How your rates are calculated
You can find full information and estimate your business rates on the GOV.UK website.
Challenge your rateable value
If you think it's wrong, you can challenge the rateable value of your business property by using the Valuation Office Agency service.
Private agents may help you challenge your rateable value, but won't always be successful and your bill could increase.
If you make a challenge, you'll still have to pay your usual business rates instalments while you wait for a decision.
