Why Choose an Air Source Heat Pump for Your Home?
Key Benefits of Air Source Heat Pump installation:
- Can lower running costs compared to gas, oil or LPG, particularly on the right electricity tariff in a well-insulated home
- Highly efficient – typically delivers 3–4 units of heat for every unit of electricity used (SCOP 3.0–4.0)
- Lower carbon footprint than fossil fuel heating
- Works perfectly with underfloor heating and modern radiators
- Eligible for £7,500 government grants
- Long lifespan (15–20+ years)
- Low maintenance requirements
Modern air source heat pumps deliver consistent heating even during cold UK winters, making them suitable for homes throughout our service area that are moving away from fossil fuels.
What Is an Air Source Heat Pump?
An air source heat pump (ASHP) is a renewable heating system that extracts heat from the outside air and converts it into usable warmth for your home and hot water.
Even when temperatures drop below freezing, air still contains heat energy. The heat pump captures this energy and upgrades it using electricity – producing more heat energy than the electricity it consumes.
This makes air source heat pumps a highly efficient alternative to traditional gas boilers.
How Does an Air Source Heat Pump Work?
Air source heat pumps work by transferring heat rather than generating it.
The process includes:
- Absorbing heat from the outside air
- Compressing the heat to raise its temperature
- Transferring the heat into your home’s heating system
- Heating water stored in a hot water cylinder
Because the system moves heat instead of burning fuel, it can deliver 3–4 units of heat for every unit of electricity used.

How Much Does an Air Source Heat Pump Cost in the UK?
The cost of installing an air source heat pump typically ranges between:
£8,000 – £14,000 (before grants)
Final cost depends on:
- Property size and heat demand
- Existing heating system
- Radiator or pipework upgrades
- Insulation levels
- Hot water cylinder installation
Boiler Upgrade Scheme Grants
Eligible homeowners can receive £7,500 towards an air-to-water heat pump through the Boiler Upgrade Scheme. Until 31 March 2027, this rises to £9,000 for qualifying off-gas-grid properties replacing oil or LPG heating.
As MCS-certified installers, we check eligibility, manage the installer application and guide you through the process.
Air Source Heat Pump vs Gas Boiler: How They Compare
| Feature | Air Source Heat Pump | Gas Boiler |
|---|---|---|
| Typical installation cost | £8,000–£14,000 (before grants) | [INSERT YOUR TYPICAL RANGE – check against your Gas Boiler Installation page] |
| Efficiency measure | SCOP typically 3.0–4.0 (delivers 3–4 units of heat per unit of electricity used) | Thermal efficiency typically 90–94% |
| Running costs | Can be lower than gas on the right tariff in a well-insulated home – varies by property and usage | Typically lower cost per kWh than electricity, though subject to gas price rises |
| Carbon emissions | Lower – improves further as the electricity grid decarbonises | Higher – direct fossil fuel combustion |
| Government grants | Up to £7,500–£9,000 available (Boiler Upgrade Scheme) | Not available |
| Typical lifespan | 15–20+ years | 10–15 years |
Heat pump and boiler efficiency are measured differently and aren’t directly comparable figure-for-figure. Figures above are typical/indicative and vary by property size, insulation, existing system and electricity tariff – book a free assessment for costs and savings specific to your home.
For well-insulated homes on the right tariff, an air source heat pump can offer lower running costs and lower carbon emissions over its lifetime than a gas boiler — book a free assessment to see what that looks like for your property.

Air Source Heat Pump FAQs
Are air source heat pumps efficient in winter?
Yes. Modern air source heat pumps operate efficiently in UK winter temperatures, typically achieving a Coefficient of Performance (COP) of 2.5–3.5 even at 0°C. This means they produce 2.5–3.5 units of heat for every unit of electricity consumed.
Do air source heat pumps work with radiators?
How noisy are air source heat pumps?
Do I need planning permission in London?
Many domestic air source heat pump installations in England can be completed under permitted development rights, provided the relevant limits and MCS Planning Standards are met. Different requirements can apply to listed buildings, conservation areas, flats and properties with planning restrictions, so we check the requirements for your address before installation.
