We offer a personalised and individual service, designing your heating system for your home specifically, whether you need to retrofit a system within your existing property, a new build property, a barn conversion or property renovation.

Benefits of air source heat pumps:

Air source heat pumps are one of the most energy-saving and environmentally friendly technologies providing hot water and heating to your home, working at around 300% efficiency. This means that it will deliver more heat to your home for every penny spent, compared to a new conventional oil or gas heating system which works at around 90% efficiency.

You can also claim government incentives to offset some of the cost of your installation, our government incentives page will give you full and up to date information on the current schemes.

Frequently asked questions about Air Source Heat Pumps

How do Air Source Heat Pumps work?

An ASHP uses energy from the outdoor air. Air is pulled across a heat exchanger inside the heat pump where the energy is extracted by refrigerant gases. These gasses are compressed via a compressor to give useable heat.  This heat is transferred to your heating system in the same way as a conventional boiler sends heat to your radiators, underfloor heating or hot water cylinder so it is ready whenever it is needed.

How much will an Air Source Heat Pump installation cost?

An example of a typical 3-bedroom detached bungalow that has an oil boiler and 9 radiators will cost approximately £18,000 to change the heating system to Air Source Heating.

You could expect to receive government grant of £5,000 through the Boiler Upgrade Scheme (BUS).

It is estimated you would benefit from fuel savings each year, depending on your current electricity provider unit rates.

The costs involved in installing a system include the following:

  • Removal of the existing system.
  • Custom design of a heating system for your property.
  • Installation of the air source heat pump (unit fitted outdoors).
  • Installation of a new cylinder that has an increased size primary coil fitted.
  • Installation of a buffer vessel (another cylinder for the heating system fluid).
  • Replacement of the radiators with new, larger radiators.
  • Replacement of the current heating controls.
  • Electrical wiring of the new system. Often a new supply will need to be run from the consumer unit to the outdoor air source heat pump.
  • Plumbing required to adapt the old heating and hot water systems to the new heat pump and radiators.
  • Registration and certification for Microgeneration Certification Scheme so that you will be eligible for the Boiler Upgrade Scheme.

Will I have lower energy bills if I install an ASHP?

If you are changing from LPG, oil or direct electric there are considerable savings to be made in your annual running costs.

An air source heat pump generates 3 times the energy it consumes, this means that for every 1kw of electricity that you pay for, an ASHP can produce 3kw of heat for your home.

Does the government offer incentives to install an ASHP?

The government currently offers the Boiler Upgrade Scheme which offers a £5,000 grant towards the installation of an air source heat pump.  This grant is available until 31st March 2025. Full up to date information on the current schemes and eligibility is available and detailed on our Incentives page.

Can I use my existing radiators with a new Air Source Heat Pump?

If the radiator in a room is sized correctly for that room and currently being heated by a gas or oil boiler, then it is not likely to be suitable to be used with an ASHP.  A new radiator sized correctly to work with an air source heat pump will be needed.

How many years will my ASHP run for?

The external unit is expected to last up to 20 years on a system which has been designed and installed correctly.
