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 Lincolnshire, we assess whether individual units or a communal system suits the building and how it is managed. On busy Lincolnshire high streets, deliveries and crane lifts are scheduled around access restrictions and opening hours. Businesses across Lincolnshire can arrange a site survey of premises in Lincolnshire before any equipment is specified.
Who it suits
- Premises that also want cooling in some areas
- Blocks of flats and houses in multiple occupation needing shared or per-flat systems
- Landlords and managing agents planning low-carbon upgrades
- Buildings with roof or yard space for outdoor plant
Grants and rules for heat pumps in England
Homes in Lincolnshire can use the Boiler Upgrade Scheme, which takes £7,500 off the cost of an air source heat pump when it replaces fossil-fuel or electric heating. Replacing oil or LPG heating qualifies for £9,000 for installations from 21 July 2026 to 31 March 2027, and air-to-air systems for £2,500. The MCS-certified installer named in your quote applies for the grant and deducts it from the price.
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
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.
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.
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 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.
