Do you need an electrician for plug-in solar?

Whether you need an electrician for plug-in solar comes down to a single distinction: how the system is connected. A genuinely plug-in connection and anything involving fixed wiring or a dedicated circuit are treated very differently, and understanding that difference is the most important thing on this page.

One essential point first: plug-in solar cannot currently be legally sold, supplied or used in the UK, however it is connected. A Government consultation that could change this is open until 30 June 2026, and the rules around connection and notification are part of what is being assessed. We cover the detail on the UK legal status page. This guide is general information, not electrical advice, and it does not explain how to wire or modify anything.

The key distinction

A genuinely plug-in connection is one made through an existing, suitable connection point without altering the building's permanent electrics. Fixed wiring is the opposite: it is the permanent installation of the home — its circuits, cabling, consumer unit and the fixed connections within it. Adding a dedicated circuit, or making a permanent connection into that installation, is electrical work, and that is the point at which a qualified, registered electrician is needed.

This distinction is also why people sometimes describe plug-in solar as appealing: the idea is that it avoids fixed-wiring work. In practice, whether any particular product can be connected without such work — and whether that would be permitted in the UK — is exactly the kind of question the framework is still being settled on.

Plug-in connection vs fixed wiring

The table below summarises how the two differ in who can carry out the work and whether it is notifiable. It is a general comparison, not a statement that either is currently permitted for plug-in solar in the UK.

When professional help is recommended or required

Anything involving fixed wiring, a dedicated circuit, a consumer unit, or a change to your existing installation should be carried out by a qualified, registered electrician. The same is true if you are simply unsure whether a circuit and its protective devices are suitable for the load — a registered electrician can assess that and advise. Treat any uncertainty as a prompt to ask a professional rather than to proceed.

There is also a separate question of telling your network operator about any generation. How that applies to plug-in systems is among the things still being worked through; our guide on G98 notification explains the principle, and our guide on electrical safety covers why the connection is treated with care in the first place.

Why fixed wiring is notifiable

Certain electrical work in a home is notifiable, which means it must be done to recognised standards and certified or notified appropriately. Installing a new dedicated circuit is a clear example. A registered electrician can carry out and certify this kind of work, which is a large part of why fixed-wiring jobs are for professionals rather than do-it-yourself. The central standard any installation is measured against is BS 7671, the British Standard for electrical installations published by the IET.
