## Summary

The Post Office Limited, headquartered in London, is currently in the award stage of its procurement process for a "1 Year Extension of the Horizon Services Agreement". The tender, initiated in November 2025, falls under the IT services category, encompassing consulting, software development, Internet, and support. It specifically maintains and develops Point of Sale/Service systems across multiple channels while addressing several vital contract terms such as governance enhancements and legacy system upgrades. The agreement extends for another year starting 1 April 2026, ending on 31 March 2027. The regions covered include UKJ, UKK, and UKN, with Fujitsu Services Limited, located in Bracknell, acting as the main supplier. Contract work is valued at £2,479,000,000, with Fujitsu particularly chosen due to technical reasons that prevent moving to another supplier given Horizon's complexity and age.

This contract extension presents significant growth opportunities for IT service providers familiar with legacy systems and complex infrastructures. Companies with expertise in software maintenance, development, and support for critical and extensive service agreements would find this tender highly suitable. The project provides ample scope for businesses that can offer tailored solutions to enhance governance structures, maintain complex systems, and manage end-of-life service components. Suppliers who can accommodate the specific interoperability needs and navigate the intricacies of large-scale IT operations in government-linked services are best positioned to compete. Furthermore, firms adept at handling transition periods and technical upgrades can play a pivotal role in extending and updating such legacy service contracts.

### Lot Information

Lot 1

Continuing provision of application and service management, maintenance, development and support services under an existing software and IT services agreement relating to Point of Sale/Service ('POS') customer facing transactions across multiple channels. Other than the extension of the term of the agreement, all other terms and conditions shall remain the same with the exception of FSL obligations in respect of: End of Service Life (EOSL) Impact and Relief Principles, improved Governance for better management, Removal of Redundant Clauses and Schedules, maintenance of software that resides on HNG-X system and licenses required, from the date of the execution of the modification; and NB: Any investment will be subject to POL agreeing suitable work orders with FSL.

Options: Option to extend for a further 12 month term.

### Procurement Information

This Notice relates to the modification of an existing contract that has been necessary due to the following reasons. The Authority's existing Horizon system is a highly complex, legacy platform, written in outdated versions of software languages, and incorporates five 'systems' in one i.e. financial services, banking, government services, mails, and retail. "Horizon" is an aging platform, has an inflexible monolithic architecture that makes technology change difficult. It was not designed for multi-channel digital operations. The services cannot for economic and technical reasons be provided by a contractor other than the original contractor before the expiry of the Horizon Agreement because of the specific interoperability requirements and the highly complex nature of the existing infrastructure and the Authority's business model and operating procedures. A change of contractor would result in disproportionate technical difficulties in implementation as well as operation and maintenance. Awarding the contract to a different contractor would also cause significant inconvenience in terms of service delivery, reliability, and continuity of service, not least because of risk of incomplete transfer of know-how. Changing the original contractor would result in a number of sunk costs, including an increase in run costs, dual running costs, and additional exit/transition costs for a 2-year service term. There would also be significant service risk as a result of engaging in two transitions of service provider within the relatively short time period of 2-3 years whereas an extension with the original contractor would just require one such transition. In summary, a change of contractor cannot be made for technical or economic reasons and would cause substantial inconvenience and duplication of costs for the Authority in accordance with Regulation 72(1)(b) of the Public Contracts Regulations 2015. The increase in price as a result of the modified contract is less than 50 % of the original contract value.
