Are plug-in solar kits legal in Great Britain?

Summary

What the plug-in solar category means in Great Britain, why the exact product configuration matters, and the checks to make before you buy.

What you will learn

  • Why the specific product configuration matters more than the product type
  • The difference between product status, property permissions and registration
  • What to check and where the responsibility sits

The category, in plain terms

Plug-in solar describes small, complete solar kits designed to be installed by the householder and connected without a full rooftop project. Great Britain is at an early stage of this category, and arrangements are specific rather than general.

That means it is not accurate to say the category as a whole is either permitted or prohibited. What matters is the exact product, in its exact supplied configuration, and the requirements that apply to it.

Product status is not the same as property permission

Four separate questions need answering, and they are often confused with each other: the product's own status and documentation; the electrical and system requirements set out by the manufacturer; permissions relating to your property; and the notification or registration step after connection.

A product that satisfies one of these does not automatically satisfy the others. A leaseholder or renter, for example, may need written permission regardless of the product.

What to do before you buy

Match the exact model code and supplied configuration to the documentation. Check the current register status rather than relying on a listing or a screenshot. Read the full installation manual before ordering, not after. Confirm who needs to give permission for your property.

We do not provide legal advice, and rules in this area can change. Treat this guide as a starting point for your own checks.

Safety and accuracy

Do not assume a similar-looking product carries the same status. Configuration differences matter.
