Revaluation 2026
Every three years the Valuation Office Agency (VOA) updates the rateable values of over 2 million commercial properties in England and Wales. This process reflects changes in the market and is known as a revaluation. The next revaluation will come into effect on 1 April 2026.
The Valuation Office Agency has published the draft list for the 2026 Revaluation.
You can check the draft rateable value of your property and get an estimate of what your business rates bill may be from 1 April 2026.
Business rates valuation
The Valuation Office Agency (VOA), an agency of His Majesty's Revenues and Customs, is responsible for calculating the rateable value of your property.
The rateable value broadly represents the yearly rent that the property could have been let for on the open market on a particular date. For the revaluation which came into effect on 1 April 2026, this date was set as 1 April 2024.
Every three years, all rateable values are reassessed by the VOA at a general revaluation to ensure that business rate bills reflect changes in the property market.
Local councils use the rateable value to calculate your business rates bill and are responsible for billing and collection of business rates, including any relief from payment.
How your rates are calculated
To understand why your property has a certain rateable value, read the VOA’s guidance on how your rates are calculated.
If you are concerned that your business rates may be incorrect, you can check and update your information using the VOA's Check and Challenge your business rates service.
With a VOA business rates valuation account, you can:
- check the details the VOA holds
- tell the VOA if something is wrong
- see how your property’s valuation was worked out

Transitional relief scheme
Transitional relief limits how much your bill can change each year as a result of business rates revaluation.
You’ll get transitional relief if your rates go up by more than a certain amount. This means changes to your bill are phased in gradually until it reaches the full amount set by a revaluation. Your bill will be adjusted automatically if you are eligible.
From 1 April 2026, a new transitional relief supplement will apply. This will be 1p for every £1 of your property’s rateable value. It will partially fund the 2026 transitional relief scheme.
