Before Listing a London Flat on Airbnb: The Leasehold, Mortgage and Insurance Checks

Before listing a London flat on Airbnb, establish whether the proposed use is allowed. Airbnb leasehold rules in London depend on your lease, alongside separate mortgage, insurance and planning requirements.

Work through these checks before accepting a booking. Keep the answers and supporting documents together so your solicitor, lender, insurer and manager can review the same proposed arrangement.

1. Read the Airbnb leasehold rules for your London flat

Start with the full lease and any variations. Look for clauses about subletting, use as a private residence, business activity, minimum letting periods and nuisance. A clause allowing one type of letting does not necessarily allow short stays.

The Leasehold Advisory Service explains that leases can permit long-term subletting while restricting short stays such as Airbnb. Ask a leasehold solicitor to interpret unclear wording against your intended use.

• Check whether letting the whole flat and hosting a room are treated differently
• Identify any minimum stay, consent or notification requirements
• Review rules on noise, shared entrances, keys and communal areas
• Ask what formal steps would be needed if the lease restricts the proposal

Do not rely on a neighbour already hosting or a previous owner saying it was fine. Your own lease and the proposed arrangement need checking.

2. Confirm who can give consent

Find out whether approval must come from the freeholder, a management company or another authorised party. A managing agent may handle the enquiry, but ask who has authority to approve the particular use.

Send a clear description: whole flat or room, expected stay lengths, annual availability, guest numbers and management arrangements. Request a written answer that refers to the relevant lease provisions.

The Leasehold Advisory Service's approvals guidance explains how consent responsibilities can operate in a right to manage building. The route depends on the building and lease. Do not assume an informal email changes a prohibition in the lease.

3. Check the mortgage conditions

Read the mortgage offer and current conditions, then ask your lender about the exact short-let proposal. Airbnb's UK hosting guidance tells owners with a mortgage or other loan to check restrictions on hosting or subletting.

Ask whether the existing product permits paying guests, whether written consent is needed and what limits apply. Do not assume that consent for a conventional tenancy also covers frequent guest stays.

Record any approval, expiry date, fees and conditions. If a different mortgage arrangement is required, speak to an appropriately qualified mortgage adviser before committing to bookings.

4. Arrange insurance for the actual use

Explain the proposed letting to your insurer or broker before guests arrive. Ask for written confirmation that the cover suits short stays, the booking channels you plan to use and any periods when the flat is empty.

GOV.UK's holiday-let guidance recommends dedicated holiday-let insurance, public liability cover, and suitable buildings and contents cover.

• Check how guest damage, theft, liability and loss of income are treated
• Confirm excesses, exclusions and security conditions
• Tell the insurer about key safes, smart locks and any third-party management
• Check the block buildings policy with the freeholder or managing agent

A block policy and your own contents or liability policy may cover different risks. Ask the insurer to identify gaps rather than assuming one policy covers everything.

Airbnb states that AirCover for Hosts does not replace suitable home or liability insurance. Review its terms alongside your own policy.

5. Separate planning permission from private consent

Greater London's planning exception allows residential premises to provide temporary sleeping accommodation for no more than 90 nights in a calendar year, subject to conditions. The accommodation provider, or at least one of multiple providers, must be liable for council tax for the relevant nights.

Count qualifying nights across all booking channels and previous providers in that year. Appropriate planning permission is required to go beyond the exception. Check any property-specific conditions or directions with your borough.

Westminster's explanation of the law is a useful starting point. The planning exception does not override a lease restriction, mortgage condition or insurance exclusion.

Our London 90-night planning guide explains the annual count and how to plan legally available nights. Resolve permissions before using that calendar commercially.

6. Confirm council tax and rating responsibilities

Ask the council to confirm your council tax position and any effect on discounts or exemptions. If you rely on London's planning exception, the council-tax liability condition needs particular attention.

Business rates are a separate assessment, not an automatic result of creating a listing. GOV.UK sets out the English self-catering criteria: availability for at least 140 nights in the previous 12 months, actual commercial letting for at least 70 nights, and intended availability for at least 140 nights in the next 12 months.

These rating tests do not grant planning permission or extend London's annual allowance. Discuss the interaction with your council and a qualified adviser before changing how the property is treated. Keep booking, availability and income records.

7. Put guest safety in place

Complete a suitable fire risk assessment, record it and act on its findings before welcoming paying guests. Review escape routes, fire doors, alarms and guest instructions in the context of the flat and the building.

The Home Office's small paying guest accommodation guide covers suitable individual flats, with exceptions for more complex premises. Co-operate with those responsible for communal fire safety and get competent help where needed.

Where relevant gas appliances are provided, arrange maintenance and annual gas safety checks by a suitably qualified Gas Safe registered engineer. HSE's guidance includes holiday accommodation and explains how responsibilities should be set out when an agent is involved.

Check electrical safety, smoke and carbon monoxide precautions, water hygiene and safe furniture. Confirm any inspection or certification requirements for the actual arrangement with competent contractors and the relevant authority.

Give guests clear emergency instructions and a reliable contact. Put responsibility for inspections, repairs, records and between-stay checks into the management agreement.

Keep a pre-listing evidence file

Before opening the calendar, bring the key checks together:

• Lease review and any required formal consent
• Lender confirmation covering the intended short-let use
• Insurance documents and relevant block-policy confirmation
• Planning position, council tax status and annual night record
• Fire risk assessment, safety records and completed remedial work
• Named responsibilities for guest support and property checks

Recheck the file when the use, manager, mortgage or policy changes. GOV.UK currently describes England's national short-let registration scheme as not yet in force, with a March 2027 start expected. Monitor official guidance rather than treating that timetable as guaranteed.
