Sublet your home

Subletting takes place when a leaseholder rents their home out to another person. If you would like to sublet your home you need to register some details with us within 21 days of the arrangement starting and pay a registration fee of £30.

Please email housing.enquiries@westminster.gov.uk with the following information: 

  • 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.

Should you wish to send us hard copies of the above documents, please address this to Westminster City Council Leasehold Operations 137 Lupus Street, SW1V 3HE.

Points to note

It is important to understand your legal obligations as a landlord. You can find more information on The Residential Landlord and Agents website (opens new window).

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.

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.

You also need to be aware of 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.

Also, when subletting, you should be aware of your tenant’s rights and responsibilities. 

Short-letting

Under the terms of our leases, leaseholders are not allowed to short-let their property.

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 Air B’n’B 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. 

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.

Please note that 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.

If you are unsure about the above, please contact us on housing.enquiries@westminster.gov.uk or 0800 358 3783.
