Figures published by the government today also show that nine of the ten best-performing months for solar additions were in the last year.
Figures from the UK government show that April this year saw 22,733 new solar PV installations, bringing the total solar capacity to 22.3GW.
April 2026’s added 107MW contributed to an 11.2% increase since April 2025, with 2.3GW added solar capacity across 12 months. Figures published by the government today also show that nine of the ten best-performing months for solar additions were in the last year, after March saw the UK reach over 2 million installations.
Over 50% of the new installations added during April 2026 were domestic rooftop PV. Government tracking shows that of the UK’s 269,000 total installations in 2025, around 255,000 were on rooftops.

This means that 95% of all new solar was installed on rooftops last year. The government said this equates to a new rooftop system coming online every two minutes throughout 2025.
Energy secretary Ed Miliband said: “As we face a second fossil fuel crisis in five years, Britain is taking back control of their energy by generating more clean power than ever before. Record-breaking solar growth means greater energy security, lower exposure to volatile fossil fuel markets which we can’t control.”
