## Summary

HM Revenue & Customs commissioned IT services to migrate and decommission its legacy data warehouses. The work covers the safe transition of data, services and users to HMRC’s future DWIT architecture, with the aim of minimising disruption to the business. The appointed service must work alongside HMRC’s Service Integrator, Lakehouse and Feed Factory suppliers, so effective collaboration across a complex technology environment is central to delivery. This is a UK-wide requirement for specialist data and technology services, classified under CPV 72000000. The buying organisation is HM Revenue & Customs, based in London. The requirement is primarily a managed technology transformation service rather than the supply of software, hardware or routine IT support.

The procurement has been awarded and the tender is complete. HM Revenue & Customs used a selective procedure to make a call-off from a framework agreement. The tender submission deadline was 20 March 2026 at noon. The contract was awarded to Capgemini UK PLC on 1 June 2026, for £200,000,000. The contract period runs from 20 July 2026 to 19 July 2031. The award is active, and the contract notice records a signed-contract document. The opportunity was assessed as unsuitable for small and medium-sized enterprises and voluntary, community or social enterprises. This was a single requirement titled DWIT – Lot 2 Legacy Data Warehouses, covering the migration and decommissioning service described above.

This procurement demonstrates substantial, sustained demand from HMRC for specialist legacy data-platform transition services. A credible future competitor would need proven capability in migrating data warehouses, decommissioning inherited platforms and moving users and services into a new architecture without materially disrupting business operations. It would also need the capacity to coordinate delivery with a Service Integrator and specialist Lakehouse and Feed Factory suppliers, rather than operate in isolation. Experience of complex public-sector technology environments, disciplined transition planning, service continuity and controlled technical change would strengthen a supplier’s position. The requirement favoured established, large-scale providers able to manage a significant, collaborative transformation programme.

## Notice
