The HMRC Valuation Office updates rateable values every three years. 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.
The next revaluation will come into effect on the Sunday 1 April 2029.
Contacting the HMRC Valuation Office
We are responsible for anything to do with your business rates bill. The HMRC Valuation Office is responsible for the valuation of your property.
For all queries about your rateable value, you will need to contact the HMRC Valuation Office, and create a Business Rates Valuation Account on GOV.UK.
Find your rateable value
To find the rateable vale of your property, or similar properties or check how the rateable value of your property was calculated, this can be done using the GOV.UK website.
Your property details need changing
To tell the HMRC Valuation Office about changes to your property details (such as floor area sizes and parking) you need a business rates valuation account. The HMRC Valuation Office may accept your changes and update the current and future valuations.
Report a change to the Valuation Office
If you want to report a change to your property (such as floor area sizes and parking) or challenge its rateable value, contact the Valuation Office using your Business Rates valuation account.
Whilst your application is being processed, you must continue to pay your business rates as demanded until a decision has been made.
Business Rating Agents
Ratepayers do not have to be represented in discussions about their rateable value or their rates bill. Appeals against rateable values can be made free of charge. Ratepayers who do wish to be represented should be aware that members of the Royal Institution of Chartered Surveyors and the Institute of Revenues, Rating and Valuation are qualified and are regulated by rules of professional conduct designed to protect the public from misconduct.
Before you employ a rating adviser, you should check that they have the necessary -
- knowledge
- expertise
- appropriate indemnity insurance
Take great care, and, if necessary, seek further advice before entering into any contract.
The HMRC Valuation Office have published a guide on the GOV.UK website to inform customers on factors to consider when choosing a business rates agent.
