## Summary

West Sussex County Council procured a social care case management system, identified as Mosaic, to support its social care case management activities. The requirement is for services centred on an industry-specific software package, including the provision of the Mosaic system and associated service delivery. The work is for the council in West Sussex, with the buyer based in Chichester and delivery associated with the Chichester area and the wider South East of England. This is a specialist public-sector technology requirement rather than general IT supply: relevant businesses are software providers and service partners with experience delivering systems for social care organisations and public authorities.

The procurement has been completed and awarded following a selective call-off from a framework agreement. The award was made to ACCESS UK LTD on 21 August 2026 for £5,694,727.60 including the stated currency of GBP. The resulting contract runs from 28 August 2026 to 27 August 2030. The procurement’s estimated value was £4,745,606.33, and the tender submission deadline was 14 August 2026 at 12:00. The award covered one requirement rather than separately described lots. Evaluation was conducted through the framework call-off route. The opportunity was not identified as suitable for small or medium-sized enterprises or voluntary, community and social enterprises.

This award demonstrates sustained demand from West Sussex County Council for a substantial, specialist social care case management technology service. A credible competitor for a future requirement would need a mature case management platform designed for social care, with the functionality, security and reliability expected in a public-sector operating environment. It would also need the capacity to support a large council-wide deployment, provide implementation and ongoing service support, and demonstrate experience supplying comparable authorities. The procurement route shows that framework access and the ability to compete effectively through a structured call-off are commercially important. The selected supplier’s scale indicates that substantial delivery capability and organisational resilience are likely to matter.
