Is plug-in solar legal in the UK?

Yes. Since 27 August 2026 you can buy a plug-in solar kit and plug it into a socket at home in England, Scotland and Wales. Northern Ireland is handled separately.

The rules in five lines

  1. 800W maximum output. The kit's microinverter can feed in up to 800W. One kit per home.
  2. Buy a complete, compliant kit. It must be listed as compliant on the Energy Networks Association (ENA) Type Test Register. Don't build your own from separate panels and inverters.
  3. Plug straight into a fixed socket. No extension leads, reels or adaptors. An outdoor weatherproof socket is ideal.
  4. Register it. Kits come with registration details (myplugin.solar) so your local network operator knows it's there – do it soon after installing.
  5. Solar only. Plug-in batteries aren't allowed on a socket yet.

Everything in our price table is sold as a complete kit, and we flag any we couldn't confirm on the ENA register.

Renting or in a flat? You'll usually need your landlord's or freeholder's OK before fixing anything to walls or railings. See plug-in solar for renters.

Quick answers

Is plug-in solar legal in the UK?

Yes, in England, Scotland and Wales since 27 August 2026. Northern Ireland has separate rules.

How big can a plug-in solar kit be?

The microinverter can feed in up to 800W. The panels can add up to more than 800W – many kits have 900–1,260W of panels – because the inverter caps the output.

Do I need an electrician?

No. A compliant kit is designed to be set up by you and plugged into an existing socket. You don't need MCS certification either.

Can I use an extension lead?

No. Plug the kit's own lead straight into a fixed socket – no extension leads, cable reels or adaptors.

Do I have to register it?

Yes. After installing, register the kit – set-up guides point to myplugin.solar – so your local electricity network knows it's there. Retailers advise doing it within 28 days.

Can I add a plug-in battery?

Not on a socket yet. The 2026 rules cover plug-in solar only; batteries still need a proper installation.
