OJEU - F5 - Contract Notice (Utilities)
Summary of the contracting process

ScotRail Trains Limited procured heating, ventilation and air conditioning support for HVAC units fitted to its Class 158 and Class 170 train fleets. The requirement covers maintenance and repair of the onboard units, supporting their continued operation. The work is delivered in Edinburgh and Glasgow. This is a specialist rail engineering services requirement focused on train HVAC systems rather than general building heating or ventilation. The buyer is ScotRail Trains Limited, based in Glasgow, and operates the trains receiving the services.

The procurement is complete and awarded to Tidyco Ltd. ScotRail used a negotiated procedure following a prior call for competition, with a successive reduction of candidates; at least three candidates were to be invited to the second stage. The contract was signed on 16 September 2026 and is active. Its recorded value is £880,800. The contract period is 1,080 days, with extension options of up to three years in three successive one-year extensions. The tender was estimated at £600,000. Bids were assessed on technical quality, weighted at 60%, and price, weighted at 40%. The requirement was arranged as one lot, and variant bids were not allowed.

The award demonstrates demand from ScotRail for dedicated maintenance and repair of HVAC equipment on its Class 158 and Class 170 trains. Suppliers well placed to compete when this requirement returns will need credible rail-sector engineering capability, including the technical expertise and service capacity to support these specific fleets across Edinburgh and Glasgow. The 60% weighting for technical quality makes evidence of a robust technical approach especially important, alongside competitive pricing. The contract’s scale and potential for extensions indicate a sustained support requirement rather than a one-off repair job. Tidyco Ltd’s selection provides a market reference point for the type of supplier that met ScotRail’s requirement; competitors should be ready to demonstrate equivalent capability and reliable delivery for train-mounted HVAC systems.
