Receive up to £11,500 through the Renewable Heat Incentive by using an MCS Certified heat pump installer.

An air source heat pump works much like a fridge, only it’s in reverse so it heats your home.

Outside air is blown over a network of tubes filled with a refrigerant.

This warms up the refrigerant and it turns from a liquid into a gas.

The refrigerant transfers its heat to water, making it warm.

This warm water is sent around your radiators or underfloor heating just like a conventional gas or oil system would, heating your home.


At K Cahill Renewables, we offer groundbreaking renewable energy solutions. We specialise in the design, supply, installation and maintenance of solar panels, air source heat pumps and other renewable energy technologies.

There is no doubt that, conventional energy sources are drastically depleted and have had a devastating impact on the environment.

Solar power has the potential to harvest the power from the sun and convert it into usable power.

The result?

Sustainable, affordable power sources for our customers that are not dependent on finite resources.

What’s more, most heat pump installations pay for themselves and in most cases even earn money within a matter of years.

If you own a property, air source heat pumps or solar panels are a worthy investment; they can add to the resale value of your property and will provide you with free, ecological power for generations.

No job is too big or too small for us to take on.
