How business rates are calculated
Your business rates bill is calculated by multiplying a Multiplier or Uniform Business Rate by your rateable value.
Central government sets the Multiplier. The Multiplier cannot rise by more than the rate of inflation unless it is a revaluation year.
In London there is also a business rate supplement to pay towards the Crossrail Project. It applies to premises with a rateable value in excess of £75,000. A multiplier of 0.02 is used to calculate the Business Rates Supplement in such instances.
