UK Plug-In Solar: Consultation Closes, Commencement Still Unset
By Daniel Okafor · Last reviewed The UK government's consultation on legalizing sub-800 W plug-in solar — launched by DESNZ on 16 June 2026 — has closed for responses. The proposed route works through amendments to G98 and BS 7671 plus an interim product specification. Until final regulations and a commencement date land, socket connection remains not verified in force.
The United Kingdom's path to legal plug-in solar has completed another step: the Department for Energy Security and Net Zero's consultation on regulatory amendments and an interim product specification, opened on 16 June 2026, has closed for responses. The framework it describes follows the government's March announcement — qualifying systems below 800 W connecting to standard domestic sockets without an electrician — and works through the machinery that governs small generators in Britain: Engineering Recommendation G98, the wiring regulations in BS 7671, and a product specification drawing on commissioned safety research.
The technical direction is notable for how closely it tracks the German template while adding its own conditions. The interim specification focuses on battery-free systems, and the consultation examines inverter behaviour, protection against hazardous live pins, cable and plug design, and grid settings — the same safety analysis that underpins Germany's millions of installed systems, translated into UK terms. Northern Ireland is being considered separately.
What has not happened is commencement. A closed consultation is evidence of direction, not law in force: retailers are already selling continental-style kits in the UK, but plugging one into a British socket remains outside the current rules until final regulations land and take effect. The honest buyer's position is unchanged — research now, connect when the route commences. Our UK page tracks the current status, Ofgem's price-cap arithmetic for what a system would save, and the DNO notification question that the G98 amendments will settle.
