A commercial heat pump installation is an air source system designed for a non-domestic or multi-unit building, such as an office, shop, surgery, small workshop or block of flats, where the heating load and hours of use are larger or more varied than in a single home. Rather than one unit, these systems often use several outdoor units working together, called a cascade, so output can step up and down with demand and one unit can be serviced while the others keep running.
Premises in Glasgow and Dunbartonshire close to homes need careful plant siting and, where required, an acoustic assessment. For blocks of flats in Glasgow and Dunbartonshire, we assess whether individual units or a communal system suits the building and how it is managed. Businesses across Glasgow and Dunbartonshire can arrange a site survey of premises in Glasgow and Dunbartonshire before any equipment is specified.
Who it suits
- Landlords and managing agents planning low-carbon upgrades
- Blocks of flats and houses in multiple occupation needing shared or per-flat systems
- Offices, shops and small commercial premises replacing gas or oil boilers
- Buildings with roof or yard space for outdoor plant
Grants and rules for heat pumps in Scotland
The Boiler Upgrade Scheme does not apply in Scotland. Instead, homeowners in Glasgow and Dunbartonshire can apply to Home Energy Scotland for a grant of up to £7,500 towards a heat pump, with up to £1,500 more for eligible rural and island homes, plus an optional interest-free loan of up to £7,500. You need a written funding offer before any work starts.
Installing heat pumps is zero-rated for VAT across the UK until 31 March 2027. Scotland has its own permitted development rules for air source heat pumps and its own building standards, so we confirm what applies to your property at survey.
Prices
Commercial systems are priced after a site survey and load calculation.

Commercial heat pump installation questions
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.
Can commercial heat pumps provide cooling as well?
Some can. Air-to-water heat pumps are mainly used for heating and hot water, but certain units can also supply chilled water for fan coil units. Air-to-air systems heat and cool directly through indoor units and suit offices and shops where cooling is wanted. The survey identifies which areas need cooling and recommends a system to match.
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.
