Solar panels in London

The Mayor of London aims to install 1GW of new solar by 2030 - that's enough to power 250,000 homes. It's essential to help the city reach net zero emissions, but so far uptake has been much lower than the rest of the country.

Tall buildings, limited roofspace and uncertain policies have made installing solar PV in London a challenge. But we're determined to turn that around.

Going solar can save you around £400 a year on energy bills, giving an average 15 year payback. The lifetime cost per unit of solar electricity is 8p per kWh, compared to 17p (and rising!) from the grid.
