Post Office confirms exit timeline for Fujitsu contract

• Post Office has agreed dates for a summer handover process to end its long-running contract with Fujitsu.
• Accenture will assume the day-to-day running of the current Horizon system from Fujitsu whilst a new system is developed and installed throughout Post Office’s network of 11,500 branches.

Post Office, Accenture, and Fujitsu have agreed a handover process that will ensure continuity and operational stability for customers and postmasters whilst the Horizon system is transferred to Accenture from Fujitsu.

The three organisations have jointly agreed that Fujitsu will hand over the operation of Horizon to Accenture between 1 June and 1 September 2027. The final date will be confirmed in March 2027.

Post Office’s current contract with Fujitsu runs until March 2027. A short, time-limited contract extension has also been agreed to facilitate the transition process.

Post Office’s CEO Neil Brocklehurst announced in May 2026 that Accenture would be undertaking a ‘walk in and take over’ exercise for the current Horizon system, assuming day to day operations from Fujitsu, as well as developing the back-end of the new system to replace Horizon which will be used in branches.

Alongside Accenture, the new system will be developed in partnership with OneView Commerce and Escher. The suppliers bring international experience and best practice from other postal systems and will work closely with Post Office to introduce a simpler and more effective IT system throughout the branch network.

Post Office CEO Neil Brocklehurst said: “Ending our contract with Fujitsu is a critical milestone in Post Office’s transformation, and today’s agreement secures the transition away from Fujitsu and over to Accenture safely and responsibly to achieve our target of summer 2027.

"In addition to ending our contract with Fujitsu, we are also working at pace with our leading technology suppliers, Accenture, OneView Commerce and Escher, to build a modern, resilient platform able to make everyday life easier for customers and postmasters for years to come.”

Matt Prebble, Head of Accenture in the UK & Ireland, said: “We understand how important it is that postmasters can continue serving their customers and communities throughout this transformation. Our priority is a safe and carefully managed transition that supports continued trading in branches."

Sara Barlow, Post Office Non-Executive Director and Postmaster at Rainhill Post Office, said: “Replacing Horizon is one of the biggest changes the business has undertaken and an important milestone for the future of the network. Success isn't just about delivering technical capability, it is about ensuring new systems work well for postmasters and branch teams and help them serve customers effectively.

“For me, appointing the new suppliers felt like a genuine milestone. It represented an opportunity to learn from the past while building something better for the future. There is still a lot of work ahead, but it is encouraging to see the focus on getting this right.”

Horizon will be retired as part of Post Office's five-year transformation plan. Post Office’s transformation will see software and hardware throughout the historic institution upgraded to meet the needs of the modern customer with greater flexibility and convenience.

This agreement comes after the Chancellor announced investment for Post Office in his recent Budget, with upgrades planned for 600 Post Office branches and the rollout of up to 1,000 multi-carrier parcel Drop Boxes by the end of the financial year. Together with the new computer system, these improvements to branch technology will enable simpler transactions and more efficient services for Post Office customers.
