Households across the UK are embracing solar power as the government accelerates its clean power mission.
Households across the UK are embracing 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 more than 27,000 solar installations were completed in March 2026 – the highest monthly total since 2012 – bringing the total number of solar installations across the UK to more than two million for the first time.
Solar capacity increased by 11.7% over the past year, adding 2.3 GW of clean, homegrown electricity to Britain’s energy mix. This growth means more British renewable power is being generated domestically, helping to protect families and businesses from international gas price shocks.
The record growth comes as the government steps up investment in solar power across homes, schools and communities to deliver its clean power mission and help cut energy bills. This includes:
This month saw a new record for solar generation, with National Energy System Operator data showing solar output passing 15 GW for the first time on Britain’s electricity system, underlining the pace at which clean, homegrown power is being rolled out.
Energy Secretary Ed Miliband said: 
The numbers speak for themselves – the highest monthly installation of solar in over a decade, rising capacity and more than 2 million solar installations now powering homes across Britain.  
This is our clean energy mission in action – helping families weather global energy shocks, bringing bills down, and getting Britain off the fossil fuel rollercoaster.
These installations build on the success of Great British Energy’s solar scheme, with the government backing the company to support a further 100 schools and colleges with rooftop solar installations this year.
In addition, subject to final approvals, the government is providing an extra £100 million for the Social Housing Fund, helping deliver up to 57,000 solar installations for households during this financial year.
