Why a heat pump

More than an upgrade — a commitment.

Choosing an air source heat pump is a commitment to efficiency, sustainability and long-term savings.

Save on energy bills, year-round comfort

Efficiently heats in winter and cools in summer, providing cost-effective comfort all year round.

Eco-friendly and carbon-reducing

Reduces your reliance on fossil fuels, creating a genuinely low-carbon, sustainable home.

Government incentives

Eligible for grants such as the Boiler Upgrade Scheme, making installation considerably more affordable.

How it works

Three times more energy out than goes in.

Air source heat pumps are remarkably efficient, delivering up to three times more energy than the electricity they consume.

  1. 01

    Absorbing heat

    The outdoor unit absorbs heat from the outside air — even when it’s cold — and transfers it into a refrigerant.

  2. 02

    Compressing heat

    The refrigerant is compressed, raising its temperature to a useful level for your home.

  3. 03

    Transferring heat

    That heat passes into your heating system, providing warm air, warm radiators and hot water.

The economics

Economical, clean and quietly efficient.

On average, homeowners save up to 30% on heating bills compared with traditional systems — actual savings depend on your current setup and usage.

Modern units are quiet and unobtrusive, operating at a sound level comparable to a standard refrigerator, and run efficiently in temperatures as low as −15°C.

We’ll assess whether your existing radiators are suitable, size the system correctly, and help you check eligibility for the Boiler Upgrade Scheme.

“I was very impressed with this company from start to finish. Their quotation and accompanying project plan was extremely comprehensive, and they answered any questions I had immediately. My panels and battery system (Sigenergy) took two days to fit, and the guys were all very friendly, worked extremely hard and long hours, and left everything very neat and tidy, a real quality installation. All the post installation documentation was provided quickly as promised, they handled all the liaison with the network provider, and helped set up the app. The system is working really well and I would recommend this company wholeheartedly.”

FAQs

Common questions.

Can air source heat pumps work in cold weather?

Yes. They are designed to work efficiently in temperatures as low as −15°C, which makes them well suited to the UK climate.

How much can I save on energy bills?

On average, homeowners save up to 30% on heating bills compared to traditional heating systems. Actual savings depend on your current energy usage and setup.

Are air source heat pumps noisy?

Modern units are designed to be quiet and unobtrusive. Most operate at a sound level comparable to a standard refrigerator.

What incentives are available?

Homeowners may be eligible for the Boiler Upgrade Scheme (BUS), which offers grants to reduce the cost of installing low-carbon heating. We can help you determine eligibility and assist with the application.

Can I use one with my existing radiators?

In most cases yes. Some older radiators may need upgrading to ensure maximum efficiency, and we’ll tell you plainly if yours do.

Does a heat pump work well with solar?

Very well. A heat pump runs on electricity, so pairing it with solar PV and a battery means much of your heating can be powered by energy you generated yourself.
