Can You Use Plug-In Solar? A Four-Question Check for Great Britain

Plug-in solar is legal in England, Wales and Scotland, but whether you can use it at your home depends on four things: whether you own or rent, what kind of building you live in, which nation you are in, and whether you have a fixed socket to plug into. Answer four questions below and you get a result with the rule behind it. Rules verified on 9 Nov 2026.

The Rules in Brief

• Legal in England, Wales and Scotland since 27 August 2026. SI 2026/848 reg. 1
• Output capped at 800 W AC, and no battery inside the plug-in unit. SI 2026/848 reg. 2(3)
• One device per home, plugged into a fixed wall socket, never an extension lead.
• You can fit it yourself, and you register it on myplugin.solar before you use it.

How the Result Works

Each result shows a status and the steps that follow, and every step carries the source it comes from.

If you are in Great Britain and own your home, the next steps are registering the device on myplugin.solar before you use it Electricity North West, plug-in solar, 2026, a check that your fixed wiring is sound under BS 7671 DESNZ interim product specification v2, §8.3.2, 2026, and one device per home.

If you rent or live in a leasehold flat, the rules are the same but you must get permission from the landlord or freeholder first. DESNZ interim product specification v2, 2026

A timber balcony, timber or certain other cladding, or a building under external wall remediation is not an allowed place to mount a kit. DESNZ interim product specification v2, §8.3.2, 2026

In Northern Ireland, the rule that allows plug-in use does not extend there, so the checker says it is not covered by the Great Britain rules yet. SI 2026/848 reg. 1

If there is no fixed socket you can reach without an extension lead, you need an electrician. Extension leads and adaptors are not allowed.

In England, a listed building or a conservation area means a planning check first. SI 2026/896 For Scotland and Wales we could not confirm the planning rule, so the checker says so rather than guess.
