HVAC Contracts and Tenders

HVAC procurement covers the servicing, maintenance and repair of heating, ventilation and air-conditioning, including critical air handling units in hospitals, chillers and boilers. Building management system controls servicing, replacement HVAC plant and HVAC spares also come up, and HVAC is often a lot within a wider hard facilities management contract.

Stotles brings together HVAC tenders and contracts from 100+ portals into one search, so you do not have to check each portal separately, and you can set alerts for new opportunities across the UK and Ireland.

If you want to search the government portals directly, Find a Tender carries higher-value contracts across the UK and Contracts Finder carries lower-value contracts in England. Public Contracts Scotland, Sell2Wales and eTendersNI cover Scotland, Wales and Northern Ireland, Ireland's eTenders covers Irish public bodies, and many councils, NHS bodies and housing associations publish on their own e-tendering portals such as ProContract. Most HVAC tenders appear on Find a Tender, and HVAC lots inside facilities management frameworks go only to contractors already on that framework.

Public sector air conditioning maintenance is let as standalone servicing contracts, as measured term contracts by councils and as HVAC lots within facilities management and repairs frameworks. Joining those frameworks opens up call-offs, and NHS trusts, universities and research sites tender critical ventilation maintenance on its own because of the compliance risk.

Engineers working on air-conditioning and refrigeration systems must hold F-Gas certification, and gas boiler work needs Gas Safe registration. Tenders usually set minimum insurance cover, check financial standing and ask for evidence of similar contracts at selection stage. Under the Procurement Act 2023, suppliers can be excluded for certain criminal convictions, insolvency or failure to pay tax.

HVAC work arrives in three main forms: servicing and maintenance contracts that typically run for two to three years, HVAC or mechanical lots inside hard facilities management and repairs frameworks, and quick quotes for one-off replacements. Specialist sites such as hospitals and laboratories also tender individual air handling unit replacements as works projects.

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.

Councils, NHS trusts, universities and colleges, research institutes, housing associations and ports are regular buyers of HVAC services. The Foreign, Commonwealth and Development Office buys HVAC maintenance for embassies overseas, and the Ministry of Defence buys HVAC spares.

Read estates strategies, decarbonisation plans, facilities management contract expiry dates and preliminary 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.
