Employing a rating agent
You can query your rateable value by contacting your assessor. There's no charge for any information they provide.
You may want to use a rating agent to help you deal with issues such as appealing your rateable value or checking what the likely effect of any changes will be.
Before appointing a rating agent, make sure that you have a clear agreement on what they will do for you and what they will charge. Typically, tasks include valuing your premises to determine what the rateable value should be.
If there are grounds for a reduction, your agent can lodge an appeal and act as the point of contact with your local assessor. Remember that a reduction in your rateable value does not guarantee a reduction in your non-domestic rates bill.
Your agreement should clearly state what fees are payable to the agent and if these are affected if your rates bill isn't reduced.
Members of the Royal Institution of Chartered Surveyors (RICS) or the Institute of Revenues, Rating and Valuation (IRRV) must follow a rating consultancy code of practice. You can also get a free 30 minute consultation with a local rating surveyor by calling the RICS Enquiry Line on 0870 333 1600.
