Cheshire Police Authority has signed a framework agreement with Capgemini for IT services to support back-office policing activities.
The framework will include technology to enable shared services. It is expected to generate savings of £40m for Cheshire Constabulary over ten years.
It will cover payroll systems, duty management, finance, procurement, performance management, logistics, asset management and fleet management systems.
Margaret Ollerenshaw, chairman of Cheshire Police Authority, said: 'We are clear that very substantial cost savings can be made in our back-office support functions which will help minimise the risk to our front-line services."
The framework agreement has been developed in collaboration with the National Policing Improvement Agency and will be made available for other police forces. It will run for four years, with specific services contracted under the agreement available for up to ten years.
