Heat Pump Tenders

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

Heat pump procurement covers air source (ASHP) and ground source (GSHP) installations, most often replacing a gas boiler as part of a decarbonisation retrofit at a school, fire station, housing block or hospital site. Housing associations and combined authorities run much of the volume, frequently as one measure inside a wider low-carbon retrofit programme rather than a standalone heat pump contract.

Stotles tracks 3,065 heat pump notices to date, with 1,282 already awarded.

Frequently asked questions

Frequently asked questions about heat pump, ASHP, GSHP in the UK public sector.

  • What counts as a heat pump tender?

    A heat pump tender covers the supply, installation or design of an air source (ASHP) or ground source (GSHP) heat pump, whether as a standalone replacement for an existing heating system or as one measure inside a wider retrofit or decarbonisation project.

  • Who buys heat pump installations in the public sector?

    Housing associations, combined authorities, NHS trusts and fire and rescue services are frequent buyers, usually replacing a gas-fired heating system at a single site as part of a low-carbon retrofit. Councils also run larger multi-site retrofit programmes covering housing stock or public buildings.

  • Is a heat pump usually installed on its own or as part of a wider project?

    Most often as part of something wider. A heat pump swap frequently sits inside a bigger decarbonisation or fabric-first retrofit project covering insulation, controls and ancillary equipment at the same time, rather than going out as its own isolated tender.

  • What's the difference between ASHP and GSHP procurement?

    An air source heat pump (ASHP) draws heat from outside air and is the more common retrofit choice for an existing building. A ground source heat pump (GSHP) needs ground loops or boreholes, so it shows up more often in new-build or larger estate projects where that groundwork is already planned.
