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.
Businesses across Renfrewshire and Inverclyde can arrange a site survey of premises in Renfrewshire and Inverclyde before any equipment is specified. Landlords and managing agents in Renfrewshire and Inverclyde can phase the work to keep tenants and staff comfortable during the switchover. Offices and shops in Renfrewshire and Inverclyde with a flat roof or rear yard often have space for outdoor plant, checked for structure and access.
Who it suits
- Offices, shops and small commercial premises replacing gas or oil boilers
- Landlords and managing agents planning low-carbon upgrades
- Buildings with roof or yard space for outdoor plant
- Premises that also want cooling in some areas
Grants and rules for heat pumps in Scotland
In Scotland, heat pump funding comes through Home Energy Scotland rather than the Boiler Upgrade Scheme: a grant of up to £7,500 (up to £1,500 extra for eligible rural and island homes) and an optional interest-free loan of up to £7,500. For a home in Renfrewshire and Inverclyde, apply and receive the written offer before the installation date is fixed.
There is no VAT on installing a heat pump anywhere in the UK, Scotland included, until 31 March 2027. Scottish permitted development rules and building standards apply, and the surveyor checks the unit position and any listed or conservation-area constraints.
Prices
Commercial systems are priced after a site survey and load calculation.

Commercial heat pump installation questions
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 you install without closing the business?
Usually, yes. Outdoor plant, pipework and controls can often be installed while the existing heating still runs, with the switchover planned for a short window, such as a weekend or a quieter time of year. Work inside occupied areas can be phased. The programme in your quote sets out what happens when, so you can plan staff and customers around it.
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.
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.
