Revaluation 2026
The Valuation Office Agency (VOA) regularly updates the rateable values of all business and other non-domestic properties (properties that are not just private homes) in England and Wales. This is called a revaluation.
Rateable values are the amount of rent a property could have been let for on a set valuation date. For the 2026 valuation, that date was 1 April 2024. Your rateable value isn’t the same as the rent you are paying on your property.
We use these rateable values to calculate business rates bills.
Revaluations are carried out to reflect changes in the property market, which means that business rates bills are based on more up-to-date information.
The new valuation will come into effect from 1 April 2026.
The Draft 2026 List is now available from the VOA – see finding your rateable value below
Contacting the Valuation Office Agency
We are responsible for anything to do with your business rates bill. The VOA is responsible for the valuation of your property. You will therefore need to contact the VOA for all queries about your rateable value.
Finding your rateable value
You are able to see the draft 2026 rateable value and previous rateable values for your property through the VOA’s Find a Business Rates Valuation Service on GOV.UK. This service allows you to compare your property’s rateable value with similar properties in the area.
You can also get an estimate of what your future business rates bill might be from 1 April 2026. This gives you an indication of what your business rates bill might be and may not take into account any relief you might be eligible for.
You can find further information and help on all elements of the 2026 business rates revaluation from the VOA on GOV.UK
Your property details need changing or you think your rateable value is too high
While you can’t challenge your 2026 valuation until 1 April 2026, you can update the details the VOA has about changes to your property details (such as floor area sizes and parking). If you believe your rateable value is too high, you need a business rates valuation account.
The VOA may accept your changes and update the current and future valuations. Please note, you must continue to pay your business rates as normal until a decision has been made.
Any changes made to your current valuation could result in your rateable value going up or down. This may also affect your future valuation from 1 April 2026.
You have until 31 March 2026 to request any changes to your current rateable value using your business rates valuation account. After 1 April 2026 you will only be able to make changes to your new valuation.

Working with a business rates agent
You can manage your business rates yourself. If you want to appoint an agent, the VOA has published a guide about how to choose a business rates agent.
If you want to authorise an agent to act on your behalf, you can appoint one using a business rates valuation account.
