Summary of the contracting process

HM Revenue & Customs procured IT service integration for its Data Warehouse Transformation programme. The appointed service integrator is responsible for coordinating, governing and assuring the delivery of multiple internal and external suppliers, ensuring collaboration and end-to-end service delivery across the programme ecosystem. This is a technology consulting and support service, within the wider IT services category (CPV 72000000), rather than a standalone software development or infrastructure supply contract. Delivery is across the United Kingdom. The requirement is for a single overarching integration function capable of working across a complex programme environment, aligning different suppliers, managing dependencies and providing assurance that services are delivered coherently against the transformation programme’s objectives. The buyer is HM Revenue & Customs.

The procurement has been awarded and the tender is complete. HM Revenue & Customs used a selective call-off from a framework agreement. The tender deadline was 20 March 2026 at 12:00 UTC. IBM United Kingdom Limited received the award on 1 June 2026 for £35 million. The contract period runs from 20 July 2026 to 30 June 2031. The requirement was evaluated as a service procurement for IT consulting, software development, internet and support, with the opportunity structured as Lot 1, Service Integrator. The award is active and the published outcome identifies IBM United Kingdom Limited as the selected supplier. The contract covers the full service-integration requirement for the Data Warehouse Transformation programme rather than separate awards for individual delivery components.

For suppliers assessing future HMRC opportunities, this award demonstrates demand for a large-scale service integration capability within a government data-transformation programme. A credible competitor would need to coordinate several internal and external suppliers, govern complex service relationships, manage dependencies across an ecosystem and assure end-to-end delivery. Relevant strength lies in programme-wide integration and assurance, not simply in providing software, hosting or individual technical specialists. The successful supplier profile is a large organisation able to operate at substantial scale, take accountability across multiple suppliers and maintain effective collaboration throughout a long-running transformation. Businesses with established public-sector delivery controls, strong governance, supplier-management capability and experience assuring complex IT services would be best placed to compete when a comparable requirement returns to market.
