Heat pumps and running costs

How much does a heat pump cost to run?

A heat pump can be a smart long-term investment, offering energy efficiency and lower carbon emissions. Like many major home upgrades, it does come with upfront costs—installation typically starts around £11,000, depending on the size and layout of your home. But don’t let the initial price tag put you off. The real value lies in the running costs, where heat pumps can start to pay for themselves over time.

Heat pump running costs of a home.

Every home is different—just like a fingerprint. That’s why the cost of running a heat pump can vary based on several key factors unique to your property, which are listed below:

• The size of your home:
  Heating a compact cottage costs less than warming a large family home — size makes a big difference.

• How well your home is insulated:
  Good insulation helps keep the heat in, meaning your heat pump doesn’t have to work as hard (or cost as much to run).

• Your current energy rates:
  We’ll help you break down your tariff and usage, so you can see exactly where the savings lie.

• Your heating preferences:
  Whether you like things warm and cosy or prefer a cooler home, we’ll tailor your setup to suit your comfort and lifestyle.

Air source heating cost 

Air source heat pumps are the quiet champions of home heating. They draw warmth from the outside air—even on cold days—and use it to heat both your home and your water. The best part? They do it all with impressive energy efficiency.

So, what can you expect to pay? On average, running an air source heat pump costs between £450 and £1,200 per year, depending on your home’s size and how much heating you use. Think of it like trading in a gas-guzzler for a hybrid – you’ll start to notice the savings in your everyday energy costs. And if you’re replacing a gas boiler, you’ll completely eliminate your gas bill. While your electricity usage will go up, your efficient heat pump uses power far more effectively than traditional heating systems.

Air source heat pump and underfloor heating cost.

Combining an air source heat pump with underfloor heating creates the ultimate setup for comfort and efficiency. Underfloor heating is designed to perform best with low water temperatures—exactly what heat pumps provide. Together, they create a perfectly balanced and energy-smart way to heat your home.

How much could I save with an air source heat pump?

Now for the exciting bit: potential savings! Let’s see how your current heating system stacks up against a heat pump. Keep in mind, these figures are estimates—actual savings will vary based on factors like your home’s location, age, and how well it’s insulated.

Estimated annual savings are based on installing a standard air source heat pump in an average-sized, three-bedroom detached home. Actual savings will vary depending on factors like your property size, electricity usage, and the type and age of your existing heating system—whether that’s electric storage heaters, oil, or LPG. Figures referenced are from the Energy Saving Trust.

Efficiency of a heat pump.

Heat pumps are the high performers of home heating. For every unit of electricity they consume, they produce 3 to 4 units of heat—an impressive efficiency of 300–400%. In comparison, even the most efficient gas boilers top out at around 90%. It’s easy to see why heat pumps are quickly becoming the go-to solution for low-carbon, energy-efficient heating.

Your EPC rating matters
Your home’s Energy Performance Certificate (EPC) gives a good indication of how well it holds heat. For a heat pump to work efficiently, a rating of D or above is ideal. If your rating is lower, don’t worry — upgrading your insulation can make a big difference and help you get the most from your system.

Why insulation is essential
Good insulation is the foundation of an energy-efficient home. From the loft to the walls and even under the floor, improving insulation helps your heat pump run more efficiently. The better your home retains heat, the less energy you’ll use — keeping you comfortable while lowering your running costs.

Government grants for heat pumps.

Great news! Government grants are available to help make installing a heat pump more affordable. Through schemes like the Boiler Upgrade Scheme, you could receive up to £7,500 towards the cost of installation—making the switch to low-carbon heating much more accessible.

The Boiler Upgrade Scheme is available for heat pumps commissioned from 1 April 2022. To qualify, you’ll need a valid Energy Performance Certificate (EPC) issued within the last 10 years. Please note that new-build homes are not eligible, and both the property and homeowner must meet specific criteria. For full details and exclusions, visit the official Boiler Upgrade Scheme website.
