UK Business Rates: How They Work, What You Might Be Overpaying, and How to Challenge

How business rates are calculated#

Business rates are a property tax on non-domestic premises. Your annual rates bill = Rateable Value × Multiplier. The Rateable Value (RV) is an estimate of the annual market rent for the property, set by the Valuation Office Agency (VOA) based on a specific valuation date. The current valuations use 1 April 2021 as the relevant date. The multiplier is set annually by central government — for 2024-25, the standard multiplier is 54.6p per pound of rateable value, with a small business multiplier of 49.9p. A property with an RV of £30,000 faces a base rates bill of approximately £16,380 at the standard multiplier before any reliefs.

Small Business Rates Relief: full elimination for smaller properties#

Small Business Rates Relief (SBRR) eliminates or reduces rates for qualifying smaller businesses. If your property has an RV of £12,000 or less and it is your only business property, you pay zero rates — 100% SBRR. If the RV is between £12,000 and £15,000, you receive tapered relief. If you occupy multiple properties, the relief only applies to your main property and the rules become more complex. Apply to your local council for SBRR — it is not always applied automatically. If you are paying rates on a property with an RV below £12,000 and have not claimed SBRR, you may be due a refund for up to 3 years of overpayment.

Other reliefs that reduce your rates bill#

Retail, Hospitality and Leisure Relief: the government provides annual Retail, Hospitality and Leisure (RHL) relief for eligible properties — check the current relief percentage as it changes each financial year. Charitable relief: registered charities pay only 20% of their rates bill. Rural rate relief: 50-100% relief for specific property types in eligible rural areas. Empty property relief: properties empty for up to 3 months (6 months for industrial property) pay zero rates. Renewable energy exemptions: some renewable energy installations are exempt. Check with your local council which reliefs apply to your specific property and circumstances.

Challenging your rateable value#

If you believe your rateable value is set too high, you can challenge it through the Check, Challenge, Appeal (CCA) process administered by the VOA. Step 1 — Check: review the property details the VOA holds (floor area, property description, lease information) and report any factual inaccuracies. Corrections to factual errors may reduce your valuation without needing to proceed further. Step 2 — Challenge: if you believe the valuation methodology is wrong, submit a formal Challenge setting out the evidence for a lower valuation — comparable rental evidence for similar properties, market evidence of what the property would actually rent for. Step 3 — Appeal: if the Challenge is unsuccessful, appeal to the independent Valuation Tribunal. Many property advisers specialise in rates reductions and work on a contingent basis.

Managing your rates as part of property decisions#

Business rates should be factored into any commercial property decision. Before signing a lease on new premises, check the rateable value and calculate the expected rates bill. Ask the landlord whether the previous tenant received any rates reliefs that may not transfer to you. Understand the break clause and void period arrangements — you may inherit a rates liability for empty periods. For businesses considering downsizing, calculate whether a smaller property's SBRR eligibility would eliminate the rates bill entirely — which can significantly offset the disruption cost of moving.
