The Government has said Britain recorded its strongest year for solar deployment in 2025, with 269,000 installations completed across the UK. The Department for Energy Security and Net Zero said around 255,000 of those installations were rooftop solar, meaning that homes, businesses and other buildings accounted for at least 95% of new solar deployment.
Ministers said the figures showed households and businesses were responding to energy security concerns and volatile fossil fuel prices, particularly following the war in Iran. Official figures also showed nearly 23,000 new installations in April 2026, with nine of the ten strongest months for solar deployment having taken place within the past year.
Ed Miliband, the Energy Secretary, said the figures showed Britain was generating more clean power and reducing exposure to international fossil fuel markets. The announcement comes as the Government continues to argue that its clean power programme is central to energy security, lower bills and industrial growth, despite continued political pressure over the cost and pace of net zero policies.
