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 national non-domestic rating multiplier and the small business non-domestic 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 not entitled to certain other mandatory relief[s] or are liable for unoccupied property rates) will have their bills calculated using the lower small business non-domestic rating multiplier, rather than the national non-domestic rating multiplier.
The multiplier for a financial year is 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.
The current multipliers are shown on the front of your bill.
