News & Policy
Balcony Solar News UK
Regulation, policy, and government announcements that affect balcony solar owners and those thinking about installing.
The UK’s legal position on balcony solar is now settled. Germany legalised plug-in solar panels (Balkonkraftwerke) years ago and has since passed 1.2 million installations; the UK followed on 16 July 2026, when the government published its consultation response alongside SI 2026 No. 848. That instrument comes into force on 27 August 2026, and from that date a plug-in solar device meeting the Interim Product Specification can lawfully be sold and plugged into a standard socket — no electrician, and no G98 notification for the device itself.
The practical position lags the legal one. As at late July 2026, no kit had yet been verified against the specification on the ENA Type Test Register, so nothing compliant was actually on sale, and the simplified DNO registration route was still being built. Anything bought before then is a conventional installation, not a plug-in one. This page tracks each development as it lands.
What Actually Changes on 27 August 2026
Plug-in solar becomes legal in the UK on 27 August 2026. The practical explainer: what the law actually permits from that day, what it leaves untouched — batteries, the Smart Export Guarantee, rooftop rules, planning and leasehold permissions — and the one thing you still cannot do, which is buy a verified kit.

Three Weeks Out, Still No Compliant Kit on Sale
With 22 days to go until legalisation, the ENA Type Test Register is empty and none of the seven named retailers has announced a launch date. Why nothing on sale today qualifies for the plug-in route, why the gap is sequencing rather than scandal, and what to do with the wait.

One Kit Per Circuit: The Rule Change Buyers Miss
The final specification allows one plug-in solar device per power circuit — not per household and not per socket. What a power circuit means in a UK consumer unit, why a ring final circuit counts as one, how many kits a typical home can take, and how to check without guessing.

Five Electrical Bodies Warn Over Plug-In Solar Rollout
The ECA, Electrical Safety First, the IET, NICEIC and SELECT issued a joint statement on 9 June 2026 urging caution over the rollout. We cover what they actually said, why the older-wiring concern is the serious one, and how much of it the final specification — published five weeks later — went on to address.

Batteries Not Included: The Awkward Gap in the UK's New Plug-In Solar Rules
The plug-in route arriving on 27 August 2026 covers panels plus a microinverter only — yet almost every premium kit sold in the UK today is built around integrated battery storage. We unpack the exclusion, what it means for EcoFlow, Zendure and Anker buyers, and how to choose between the two routes.
