How your business rates are worked out
Revaluation
Every three years, the government checks the rental values of business buildings in England and Wales. This is called revaluation. It's undertaken by the aluation Office Agency (VOA). Revaluation helps make sure businesses pay the right amount of tax based on current property prices. The next revaluation starts on 1 April 2026.
Rateable Value
A rateable value is an estimate of how much rent a building could cost each year. For the 2026 revaluation, they used prices from 1 April 2024. These values are used to work out business rates bills.
Why revaluations matter
Revaluation keeps things fair. It makes sure businesses pay tax based on up-to-date rental prices, not old ones.
Contacting the VOA
We send your business rates bill, but the VOA works out the value of your property. If you have questions about your rateable value, contact the VOA.
You can use the VOA’s online services to:
- Find your business rates valuation
- Update property details like floor size or parking (you’ll need a business rates valuation account to sign in or register)
- Challenge your rateable value if you think it’s too high – but keep paying your bill until they make a decision
