Because every building differs, commercial work is priced after a site survey rather than from a guide price. We plan the installation around your operation, including phased or out-of-hours working where the building must stay open. Funding for non-domestic buildings depends on the building, its size and the nation it is in, so we check what, if anything, applies at survey.
For blocks of flats in Cambridgeshire, we assess whether individual units or a communal system suits the building and how it is managed. Premises in Cambridgeshire close to homes need careful plant siting and, where required, an acoustic assessment. Businesses across Cambridgeshire can arrange a site survey of premises in Cambridgeshire before any equipment is specified.
Who it suits
- Landlords and managing agents planning low-carbon upgrades
- Buildings with roof or yard space for outdoor plant
- Offices, shops and small commercial premises replacing gas or oil boilers
- Premises that also want cooling in some areas
Grants and rules for heat pumps in England
In England the Boiler Upgrade Scheme gives £7,500 towards an air source heat pump (£9,000 if it replaces oil or LPG, from 21 July 2026 to 31 March 2027), and since 28 April 2026 a valid EPC is no longer needed. The grant is applied for by the MCS-certified installer and shown as a deduction on your quote.
Installing heat pumps is zero-rated for VAT across the UK until 31 March 2027. Since 29 May 2025, permitted development in England allows up to two air source heat pumps on a house, each up to 1.5 m³, with no blanket 1 m boundary rule — the installation must still meet the MCS planning standards, including the noise check. Listed buildings, flats and some conservation-area positions need extra consent, which we check at survey.
Prices
Commercial systems are priced after a site survey and load calculation.

Commercial heat pump installation questions
How much does a commercial heat pump cost?
Commercial heat pumps are priced after a site survey, because cost depends on the building's heat load, the number and size of units, where the plant goes, access, and any changes to the heating system inside. We then give a written quote setting out the equipment, the programme and what is included. There is no reliable guide price for commercial work without seeing the building.
What is a cascaded heat pump system?
A cascaded system links two or more outdoor heat pump units to one controller, which runs as many units as demand needs. On mild days one unit might run; on cold days all of them. This keeps each unit working efficiently, spreads wear across the units and means heating can usually continue at reduced output if one unit needs repair or servicing.
Can heat pumps go on a flat roof?
Yes, flat roofs are a common position for commercial plant. The roof needs a structural check for the weight of the units and their frames, and the installation usually needs a lifting plan, anti-vibration mounts, drainage for defrost water and safe access for maintenance. Pipe and cable routes from the roof into the building are planned at survey.
Are there grants for commercial heat pumps?
It depends on the building, its size and use, who owns it and which nation it is in, and the rules differ from those for homes. We check at survey whether any scheme applies to your building in England, Wales, Scotland or Northern Ireland, and we do not include a grant in the quote unless eligibility has been confirmed.
