Britain sees record solar growth as households chase cheaper power amid soaring fossil costs

Government statistics reveal that 142,536 solar projects were commissioned in Great Britain during the first half of 2026, marking the most installations in any six-month period since the 2011 boom that featured the Cornwall tin-mine solar farm. While rooftop panels dominate the new builds, they account for just under one-third of the nation's overall solar capacity. Energy retailers report dramatic growth: E.ON Next recorded a 151% increase in home solar uptake compared with the same period last year, and Octopus Energy noted a 54% rise in March sales after Middle-East conflicts drove up oil and gas prices.

The government also reported a 21% rise in applications for its boiler-upgrade scheme, and recently boosted heat-pump grants from £7,500 to £9,000, while Andy Burnham announced a VAT cut on electricity to make heat-pump operation cheaper. Larger solar farms such as the 373 MW Cleve Hill project and the upcoming 800 MW Springwell farm illustrate the expanding utility-scale market, and new legislation will allow renters and flat-dwelling households to install balcony panels by August's end.
