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.
For blocks of flats in Powys, we assess whether individual units or a communal system suits the building and how it is managed. On busy Powys high streets, deliveries and crane lifts are scheduled around access restrictions and opening hours. Landlords and managing agents in Powys can phase the work to keep tenants and staff comfortable during the switchover.
Who it suits
- Buildings with roof or yard space for outdoor plant
- 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
- Premises that also want cooling in some areas
Grants and rules for heat pumps in Wales
In Wales 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; £2,500 for air-to-air). The MCS-certified installer named in your quote applies to Ofgem for you, and the grant comes off your quote.
There is no VAT on installing a heat pump anywhere in the UK, Wales included, until 31 March 2027. Planning rules for heat pumps in Wales are set by the Welsh Government and differ from England's, so the surveyor checks the unit position against them.
Prices
Commercial systems are priced after a site survey and load calculation.

Commercial heat pump installation questions
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 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.
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.
