Rules and registration
Are plug-in solar kits legal in Great Britain?
There is no single yes or no. Five separate questions sit behind that one, and they are often confused with each other.

Rules can change
Great Britain is at an early stage of the plug-in solar category. 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, together with your property and the steps you take after connection.
1. Product status
Status attaches to a specific product in a specific supplied configuration, identified by a model code and reference. A similar-looking product is a different product. Check the live status and the documentation supplied with the kit rather than a screenshot or a marketing claim.
2. Electrical and system requirements
The manufacturer sets out how the kit must be installed and connected, including the supplied cable and connection method. Those instructions are the requirement — not a general rule of thumb, and not an alternative arrangement you have seen elsewhere.
3. Property, landlord and freeholder considerations
This is separate from the product. Renters normally need written landlord consent; leaseholders may also need the freeholder or managing agent. Buildings can have their own rules about anything fixed to a balcony, railing, roof or external wall.
4. Registration and notification
Expect a notification or registration step after connection, with the relevant network operator or official route. It is your responsibility, and it is not replaced by anything on this site.
5. Export-tariff eligibility
Separate again. Whether a supplier will pay for exported electricity from a system of this type varies, and should be confirmed in writing before you count on it.
What it means for you
- Identify the exact model code and register reference of the kit you are considering.
- Check the current status of that exact configuration, and note the date you checked.
- Read the full installation manual before ordering.
- Confirm your space allows secure, permanent-quality mounting.
- Get written permission if you rent, lease, or live in a managed building.
- Plan the post-connection notification or registration step in advance.
- Treat export income as £0 unless your supplier has confirmed eligibility and a rate.
- Do not assume a battery can be added.
