HVAC Contracts and Tenders

See open HVAC tenders and awarded contracts for the UK public sector.

HVAC procurement covers planned and reactive maintenance of air conditioning, ventilation and chiller plant, air handling unit replacement and refurbishment, and HVAC installation within building refurbishments and new builds. Train operators also tender HVAC overhaul, spares and support for their fleets, and laboratory and firearms range ventilation comes up as well.

HVAC maintenance is mostly let as multi-year term contracts across several sites, or as a lot inside frameworks such as NHS Shared Business Services hard facilities management and the CPC minor works dynamic purchasing system. Councils, NHS trusts, universities, housing associations and police bodies are the main buyers of building HVAC.

  • What counts as an HVAC tender in UK public procurement?

    HVAC tenders cover heating, ventilation and air conditioning work: planned and reactive maintenance, installation of new units, and servicing of boilers, chillers, air handling units and ductwork. The category sits apart from general building services work such as electrical or lift maintenance, and from heat pump-specific decarbonisation contracts, which UK buyers tend to procure and describe separately.

  • What CPV codes are used for HVAC contracts?

    HVAC work is most commonly classified under CPV code 45331000 (Heating, ventilation and air-conditioning installation work) and 42512300 (HVAC packages), and 71314310 (Heating engineering services for buildings). Notices sometimes carry general building maintenance codes as well, so the codes alone do not capture every relevant contract.

  • Are HVAC maintenance contracts usually long-term agreements?

    Yes, most run for two to five years. UK public buyers typically procure HVAC maintenance as term contracts or framework agreements covering multiple sites, with planned preventative maintenance visits built in alongside reactive call-out cover for breakdowns and emergency repairs.

  • Which public bodies procure the most HVAC contracts?

    NHS trusts, further education colleges, universities, housing associations and local authorities all publish HVAC tenders regularly, since each manages estates that need heating and ventilation kept running. Transport and emergency services bodies also appear regularly for depot and station plant.

  • Which frameworks are used to buy HVAC services in the UK public sector?

    HVAC work is bought through NHS Shared Business Services frameworks and the CPC minor works dynamic purchasing system. The NHS SBS hard facilities management framework has a lot for ventilation and air conditioning, which NHS trusts use to replace air handling units and chillers. A separate NHS SBS framework covers the design, cost management and project support consultancy behind HVAC plant upgrades, and bodies such as the Met Office and NHS Property Services have called off from it.

    The CPC minor works dynamic purchasing system is used by colleges and housing groups, including for managed HVAC maintenance and for air conditioning and air handling unit works, through its mechanical works lot.

  • How do I find HVAC contracts before they are formally tendered?

    Read capital programmes, planned maintenance schedules, estate condition surveys and early market engagement notices, which show HVAC work coming due ahead of a notice. On Stotles you can track those signals and the buyers behind them, then follow a notice from pre-tender through to award.
