United Kingdom solar installations reach record highs

Solar panel installations in the United Kingdom are experiencing a significant surge, with 142,536 new installations recorded in the first half of 2026. This brings the total number of installations to over 2 million, placing the country on track to surpass previous records. The growth follows a record-breaking 2025, which saw 269,000 completed installations.

Drivers for this increase include falling upfront costs and a desire among homeowners to reduce reliance on the grid. Additionally, new regulations set to take effect on 27 August will legalize plug-in solar panels. These small-scale, portable kits allow users to feed electricity into their homes via standard three-pin plugs rather than requiring professional electrical wiring. Retailers such as Lidl, B&Q, Currys, and Amazon have been working with the government to prepare for this market, though specific product launches and pricing are still being finalized to meet new safety requirements.
