Air source heat pumps
Our experienced engineers have the skill to fit air source heat pumps in your home or business, as part of our full renewables offering.
What is an air source heat pump?
Air source heat pumps take heat from the air outside your home and use it as their main source of energy. Much like a fridge working in reverse, outside air passes over a network of pipes filled with refrigerant. This warms the refrigerant, turning it from a liquid into a gas.
That gas then passes through a compressor, which increases the pressure and raises the temperature further. From there, it moves through a heat exchanger, where it releases its heat into your home’s water or air-based heating system, warming your home. As it gives up that heat, the refrigerant cools and condenses back into a liquid, ready to begin the cycle again.
The key benefits
- Lower running costs compared to traditional gas heating
- Even greater savings when paired with solar panels
- No fuel storage needed, freeing up space
- Safe — no gas, no naked flame, no dangerous emissions
- Lower carbon emissions than a fossil fuel boiler
- No more gas bills

Government funding
The UK Government offers grants and incentives to help homeowners move to more efficient, low-carbon heating. Ground and air source heat pumps can currently qualify for support through the Boiler Upgrade Scheme — we’ll confirm exactly what your home’s eligible for as part of your consultation.
Types of renewable energy you could get support with at Custom Heat & Cool:
- Ground source heat pumps
- Air source heat pumps
- Solar thermal heating — benefits from 0% VAT on installation until March 2027, rather than a direct grant
Eligibility
To check your eligibility for Boiler Upgrade Scheme funding, give us a call to discuss your home’s heating needs.

Frequently asked questions about air source heating
Almost all buildings can have pumps fitted, apart from a block of flats. Air Source Heat Pumps are most commonly fitted outdoors, so there needs to be an amount of space outside the building to allow for fitting.
Yes. Air Source Heat Pumps can be installed with existing heating systems and be used to heat radiators.
Yes. Some households will have multiple systems of heating for safety, however these pumps are designed to replace boilers as they are more efficient and better for the environment to run than generic gas or electric boilers.
An Air Source Heat Pump in the UK generally costs around £6-8,000, depending on the size of the building it is intended to heat. However, there are government grants available to either cover or subsidise the cost of installing the unit. Please get in touch with us to find out more about this.
The size of your pump will depend on the size of the area you are trying to heat. Air Source Heat Pumps come in a number of sizes and can heat a variety of buildings at a lower cost than gas or direct electricity. Please get in touch with us to find out more about your requirements.
