The non-domestic rates collected by billing authorities are paid into a central pool and redistributed to county and county borough councils and police authorities. Your council and police authority use their share of redistributed rate income, together with income from their Council Tax payers, revenue support grant provided by the National Assembly for Wales and certain other sums, to pay for the services they provide.

National Non-Domestic Rating Multiplier 

This is the Rate in the pound by which the rateable value is multiplied to give the annual rate bill for a property. The multiplier set annually by the National Assembly for Wales, and which is set at 0.452p for 2012/13, is the same for the whole of Wales. With the exception of a revaluation year, the multiplier cannot rise by more than the rate of increase in the retail price index.
