Summary of the contracting process

Network Rail Infrastructure Limited is currently in the tender stage of procuring "Southern Region Passive Thermal Management Solutions for Legacy Lineside Signalling Equipment Housings (Location Cases)." This procurement process aims to address the increasing thermal stress experienced by legacy lineside equipment housings due to changing climate conditions. The solutions sought should be passive, avoiding active cooling systems due to operational constraints, and retrofittable without compromising safety. With a budget of £14,000,000, the project is located in London and the Southern Region of the United Kingdom, specifically targeting goods within the cooling and ventilation equipment category. The competitive flexible procedure allows for early down-selection of suppliers through a Procurement Specific Questionnaire (PSQ) stage with an expression of interest deadline set for 12 December 2025.

This procurement offers substantial opportunities for businesses specialising in innovative cooling and thermal management solutions. Small and medium-sized enterprises (SMEs) and voluntary, community, and social enterprises (VCSEs) are encouraged to participate. Successful bidders will have a chance to contribute to critical infrastructure maintenance, making over 15,000 retrofits in the Southern Region and potentially more nationwide. With the framework agreement supporting both competitive and direct award processes, firms with relevant experience and capability stand to benefit from long-term contracts starting in July 2026, fostering sustainable growth and operational expansion in the utility sector.

Notice Title

Southern Region Passive Thermal Management Solutions for Legacy Lineside Signalling Equipment Housings (Location Cases)

Notice Description

Legacy lineside equipment housings (dating from the 1960s-2000s) on the GB rail network are experiencing increasing thermal stress due to hotter, longer summers and changing climate patterns. These housings were not designed for elevated ambient temperatures or prolonged thermal loads and are increasingly at risk of overheating, which may degrade the reliability or lifespan of the sensitive signalling and telecoms equipment inside. In Kent Route, there are over 5,000 and in Southern Region there are over 15,000 of these housings (also known as Location Cases), and nationally over 60,000. Network Rail is seeking passive thermal management solutions that can be retrofitted to existing housings without compromising security, structural integrity, or existing cable penetrations. Active cooling systems are not desirable due to power constraints, maintenance burden, and whole-life cost implications.

Lot Information
