Summary of the contracting process

Transport for London, through Rail for London Infrastructure, is seeking maintenance and repair services for the Elizabeth line’s Tunnel Ventilation and Controls System on the central section. The work covers systems serving 21 km of twin-bore tunnels beneath central London. These systems manage the tunnel environment during normal operations and support emergency response, including smoke extraction and safe evacuation. They are integrated with fire detection and centrally operated through an automated control platform. The maintenance is intended to sustain the reliability and safety of this critical railway infrastructure and maintain continuity of service. The requirement is for specialist rail infrastructure and building management maintenance, rather than general railway operations or passenger services.

The buyer invited offers through a competitive flexible procedure, following market sounding and supplier selection stages. The process reached tender, with qualified suppliers invited to submit tender responses through TfL’s electronic tendering platform. Expressions of interest were due by 9 October 2026 at 17:00; enquiries were due by 2 October 2026 at 17:00. The contract is scheduled to run from 22 March 2027 to 21 March 2030, with an option to extend to 22 March 2032. The estimated value is £17.58 million excluding VAT (£21.68 million including VAT); the value was amended. There is one lot. Evaluation weights technical quality at 50%, commercial at 30%, health, safety, environment and quality at 10%, and responsible procurement/social value at 10%. The intended award date is 12 March 2027.

This requirement suits suppliers experienced in maintaining fixed tunnel ventilation systems and building management controls, particularly in a safety-critical railway environment. Capability relevant to the work includes maintaining automated control systems and their integration with fire detection, and supporting both routine environmental management and emergency functions such as smoke extraction and safe evacuation. Suppliers need the capacity to maintain equipment across the central Elizabeth line tunnels while supporting reliable railway operations. The buyer used the Rail Industry Supplier Qualification Scheme to identify suppliers in fixed ventilation maintenance and general building management service categories; participation in the relevant qualification stages formed part of supplier selection. Small and medium-sized businesses are considered suitable. The weighted assessment gives technical delivery the greatest importance, alongside commercial offer, health and safety, environmental and quality performance, and responsible procurement/social value.
