Short Letting a Leasehold Flat: Lease, Block & Insurance UK
Short letting a leasehold flat needs three things lined up before insurance will work: a lease that allows it, a block buildings insurer that knows about it, and your own policy for everything the block policy doesn't cover. Many residential leases restrict use to a private residence or ban letting for less than a set period, and tribunals have treated Airbnb-style letting as a breach of that kind of covenant. The building itself is normally insured by the freeholder or management company under one block policy, so undeclared short letting can put that policy at risk and cause problems for every flat in the building. As the leaseholder, you insure your contents and furnishings, your liability to guests, guest damage and lost booking income. Miller & Partner places short-let cover for leasehold flats, including where mainstream insurers have declined.
Key facts at a glance
- Check the lease first. "Private residence only" and minimum letting terms are common, and short letting can breach them.
- The freeholder usually insures the building, under one block policy for every flat.
- The block insurer needs to know. Undeclared short lets can breach its occupancy terms.
- You insure your own contents, liability and income, not the structure.
- Any extra block premium caused by short letting can be recharged to you through the service charge.
- Breach of the lease can lead to forfeiture proceedings, so consent matters more than the insurance.
Can I short let a leasehold flat?
Look for clauses about use of the flat, subletting and nuisance. In Nemcova v Fairfield Rents (2016), the Upper Tribunal held that letting a flat on short stays breached a covenant to use it only as a private residence. Before a landlord can forfeit a long residential lease for breach of covenant, the breach normally has to be determined by a tribunal or court first, but that is not a process anyone wants to go through.
If the lease is unclear or silent, ask the freeholder or managing agent for written consent. Some freeholders agree subject to conditions such as minimum stays, guest numbers or proof of public liability insurance.
Who insures the building in a block of flats?
Block policies are underwritten on the basis of how the flats are occupied. Many are written for owner-occupiers and long-term tenants, with short lets either excluded, limited or loaded. If short letting is happening and the block insurer hasn't been told, a claim anywhere in the building could be challenged. See our block of flats insurance guide for how these policies work.
What does a leaseholder need to insure for a short let?
| Cover | Block buildings policy (freeholder) | Your short-let policy (leaseholder) |
|---|---|---|
| Structure and common parts | Yes, if short-let use is declared | No |
| Contents and furnishings | No | Yes |
| Your improvements to the flat | Sometimes, depending on the wording | Yes, where the block policy doesn't cover them |
| Liability to guests | No | Yes |
| Damage by guests | Structure only, subject to its terms | Yes, contents and your fixtures |
| Lost booking income | No | Yes |
If you run several units or let through a company, see our guide to serviced accommodation and rent-to-rent insurance.
Why do insurers decline short-let flats?
- Escape of water into other flats. Guests unfamiliar with the flat cause leaks that damage neighbours below, which drives liability claims.
- Noise, nuisance and security complaints. Shared entrances and key codes create disputes with other residents.
- Unclear lease position. Without evidence that short letting is permitted, many insurers won't quote at all.
- Previous claims or refusals. See short-let insurance after a refusal and short-let insurance after a claim.
This is where the Insurability Framework™ does its work: we put the lease, the freeholder's consent and the block insurer's position in front of the underwriter alongside your controls, so the decision rests on evidence rather than a tick box.
What if the freeholder or block insurer says no?
- Ask what conditions would make it acceptable. Minimum stays, guest limits and evidence of your own liability cover often change the answer.
- Offer to cover any extra block premium. A loading recharged to you is better than a breach.
- Consider medium-term lets. Lets of a few months to contractors or relocating staff may sit within the lease where nightly letting doesn't. Check the wording.
- Take legal advice on the lease. Covenant wording varies, and a solicitor's view is worth having before you invest in furnishing a flat to let.
How do I set up short-let cover for a leasehold flat?
- Read the lease. Find the use, subletting and nuisance clauses, and take advice if they are unclear.
- Get written consent. From the freeholder or managing agent, including any conditions.
- Confirm the block insurer has accepted short-let use. In writing, with any loading agreed.
- Insure your side. Contents, liability, guest damage and loss of income, with your improvements included where needed.
- Keep the building onside. House rules, noise limits and a contact for neighbours avoid the complaints that end consents.
Frequently asked questions
Only if your lease allows it or the freeholder consents. Many leases restrict use to a private residence or set a minimum letting period, and tribunals have treated short-term letting as a breach of that kind of covenant. Check the lease before you list.
Yes. Even if the lease allows it, the freeholder needs to tell the block buildings insurer. Undeclared short letting can breach the block policy's terms and put claims across the building at risk.
It covers the structure and common parts, provided the insurer knows about the short letting and has accepted it. It does not cover your contents, your liability to guests, guest damage to your furnishings or your lost booking income. You need your own policy for those.
Often, yes. If the block insurer adds a premium because of your short letting, the lease may allow the freeholder to recover it from you through the service charge. Agreeing this up front avoids disputes later.
The freeholder can take action, which can include seeking forfeiture of the lease once the breach has been determined by a tribunal or court. Your insurer may also refuse claims connected to an unlawful use. Insurance cannot cure a lease breach.
The block policy may cover damage to the building, subject to its terms and excess. Damage to the neighbour's own contents may lead to a liability claim against you, which your short-let policy's liability section should cover. Leak detection and clear guest instructions reduce the risk.
It depends on the block policy. Some cover landlord's original fixtures only, leaving your upgrades uninsured. Check the wording with the managing agent and add leaseholder's improvements to your own policy if needed.
Yes. Specialist markets will consider it when the lease, the freeholder's consent and the block insurer's position are evidenced. Disclose the previous refusal and the reason.
