Replacing gas heaters
Swap warm-air gas heaters or old boilers in offices and showrooms for efficient heat pumps that also cool.
Heating + cooling in one
Air-to-Air Heat Pumps for Business
Air-to-air heat pumps provide efficient heating and cooling from one system: a practical, fast way to decarbonise heating in offices, retail and hospitality.
How they work
Reverse-cycle heating and cooling.
An air-to-air heat pump extracts heat from outdoor air and delivers it indoors as warm air through wall, ceiling, cassette or ducted units. In summer, the cycle reverses to provide cooling. It’s the same technology as modern air conditioning, used as the building’s primary heating.
Because refrigerant pipes are small and there’s no need for radiators or a plant room, installation is usually quicker and less disruptive than other low-carbon heating options, which matters in occupied commercial buildings.
Typical efficiencies mean several units of heat for each unit of electricity, so air-to-air systems can cut energy use substantially compared with direct electric heating, and carbon compared with gas.
Applications
Where commercial air-to-air heat pumps work well.
Replacing electric panels
Direct electric heating is expensive to run. Heat pumps deliver the same comfort for a fraction of the electricity.
Retail & hospitality
Year-round comfort for customers, with heating and cooling from the same units.

Planning an air-to-air heat pump project.
- Fresh air: heat pumps recirculate air, so ventilation needs to be considered separately
- Hot water: not provided, so a point-of-use or separate solution may be needed
- Controls: sensible setpoints, schedules and lockable controllers protect efficiency
- Electrical capacity: we check supply capacity early
- Funding: the £2,500 Boiler Upgrade Scheme grant for air-to-air heat pumps (since April 2026) is for homes, not commercial premises. Businesses should discuss tax treatment of plant with their accountant

Useful answers
Common questions
Is an air-to-air heat pump the same as air conditioning?
Essentially yes: it’s reverse-cycle air conditioning used as a heating system as well as for cooling.
Will it heat our building in winter?
Correctly sized systems heat effectively through typical UK winters. We size for your building’s heat loss.
Can it replace our boiler?
For space heating in many offices and shops, yes. Hot water needs a separate solution.
Is there funding?
The current £2,500 air-to-air grant is for domestic properties only. Public sector organisations may have access to decarbonisation funding, so check what applies to you.
