## Summary

HM Revenue & Customs commissioned IT consulting, software development, internet and support services for the design and technical assurance of a Clean Room and Hackathon supporting the re-procurement of the National Insurance and PAYE Service (NPS). The work covers cloud delivery and assurance for this procurement activity, requiring suppliers to help create a controlled environment for collaboration, testing and technical evaluation. Delivery is across the United Kingdom. This is a services contract led by HMRC, with the requirement suitable for small and medium-sized enterprises. The appointed supplier is Posterity Milestone Consortium, an SME. The work is therefore relevant to technology consultancies, cloud delivery specialists, technical assurance providers and organisations experienced in supporting major public-sector digital service procurements.

The procurement has been completed and awarded through a selective call-off from a framework agreement. HMRC awarded the contract to Posterity Milestone Consortium on 2 September 2026 for £500,000. The contract runs from 3 September 2026 to 25 March 2027. The tender submission deadline was 14 August 2026. The requirement was evaluated through the framework call-off process for the design and assurance of the NPS Clean Room and Hackathon, including cloud delivery and technical assurance. The award is active and the contract period has begun. This is a single service requirement rather than a set of separately described lots, with the stated procurement category covering IT and related technical support services.

This award indicates demand from HMRC for specialist support around cloud delivery, technical assurance and controlled collaborative environments used in major digital service re-procurement. Competitors seeking similar HMRC work would need to combine cloud engineering with independent technical assurance, software and internet support, and the ability to design and operate a Clean Room and Hackathon. Credibility would also depend on understanding complex public-sector technology programmes, supporting structured testing and evaluation, and working with stakeholders involved in replacing or re-procuring critical services such as National Insurance and PAYE systems. The opportunity demonstrates that an SME consortium can satisfy this type of requirement, so smaller specialist firms with complementary delivery and assurance capabilities may be well placed to form a credible team.
