Rateable value
Every commercial property has a rateable value determined by the Valuation Office. The rateable value is a professional view of the annual rent for a property if it were available, vacant and to let on the open market. Rateable values are based on market rents at an earlier valuation date (“the antecedent date”) - a date specified by the government.
Statute prescribes the frequency for which rateable values are re-valued so that the values in the Local Rating List are kept up to date. The valuation date for the current rating list is 1 April 2024 which comes into effect on 1 April 2026.
See further details on the Revaluation page.

Find out the rateable value of a property
You can find out the rateable value of any business premises in a local authority area and see how it compares to other similar premises by postcode via the Valuation Office.
What to do if your rateable value is wrong
If you believe the rateable value, description or size of the property is wrong you need to appeal to the VOA
New builds and properties under construction
If your property is under construction or newly built, it may not have been assessed for local taxation purposes. If it is an existing property that is being converted or demolished and you want the rateable value reduced or the property removed from the rating list, please contact the Valuation Office.
If the works are complete and it is a new property you will need to provide details of the new property e.g. plans, dates etc, as well as your contact details to Harrow Council. You can do this by posting the documents to Harrow Council, Business Rate Office, PO Box 731, Harrow HA3 3RG.
