## Summary

The Home Office procured IT services to host, manage and support the Intelligence Driven Offender Management System (IDIOM). The requirement covers managed hosting, operating system management, application management and professional services, including working with the Home Office, Police Digital Services, service management teams and other suppliers to maintain the system’s operation and security. This is a technology support and managed services requirement, classified under IT services including consulting, software development, internet and support. Delivery is centred on the United Kingdom, with locations also listed across Europe, the Isle of Man, the Channel Islands, British Overseas Territories and the wider world.

The procurement is complete and was awarded through a selective call-off from a framework agreement. The tender submission deadline was 31 March 2026 at 5pm. The Home Office awarded the contract to Vodafone UK Limited on 11 June 2026 for £508,869.98 including the stated GBP currency. The awarded contract runs from 27 June 2026 to 26 June 2027. There was one award and one supplier. The procurement is for services and was marked as unsuitable for small and medium-sized enterprises and voluntary, community or social enterprises. The award covers hosting, management and support for IDIOM, including operating system and application management, professional services, and maintaining operational security with the Home Office and its delivery partners.

This award demonstrates demand from the Home Office for a specialist provider able to run and support a live offender management platform as part of a wider public-sector technology environment. A credible competitor for a future requirement would need proven managed hosting capability, strong operating system administration and application support, and the professional services capacity to resolve issues and maintain service continuity. Experience of security-sensitive systems, structured service management and collaboration with government technology bodies and incumbent suppliers would be important. The requirement was marked unsuitable for SMEs and VCSEs, indicating that scale, organisational capacity and the ability to support a nationally distributed service are likely to matter. Vodafone UK Limited, a large supplier, was selected.
