What are Air Source Heat Pumps?

Air source heat pumps are a sustainable alternative to conventional fossil fuel heating systems. In essence, air source heat pumps take advantage of the heat energy present in the air and transform it into usable energy for heating dwellings. The heat pumps we install are "air to water" systems, which means that they draw heat from the air and transfer it to "wet" heating systems like radiators, underfloor heating and hot water.

Who Pays For The Air Source Heat Pump & Installation?

The money to pay for Air Source Heat Pump & Installation comes from energy suppliers as part of a government scheme to reduce carbon emissions, known as the Energy Companies Obligation (ECO4). An initial survey is carried out by an approved air source heat pump installer, the installer completes the work on the approved property and the installer then invoices the utility companies for the grant amount.


If for any reason you don’t qualify for the full grant you could still qualify for a large contribution to the cost of the work, meaning a small amount is to be paid.
