Business rate supplements

The Business Rate Supplements Act 2009 enables levying authorities – county councils, unitary district councils and, in London, the Greater London Authority - to levy a supplement on the business rate to support additional projects aimed at economic development of the area.

Business Rate Supplements (BRS) are not applicable to properties with a rateable value of £50,000 or below, and authorities have discretion to increase that threshold. The total maximum BRS which may be levied by a levying authority is 2p per pound of rateable value. Levying authorities have the power to apply such reliefs to the BRS as they think appropriate and in such cases must include an explanation of the rules for the application of those reliefs in the final prospectus for the BRS.

Crossrail Business Rate Supplement

The Greater London Authority (GLA) introduced a business rate supplement (BRS) on 1 April 2010 to finance £4.1 billion of the costs of the £14.5 billion Crossrail project.

What is Crossrail and how will it benefit your business?

Crossrail will connect the outer suburbs and Heathrow to the West End, City and Canary Wharf. It is pivotal to the future of London’s economy and the increased earnings – from new jobs and quicker journeys – will benefit businesses across London.

It is the single largest investment in London’s infrastructure for decades, employing up to 14,000 people at the peak of construction. Crossrail services are due to commence on the Shenfield to Liverpool Street section in 2017 and through central London in 2018 followed by a phased introduction of services on the rest of the route.

Developments in the construction and financing of Crossrail

The Mayor of London agreed a settlement with the Government in October 2010 for the Crossrail route and secured investment for the upgrade of the Tube. Crossrail is now under construction at key sites across London.

In April 2012 the Mayor introduced a community infrastucture planning (CIL) levy on new developments in London to finance Crossrail. This is paid for by the developer. Find at more at

How will London’s businesses help to fund Crossrail?

The Crossrail BRS will be used to finance £3.5 billion worth of GLA borrowing and the repayment of this sum after Crossrail is completed. A further £0.6 billion of BRS revenues will be used to finance the construction works directly. The Crossrail BRS will need to be levied until the GLA's borrowing is repaid which is expected to be some time in the 2030's.  

Does my business have to pay the Crossrail BRS?

Your rates bill makes clear if you are liable to pay the BRS. The Crossrail BRS is applied only to assessments (e.g. business and other non domestic premises) on the local rating lists of the 32 London boroughs and City of London Corporation with a rateable value of more than £55,000. Over 80 per cent of non domestic properties in London are therefore exempt.

How much do I pay if my property's rateable value is above £55,000?

The Crossrail BRS multiplier for 2015-16 is 2p per pound of rateable value. Reliefs for the Crossrail BRS will apply on the same basis and at the same percentage rate as for your National Non Domestic Rates (NNDR) bill, although no transitional relief is provided for the BRS.

Keeping you up to date

We will continue to provide an annual update for ratepayers over the lifetime of the BRS.
