The “rateable value” of your property which is assessed by the Valuation Office Agency (VOA), (an agency of HM Revenue and Customs), is multiplied by the “multiplier” (set by central government).
Rateable value
A property's rateable value is an assessment of the annual rent the property would rent for if it were available to let on the open market at a fixed valuation date.
From 1 April 2023, the rateable values will be based on the valuation date of 1 April 2021.

Revaluation
The VOA regularly reassess and update the rateable values of all business properties usually every five years. This is called a Revaluation. This is done to maintain fairness in the system by redistributing the total amount payable in business rates, reflecting changes in the property market. Revaluation does not raise extra revenue overall. The current revaluation is effective from 1 April 2023, and the next revaluation will be on 1 April 2026.
Transitional relief limits how much your Business Rates bill can change each year as a result of revaluation.
Multiplier
There are two business rates multipliers: the standard multiplier and the small business multiplier. These are set by the government and are likely to change annually in line with inflation. However, for 2025/26 the small multiplier remains unchanged.
| Year | 2021/22 | 2022/23 | 2023/24 2024/25 2025/26 |
|---|---|---|---|
| Small Business Multiplier | 49.9p | 49.9p | 49.9p 49.9p 49.9p |
| 51.2p | 51.2p | 51.2p 54.6p 55.5p |
