An ‘interested party’ (usually the owner or occupier) is allowed to make a proposal to change the rating list where they are not satisfied with the level of assessment or any other part of their entry within the list. The grounds of a valid proposal will define the extent of any case brought before a hearing and must be carefully served. A proposal can often be made within the term of the rating list, and where the problem remains unresolved it becomes an appeal and may proceed before the valuation tribunal for a hearing.
