Strongest Q1 for Rooftop Solar Since 2012
The UK witnessed a remarkable surge in rooftop solar installations during the first quarter of 2025, recording 57,000 certified installations, the highest since 2012. March alone saw 21,000 installations, the most for any month since December 2015, driven by new building regulations in England that promote energy efficiency.
New Record for Solar Generation in April
On April 6, UK solar power generation set a new record, reaching 12.7 GW in a single day. The rise in solar deployment, now exceeding 18 GW, is fueled by both new-build homes and retrofits, with more than a third of March’s installations taking place on new properties.
Rooftop Solar Continues to Gain Momentum
The MCS certification body reports that the majority of small-scale PV installations are still retrofits, although the share of new-build installations is increasing. Solar Energy UK emphasized that consumer confidence in solar technology is growing, driven by the environmental and cost-saving benefits of solar energy.
MCS CEO Ian Rippin highlighted the sustained growth, saying, “Consumers continue to turn to solar panels for home-grown energy.” Solar Energy UK’s Gemma Grimes noted that while new builds play a growing role, retrofitting remains dominant, reflecting the public’s increasing faith in solar solutions.
