## Summary

The procurement process for the RDG AWS Gateway & API development and support and maintenance services involves Rail Settlement Plan Limited as the buying organisation, based in London. The contract, categorised under "Industry specific software development services," is in the award stage, with the pending award notice dated 27th April 2026. The procurement method employed is a direct award, aimed at maintaining continuity in service provision due to technical compatibility considerations. The project value exceeds the public contracts threshold, necessitating transparency in the procurement process. The standstill period ends on 7th May 2026, with the contract commencing on 15th May 2026 and concluding on 14th April 2027, allowing for minor modifications as required. This process illustrates compliance with the convertible contract regulations under PA23.

This tender presents significant opportunities for businesses specialising in AWS Gateway operations and API development services. The direct award process emphasises the importance of existing provider expertise, offering scope for small and medium-sized enterprises (SMEs) with proven capabilities in cloud-based integrations and platform migrations. As the project is embedded within the RDG's operational infrastructure, companies with robust technical profiles and experience in managing complex software ecosystems are particularly suited to compete in upcoming procurements associated with this project. Future procurements in FY 26-27 will open additional opportunities, enabling further participation in the extension and development of this critical service framework.

## Notice

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
