The 2026 plug-in rules cover solar devices only. Batteries, and solar kits with a built-in battery, are outside them: the government response says battery-integrated products "remain outside the scope of the current framework", and the specification says a plug-in kit must not be used with a battery system.
What that means in practice
Home batteries that feed your house wiring need a fixed connection by a registered electrician, who also handles the network operator notice. EcoFlow's own UK pages for its STREAM batteries say the supplied cable has bare ends and must be hardwired by a certified, registered electrician.
And portable power stations?
A power station that you plug appliances into is fine: it's a big rechargeable battery with sockets. What you must never do is feed a power station's output back into a wall socket.
Not electrical advice. We compare products; we are not electricians. Before you connect a solar kit to your home, ask a qualified electrician to check the socket, the circuit and your consumer unit, and follow the maker's instructions.
Questions buyers ask before buying
Will it ever pay for itself?
On the government's figures an 800 W kit tilted south saves about £113 a year in a home where someone is in during the day. The cheapest register-listed kit we list is £449 (sold out at the seller today), so that is roughly 4 years, and panels usually last far longer. Your home will differ: check yours in six questions.
Is it really legal and safe to plug into a socket?
Yes in England, Wales and Scotland since 27 August 2026, for kits listed on the . We only recommend kits whose listing we could confirm, and each kit page shows it. The rules ask for a modern consumer unit and no extension leads; if your fuse box is old, get an electrician to check it first. Is plug-in solar safe?
My house doesn't face south.
East or west still works. The government's figure for an upright east or west wall is about £72 a year with the same kit. North-facing is the one case where it is rarely worth it, and our calculator says so. Every direction compared.
I rent, or I live in a flat.
Plug-in solar was designed with flats in mind: no roof, no installer. You need your landlord's or freeholder's permission, and when you move you unplug it and take it with you, telling the network operator both times.
Sounds complicated.
Fix the panels with the maker's brackets, plug the kit into an outdoor socket, and tell your network operator using the QR code on the label. No meter change and no installer for the kit itself.
Can't I add a battery to use it in the evening?
Not under the plug-in rules: batteries are outside them and need fitting by a registered electrician. A plug-in kit pays back fastest on power you use in the day. Are solar batteries safe and legal?
