Renters and flat owners can legally use plug-in solar in Great Britain since 27 August 2026 — the law was changed with exactly these households in mind. Legality is not the obstacle; permission is. If you rent, you need your landlord's written consent. If you own a leasehold flat, you need the freeholder's consent, and a freeholder cannot unreasonably withhold it under the Landlord and Tenant Act 1988. Flats are also excluded from some permitted development rights that houses enjoy, so check with your council too. A free-standing ground-mount or a non-drilled balcony clamp avoids most of these arguments entirely.
The government has been explicit that renters and flat-dwellers are a core reason for the change: these are the households that could never access rooftop solar. The catch is that removing a legal barrier does not remove a contractual one. This guide covers the permissions in the order you will actually hit them.
If you rent, what do you need?
Written landlord consent. Not a phone call, not a text you might lose — something you can produce at the end of the tenancy when the deposit is being discussed.
Almost every assured tenancy agreement contains a clause prohibiting alterations to the property without consent. Drilling brackets into an external wall or balcony rail is an alteration. Whether a clamp-on balcony mount counts is genuinely arguable, which is precisely why you want it in writing before rather than after.
The Renters' Rights Act 2025 reshaped the private rented sector in England substantially, but do not assume it gives you an automatic right to install generation equipment. Treat landlord consent as a requirement to be obtained, not a formality to be assumed. If in doubt, ask a housing adviser about your specific tenancy rather than relying on a general article — including this one.
What makes a landlord say yes:
- Reversibility. "No holes, and I will remove it and take it with me" answers most objections in one sentence.
- Certification. Name the kit and say it holds a compliant entry on the ENA G98 type-test register. That distinguishes you from someone importing an untested unit.
- Who pays. Make clear you are buying it, fitting it and taking it with you. The landlord is being asked for permission, not for money.
- The G98 notification. Say you will file it and send them a copy. It shows the network operator is being told properly.
- Insurance. Offer to confirm with your contents insurer that the equipment is covered.
If you own a leasehold flat, what do you need?
Freeholder consent, usually via the managing agent, and usually in the form of a licence to alter. The external walls and often the balcony structure itself are typically demised to the freeholder rather than to you, even where you have exclusive use.
The useful protection here is the Landlord and Tenant Act 1988, which prevents a landlord — including a freeholder — from unreasonably withholding or delaying consent where the lease requires it. "Unreasonably" is doing real work in that sentence. Grounds that are usually accepted as reasonable include:
- Structural loading on a balcony not designed for it.
- Risk of water ingress from fixings through a facade or membrane.
- Visual impact on the elevation of the building, particularly on a uniform frontage.
- Fire strategy on the external wall, which has become a far more sensitive question for managing agents in recent years.
Expect an administration fee. Some managing agents charge a couple of hundred pounds to process a licence to alter, which on a £599 kit can add roughly two years to your break-even. Ask what the fee is before you buy the kit, not after. That figure belongs in your payback calculation.
Do you need planning permission?
For most houses, wall-mounted or free-standing domestic microgeneration falls under permitted development and needs no application, subject to conditions — typically limits on how far equipment projects, and exclusions in conservation areas and on listed buildings.
Flats and maisonettes are the problem. They are excluded from some of these permitted development rights, which means what is automatic for a terraced house may require an application from the flat above it. There is no substitute for asking your local planning authority about your specific building. It is a free question and a five-minute call.
| Your situation | Landlord consent | Freeholder consent | Planning check |
|---|---|---|---|
| Freehold house, you own it | Not applicable | Not applicable | Usually permitted development; check if listed or in a conservation area |
| Leasehold flat, you own it | Not applicable | Yes, licence to alter | Yes — flats are excluded from some rights |
| Renting a house | Yes, in writing | Landlord's problem, not yours | Landlord should confirm |
| Renting a flat | Yes, in writing | Landlord obtains it, not you | Landlord should confirm |
| Free-standing in a private garden or yard | Still ask if renting | Rarely engaged | Usually the simplest case |
The pattern in that table is worth noticing. If you rent, you deal with your landlord and only your landlord — chasing the freeholder and the council is their job, not yours. Do not let a managing agent turn you into the applicant.
The route that avoids most of the argument
If you have any private outdoor ground — a yard, a patio, a strip of garden, even a flat roof terrace you can ballast rather than drill — a ground-mounted kit sidesteps the facade question entirely. Nothing penetrates a wall, nothing is fixed to the building, and the conversation changes from "may I alter your property" to "may I put a freestanding object on the ground".
The ledger currently lists two certified ground-mount options: the UKSOL Pro Compact 460W at £699 and the UKSOL Pro Duo 890W ground-mount at £849. The Duo is the better buy of the two on cost per watt by a wide margin. Full pricing is in the certified kit ranking.
On a balcony, look for a clamp mount that grips the rail rather than a bracket that bolts through it. It is a weaker argument for a landlord to refuse, and a much easier one to make good at the end of a tenancy.
Does G98 work differently in a flat?
No. The notification is about the electricity network, not the building's ownership. You tell your Distribution Network Operator that a generator has been connected, within 28 days, using the free G98 form. Your DNO is determined by where you are, not by whether you own the walls.
One practical point for flats: your supply comes off a shared riser, and your DNO records the connection against your meter point. Nobody else in the block needs to consent to the notification, and it does not require the freeholder's involvement. Walk through it in G98 notification, step by step.
How to ask, in one paragraph
Keep it short and make the answer easy. Something like: "I would like to install a plug-in solar panel on the balcony. It is a certified kit on the Energy Networks Association type-test register, it plugs into an ordinary socket, it needs no electrical work, and I will use a clamp mount so nothing is drilled. I will notify the network operator as required and send you a copy, and I will remove it and make good when I leave. May I go ahead?"
That paragraph pre-answers the four things a landlord or agent will worry about: is it legal, does it involve electrical work, does it damage the building, and who is responsible.

Frequently asked questions
Can renters install plug-in solar in the UK?
Yes, it is legal in Great Britain since 27 August 2026, and renters were a stated reason for the change. You will still need your landlord's written consent, because virtually every tenancy agreement restricts alterations to the property. A reversible, non-drilled mount makes that permission much easier to get.
Can my landlord refuse permission for balcony solar?
A landlord can refuse consent to an alteration under the terms of your tenancy. Do not assume any statutory right overrides that — get consent in writing before you buy. Offering a reversible clamp mount, naming a certified kit and confirming you will remove it at the end of the tenancy removes most reasonable objections.
Do I need freeholder permission for solar on a leasehold flat?
Almost always, yes, usually via a licence to alter from the managing agent. External walls and balcony structures are typically retained by the freeholder. Under the Landlord and Tenant Act 1988 that consent cannot be unreasonably withheld or delayed, but structural loading, water ingress, fire strategy and visual impact are all treated as reasonable grounds for objection.
Do I need planning permission for balcony solar on a flat?
Possibly. Domestic microgeneration on houses is usually permitted development, but flats and maisonettes are excluded from some of those rights, and conservation areas and listed buildings have their own restrictions. Ask your local planning authority about your specific building before you buy.
How much does freeholder consent cost?
It varies. Some managing agents process a licence to alter free; others charge an administration fee that can run to a couple of hundred pounds. On a £599 kit that can add around two years to your payback, so ask the number before you order anything.
What is the easiest option for a renter?
A free-standing ground-mounted kit in a private yard or garden, if you have one. Nothing is fixed to the building, so the alterations clause is barely engaged. Failing that, a clamp-on balcony mount that grips the rail rather than bolting through it.
Do I still need to notify the network operator if I rent?
Yes. The G98 notification is about the electricity network, not the building's ownership, and it applies whoever owns the property. It is free, takes about twenty minutes, and is due within 28 days of connecting.
Can I take it with me when I move?
Yes, and that is one of the genuine advantages over rooftop solar. A plug-in kit unbolts from its mount and moves house with you, so the payback clock keeps running in the next property. You will need to file a fresh G98 notification at the new address.
