This document is a case study detailing the partnership between Hounslow Council and Liberata for a Business Rates Review Service. The objective of the review was to ensure that local businesses in Hounslow were correctly rated for Business Rates. Liberata offered a fully managed service that included canvassing, outbound calling, customer support, and administration from the Valuation Office Agency (VOA) on a 'risk and reward' basis, meaning no fees applied if the review was unsuccessful. The service began in 2019 and has resulted in significant financial benefits, including an additional rateable value of £4,288,250. The review identified 227 new prospects, of which 104 were not previously rated. This case study outlines the need for the review, as some businesses had not been revalued and others had not been rated at all. The partnership aimed to ensure fair taxation for all businesses across the borough.
