UK Government should extend support for solar PV for new-build homes to businesses as well, says Longevity Power
Renewable energy consultancy welcomes Westminster’s plan for rooftop solar on all new houses by 2027 but also calls for action to drive solar uptake on commercial buildings
The Government’s newly announced plans to expand residential solar on new-build housing in England are a welcome step but measures are also needed to encourage businesses and commercial landlords to invest in and install rooftop solar systems on commercial buildings, according to Longevity Power, the strategic renewable energy consultancy.
Commenting on the news, Anthony Maguire, Longevity Power’s Managing Director, said,
“The Government can accelerate the UK’s rooftop solar revolution by assisting businesses and landlords with installing solar PV and batteries on commercial buildings – not only offices and warehouses but also shopping centres, transport hubs like railway stations and airports, and car parks.
“The UK can follow the example of the French and German governments with legislation that provides companies and building owners with a guaranteed strike price for selling any unused solar power back to energy providers – but in a way that avoids needing to pay compensation during times of negative pricing due to solar over-production.”
Maguire explained, “There’s huge untapped potential here in the UK to do more with commercial and industrial solar PV. For example, among the 30 largest shopping centres in the UK, just eight currently have solar installed. And of the 334 shopping centres and retail parks nationwide that Longevity Power has analysed only 48 have solar PV installed – that’s less than 15 percent.
“Installing rooftop solar on offices and industrial buildings is proven to cut energy bills for tenants and landlords and can make an important contribution to the UK’s wider effort to reduce emissions, achieve net zero, and boost the country’s energy independence and security.”
Maguire’s words also follow the announcement in March by the Government’s new state-owned energy firm GB Energy to allocate £180 million in funding for solar panels for schools and hospitals. Local health trusts and education bodies across the country have already received grants to install solar panels.
Maguire said,
“The Government’s funding via GB Energy for solar for the public sector shows its commitment to long-term energy resilience and sustainability for the UK. Businesses and landlords can feel more confident in opting for renewables themselves.”
“Schools and hospitals in particular are highly visible public buildings at the heart of communities, so the impact – both in reducing emissions and increasing public awareness of renewables – will be significant.”
Maguire explained that the initial capital investment needed has historically been a barrier to rollout, especially for publicly funded institutions with tight budgets.
However, Maguire also warned that the Government must address the problems regarding the UK’s energy grid constraints if it wants to achieve its goal for the UK to become a clean energy superpower.
He continued, “Many clean energy projects – especially those over 1MW – are currently delayed or in limbo due to grid connection limitations, including public and private buildings with large roof space.
“GB Energy needs to determine early in the grant application process whether projects are designed for on-site consumption or are being built to export energy to the grid. That way, projects that have minimal grid impact – such as the ones we’re expecting for schools and hospitals – can get underway quickly and start benefiting sooner.”
Maguire concluded by saying, “Alongside rooftop solar, we need to see a strong commitment to battery storage. Batteries don’t just store excess solar – they help manage local energy flow, ease pressure on the grid, and create flexibility in when and how power is used.”
