National Non-Domestic Rating Multiplier
The local authority works out the business rates bill for a property by multiplying the rateable value of the property by the appropriate non-domestic multiplier. There are two multipliers: the standard non-domestic rating multiplier and the small business nondomestic rating multiplier. The Government sets the multipliers for each financial year, except in the City of London where special arrangements apply.
Ratepayers who occupy a property with a rateable value which does not exceed £50,999 (and who are neither entitled to certain other mandatory relief[s] nor liable for unoccupied property rates) will have their bills calculated using the lower small business non-domestic rating multiplier, rather than the standard non-domestic rating multiplier. Both multipliers for a financial year are based on the previous year's multiplier adjusted to reflect the Consumer Price Index (CPI) inflation figure for the September prior to the billing year, unless a lower multiplier is set by the government. The current multipliers are shown on the front of your bill.
