Quick answer

Plug-in solar is now a real Great Britain route, but suitability depends on the complete product, your property, electrical installation, mounting location, permissions and network requirements. Use the checks below before buying.

The system is designed around a standard UK plug and socket

The interim specification defines plug-in solar as using a manufacturer-supplied standard plug designed to BS 1363 and a compatible socket outlet.

Use the manufacturer-supplied connection

The device is intended to connect to the UK mains socket solely by the manufacturer-supplied plug. The complete system and instructions matter; consumers should not improvise the connection method.

Outdoor sockets need weather protection

Where the BS 1363 plug/socket is outside, the specification requires outdoor plugs and socket-outlets to provide at least IP55 ingress protection.

Photograph the exact socket you plan to use

A useful pre-screen should inspect the exact socket, not merely ask whether the home has a socket somewhere. Visible cracks, scorching or obvious damage should trigger further assessment rather than a green result.

Avoid improvised leads and adaptors

Plug-in solar should be used as the manufacturer specifies. The Solixir checker treats extension leads, multi-way adaptors and unclear connection arrangements as issues requiring a different route.
