Non domestic rates

Non-Domestic Rates, or business rates, collected by local authorities are the way that those who occupy non-domestic property contribute towards the cost of local services.

Crossrail business rates supplement (BRS)

Your rates bill will make it clear if you are liable to pay the BRS. The Crossrail BRS is applied only to assessments (for example business and other non-domestic premises) with a rateable value of over £75,000 on the local rating lists of the 32 London boroughs and City of London Corporation.

Revaluation 2023

The Valuation Office Agency (VOA)has updated the rateable values of all non-domestic properties with effect from 1 April 2023. These broadly represent the open market annual rental value a property could have been let for on 1 April 2021. The next revaluation will come into effect from 1 April 2026.

The VOA may change the rateable value if the circumstances of the property have changed. The ratepayer (and certain others who have an interest in the property) can also challenge the value shown in the list if they think it's wrong.
