Business rates and how they are calculated
We calculate how much you have to pay by applying a rating multiplier to your rateable value and deducting any relief to produce your final bill.
The rateable value (set by the Valuation Office Agency) is normally based on the open market annual rent for your property. This figure is likely to be different to the rent you pay as it is a fixed valuation taken from a set date and open to government assumptions.
Rateable values are assessed by the Valuation Office Agency and published on their website. The current 2017 is based on rental values at 1 April 2015.
The next revaluation is due in 2021.
The rating multiplier is set annually by central government and cannot be raised by more than the increase in the retail price index, except in a revaluation year.
For 2019/20 multiplier rates are:
- 50.4p, national non-domestic rate multiplier (2018/19 rate – 49.3p)
- 49.1p, small business multiplier (2018/19 rate – 48.0p)
The small business multiplier is used for occupied properties with a rateable value of less than £15,000.
