With energy bills on the rise and more people wanting to do their bit for the planet, many households across Lancashire are exploring low-carbon ways to heat their homes. If you’ve been looking into alternatives, you might have found yourself wondering about air source heat pumps. So, let’s get to the key question: how much do they cost?
Let’s break it down.
What Is an Air Source Heat Pump?
In simple terms, an air source heat pump pulls thermal energy from the air outside—even when it’s cold—and uses it to heat your home and hot water. It runs on electricity, so it’s often cleaner and cheaper than heating systems that burn oil or gas.
What is the Average Cost?
In 2025, the average cost of supplying and installing an air source heat pump in Lancashire typically ranges between £7,000 and £14,000+, depending on several factors such as the size of your home, the brand and type of unit, and how much additional work (like radiator upgrades or insulation) is required.
The table below shows an average cost for the pump itself, installation, and any extra equipment like a hot water cylinder.
| Property Type | Estimated ASHP & Installation Cost |
| Small flat or 1 bed home | £7,000 – £9,000 |
| 2-3 bedroom house | £9,000 – £12,000 |
| Larger homes (4+ bed) | £12,000 – £14,000+ |
These costs are representative and don’t reflect exactly what you’ll pay. Heat pump installations are priced on a case-by-case basis.
What Affects the Cost?
There’s no one-size-fits-all answer because the cost depends on a few key variables:
1. Your Home’s Size and Layout
Larger homes or homes with complex layouts will need a bigger system to deliver adequate heating, increasing the overall cost.
2. Current Heating System
If you’re replacing a gas boiler, you may need to upgrade radiators or your hot water cylinder. If you have underfloor heating, that’s a bonus—it works really efficiently with heat pumps.
3. Insulation Levels
A well-insulated home requires less energy to heat, so the heat pump won’t need to work as hard. If your home is poorly insulated, you may need to spend extra on insulation upgrades before fitting the system.
4. Installation Complexity
The more straightforward the install, the cheaper it will be. If extra pipework, electrical upgrades, or external work is needed, expect a higher quote.
What funding is available for air source heat pumps?
If you live in England or Wales, you could get £7,500 towards an air source heat pump through the Boiler Upgrade Scheme (BUS). Originally due to end in 2025, the scheme has now been extended and is scheduled to run until 31 March 2028.
