If you think your valuation is wrong
The council has no influence over the national multiplier or rateable value against which your property is assessed.
Any enquiries about rateable values must be submitted directly to the Valuation Office Agency (VOA).
You can contact the VOA at gov.uk/contact-voa. If you are unable to use the online service you can also contact the VOA on 03000 501 501.
The valuation officer may alter the value if they believe that the circumstances of the property have changed. In certain circumstances the ratepayer (and certain others who have an interest in the property) may also propose a change in value. If the ratepayer and the valuation officer do not agree, the matter will be referred to an appeal by a valuation tribunal. Further information is available from the Valuation Office Agency
Please remember that appealing against your rating assessment does not entitle you to withhold payments due on your account.
