Government data published on 27 August 2026 showed nearly 172,000 solar installations had been fitted across the UK since the start of 2026. Nearly 28,000 installations were completed in July 2026, described as the third-highest month on record behind March and June, with more than 19,800 of those on rooftops. Rooftop systems accounted for more than 7 in 10 July installations. The Department for Energy Security and Net Zero said installations rose in every UK nation and English region over the previous 12 months.

The first regional breakdown listed the South East top with 22,628 installations in 2026, taking the total to 305,101, up 14% since the previous July. The South West had 17,539 this year (total 271,400, up 13%), the East of England 18,109 (241,195, up 15%), the East Midlands 15,981 (182,606, up 17%) and the North West 15,927 (186,253, up 16%). Wales rose 18%, Scotland 14% and the North East 11%.

Energy Minister Michael Shanks attributed the growth to households seeking to cut energy bills, citing the Warm Homes Plan. The department said retailers including Currys, B&Q, Screwfix and Amazon were preparing to offer plug-in solar panels after government changes.
