The procurement concerns the provision of application service management within the "Application service providers" category. This contract pertains to essential legacy applications under the Core Business Platform, located at 100 Parliament Street, Westminster, London. The modification entails enhanced support and maintenance services over a 5-year period, totalling £107,271,468, effective from 1st July 2025. The procurement process presently stands at the contract modification stage, aiming to address necessary service continuations and application modernisation. This procurement presents opportunities for businesses involved in IT support and development, particularly those with expertise in maintaining legacy systems and providing modernisation solutions. Companies offering application decommissioning, system integration, and strategic analyses can find growth potential through partnerships or by positioning themselves for similar future projects. Businesses that can navigate complex government IT infrastructures and demonstrate a capability for seamless transition and upgrade of critical systems would be well-suited to compete in this sphere. ## Notice The contract is for business application support and maintenance services for a set of business-critical legacy HMRC applications. The contract includes options to provide decommissioning and application modernisation services for the business applications in scope. The purpose is either to decommission services during the initial term of this contract or prepare enduring applications and services to go to market in future. The contract will have a duration of 3 - 5 years. ### Lot Information Lot 1 HMRC awarded a contract to Capgemini UK Ltd to provide Business Application, Support and Maintenance (BASM) services for a set of business-critical legacy HMRC applications which were part of the Core Business Platform. Prior to this Capgemini was the incumbent service provider to HMRC for these services (and other business applications, which were part of other replacement contracts or which are now decommissioned and no longer supported). The initial Prime Contract expired in June 2022. The services under the Core Business Platform are: Business Application Support and Maintenance (BASM) services; and optional business application development and enhancement services, system integration services; strategy, architecture and feasibility analysis services and decommissioning services related to the applications, which HMRC can use on a call off basis. The term of the Core Business Platforms contract is 5 years. The consumption of the services for the legacy applications under the contract was planned to decrease over the contract term as some services are decommissioned. The legacy applications supported by this contract are either (1) Being replaced and decommissioned or (2) Services which are aging and require some form of consolidation or modernisation in order to mitigate technical risks and prepare them for going to market in the future. This contract modification is to support these activities. The contract modification is PS107,271,468. ### Procurement Information The services required by HMRC consist of the provision of Business Application Support and Maintenance (BASM) services; and optional business application development services, system integration services; strategy, architecture and feasibility analysis services and decommissioning services to support business critical legacy HMRC applications. The applications in scope are either (1) services which are in the process of being replaced and will be decommissioned within the New Contract term or (2) services which are aging and require some form of consolidation or modernisation in order to mitigate technical risks and prepare for going to market in future. The applications generate substantial taxes and revenue for the UK and a number of the applications are classified as business critical and therefore must be wholly reliable. It is therefore imperative that the support of such applications continue to be delivered safely and without interruption. The award of the New Contract to Capgemini ensures the secure and continued support of the legacy applications whilst they are either decommissioned or undergo technical modernisation. HMRC's assessment is that support services for applications which only have a time-limited life before they are decommissioned can only be provided by Capgemini. This is due to the increased technical risks involved during the migration of services to a replacement application and the decommissioning of all elements of the legacy application that requires a considerable level of in-depth knowledge and experience of the solution, which only Capgemini have because of their 18 years of supporting those services. Due to the age and intricate interdependencies of the legacy applications which are deemed to require consolidation or modernisation, the support services for those applications, until they are modernised, can only be provided by Capgemini. These applications are a complex environment of small solutions which require extensive knowledge of HMRC's business processes to manage and some are also on aged technologies for which there is a reducing skills-base available. Modernisation is necessary to bring them to the required technical level and reduce inter-dependencies whilst preparing them for going to market in future. As these are business critical tax and benefit applications, HMRC requires the secure and uninterrupted delivery of support to those applications and considers the award of the New Contract to be the only option for securing delivery of those services until they are either replaced and decommissioned or have been brought to a suitable technical state via consolidation or modernisation. The resulting contract enables HMRC to deliver on its strategic priorities to protect live services and deliver contractual flexibility to manage decommissioning. In parallel, HMRC will be able to work with Capgemini to prepare enduring technologies and services to go to market. This is an award of a contract via the negotiated procedure without prior publication under Regulation 32 of the Public Contracts Regulations 2015. HMRC's view, having taken advice, is reliance on Regulation 32 is justified because services being procured under and for the term of the New Contract can only be provided by Capgemini because competition is absent for technical reasons. Accordingly, HMRC concluded that for technical reasons HMRC would procure services under the New Contract which only Capgemini could provide and for which there was no reasonable alternative. ## Key Details | Field | Value | | --- | --- | | Publication source | Find A Tender Service | | Latest notice | https://www.find-tender.service.gov.uk/Notice/043503-2025 | | Notice type | Award Notice | | Procurement type | Standard | | Procurement category | Services | | Procurement method | Limited | | Procurement method details | Award procedure without prior publication of a call for competition | | Tender suitability | Not specified | | Awardee scale | Large | | All stages | Award | ## Dates | Field | Value | | --- | --- | | Publication date | 28 Jul 2025 | | Submission deadline | Not specified | | Future notice date | Not specified | | Award date | 21 Mar 2022 | | Contract period | Not specified | | Recurrence | Not specified | ## Values | Field | Value | | --- | --- | | Tender value | Not specified | | Lots value | Not specified | | Awards value | Not specified | | Contracts value | £536,357,342 | ## Status | Field | Value | | --- | --- | | Tender status | Complete | | Lots status | Cancelled | | Awards status | Active | | Contracts status | Active | ## Buyer | Field | Value | | --- | --- | | Main buyer | HM REVENUE & CUSTOMS | | Additional buyers | H M REVENUE & CUSTOMS | | Locality | LONDON | | Post town | Central London | | Postcode | EC3R 6EE | | Country | England | | ITL 1 | TLI London | | ITL 2 | TLI3 Inner London - West | | ITL 3 | TLI35 Westminster and City of London | | Local authority | Westminster | | Electoral ward | St James's | | Westminster constituency | Cities of London and Westminster | | Delivery location | Not specified | ## Supplier | Field | Value | | --- | --- | | Number of suppliers | 1 | | Supplier names | CAPGEMINI | ## CPV Codes ### Divisions - 72 - IT services: consulting, software development, Internet and support ### Codes - 72250000 - System and support services - 72261000 - Software support services - 72262000 - Software development services - 72263000 - Software implementation services - 72416000 - Application service providers ## Release History - 28 Jul 2025 at 13:27 - AwardUpdate - Award Notice - https://www.find-tender.service.gov.uk/Notice/043503-2025 - 24 Mar 2022 at 16:27 - Award - Award Notice - https://www.find-tender.service.gov.uk/Notice/008052-2022 ## Notice URLs - http://www.gov.uk - http://www.hmrc.gov.uk ## Provenance This Markdown file is an alternate public rendering of the D3 Tenders contract record.
