After each revaluation there is a period of
transition. No bill is allowed to increase or decrease by
more than a set percentage. Any property with a large
increase or decrease in its rateable value will come under the
transitional relief scheme, which has the effect of phasing the
valuation in over a period of time. If transitional relief applies
to your rates bill, it will be applied automatically. Further
