The London borough of Bexley and Capita Local Government Services have agreed to extend and expand their existing partnership.
Under a new contract, worth £14m, the deal will run for three years before the original expiry date of June 2016, and the council's financial assessment team will transfer to Capita Local Government Services.
The service will join council tax and business rates administration, cashiering services and benefits administration in the contract. The financial assessments team is responsible for the administration of applications for assistance towards residential care costs and costs for care packages delivered to citizens in their homes. There are currently just over 3,700 active assessment cases in Bexley.
