This is only an estimate. We always recommend a full liability review to ensure your business rates are assessed correctly and to identify any potential opportunities for savings.

A business rates calculator is an online tool that provides an estimate of the business rates payable for a commercial property.
It uses information such as the property’s rateable value and the relevant business rates multiplier. Where applicable, it may also take account of selected reliefs or adjustments.
Yes. The Dunlop Heywood Business Rates Calculator is free to use and provides an instant estimate based on the information you enter.
There is no obligation to instruct Dunlop Heywood after using the calculator. However, our specialist business rates team is available if you would like help understanding the result or checking your bill.
The basic calculation is:
Rateable Value × Business Rates Multiplier = Estimated Annual Business Rates Liability
Reliefs, transitional arrangements, occupation dates and other adjustments may then affect the final amount payable.
The calculator will ask for the information needed to produce an estimate. This may include:
For the most useful result, check that the information entered matches your current business rates bill and property circumstances.
The rateable value is an estimate of the annual rent that a commercial property could have achieved on the open market at a specified valuation date.
It is not necessarily the same as the rent you currently pay or the market value of the property. It is the figure used as the starting point for calculating business rates.
Your rateable value should be shown on your business rates bill.
For properties in England and Wales, you can also use the Government’s online business rates valuation service to find the rateable value and check how it has been calculated.
The business rates multiplier is the figure applied to a property’s rateable value to calculate its basic annual liability.
Multipliers are set for each financial year and can vary according to the property’s location, rateable value and, in some circumstances, the type of business occupying it.
The calculator is designed to provide a useful estimate for many straightforward scenarios. It is not a definitive calculation of the amount that should appear on your bill.
Business rates are complex, and the final liability can be affected by reliefs, transitional arrangements, occupation dates, historic adjustments and property-specific circumstances.
A difference does not automatically mean the bill is incorrect. It may, however, indicate that the figures deserve closer examination.
The calculator can only take account of the reliefs covered by the tool and the information you enter.
Eligibility for relief can depend on the property, the ratepayer, the type of business and the relevant dates. A detailed review may therefore be required to confirm whether a relief applies and how it should affect the bill.
You may be able to use the calculator to obtain an initial indication, but empty property rates can be particularly complex.
The liability may depend on when the property became empty, the type of premises, any exemption period and whether another exemption or relief applies. Speak to our team if you require advice about an empty property.
Business rates systems, multipliers and reliefs differ across England, Wales, Scotland and Northern Ireland.
Check the guidance provided with the calculator to confirm the locations and financial years it covers. Dunlop Heywood provides specialist business rates advice across the UK if your property or circumstances are not covered by the online calculation.
Yes. You can calculate an estimate separately for each property covered by the tool.
For a large or complex portfolio, a property-by-property calculation may not identify wider issues such as inconsistent liability dates, missing credits, changes in occupation or different relief treatments. Dunlop Heywood can undertake a structured review across an entire portfolio.
First, check that you have entered the correct rateable value, financial year, property information and relief details.
If the figures still differ, review the bill for dated adjustments, reliefs and other charges. A lower estimate does not prove that you are being overcharged, but it can provide a useful reason to request a detailed business rates audit.
No. Using the calculator does not change your rateable value, amend your bill or begin a formal challenge.
If there are grounds to question the assessment or liability, the appropriate next step will depend on the property and the reason for the difference. Dunlop Heywood can review the position and advise whether further action may be appropriate.
A review can provide reassurance that the charge is understood and identify any areas that require further investigation.
Yes. Dunlop Heywood provides specialist business rates advice to owners and occupiers across the public and private sectors.
Our team can undertake a detailed audit of the bill, rating assessment and relevant property circumstances. This provides a more comprehensive review than an online estimate alone.
The calculator provides the estimate. Dunlop Heywood provides the complete picture.
