How we calculate business rates
Rateable value
Each non-domestic property has a rateable value set by the valuation officers of the Valuation Office Agency (VOA). This doesn't include properties exempt from business rates.
The agency draws up and maintains a full list of all rateable values, which you can view on the GOV.UK website.
The rateable value of your property will be shown on the front of your bill. This figure broadly represents the yearly rent the property could have been let for on the open market on a particular date.
National non-domestic rating multiplier
We work out your business rates bill by multiplying:
- the rateable value of the property, with
- the business rates multiplier, which central government sets yearly in England on 1 April. This is normally changed each year in line with inflation.
Revaluations will now be held every 3 years. The latest revaluation came into effect on 1 April 2023.

For 2025/26:
- the national non-domestic multiplier is 0.555
- the small business non-domestic multiplier is 0.499
The small business multiplier applies to properties where the rateable value is less than £51,000.
