Design starts with the load: a heat loss calculation for the building, its occupancy and opening hours, how much hot water it uses and whether any spaces need cooling. From that we propose plant sizes and positions, on a roof, in a yard or in a plant enclosure, with the structural, electrical and noise checks each position needs. Larger plant may need a three-phase supply, which the network operator may need to provide or confirm.
On busy Merseyside high streets, deliveries and crane lifts are scheduled around access restrictions and opening hours. Premises in Merseyside close to homes need careful plant siting and, where required, an acoustic assessment. Businesses across Merseyside can arrange a site survey of premises in Merseyside before any equipment is specified.
Who it suits
- Landlords and managing agents planning low-carbon upgrades
- Buildings with roof or yard space for outdoor plant
- Blocks of flats and houses in multiple occupation needing shared or per-flat systems
- Premises that also want cooling in some areas
Grants and rules for heat pumps in England
Homes in Merseyside 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 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.
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.
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.
