in the sector. It may be the case that clients don’t quite have the confidence just yet to commit to large-scale construction projects. Saying that, our view on the ground in the south remains positive with high demand – particularly from frameworks, and growing interest on the south coast as we prepare to open our latest regional office.

“There’s no question that resilience is key at the moment and the ability for firms to hold their nerve. While 2024 will undoubtedly present its fair share of challenges, we are beginning to see some positive indicators for the year ahead and expectations of falling interest rates. However, this does depend on the appetite of the Bank of England and the economy avoiding any substantial shocks. There’s an element of controlling what we can control right now and nurturing those close relationships with clients as confidence begins to return.”


Brian Berry, Chief Executive of the FMB commented:

“December’s Construction Output data once again shows a continued decline in house building rates, with commercial construction rates also down. There are, however, positive signs that the rate at which activity within the industry is declining is starting to slow, giving hope that 2024 may be a year when we finally start to see improvement. If the Government is serious about substantially boosting the UK’s house building rates and the wider construction industry, it must look at this as an opportunity to make real progress.”

Mr Monk’s approach in Cornwall is exactly what Mr Gove wants to see from local authorities

Cornwall Council’s portfolio holder for housing and planning, Olly Monk wants 10,000 homes built to battle Cornwalls acute housing shortage.  Monk says:

 “I don’t care if I am not re-elected, I just want to make sure there are homes for future generations here.”

Langarth Garden Village near Truro is an ambitious new town development – which is being built by Cornwall Council’s civil engineering arm, Cormac – is an attempt to address the area’s acute housing shortage while also building new infrastructure.

Data show that UK construction activity contracted for the third month in a row in December due to a slump in housebuilding. Meanwhile, there are over a million households on social housing waiting lists across England. And, in 2023, the number of homeless people sleeping in temporary accommodation hit an all-time high of 104,510 households, including 131,370 dependent children.

Cornwall has been particularly hard hit in recent years in part due to a rise in the number second holiday homes and holiday lets. This has led to a rise in homelessness and a crisis whereby low-income households – including key workers – increasingly can’t afford to live in the area.

Nestled between two hills, Langarth is exactly the sort of future-facing new town that both Leveling Up and Housing Secretary Michael Gove and Labour leader Sir Keir Starmer have been calling for as both of Labour and the Conservatives make bids to be the party of “builders, not blockers”.

Planning policy is something of a political oxymoron. It manages to be at once incredibly technical, humdrum, and, yet, controversial to the extent that it can trigger backbench rebellions in Westminster and social media wars between rival factions.

Those factions are known as the pro-building Yimbys – Yes In My Back Yard – and anti-development Nimbys – Not In My Back Yard. They can regularly be found warring on X (formerly known as Twitter) or leafleting at political conferences.

Langarth will be made up of approximately 3,550 new homes available only to local people. To make sure these homes can be supported, the development also includes a new 8km road, a cycle highway, two new schools, a rugby pitch, a football pitch and an environmentally friendly geothermal heating network.

But not everyone wanted Cornwall Council’s vital new housing initiative to get planning approval.

Across England, private rents are soaring above what people can afford, social housing waiting lists are ballooning and new homes are simply not being built quickly enough by private developers who are often accused of “land banking” – this is where they sit on land which is earmarked for development but wait for its value to appreciate before building on it.

Sometimes it is the builders who are, in fact, the blockers.

To make Langarth a reality, Mr Monk – who was first elected in 2017 – had to take on private developers who owned some of the land it is now being built on. He exercised his right to use Compulsory Purchase Orders (CPOs) to buy land they were sitting on but not building on back into public ownership. But, even then, landowners submitted planning objections citing a “conflict of interest”.

“I believe that councils shouldn’t be afraid to use [CPOs] when it’s for the greater good,”

“Everyone has their reasons for either supporting or objecting to development, but I don’t think councils should be afraid to push forward a scheme like this – we have to ensure that there is housing for local people.”

“We’ve got the resolve and determination to deliver houses,” he added. “If you just listened to every single objection, you’d never build a house anywhere.”

Mr Monk is, unusually for a politician, unbothered about being popular. He cares more, he says, about knowing he did his bit to shore up the future of Cornwall.

He advocates for local authorities being “strategic” and “thinking about what they need to be doing in the next 10, 20 or 30 years”. That, he said includes “making plans for garden villages and formulating a strategy to accumulate land and deliver”.

With no forward planning, Mr Monk says “balance in the housing will never materialise and things will just become more and more unfair”.

Mr Monk’s biggest fear is that housing will become “ever more out of reach” of “exactly the type of people you need living in communities” – that is key workers and young families; people on low and middle incomes.

In many ways, Mr Monk’s approach in Cornwall is exactly what Mr Gove wants to see from local authorities. While launching his long-awaited planning reform which will be delivered in a newly drafted National Planning Policy Framework, Mr Gove named and shamed 20 local authorities who are not delivering enough housing and seven who, he said, do not even have local plans.

However, the truth is that Mr Gove’s own plans to reform planning – which originally included forcing local councils to comply with mandatory housebuilding targets in a bid to get urgently homes needs under construction – had to be watered down at the end of 2022 due to a rebellion from 60 Conservative Nimby MPs who had concerns about building at scale in areas of natural beauty.

Mr Gove’s new plans now include investing in planning, but not bringing back housing targets.

Labour, on the other hand, is proposing to strengthen Section 106 – the mechanism through which developers are compelled to deliver social homes as part of new builds.

When Liz Truss decided to abandon the Conservatives’ “Stalinist” housebuilding target of 300,000 new homes a year in 2022, investors were spooked. Housing targets, like the local plans Mr Gove is demanding to see, show investors – on whom developers rely for funding – that housebuilding is being taken seriously and that there will be demand.

One of the councils that Mr Gove chose to criticise was the Labour-run Wandsworth Council in London. According to the Housing Secretary, Wandsworth is “exacerbating” housing shortages by putting pressure on developers to deliver affordable housing instead of allowing them to focus on getting new homes for private sale built.

Councillor Aydin Dikerdem, 32, is Wandsworth’s cabinet member for housing. He was elected in 2016.

Speaking at Battersea Arts Centre, he told said that

“local government needs more powers and more grants to ensure developers are delivering [affordable social housing], not further deregulation”.

In 2010, the Conservatives cut funding for affordable housing by 60 per cent as part of the austerity drive to cut the deficit between public funds and spending. Today there is an £11.5bn Affordable Homes Programme but it has not increased in line with inflation.

Mr Dikerdem has, like his Conservative counterpart in Cornwall, taken a hard line with developers in Wandsworth. He has overseen the redrawing of the area’s local plan (via something known as Regulation 18) and ensured that more truly affordable homes can be delivered via a new strategy called Homes for Wandsworth – which will see 1,000 council homes built on council-owned land.

Labour councillor Aydin Dikerdem, second left, has, like his Conservative counterpart in Cornwall Olly Monk, taken a hard line with developers in Wandsworth

Wandsworth currently has a social housing waiting list of nearly 10,000 households.

“We inherited a local plan from the previous Conservative administration we were unhappy with,” Mr Dikerdem said.

Historically in Wandsworth, property developers have only had to provide 35 per cent affordable homes when they built in the borough.

“We want an affordable housing/housing for private sale split which favours social rent at 70 per cent and intermediate products like shared ownership at 30 per cent,” Mr Dikerdem added. “That’s the maximum allowed under the Greater London Authority’s London plan and the most progressive a local council can be.”

And, instead of having local politicians be wined and dined by developers and their PR representatives, Mr Dikerdem invited them all to meet in Wandsworth’s town hall for “sandwiches and tap water”.

“The thing that developers want is stability,” Mr Dikerdem said. “They want to know where you stand and that you’re going to be consistent. So, it was really important for us to set very clear lines about what it is that we want.”

Mr Dikerdem says his team aim to deliver that stability because it will get homes built.

“Developers came to sandwiches and tap water,” he said. “It was an incredibly productive meeting. And they got excited about investing. The bar we’ve set here is not about speculative profit extraction, it’s about delivering the homes that people actually need.”

For Mr Dikerdem, it’s not just about building homes for private sale which can, and often are, snapped up by investors in London. It’s about building homes that are genuinely affordable for local people, which will bring down social housing waiting lists and get people out of emergency temporary accommodation.

“I think political leadership needs to be really tough on planning and to not be scared to push plans at the review stage,” Mr Dikerdem concluded. “The value of a newly built social home in London is worth fighting for. If you can get 10 more, 20 more, 30 more. It’s really worth it.”

Mr Dikerdem rejects Mr Gove’s implication that local governments like his who are trying to “negotiate essential social housing” with developers are the reason for low housebuilding figures.

Mr Monk is equally critical of the Conservative governments of the last 13 years.

“I don’t think local councils have enough power to build,” he said. “We want to build homes in Cornwall but trying to get that through planning is [too difficult].”

Mr Monk cites the example of giving telecommunications companies permitted development rights to put up 5G masts –

“if they did something like that for housing, you’d see a much bigger increase [in the volume] of affordable housing rolled out across the country”.

“I am disappointed with all governments, not just the current Government. They have failed to make really meaningful changes to the planning rules to allow the delivery of homes because of this protectionist attitude that people have.”

The Department for Levelling Up, Housing and Communities spokesperson said: “As the Housing Secretary has recently made clear, we must build more homes, but they need to be in the right places where people want to live. We recently laid out an ambitious long-term plan for housing and are on track to deliver one million homes this Parliament.

“We are clear that the way to deliver housing is through up-to-date local plans. The new National Planning Policy Framework increases the incentives for authorities to get local plans in place. There is now no excuse for any local authority not to have a plan in place, leaving communities without the homes they need.”

A specialist carpenter, who works across much of the Cotswolds carrying out new-build and refurbishment work, has been making use of CaberFloor P5 and other panel products from the West Fraser range throughout his career.

Paul Doherty, who trades as Doherty Carpentry, is in big demand from Moreton-in-the-Marsh across to Stratford-upon-Avon – while also serving customers as far away as Coventry and working for bigger building contractors as well as individual property owners.  Meanwhile, for many areas of his work, Paul chooses to purchase West Fraser products such as SterlingOSB Zero, CaberDek and CaberFloor P5 because of their broad performance benefits and competitive pricing.

Paul Doherty comments:

“I get asked to undertake a lot of different types of contracts, from barn conversions and restoring old cottages, to working on new-build properties and erecting garden rooms for customers.  In fact, I created an outdoor kitchen this summer for one client, though the work I did on an old stone-built property at Blockley – near Chipping Camden – pitching a new cut roof and creating new bedroom spaces, is more typical.

“The floors there were made up of 8 x 2 solid timbers, though I also install CaberFloor across metal web and other engineered timber joists.  As long as you’ve got a good structure, and you get your first line of boards in straight, they run true, interlock well and provide a solid, squeak-free floor.  Part of that is that I normally apply the CaberFix adhesive in the joints as well as across the top of the joists as we screw them in place.  I’ve been using the West Fraser range for over 20 years now and have always been impressed with the accuracy, wide availability, and the competitive pricing.”

CaberFloor P5 is one of the UK’s most widely specified particleboard products, conforming to BS EN 312: part 5 and carrying BBA Agrement certification. The 2440 x 600mm panels are available in thicknesses of 18 and 22 mm with tongue and groove edges along all four sides.  They offer excellent stability as well as moisture resistance and deliver a sound reduction performance of 44 dB.

All West Fraser panel products produced in the UK are net carbon negative and manufactured in mills that have obtained the coveted environmental ISO 14001 accreditation.  Responsibly sourced, the panels are FSC certified and created from locally grown timber, cutting embodied carbon from transportation.

Neil Kirwin, Southern Specification Manager at SFS, discusses why engaging with building product manufactures

can help with planning ahead to overcome potential supply chain challenges

that could threaten specifications in the building industry.

Engaging with building product system and manufacturers can deliver an essential level of support to specifiers. That includes planning ahead to overcome potential supply chain challenges that could threaten whether the desired system even makes it onto the building.

If a solution is specified, then that means it contributes to a project’s goals – be those goals around thermal performance, fire safety, sustainability or corrosion.

A robust specification is one where all parties understand the value that a particular solution brings to the project. If it is too easy to substitute the preferred solution with a different one, then the specification was not robust, and it is more likely that performance gaps will occur in the finished building.

 

Defining market engagement

This is to describe research and dialogue with potential suppliers before a contract notice for a specific procurement requirements or project is published – or before a procurement is otherwise formally commences.

 

Tips to overcome supply chain challenges

All SFS technical papers and blog posts around robust specification and engagement with technical expertise advocate engaging as early in the project as possible.

It can often feel like the only time to engage with manufacturers is during a live project. But that is when timescales are most compressed. Everything is needed urgently at almost every stage. Stage 4 of the RIBA Plan of work is a particular bottleneck. Typically, the technical design only starts at this point. The people who were involved in the earlier stages are unlikely to have done preliminary technical design, and don’t go on to participate in the subsequent detailing.

As a result, it leaves little room for engagement with expertise that would be really helpful. If a manufacturer is consulted at all at this point, it might be too late for them to offer a solution that the project would benefit form. In the current market conditions in the construction industry, the supply chain challenges we’ve all become so familiar with make it unrealistic to expect that manufacturers and suppliers will have excess stock to fulfil unexpected orders. Undertaking some technical design at an earlier stage of the project timeline can help with planning, especially on large projects. Some designers and specifiers prefer to maintain an open specification, but shortages of raw materials and stock are affecting all supply chains.

When global demand for the construction sector continues to increase, there is no reason to expect that to change.

 

What does engagement outside live projects live projects look like?

What if the best time to speak to expert product manufacturers is not during a project at all?

Another option for engagement is outside the project’s environment. This is a different form of engagement which is more about having an open dialogue about what support is typically required on projects. It gives the specifier an opportunity to learn more about the capabilities and values of the manufacturer in terms of being able to provide that support. Shared values are an important part of getting the most from collaboration. Integrity and openness can lead to success in any of the performance areas we are covering in our robust specification content.

When there is no live project to discuss, then it is obviously difficult to work towards specific solutions. But a mutual understanding of how a better working arrangement can be achieved can lead to improved collaboration when another project does start.

Eurocell fabricator, Rapid PVCu has secured the first triple glazed site for Taylor Wimpey in Sunderland.

National housebuilder Taylor Wimpey will use Eurocell’s Modus windows system at its Herrington View residential scheme in Penshaw, Sunderland.

Doncaster-based Rapid PVCu is a new-build specialist and has worked with Eurocell, the UK’s leading manufacturer, distributor, and recycler of PVC-U building products for 14 years.

Eurocell’s market-leading Future Homes Ready Modus window system is made from 50% average post-consumer recycled PVC-U and is manufactured using innovative dual material extrusion technology (DMET). The ultimate sustainable option, with a significantly lower carbon footprint than profiles made or recycled outside the UK.

For the new homeowners that will move into the neighbourhood, with U-values as low as 0.86, the triple glazed windows will reduce carbon emissions, use less energy to heat and present higher levels of security.

Eurocell has been working closely with national housebuilders to enable them to achieve energy efficiency and carbon reduction targets that meet the Future Homes Standard.

 

Martin Benn, Head of New Build at Eurocell comments:

“Working collaboratively with housebuilders is something we really value at Eurocell, and this project is another example of the demand for our market-leading Future Homes Ready Modus system that ensures housebuilders meet the requirements that will be introduced in two years’ time. We look forward to the scheme completing and for future projects with Taylor Wimpey.”

 

John Duggan at Rapid PVCu adds:

“This has been a fantastic project to work on collaborating with both the Eurocell and Taylor Wimpey teams to provide innovative, triple glazing windows which are the highest quality of their kind. Triple glazing really is the best option for lowering energy consumption and the fact that the Modus window system is made with recycled PVC-U makes them incredibly attractive for housebuilders. The windows will look really smart once the homes are finished and will provide longevity and energy efficiency for the new owners.”

The Public Sector Decarbonisation Scheme has now launched, which will support the aim of reducing emissions from public sector buildings by 75% by 2037. It will provide over 1.5 billion of grant funding up until 2026 to support public sector organisations which are facing pressure to deliver carbon savings and meet upcoming Net Zero targets.

Eighty percent of UK buildings that will exist in 2050 have already been built, and while it might seem easier to develop new buildings which meet sustainability targets, the opportunity to retrofit existing building stock to ensure they meet climate change targets can’t be ignored.

With the built environment sector accounting for 40% of all carbon emissions released, there is a growing awareness around whole life carbon and ensuring that we are using less carbon for the whole lifecycle of a building.

In support of our public sector partners, SCF has set up the SCF Climate & Sustainability Working Group, a collection of contractor representatives with expertise in carbon reduction and sustainability.  It is their job to monitor developments in legislation and best practice and in this article, we have taken their insight to support you to make informed decisions about retrofit.

With many universities and schools pledging to become carbon zero by 2030 or 2050, is the greenest building always the one that already exists and what challenges do educational establishments face when considering carbon retrofit?

 
To build or not to rebuild? The issue of historic buildings

Universities and schools are some of the most historic buildings in the UK so retrofitting them presents a complex challenge. According to Historic England, older buildings require a special approach as they take up moisture from their surroundings and release them according to environmental conditions, heating up and cooling down more slowly. This equilibrium can be affected when changes are made to increase energy efficiency and can have adverse consequences such as moisture accumulation or overheating.

Each historic building is unique, and despite the potential carbon cost, it might not be appropriate to retrofit due to structural or design issues – in which case a rebuild may be the better option.

By ensuring due diligence is done and processes such as a two-stage open book is undertaken via frameworks such as SCF, this will enable building risks to be assessed early on, allowing the entire ecosystem to be considered.

If suitable however, retrofit can make a huge difference to carbon reduction. A heat pump can reduce carbon emissions by up to 70% compared with a gas boiler and The UK Committee on Climate Change has highlighted  the need to speed up their deployment. But proper insulation needs to be in place or viable as an option for this efficiency to be maintained, so it’s important that this is assessed on a case-by-case basis.

Safety considerations must also be considered. Retrofitting can serve to address the need for repairs faced by some schools and universities across the country, including asbestos removal. But it might be the case that the entire building is unfit for use due to structural safety issues, in which case a rebuild will need to be undertaken.

 

Are your buildings retro(fit) for the future?

Retrofitting existing buildings presents an educational opportunity to pupils, creating a dialogue about sustainability between students, local authorities, and teachers. With a skills shortage in retrofit, schools, colleges, and higher education institutions have a part to play in inspiring future generations to consider the importance of sustainable buildings.

Biodiversity is also a key factor to consider. With the biodiversity net gain rules coming into effect in November 2023, it’s worth thinking about retrofit as an option as this will ease the biodiversity commitments due to the lessened impact on site.

Another key consideration is whether existing educational buildings are sufficient to meet the needs of the future student population. According to a report by the Office for Students, UK’s higher education population is expected to grow by 12.3% by 2025, increasing the requirement for additional campus buildings. Contractors can therefore work closely with universities to ensure they are meeting sustainability targets in future buildings when retrofit simply doesn’t meet future spatial requirements.

Recently, SCF contractor Galliford Try built a new state-of-the-art tech park at Chichester University to provide new engineering and digital creative technology facilities to support 500 new undergraduate and postgraduate student places per year. Passivhaus design principals were applied resulting in running costs efficiencies.

 

What are the cost considerations?

Retrofitting is not a quick fix to rising energy bills, but in the long run modifications to a heating system will improve a building’s lifetime running costs while reducing energy consumption. The House of Commons Library estimates that schools’ energy bills have risen by 93% in the last year, so retrofitting can enable schools and universities to make much needed savings.

 However new buildings may reduce the need for future repairs, while also reducing carbon to the extent that the original embodied carbon emitted during the build process will be offset.

 

One size doesn’t fit all

The issue of whether educational institutions should take a retrofit first approach is complex. Each has its own goals and barriers. However, with the National Audit Office estimating that 60% of current educational building stock was constructed before 1976 when sustainability concerns were not as much of a priority, it’s important that this imbalance in addressed.

Whether or not to retrofit, shouldn’t be a binary decision, or one which is made in isolation. The environment is a huge issue for students today and will continue to increase in importance as the impact of climate change accelerates. It’s important that solutions are chosen that will do the best by planet and people.

Labour leader Sir Keir Starmer recently labelled the King’s Speech, which did not include any proposals for planning reform, a “missed opportunity” to provide affordable housing in England.

If it wins the next election, Labour has promised a “blitz of planning reform to quickly boost housebuilding”, with a pledge to build 1.5 million homes over the course of the next parliament. But what new measures might the party’s planning reform “blitz” contain? There are a number of changes that could be relatively quick to enact and would help to speed up England’s planning process.

Set mandatory housebuilding targets across England

The 2023 Levelling-up and Regeneration Act (LURA) contains provisions that would allow the secretary of state to make national development management policies (NDMPs) “in relation to the development or use of land in England, or any part of England”. Section 93 of LURA amends the 2004 Planning and Compulsory Purchase Act so that, in the event of a conflict between the statutory development plan for an area and a NDMP, the conflict must be resolved in favour of the NDMP. An incoming Labour government could therefore use this power to set mandatory housing delivery targets for all areas of England.

Make housing a Nationally Significant Infrastructure Project

The 2008 Planning Act introduced the concept of nationally significant infrastructure projects (NSIPs) and revolutionised the consenting process for such projects by providing a ‘sped up one stop shop’ for obtaining development consent orders (DCOs). Promoters of DCOs under the Planning Act regime know that their application must be determined within statutory timescales and that the DCO can cover a range of consents and powers needed to deliver a project, including powers for the compulsory acquisition of land. Housing could be added to the list of NSIP projects in Section 14 of the Planning Act so that housing developers can benefit from this expedited consenting regime to promote housing schemes of scale.

Reform the process for varying planning applications

Currently, if a developer wishes to make any variation to its planning permission it is subject to archaic processes that limit the extent of the variations. Section 73 of the 1990 Town and Country Planning Act (TCPA), which is the power enabling changes or removal of conditions on a planning permission, does not allow amendments to be made to the description of development, otherwise known as the ‘operative part’, of a planning permission. The process is burdensome and bureaucratic.

Notwithstanding new Section 73B of the TCPA that is proposed under LURA that seeks to deal with some of these restrictions, the whole process of making changes to a planning permission could be massively simplified so that an applicant can apply to make changes to an existing planning permission to any extent and without that process resulting in the grant of a new permission. Such applications could be determined in the same manner as a ‘normal’ planning application is currently, such as having regard to the development plan and any relevant material considerations.

Mandatory green belt review in ‘local plan’ process

England’s National Planning Policy Framework (NPPF) currently states that green belt boundaries should only be altered in “exceptional circumstances”. This could be changed to state that green belt boundaries must be reviewed as part of the local planning process. Such reviews could be undertaken in accordance with nationally prescribed criteria and standards and areas that perform poorly, when tested against the ‘five purposes’, should be released for development in cases where this is considered a sustainable option for the area.

Any loss of green belt could be mitigated by providing for designation of an area of equivalent size as ‘biodiversity net gain land’. This would maintain protected areas of open space and simultaneously provide for the creation of BNG credits that could be sold to developers who need an offsite BNG solution.

Abandon the infrastructure levy and reform CIL

The new infrastructure levy proposed under LURA could be abandoned and the current Community Infrastructure Levy (CIL) regime reformed and simplified. The proposals set out in the 2016 CIL Review Group report (64 pages / 3.22MB PDF) should be enacted, and CIL should be replaced by a hybrid system of a low level ‘local infrastructure tariff’ and planning obligations contains in section 106 of the TCPA.

Encourage section 106 negotiations to start at application submission

Section 106 agreement negotiations are frequently cited as a significant delay to the path to securing planning permission. It is commonly the case that negotiations do not start until the developer has received resolution to grant from the local planning authority (LPA). The national planning practice guidance should be amended to state that the LPA should engage in section 106 negotiations at any time from submission of the planning application if the applicant so wishes. Twin tracking the determination and section 106 negotiation periods should significantly reduce ‘back end’ delay in the planning process.

Update model form conditions

Existing planning practice guidance currently contains a link to the old Circular 11/95 (use of conditions in planning permission), which is now nearly 30 years old. This should be updated, and new much-promised model conditions should be issued that should follow a logical ‘development cycle’ structure – from pre-commencement conditions to pre-occupation conditions, and finally to conditions requiring on-going compliance. This would provide more certainty for LPAs and developers and avoid poorly drafted conditions which give rise to legal challenges and issues further down the line.

Reform Section 106 of the TCPA

Section 106 of the TCPA should be reformed so that the four powers listed in section 106(1)(a)-(d) are removed. Instead, it should be stated that a section 106 agreement can secure any type of contribution and/or require any form of action to be taken/performed provided that the tests set out in Regulation 122(2) of the 2010 Community Infrastructure Levy Regulations are met. It may also be beneficial for these tests to be revisited and liberalised to provide more flexibility to developers and local planning authorities when they are looking to secure mitigation or planning gain.

Allow local planning authorities to ‘contract with themselves’

Local authorities are some of the largest landowners in the country and are often looking to promote their own land for development, particularly in order to secure higher than normal levels of affordable housing. When a local authority is acting as both landowner and local planning authority problems arise in the structuring of the section 106 agreement due to the issue of ‘contracting with yourself’.

This issue is resolvable but only by putting in place relatively complex legal structures. This could be made much simpler if legislation were introduced, perhaps by amending section 106 of the TCPA, to make it clear that a local authority can contract with itself to secure planning obligations. The secretary of state could be specified to be the enforcing authority for such time as the land is vested in the local authority.

Introduce model form development management policies

Very often, large parts of a local plan are ‘boilerplate’ development management policies that don’t much differ from LPA to LPA. The government could produce a set of model form development management policies that can then be adopted by each LPA, with or without modification, as they wish and thereby cut down on the length, and process associated with the making, of the local plan.

Leviat is delighted to launch their new Industry Insights series, which critically examines a range of topics and issues facing the Construction Industry, and aims to provide clear, informative and educational content to support the growth and development of the sector. Featuring a whitepaper and in-depth video interviews with thought leaders from across the industry, the series brings clarity to the evolving regulatory landscape and the necessary drivers for change.

 

The Industry Insights video series begins with the perspective from three leading industry bodies on the regulatory landscape and how they drive change. Filmed at Futurebuild 2023, Dr. Gavin Dunn, Chief Executive of the Chartered Association of Building Engineers (CABE) discusses the key role he has played in the development of the Future Homes Standard and whether the industry is ready to meet the 2025 targets. He also provides insight into the performance gap and responds to the question about whether a joined up approach to Building Regulations Part F, L, O and S (FLOS) will address issues and close the gap.

An interview with Eve Livett, Chief Executive Officer of the Association of Brickwork Contractors, discusses the significance of recent changes in the industry, such as Brexit and more stringent building regulations, as well as the demand for brick in new buildings and homes. She also talks about the impact of the Future Homes Standard and Building Safety Bill and why the energy efficiency standards we set now are important to keep us on track with our sustainability goals.

Expanding the Industry Insights series, Leviat has also interviewed its staff members to gain perspectives on the broader issues facing the sector. These spotlights focus on sustainability, company culture and the future of construction. By featuring the diverse voices of its workforce, Leviat adds another dimension to the series.

To gain further insight into the importance of regulatory compliance, Leviat’s new whitepaper ‘Bringing Clarity To Regulatory Changes’ looks at the current regulatory landscape and what new legislation means for structural components and the responsibilities of those that use them. It provides insight into the forthcoming changes and ensures stakeholders are ready to meet obligations and avoid risks going forward. As part of the series, Leviat will continue to publish bite-sized whitepapers aimed at supporting the industry.

Commenting on the ‘Industry Insight’ series, Alastair Bell, Commercial Director at Leviat said:

“We are delighted to offer the construction industry the ability to expand their knowledge through these in-depth interviews and whitepapers. For professionals wanting to know more, and stay up to date, the Industry Insights series will shine a spotlight on the built environment’s most pressing issues.”.

The campaign will provide weekly content releases via the ‘Leviat in the UK & Ireland’ LinkedIn channel.
