Can a tenant sublet without permission? Subletting and Airbnb rules for landlords

Updated August 2026 · Applies to England · 6 minute read

A tenant renting out a room, or the whole property, on Airbnb, or moving someone else in without saying so, is one of the more common tenancy problems landlords discover by accident, often from a neighbour or a listing found online. The short answer is that a tenant normally cannot sublet, or put the property on a short-let site, without the landlord's permission. Here is what that depends on, and what a landlord can do about it.

What counts as subletting

Subletting is where the tenant grants someone else the right to occupy all or part of the property, in exchange for rent, while the tenant's own tenancy continues underneath. That occupier becomes the tenant's subtenant, not the landlord's tenant, with no direct legal relationship to the landlord. Letting the whole property short-term through Airbnb or a similar platform is treated the same way, because the tenant is granting paying occupiers use of the property without the landlord's knowledge or consent.

Is it actually against the rules, or just bad manners?

It depends on the tenancy agreement, but the starting assumption should be that it is a breach. Most assured shorthold agreements include a clause prohibiting subletting outright or requiring the landlord's written consent first, and it is that clause, not a general statutory ban, that makes unauthorised subletting a breach. Where an agreement is silent, the Housing Act 1988 fills the gap: it implies a term into periodic assured tenancies that, except with the landlord's consent, the tenant must not sub-let or part with possession of the whole or part of the property. Since the Renters' Rights Act abolished fixed terms, every assured tenancy is now periodic, so that backstop applies more widely than before. One important distinction: for a private tenancy this is a breach of contract, not a crime. Unauthorised subletting of a whole home by a council or housing association tenant is a criminal offence under separate social housing fraud legislation, but that law does not extend to private landlords and tenants. A landlord's remedy sits in tenancy law, covered below.

Subletting and taking in a lodger are not the same thing

Worth flagging briefly: a lodger shares the tenant's own living space, such as a kitchen or bathroom, which differs from subletting a self-contained room or the whole property to someone with exclusive use of it. Many agreements restrict both, but the legal analysis differs and a full comparison is beyond this guide. If your agreement only mentions "subletting", check it also covers lodgers.

Airbnb and short lets carry the same restriction, plus extra risk

A tenant does not need to move out to breach the tenancy - listing a spare room or the whole flat on a short-let platform while still living there, or while away, is enough. Undisclosed short-letting can also affect the landlord's buildings insurance, breach the conditions of a buy-to-let mortgage, and, for a leasehold flat, put the landlord in breach of the head lease or the freeholder's rules on short lets. None of that is the tenant's problem to manage, which is why the tenancy agreement needs to deal with it up front.

What a landlord can do about it

Start by raising it with the tenant and asking for the listing to end - many will comply once challenged. If not, the practical route is a Section 8 notice citing Ground 12, the discretionary ground covering breach of any tenancy term other than rent, with a two-week notice period. Where there is also disturbance to neighbours, Ground 14 (nuisance) can be added. Because both grounds are discretionary, evidence carries the case: the listing itself (screenshot it before it disappears), correspondence with the tenant, and any witness statements. Our Section 8 grounds guide sets out the full table of grounds and evidence, and our Section 8 notice guide covers serving the notice end to end.

Preventing it in the first place

The cheapest fix is a clearly worded clause prohibiting subletting, lodgers and short-let listings without prior written consent, rather than relying on the tenant knowing the implied statutory position. Check this clause is present in any agreement signed or renewed since the Renters' Rights Act changes, since periodic tenancies are now the only kind that exist and the clause is doing more work than before. Our tenancy agreement template guide covers what a compliant agreement should contain.

Frequently asked questions

Can a tenant sublet without the landlord's permission? Usually not. Most tenancy agreements prohibit it or require written consent, and periodic tenancies carry a similar implied term under the Housing Act 1988 even where the agreement is silent.

Is subletting without permission a criminal offence? Not for private tenants. That offence applies only to council and housing association tenants under separate social housing fraud legislation. For a private landlord it is a breach of contract, handled through the tenancy agreement and, if needed, a Section 8 notice.

Can a tenant list the rental property on Airbnb without asking? No. It is treated the same as subletting, is normally a breach of the tenancy, and can also affect the landlord's insurance, mortgage and, for leasehold flats, the head lease.

What can a landlord do about unauthorised subletting or Airbnb use? Raise it with the tenant first. If it continues, serve a Section 8 notice on Ground 12, adding Ground 14 if there is nuisance to neighbours, and back it with evidence.
