Summary of the contracting process

Post Office Limited procured two UK-wide technology services lots to replace and modernise its Horizon estate. Lot 1 covers a replacement service provider to take over from Fujitsu Services, stabilise the service where required, and transform Horizon and related systems towards cloud-based technologies. Lot 2 covers a fully supplier-supported commercial off-the-shelf electronic point-of-sale system delivered as software as a service, with ongoing support, updates and optimisation; physical branch technology deployment is excluded. The work is primarily information systems, point-of-sale software, software-related support, consultancy, testing, backup and catalogue conversion services. The contracts support Post Office branch operations across the United Kingdom, with the possibility of separate suppliers or one supplier covering both lots.

The procurement used a competitive flexible procedure under the Procurement Act 2023 and is complete following evaluation and award. Lot 1 was awarded to Accenture (UK) Limited on 21 May 2026 for £269,000,000 excluding VAT (£322,800,000 including VAT). Its contract was signed on 4 June 2026 and runs from 4 June 2026 to 3 June 2031, with possible extensions up to 3 June 2033. Lot 2 was awarded to OneView Commerce, Inc. on 26 June 2026 for £141,000,000 excluding VAT (£169,200,000 including VAT). Its standstill period ends on 21 August 2026 and the scheduled signature is 22 August 2026; the contract period is 22 August 2026 to 27 June 2036, with possible extensions to 27 June 2038. Both lots used quality, commercial and social value criteria weighted 65%, 25% and 10%.

This procurement demonstrates demand for suppliers able to deliver business-critical retail technology at national scale, combining transition, service management, cloud transformation and high-volume operational support. A credible Lot 1 competitor would need experience taking over complex live services, stabilising and transforming legacy systems, integrating suppliers and managing delivery through work orders or additional service requests. Lot 2 capability centres on a configurable commercial off-the-shelf electronic point-of-sale platform delivered as SaaS, with secure hosting, implementation support, continuous updates, optimisation, data services and dependable customer support. Relevant suppliers should be able to demonstrate strong capacity, technical capability, economic standing and comparable experience, while meeting demanding service availability targets and delivering measurable social value, including carbon reduction. The requirement also involves managing dependencies with other technology providers and subcontractors.
