Britain continues to break clean power records
Households across the UK continue to embrace solar power as the government accelerates its clean power mission.
- 269,000 solar installations completed in 2025 鈥� the highest total ever recorded in a calendar year听and听37% larger than the year before
- 23,000 new solar installations in April 2026, with more than half installed on听homes听鈥� showing households听are turning to homegrown energy following the war in Iran
- 9 of the 10 strongest months for solar deployment听on record听have happened within the last year
Households across the UK听continue to embrace听solar power as the government accelerates its clean power mission to reduce听Britain鈥檚听exposure to volatile fossil fuel markets following the听outbreak of the听war in Iran.听
New government data published today shows that 2025 was the strongest year on record for solar deployment, with 269,000 installations completed across the UK. Around 255,000 of these were rooftop solar - meaning at least 95% of all new solar was installed on homes, businesses and other buildings. This equates to a new rooftop solar installation every 2 minutes throughout 2025.
April 2026 figures published today also confirm that 9 of the 10 best-performing months ever recorded have occurred in the past year, with nearly 23,000 new installations in the last month alone - and more than 1 in听2听of those being rooftop solar听on homes, showing households are increasingly choosing to generate their own power.听
The milestone follows the UK surpassing 2 million total solar installations for the first time in March 2026, across homes, communities and solar farms nationwide. It also comes as new annual figures from the government today show that the cost of acquiring and installing solar PV has decreased by up to 9%.
The surge reflects growing government investment in solar power to deliver clean energy and help lower bills, with rooftop solar saving families up to 拢480听a month.听This includes:
- consenting听Springwell Solar Farm, the largest power-producing solar farm in UK history
- driving forward with the rollout of 鈥榩lug-in鈥� solar panels (low-cost panels that families can put on their balconies or outdoor space) to be available in听shops within months and save people money on their bills
- ensuring solar panels are fitted on new homes听in England听as standard
Energy Secretary Ed Miliband said:
As听we听face a second fossil fuel crisis in 5 years,听Britain is taking听back control of their energy by听generating more clean power than ever听before.听Record-breaking solar growth means greater energy security, lower exposure to volatile fossil fuel markets which we听can鈥檛听control.听
This is what our clean power mission looks like: backing homegrown energy, giving people more control over听their bills, and building a stronger, more resilient energy system for the future.
Businesses and public services are also embracing Britain鈥檚 solar revolution - cutting costs and strengthening energy security.听
Numatic听International, the maker of Henry the Hoover, has launched a new solar park expected to supply around 20% of its听Somerset听factory鈥檚 electricity demand.听听
Mid Cheshire Hospitals NHS Foundation Trust has installed rooftop solar expected to cut bills by around 拢9,500 a year, while Wren Kitchens is building what is set to become the UK鈥檚 largest factory rooftop solar array.听
These installations build on the success of Great British Energy鈥檚 solar scheme, with a further 100 schools and colleges set to receive rooftop solar this year.
