Sublet your home

Sublet your home

Subletting takes place when a leaseholder rents their home out to another a person. Under the terms of our leases, leaseholders are not allowed to short-let their property for a period of less than 90 days. 

How to register a sublet

If you would like to sublet your home, you need to register the following details within 21 days of the arrangement starting and pay a registration fee of £30.

  • a certified copy of the tenancy agreement with the subtenant
  • an alternative postal address so that the accounts and any other formal notices can be sent directly to you  
  • a copy of the gas safety certificate for the property
  • details of any managing agent you are using
  • a contact number for you, and your managing agent if you have one, in case of an emergency

Please send the above information via email to housing.enquiries@westminster.gov.uk or by post to Leasehold Operations, 137 Lupus Street, London, SW1V 3HE.

Note: Renewing an existing tenancy agreement with your subtenant does not require another registration fee. We only require a certified copy of the renewal of the tenancy.

What is short letting?

Short letting is when a property is let for anything less than 90 consecutive days. Any let shorter than this period, for example 1 night, or 2 weeks – would be in breach of your lease. Websites such as Airbnb and Booking.com are becoming more popular in facilitating these types of let, however please note that it is your responsibility to ensure you adhere by the terms of your lease. 

Leaseholders are not permitted to short-let their property as per the terms of the lease. While we do note the Deregulation Act (2015) allows short letting for a period of up to 90 days in a calendar year, your lease prohibits this and supersedes the law as it is a contract between the leaseholder, the property and the landlord.

If you are found to be letting your property on a short-term basis you may be liable for legal action which can lead to a fine of up to £20,000 and the future sale of your property could be affected.

Note: If you short-let your property, you are not covered by our current Building’s Insurance policy as this is a breach of your lease which invalidates your coverage.

Points to note

It is important to understand your legal obligations as a landlord. You will be responsible for your subtenant's conduct. Please ensure your tenancy agreement includes the same rules and regulations that apply to you as the leaseholder.

When subletting, you should be aware of your tenant’s rights and responsibilities. and your legal obligations for servicing gas appliances and arranging Legionella (opens new window) tests.

If the property is sublet to a company, registered social landlord or other such organisation, then their subsequent sublet will be a further letting. This must also be registered, with payment of a further fee of £30 and a certified copy of that agreement.
