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.
Businesses across County Down can arrange a site survey of premises in County Down before any equipment is specified. For blocks of flats in County Down, we assess whether individual units or a communal system suits the building and how it is managed. On busy County Down high streets, deliveries and crane lifts are scheduled around access restrictions and opening hours.
Who it suits
- Buildings with roof or yard space for outdoor plant
- Offices, shops and small commercial premises replacing gas or oil boilers
- Landlords and managing agents planning low-carbon upgrades
- Blocks of flats and houses in multiple occupation needing shared or per-flat systems
Grants and rules for heat pumps in Northern Ireland
The Boiler Upgrade Scheme covers England and Wales only, and there is currently no dedicated heat pump grant for homeowners in Northern Ireland. Our quote for a home in County Down is therefore shown without a grant deduction; if support becomes available we will tell you how it applies.
Installing heat pumps has been zero-rated for VAT in Northern Ireland since 1 May 2023, in line with the rest of the UK, until 31 March 2027. Northern Ireland has its own permitted development rules and building regulations, and 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 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.
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.
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.
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.
