## Summary

First Great Western Limited is procuring specialist services to repair, refurbish, overhaul and technically support HVAC components used across its rolling stock fleet. The work includes fault diagnosis, testing, replacement parts and associated engineering support, delivered on both planned and reactive bases to support fleet maintenance and availability. This is a rolling-stock engineering and maintenance requirement, classified under repair and maintenance services for rolling stock. The buying organisation is First Great Western Limited, trading as GWR. Services are required across the United Kingdom, covering the fleet and its maintenance operations rather than a single fixed delivery site. The requirement is suited to engineering businesses with established capability in rail HVAC systems, component repair and overhaul, technical testing and responsive maintenance support.

The procurement is complete and has been awarded by direct award to KPL Engineering Limited trading as Pullman AC. The award date is 21 September 2026. Its value is £1,100,000 excluding VAT and £1,320,000 including VAT. The contract period runs from 2 November 2026 to 2 November 2027, with a possible extension to 2 November 2028. GWR selected the incumbent to maintain compatibility and continuity with existing equipment and established repair requirements, avoiding additional technical assessment, competency assurance, testing and engineering approval. The arrangement may be extended while GWR prepares a longer-term competitive procurement. The award is above the relevant threshold and covers a single completed requirement. The procurement is subject to the utilities regime and uses the Procurement Act 2023 legal basis.

This award shows sustained demand from GWR for specialist rail HVAC component support, including planned and reactive repairs, refurbishment, overhaul, diagnostics, testing, replacement parts and engineering advice. A credible future competitor would need demonstrable experience maintaining components fitted to an existing rolling-stock fleet, with the technical competence to work compatibly with established equipment and repair standards. Strong capability in fault diagnosis, controlled testing, overhaul and refurbishment would be important, alongside access to suitable replacement parts and engineering resources. Suppliers would also need to support fleet availability through responsive maintenance and manage the assurance associated with competency, technical assessment and engineering approval. The incumbent is an SME, indicating that a focused specialist engineering business, potentially with relevant rail-sector partnerships and robust operational capacity, can serve this type of requirement.

## Notice

GWR requires specialist repair, overhaul, servicing and technical support for components used across its rolling stock fleet. The requirement includes component repair and refurbishment, fault diagnosis, testing, overhaul, replacement parts and associated specialist engineering support. Services will be provided on a planned and reactive basis as required to support fleet maintenance and availability.

### Procurement Information

KPL Engineering Limited trading as Pullman AC currently provides specialist repair, overhaul and technical support for components used within GWR's existing rolling stock fleet. Continuity of the existing arrangements is required to maintain compatibility with existing equipment and established repair and overhaul requirements. Changing supplier may require additional technical assessment, competency assurance, testing and engineering approval, resulting in disproportionate technical difficulty, additional cost and potential delays to fleet maintenance and availability. The direct award provides continuity of these services while GWR prepares and undertakes a full competitive procurement exercise in accordance with the Procurement Act 2023 for the longer-term requirement.
