Households across the UK continue to embrace solar power as the government accelerates its clean power mission to reduce Britain’s exposure to volatile fossil fuel markets following the outbreak of the war in Iran.

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 2 of those being rooftop solar on homes, showing households are increasingly choosing to generate their own power.

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.
