# UK legalises plug‑in balcony solar, rollout continues > Live situation record from CLSTR: https://clstr.news/situations/uk-plugin-balcony-solar-market > Updated: 2026-08-22T10:47:28.000Z. Sources: 44. Developments: 12. In May 2026, a low-cost DIY balcony solar kit entered the UK market, offering a plug-in solution via standard sockets. By mid-June, APsystems and UKSOL began supplying systems with module-level micro-inverters, and Lidl announced its own £500 kits. New safety rules allowed installations up to 800 W but required landlord consent and network-operator notice. A government-backed round-table involving retailers like B&Q, Currys, and Amazon promoted these panels as a way to cut bills for low-income households. On 27 August 2026, a statutory amendment to the Plug-and-Socket Safety Regulations officially legalised plug-in balcony panels, capping output at 800 W and lifting the ban on feeding electricity back into sockets while maintaining the battery prohibition. Retailers prepared stock expected to retail from approximately £400, with the Department for Energy Security and Net Zero forecasting annual savings of £70–£110. Leading up to the legalisation, UKSOL became the first company to have its products listed as compliant in the Energy Networks Association's Connect Direct database. Ahead of the August 27 rollout, retailers including Argos and City Plumbers confirmed availability, though some experts noted initial costs might exceed the £400 estimate. While the kits do not require professional installation or planning permission in England, Electrical Safety First advised consumers to ensure older Residual Current Devices (RCDs) are upgraded to Type A bidirectional models to safely manage reverse electricity flows. Environmental groups, including Friends of the Earth, welcomed the move, though some expressed concern that without subsidies, the technology might primarily benefit those who can already afford energy-saving measures. ## Claims - Households in Great Britain will be able to legally purchase plug‑in solar panels from August 27, 2026.
