Business rates valuation

Your premises will be given a rateable value by the Valuation Office Agency (VOA) which the Council will use to calculate how much rates you will pay.

The rateable value is then multiplied by a figure set annually by the Welsh Government (known as the multiplier) to calculate the rates payable.

Can the rateable value change?

The VOA may change the value if they think that there has been a significant change to the property, for instance if there has been an extension to the building, or if the property has been split or merged.

In some cases, the business rates payer (and certain others, including the Council, who have an interest in the property) may also ask for the rateable value of the property to be reviewed.

If the ratepayer and the VOA cannot agree upon the proposed rateable value, the matter will be referred to the Valuation Tribunal.

Can I appeal against my property’s valuation?

The Valuation Office Agency (VOA) values all business properties for business rates.  The valuation is based on information the VOA holds about your property. You can view and update this information at

If you appeal against your rateable value, you must still pay the rates shown on your rates bill until the result of your appeal is determined.

You can contact the VOA at If you are unable to use the online service you can also contact the VOA on 03000 505 505.
