Apart from properties that are exempt from business rates, each non-domestic property has a rateable value which is set by the valuation officers of the Valuation Office Agency (VOA).
They draw up and maintain a full list of all rateable values, available at www.gov.uk/government/organisations/valuation-office-agency. The rateable value of your property is shown on the front of your bill.
This broadly represents the yearly rent the property could have been let for on the open market on a particular date. For the revaluation that came into effect on 1 April 2023, this date was set as 1 April 2021.
You can estimate your business rates by multiplying the rateable value by the correct ‘multiplier’ (an amount set by central government).
The valuation officer may alter the value if circumstances change. The ratepayer (and certain others who have an interest in the property) can request a change to the value shown in the list if they believe it is wrong, through the reformed Check, Challenge, Appeal (CCA) process. Full details on the CCA process are available from the VOA or from www.gov.uk.
