Rateable value and revaluations

Business rates 2026 revaluation

Every 3 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 most recent revaluation will come into effect on 1 April 2026.

Rateable values are the amount of rent a property could have been let for on a set valuation date. For the 2026 revaluation, that date is 1 April 2024. Your rateable value is not the same as the rent you are paying on your property.

Haringey use the rateable value assigned by the Valuation Office Agency to calculate your business rates bill.

At a revaluation, business rates bills may increase, decrease or stay the same. A rise in your rateable value does not necessarily mean your business rates bill will increase by a similar amount.

What to do if you think your valuation is incorrect

While you cannot challenge your 2026 valuation until 1 April 2026, you can update the details the VOA has about your property or tell them if you think your valuation is wrong.

You do this by raising a Check against your current valuation using your business rates valuation account.

You have until 31 March 2026 to request any changes to your 2023 rateable value using your business rates valuation account. After 1 April 2026 you will only be able to make changes to your new valuation.

Transitional arrangements

The transitional relief scheme limits changes in rate bills as a result of the 2026 revaluation. Under the transitional scheme, limits continue to apply to yearly increases until the full amount is due (rateable value times the appropriate multiplier).

The scheme applies only to the bill based on a property at the time of the revaluation. If there are any changes to the property after 1 April 2026, transitional arrangements will not normally apply to the part of a bill that relates to any increase in rateable value due to those changes.

Changes to your bill as a result of other reasons (such as changes to the amount of small business rate relief) are not covered by the transitional arrangements.

The transitional arrangements are applied automatically and are shown on the front of your business rates bill.
