Summary of the contracting process

Rail Settlement Plan Limited bought AWS Gateway and API development, support and maintenance services for its rail industry technology environment. The work covers industry-specific software development associated with the AWS Gateway, including maintaining and extending the platform and managing the APIs that support it. The services are embedded in the migration of Rail Delivery Group’s MuleSoft platform services to Amazon Web Services, so the requirement concerns specialist cloud, API and integration capability rather than general IT support. Rail Settlement Plan Limited is the public-sector utility buyer, based in London, and the services relate to its UK rail settlement and delivery operations. The requirement was treated as a single service package and was identified as suitable for small and medium-sized enterprises.

The procurement is complete and was awarded through a direct award to Theodo Limited. The award was made on 24 April 2026, with a standstill period ending on 7 May 2026; the contract was signed on 14 May 2026. The contract runs from 15 May 2026 to 14 April 2027 and has a gross value of £1.8 million including applicable taxes. It is above the relevant public contracts threshold and is classified as a utilities procurement. The direct award was justified because Theodo’s existing services are embedded in the AWS migration, and changing supplier would create incompatible services and disproportionate technical difficulties in operation or maintenance, with a significant impact on a time-sensitive project. Minor modifications may be required during delivery. The selected supplier is Theodo Limited.

This procurement shows demand for suppliers able to develop and maintain AWS Gateway platforms and the APIs connected to them in a live, technically integrated rail environment. A credible competitor for comparable work would need strong AWS architecture and engineering capability, API development and lifecycle management expertise, and experience supporting integrations during a major platform migration. It would also need the capacity to provide dependable maintenance while introducing new platform requirements, without disrupting operational services. Experience with MuleSoft-to-AWS migration, complex enterprise integration and time-sensitive delivery would be particularly relevant, because continuity and compatibility were central to the buyer’s justification for retaining its existing supplier. The requirement was considered suitable for SMEs, indicating that a specialist technology business with the necessary technical depth and delivery capacity could be well placed when similar services are competed.

Notice Information

Notice Title

RDG AWS Gateway & API development and support and maintenance services

Notice Description

This is a Direct Award for AWS Gateway & API development and support and maintenance services that have been embedded in the project from its outset. The value of the spend has gone above the public contracts threshold and therefore has become a convertible contract under PA23. As Rail Settlement Plan Limited is a utility with no requirement to publish procurement notices for below threshold procurement awards, which this award originally started as, there is no original procurement notice to link this award to and comply with the convertible contract concept. Therefore, we are publishing Transparency and Contract Award notices to demonstrate that we are being fair and transparent to the market.

Procurement Information

The direct award to Theodo Limited complying with the convertible contract concept, concerns the supply of services by the existing supplier which are intended as an extension to services based on the circumstances where a change in supplier would result in the contracting authority receiving services that are different from, and incompatible with, the existing services, and the difference or incompatibility would result in disproportionate technical difficulties in operation or maintenance. The AWS Gateway & API development and support and maintenance services have been embedded in the delivery of migrating all of RDG's Mulesoft platform services into the AWS platform. To move away from Theodo at this point in the project would have a significant negative impact on time sensitive project. RDG is looking to run two procurements in the coming months for these services. The first will be for a supplier to maintain RDG's AWS Gateway, including any new requirements to the platform, and the second procurement will be for a Dynamic Marketplace for the provision / development of API's and the support and maintenance associated with managing these APIs. Both these procurements shall run in FY 26-27. This award intends to ensure compliancy with PA23 for any additional spend with Theodo Limited until the new contracts are in place that will be procured in compliance with an above public contracts threshold procurement process legislation. The spend figure incorporates spend from the first agreement with the supplier from 24th Feb 2025 (inception of PA23) and spend expcted until the procurement is completed early 2027
