Section 1

Legal vs Illegal Airbnb Rent to Rent

Airbnb rent to rent is frequently confused with illegal subletting. The distinction is straightforward:

Illegal: Renting a property and listing it on Airbnb without the landlord’s knowledge, without mortgage consent, or in violation of lease terms. This is deceptive subletting and is illegal. For more detail, see getting mortgage consent for rent to rent.

Legal: Entering a properly documented Company Let Agreement with the landlord that explicitly permits short-term subletting, after confirming mortgage consent and headlease permissions are in place. This is a legitimate business arrangement.

✅ The Core Principle Legal Airbnb rent to rent is transparent, contractual, and fully documented. The landlord knows exactly what you are doing, has formally agreed to it, and their mortgage permits it. There is nothing hidden and nothing deceptive about a properly structured arrangement.

Section 2

The 5 Checks You Must Complete

Written Permission for SA Use in Your Contract

Your agreement with the landlord must explicitly permit short-term letting and Airbnb-style subletting. A general subletting permission is not sufficient — the contract must specifically reference short-term letting or serviced accommodation use. Without this in writing, nothing else matters.

Landlord’s Mortgage Consent for SA

Standard buy-to-let mortgages prohibit short-term letting. The landlord must check their mortgage terms and obtain explicit consent from their lender for SA use. Many lenders will require a switch to a specific SA mortgage product. This is the landlord’s responsibility — but you must confirm it is resolved before signing anything. If the mortgage does not permit SA, the arrangement cannot proceed legally.

Headlease Permission (Leasehold Properties)

For leasehold properties — most flats and apartments — the headlease between the landlord (leaseholder) and the freeholder will contain terms on permitted use. Many modern leaseholds explicitly prohibit short-term letting. Some define it as any letting of less than 6 months. You must read the relevant headlease clauses before committing to any SA deal on a leasehold property. Failure to do this is the most common legal error in SA rent to rent.

London 90-Day Compliance (London Properties Only)

In Greater London, the Deregulation Act 2015 restricts entire-property short-term letting to 90 nights per calendar year without planning permission. If you exceed 90 nights with a London property, you need planning permission for a change of use to short-term let. Track your nights carefully if operating in any London borough.

SA Licensing (Scotland and Emerging Requirements)

Scotland introduced mandatory short-term let licensing in 2023. All SA operators in Scotland must hold a licence from their local council. Similar schemes are under active consideration in other parts of the UK. Check the current position in your specific local authority area and keep up to date with new licensing requirements as they are introduced.

Section 3

The London 90-Day Rule — Fully Explained

The 90-Day Rule

Under the Deregulation Act 2015, entire dwellings in Greater London may be let on a short-term basis for up to 90 nights per calendar year (1 January to 31 December) without planning permission. For more detail, see planning permission requirements.

Exceeding 90 nights requires planning permission for a change of use to short-term let use. Airbnb and other platforms are required to automatically cap entire-property London listings at 90 nights per year unless the host can demonstrate they have planning permission for short-term use.

What counts towards the 90 nights? Entire-property lets where the host is not present. Individual room lets where you live in the property do not count. Corporate lets where the stay exceeds 90 consecutive nights may be excluded — seek specific planning advice on this. For more detail, see corporate lets for rent to rent.

Managing the 90-day limit: Airbnb automatically applies the cap to London listings. To maximise use of your 90 nights, target higher-value leisure bookings. Fill the remaining months with corporate lets (which may not count towards the limit) or use Booking.com (which does not enforce the cap — but legal responsibility remains yours).

Section 4

The Leasehold Problem — Why Most City Centre Flats Don’t Work for SA

The majority of city centre apartments — the most desirable properties for SA — are leasehold. And the majority of modern leaseholds contain clauses that effectively prohibit short-term Airbnb-style letting.

Common leasehold clauses that cause problems:

“The property shall not be let for any period of less than six months”
“The property shall be used as a single private dwelling only”
“No commercial use of the property is permitted without freeholder consent”
“Holiday letting is not permitted”

⚠️ Always Read the Headlease Before Committing Ask the landlord for a copy of the relevant headlease sections (specifically the user restrictions and alienation clauses) before committing to any SA deal on a leasehold property. Never proceed on the landlord’s verbal assurance that “it should be fine”.

Section 5

Consequences of Getting It Wrong

Violation	Consequence
SA without written contract permission	Agreement unenforceable, immediate termination right for landlord
Landlord mortgage not consented for SA	Landlord in breach of mortgage — lender can demand immediate repayment
Headlease violation	Freeholder injunction, legal costs, lease forfeiture risk for landlord
London 90-day rule exceeded	Planning enforcement notice, requirement to cease short-term use
No SA licence (Scotland)	Criminal offence — fine and requirement to cease operating
No gas safety certificate	Criminal offence — up to £6,000 fine per property

Frequently Asked Questions

Can I do Airbnb rent to rent on a leasehold flat?

Sometimes — but most leasehold flats have headlease clauses that prohibit short-term letting. You must read the headlease user restriction and alienation clauses before committing to any SA deal on a leasehold property. If the headlease permits it (or can be varied with freeholder consent), and the landlord’s mortgage also permits SA, then it is possible. In practice, the majority of modern leasehold city centre flats cannot be used for Airbnb due to headlease restrictions.

Does the London 90-day rule apply outside London?

No — the 90-day rule is specific to Greater London under the Deregulation Act 2015. Outside London, there is no national equivalent restriction on the number of nights you can let a property on a short-term basis. However, local councils outside London are increasingly introducing their own short-term let policies and licensing schemes, particularly in areas with high tourism. Always check the planning and licensing position in your specific local authority area.
