What is commonly known as an appeal is more correctly known as a proposal to alter the rating list. Proposals can be made on a number of grounds, including challenging the basic rateable value, an alteration to the property, or proposing a reduction from a specific date due to a particular event (such as changes to a street affecting traffic). When an appeal is made, it will first be discussed with the Valuation Office Agency, who will attempt to come to an agreement. If no agreement is reached, and the proposal is not withdrawn, it will be heard by an independent valuation tribunal.
