UK legalizes plug-in solar kits for homes

A new law allowing households in the United Kingdom to purchase and install plug-in solar panel kits came into effect on August 27, 2026, marking a significant shift in the country's renewable energy landscape. The legislation permits the sale of compliant solar systems with an alternating current output of up to 800 watts, which can be connected directly to a standard household socket using a three-pin plug. This change opens up solar power generation to a broader audience, including renters, flat owners, and those without suitable roofs for traditional installations.
