Getting Freeholder Permission for Balcony Solar in a Leasehold Flat

If you own a leasehold flat, you probably need your freeholder or management company's permission before mounting solar panels on your balcony. This is separate from planning permission (which you almost certainly don't need — see our planning guide).

Most leases include a clause about not making alterations to the exterior of the building without consent. A solar panel on a balcony railing technically falls under this — even though it's portable and non-structural.

Here's how to get that permission efficiently.

Check Your Lease First

Before contacting anyone, read the relevant section of your lease. Look for clauses about:

• Alterations to the exterior — does it distinguish between structural and non-structural changes?
• Items on balconies — some leases restrict what you can place on or hang from balconies
• Written consent requirements — does it say consent "not to be unreasonably withheld"?

That last phrase is key. If your lease says consent cannot be unreasonably withheld, your freeholder has to give a good reason for refusal — not just say no.

Writing the Request

Email your freeholder, managing agent, or residents' management company. Keep it short and factual:

Subject: Request for consent — portable solar panel on balcony

Include:

• Your flat number and lease reference
• What you want to install: a plug-in solar panel (400W or 800W), mounted on the balcony railing with a non-penetrating clamp
• That it's portable and fully reversible (no drilling, no structural changes)
• That it complies with BS 7671 Amendment 4 and the BSI product standard
• That the UK government confirmed plug-in solar as legal on 15 March 2026
• That you will complete the G98 DNO notification
• A request for written consent under the terms of your lease

Attach a photo of the proposed mounting location and a link to the specific kit (e.g. the EcoFlow STREAM) so they can see exactly what you're proposing.

Common Objections and Responses

"It will affect the building's appearance." A single panel on a balcony railing is less visually intrusive than satellite dishes, air conditioning units, or window boxes — all of which are commonly permitted. If the building already has any of these, the aesthetic argument falls apart.

"We haven't received guidance from our insurers." Offer to provide the BSI product standard reference once kits are certified. A government-endorsed, standards-compliant system is insurable. Ask them to check with their insurer rather than assuming.

"Fire safety concerns." In buildings under 18 metres, a balcony-mounted solar panel presents no fire safety risk — the panel is tempered glass and aluminium. For taller buildings, see our fire risk guide for the nuances.

"We need to do a structural assessment." For a clamp-on balcony panel weighing 10-12kg, this is disproportionate — it's lighter than a large plant pot. If they insist, a brief statement from a structural engineer costs £50-100 and will confirm no impact.

"The board hasn't discussed it yet." Ask when the next board meeting is and request it be added to the agenda. If no meeting is scheduled, ask for the timeline for a decision.

If They Don't Reply

Managing agents are notorious for slow or no responses. If you don't hear back within 21 days:

1. Send a follow-up email referencing your original request and the date sent
2. State that under the lease terms, you're seeking consent that should not be unreasonably withheld
3. Request a response within 14 days
4. If still no response, send a formal letter by recorded delivery

Persistent silence can constitute deemed consent under some leases — check yours for the specific terms. If your lease doesn't address this, silence is just silence, and you'll need to keep pushing.

Can They Charge You?

Some freeholders charge an administration fee for consent applications — typically £50-250. Check whether your lease permits this. If it does, you'll likely have to pay. If it doesn't, push back.

A fee of £50-100 is annoying but manageable. Fees of £250+ for a simple, non-structural, reversible change are arguably unreasonable — especially when the government has specifically endorsed plug-in solar as a consumer right.

The Residents' Association Route

If you have a residents' association or management committee, raising the issue there can be more effective than going through the managing agent. If several residents want solar panels, a collective approach is harder to refuse and shares the administrative burden.

Consider proposing a building-wide policy that permits balcony solar panels of up to 800W, subject to G98 notification — this saves future residents from having to make individual applications.

The Bottom Line

Getting freeholder permission for balcony solar is an administrative hurdle, not a legal one. The government has confirmed plug-in solar is legal. Planning permission isn't needed. The only barrier is your lease terms — and those typically require consent that cannot be unreasonably withheld.

Write a clear, factual request. Reference the government announcement. Attach the product details. Follow up if you don't hear back. Most freeholders will consent once they understand what's actually being proposed.
