In a major boost to the UK’s net zero goals, the government confirmed that nearly all new homes in England will be built with solar panels by 2027. Under the new policy, housebuilders will be legally required to install rooftop solar as standard during construction, aligning the country’s housing strategy with its climate ambitions.
The move comes as Labour leader and Prime Minister Keir Starmer doubled down on his government’s climate agenda, brushing off recent criticism from former Prime Minister Tony Blair. Starmer has made it clear that addressing the climate crisis is “in the DNA of my government,” setting ambitious targets like decarbonizing the electricity grid by 2030 and building 1.5 million homes before the end of the current parliament.
The cost of building, the benefit of saving
The solar panel mandate is expected to add between £3,000 and £4,000 (approximately $3,750 to $5,000) to the construction cost of each new home. But experts estimate that homeowners could save over £1,000 (around $1,250) annually on energy bills. Labour also projects that their broader energy strategy will cut household energy bills by £300 a year.
While the upfront investment might raise eyebrows among developers, the long-term savings for residents and environmental benefits are harder to ignore. As Lily-Rose Ellis, climate campaigner at Greenpeace UK, put it: “For too long we’ve wasted the free energy that falls on the roofs of houses every single day.” She called the new policy a “common-sense decision” that ensures families will benefit from reduced bills while contributing to clean energy goals.
Not just new builds: retrofitting support on the way
Ministers are also drafting plans to support solar panel installation on existing homes, using a mix of government-funded loans and grants. While the details are still being finalized, the message is clear: solar isn’t just for the newly housed. The government aims to make solar a staple of UK rooftops, old and new alike.
A government spokesperson reinforced this commitment, stating: “We have always been clear that we want solar panels on as many new homes as possible because they are a vital technology to help cut bills for families, boost our national energy security and help deliver net zero.”
Political solar flares: Blair and backlash
The announcement follows a lively political back-and-forth sparked by Tony Blair, who recently described current net zero policies as “irrational” and “doomed to fail.” Blair argued that asking the public to make lifestyle sacrifices would have “minimal” impact on global emissions and warned against phasing out fossil fuels too quickly.
His comments, made just days before local elections, ruffled feathers at No. 10. In fact, officials reportedly contacted the Tony Blair Institute for Global Change (TBI) directly, prompting a statement clarifying that the institute supported the government’s climate policy.
Critics were quick to read Blair’s remarks as a jab at Starmer’s agenda. But Starmer has held firm. As a signal of this resolve, his government is pushing forward on solar panel legislation and reaffirming its broader energy goals.
Unions weigh in: support with caveats
While the policy has garnered applause from environmental advocates, some union voices are urging a more nuanced approach. Unite, the UK’s second-largest union, echoed concerns raised by Blair. General Secretary Sharon Graham stressed the need for a just transition that protects workers. “Workers want net zero,” she told Times Radio. “The problem that we’ve got is that there is no investment currently about how we get to that and also secure jobs.”
Citing the shutdown of crude oil processing at the Grangemouth refinery, Graham noted a lack of job investment in sectors like wind manufacturing and sustainable aviation fuel. “You cannot just plough on regardless and throw all of these workers on the scrapheap,” she said.
The bottom line
Despite the political squabbles, the future of solar power in the UK looks bright. With solar panels set to become a fixture of new homes, and plans underway to support retrofitting for existing ones, the government is signalling that net zero isn’t just an abstract goal—it’s a rooftop reality in the making.
As the UK navigates the balance between climate ambition and economic pragmatism, one thing is clear: sunshine, long overlooked, is finally being put to work.
