Plug-in solar with a battery
Not on a socket – yet. The rules that made plug-in solar legal on 27 August 2026 cover solar generation only. Batteries such as the EcoFlow STREAM range are on sale, but they need to be installed properly rather than plugged into any socket.
What to do now
- Buy a solar-only kit now and size it to your daytime use. Without a battery, a two-panel 800W kit is the sweet spot for most homes.
- If you might add a battery later, a brand with a battery range (EcoFlow, Hoymiles, Octopus) keeps the door open.
- Ignore listings that sell “plug-in battery” bundles for socket use – that isn't covered by the current rules.
We'll add plug-in battery bundles to the price table as soon as they're allowed.
Quick answers
Can I plug a battery into a socket with plug-in solar?
Not yet. The UK rules that came in on 27 August 2026 cover plug-in solar only. Battery systems still have to be installed properly.
Will plug-in batteries be allowed?
Industry groups are pushing for it and products are being developed for the UK. Octopus has said it will pair plug-in solar with its plug-in 'Nook Cube' battery from early 2027.
