> Update, 10 August 2026: This has moved on a lot since we wrote it. The government's response landed 16 July, SI 2026/848 is made, and 27 August is now a confirmed legal date — see the legal confirmation post and today's rundown of which retailers are actually ready. The "still waiting for a response" framing below is kept for context but is no longer current.
The one-line answer
Not yet — but it's genuinely close now. As things stand today, you still can't legally buy a solar kit and plug it straight into a UK wall socket. What's changed is that we now have real dates on the calendar instead of vague government promises.
Forget the "it's legal now" headlines from April
A few sites ran with "plug-in solar is legal in the UK" back in April 2026, off the back of BS 7671 Amendment 4. That update is real, but its main practical content was a new chapter on battery storage wiring — it didn't touch the actual rule stopping you from plugging generation equipment into a normal socket. That rule sits in a separate piece of law, and it's still there.
What's genuinely happened so far
- March 2026 — Government publicly commits to legalising plug-in solar, also widely known as balcony solar (same tech, European name — one or two small panels and a microinverter).
- 15 April 2026 — BS 7671 Amendment 4 published. Useful groundwork, but not the enabler some coverage claimed.
- 16 June 2026 — DESNZ opens the consultation that actually matters: a proposed change to the Plugs and Sockets etc. (Safety) Regulations 1994, plus a new interim safety spec for kits.
- 30 June 2026 — That consultation closes.
- 22 July 2026 — Government's response is due. This is the date to watch.
So can I plug mine in yet?
No. Selling or using a kit that plugs into a normal socket is still against the rules until the new regulations are actually in force. Retailers like Amazon, B&Q, Currys and Lidl have all said they're ready to stock kits — the hardware exists, it's the paperwork that's still catching up.
What is legal right now is exactly what's always been legal: an 800W system hardwired in by a registered electrician, with your network operator (DNO) notified under G98. Same process as a small roof array, no shortcuts yet.
When will I actually be able to plug one in?
Realistically, autumn 2026 at the earliest. The government has said it wants to move quickly once the 22 July response lands, but the regulations still need finalising, and manufacturers need to get kits certified against the new spec before shops can sell them properly. Anyone promising a firm date before then is guessing.
