Getting your landlord to agree to plug-in solar is often more straightforward than people expect. The key is asking in the right way. Landlords who say no to vague requests about “putting solar panels on the property” often say yes when they understand exactly what is involved, that nothing permanent happens, and that it can all be removed when you leave.
Here is exactly how to approach it.
Why you need to ask at all
Even though plug-in solar systems are portable and removable, most tenancy agreements require written permission for any external fixtures. Technically, attaching a bracket to a balcony railing or wall constitutes a fixture, however temporarily. Going ahead without permission puts you in breach of your tenancy agreement, which is a situation worth avoiding regardless of how minor the installation is.
The good news is that the Renters Rights Act 2025 provides a legal framework under which landlords cannot unreasonably refuse reasonable requests for home improvements. A portable, removable solar system that saves money and reduces carbon emissions is about as reasonable as home improvements get. If your landlord refuses without good grounds, you have options.
Write to your landlord before you buy anything
Do not buy the kit and then ask permission. Ask first. If the answer is no, or requires negotiation, you want to know that before you have spent £500. Write to your landlord by email so you have a record of the request and any response.
Your letter or email should cover:
- What you want to install: one or two solar panels and a microinverter, connecting to a standard socket
- Where you plan to position the panels: be specific about whether it is the balcony railing, garden fence or another location
- That the system is fully removable and portable with no permanent fixings to the building structure
- That you will restore everything to its original condition when you leave
- That the system complies with UK regulations under BS 7671 Amendment 4
- A brief note on the financial benefit: up to £180 per year saving on your electricity bills
Keep the tone factual and positive. You are not asking for something unusual. You are informing your landlord of a portable energy-saving measure and giving them the information they need to say yes.
If your landlord asks questions
Common questions landlords ask:
Will it damage the property? No. Railing clamp brackets do not drill into or permanently alter the railing. They can be removed leaving no trace. If you are using a wall bracket, you can offer to fill and paint any drill holes when you leave.
Will it affect the building’s electrics? No. The system connects to a standard socket. It does not interact with the building’s wiring in any way that requires modification to the consumer unit or any fixed electrical installation.
Will it affect the building’s insurance? Unlikely for a portable system, but worth your landlord checking with their insurer. You should also check your own contents insurance.
What happens when you leave? The panels, brackets and cable come with you. Nothing is left behind.
If your landlord says no
Ask for written grounds for refusal. A landlord who says no without specifying reasonable grounds is on weak footing under the Renters Rights Act 2025. Aesthetic preference alone is not generally considered a reasonable basis for refusal.
If you cannot reach agreement, Citizens Advice can advise on your rights. The Private Rented Sector Ombudsman is also available as an escalation route. Climate Minister Katie White has said the government will consider changes to the law if landlord refusals become a widespread problem.
Leaseholders: an extra step
If you own a leasehold flat rather than renting, you may need consent from your freeholder or residents management company in addition to navigating your lease terms. Check your lease before doing anything else. Some leases explicitly permit or prohibit external fixtures. If yours is silent on the matter, a formal written request to your freeholder is the right approach.
