If the rateable value of your property changes significantly because of revaluation, your rates will change gradually. This is 'transitional relief'. After each revaluation, there is a period of transition. Bills cannot 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. If transitional relief applies to your rates bill, we apply it automatically.
See business rates relief on GOV.UK for details of rate increase limits and rate decrease limits.
