## Summary

Transport for London (TfL) is in the planning stage of a procurement process seeking a specialist support partner to provide ongoing technical support and expertise for a portfolio of legacy infrastructure technologies. The procurement, titled "Legacy Infrastructure Support," falls under the services industry category and encompasses various locations across the United Kingdom. As of the published date, 14th July 2026, TfL is gathering market input with a milestone set for 7th August 2026, marking a due date for engagement for interested parties. The procurement approach will involve understanding market capability and delivery methods for maintaining legacy systems such as Microsoft Windows Server, SQL Server, Oracle, Solaris, and Red Hat platforms. The procurement process focuses on operational support, incident management, risk management, and supports the eventual migration of services to modern platforms.

This procurement offers significant growth opportunities for businesses that specialise in IT infrastructure support, especially those with experience in dealing with legacy systems and unsupported technologies. Companies that can demonstrate robust operational processes and risk mitigation strategies will be well-positioned to compete. The engagement is particularly suitable for IT service providers that can offer both managed service and flexible consumption-based support models. The procurement highlights opportunities for innovation in supporting critical legacy infrastructure while ensuring cybersecurity compliance and regulatory adherence for TfL’s operations. Suppliers are encouraged to showcase their commercial flexibility and readiness to scale services as the legacy infrastructure evolves.

## Notice

Transport for London (TfL) is seeking a specialist support partner to provide 24x7x365 break-fix support and technical expertise for a portfolio of legacy infrastructure technologies that are no longer fully supported by their original vendors.

The requirement covers operational support, incident management, service desk provision, escalation management, reporting, cybersecurity compliance, risk management and support for the eventual migration of services to modern supported platforms. TfL requires a service that can scale as the legacy estate changes over time. Suppliers must demonstrate robust operational processes, the ability to mitigate risks associated with unsupported technologies, and commercial flexibility through both managed service and consumption-based support models.
