2025: Another Record-Breaking Year for Rooftop Solar

New government data published today shows that 2025 was the strongest year on record for solar power, 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 the roofs of 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. There were nearly 23,000 new installations in the last month alone – and more than 1 in 2 of those being rooftop solar.

The figures show households are increasingly choosing to generate their own power.

Installations Up, Costs Down

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%.
