An air source heat pump installation is an effective, low-carbon way of heating your home. With the Government’s Renewable Heat Incentive providing cash payments for eligible installations, installing an air source heat pump is an attractive investment.

Air source heat pumps can be installed in both new and existing properties, and provide a low-maintenance, energy-efficient heating system.

Is your property suitable for an ASHP?



To work efficiently, air-source heat pumps require a well-insulated house, in some cases older properties may require insulation upgrades prior to installing an air-source heat pump.

Access to mains gas

Properties with access to main gas are suitable for an air source heat pump installation, although a greater return on investment will be seen when switching from oil, LPG or electric heating systems.

Planning permission

Air source heat pump installations do not require planning permission.

Heat emitter consideration

Air source heat pumps work most efficiently with low-flow temperature emitters, making underfloor heating the perfect partner. Traditional radiators can still be used with air-source heat pumps, although the size of these will need to be considered.

Air source heat pump installation processes

The installation process for an air source heat pump in a single dwelling would typically take 5 working days, which includes commissioning. Unlike a ground source heat pump installation no groundworks are required, and therefore the process is more akin to that of a traditional gas or oil boiler.

The air source heat pump unit will be fitted to the outside of the property, in a position with good airflow ensuring that nothing is blocking the unit.

The unit, sized around 1m wide, 1m high and 30cm deep, will be bolted to the ground, or brackets connecting it to the property in order to secure it.

Once the air source heat pump unit is installed, it will be connected to the hot water cylinder. The unit may, depending on your existing system, easily link to your water tank with limited additional work. Larger radiator units may be needed to replace your existing radiators.

As air-source heat pumps have very few moving parts, they require less ongoing maintenance than traditional heating systems. We recommend an annual service to ensure that your system is running at its optimum efficiency.

From initial enquiry to ongoing service and maintenance, we are on hand to answer questions and guide you through the process of your installation.

Renovating a 1970s property and replacing oil for air

When Paul moved into his home in East Leake he discovered that the best option for replacing the 45-year-old oil boiler was an air source heat pump. Paul carefully compared the cost of replacing the old oil boiler with an up-to-date condensing oil boiler or an air source heat pump system. He found that thanks to the Renewable Heat Incentive scheme, the installation costs were almost identical, and the heat pump would deliver lower running costs and have a much more positive environmental impact.
