They take heat from the outside and move it to the inside:
We’ve teamed up with Octopus Energy to help you cut the cost of installing an air source heat pump. If you have a Halifax mortgage and qualify for our Green Living Reward, you can claim £1,000 cashback.
And you could get more help with a government grant. Octopus are experts and can advise on the schemes available to you and will even help you to apply.
Visit the Octopus Energy website for a quote and find out how much an air source heat pump might cost.
Selecting this button will take you to an external site.
Including the cost of fitting, an Octopus Energy air source heat pump can cost £500-£5500 including the government grant.
That means with the Green Living Reward, you could bring down the cost to a few thousand pounds and even free in a small number of homes.
In the unlikely event of something going wrong with your heat pump, you're in safe hands. Call the Octopus helpline and they’ll be able to assist you with any issues.
Octopus will tell you more about servicing and maintenance when they install your heat pump.
These are the most popular type of heat pump in the UK because of how efficient they are. They work by bringing warm air in from outside to heat water, radiators, and underfloor heating. A separate hot water tank is needed as they can't heat water instantly, like a gas boiler can.
Total costs are around £7,000 - £13,000 and might vary by supplier.
These heat pumps use an underground pipe to bring natural warmth up from the ground. The warmth is mixed with a special fluid and passed through a heat exchanger, ready to be used for hot water and to heat radiators and underfloor heating. And, as with air source heat pumps, a hot water tank is needed.
Total costs are around £14,000 - £19,000 and might vary by supplier.
This type of heat pump works a bit like an air conditioning unit in reverse, as it sucks in warm air from the outside and blows it inside. Air-to-air heat pumps can’t heat hot water, so they’re perfect for flats and other smaller places which don’t have any radiators or underfloor heating.
Total costs are around £1,600 - £3,100 and might vary by supplier.
This depends on a few things. Heat pumps work best in well-insulated homes, so it’s best to check this out before you start thinking about getting a heat pump. An easy way to do this is to find out your home’s Energy Performance Certificate (EPC) rating. If yours is a D or above and it says you have insulation, you should be good to go.
Most heat pumps use radiators to heat your home, just like boilers do. Sometimes, your existing radiators might be too small for a heat pump to work efficiently and will need replacing, but this isn’t always the case. A heat pump usually works well with existing underfloor heating too.
You’ll need some outside space for most heat pumps though. Around the size of a moped is usually enough for an air source heat pump. Ground source heat pumps take up more space than that, as they usually need a trench or borehole digging, plus a room inside for the operating system.

Help is available if you’re planning on upgrading or replacing your heating system with a new low-carbon one. But it’s different depending on where you live in the UK.
England and Wales:
The Boiler Upgrade Scheme (BUS) offers grants of up to £6,000 to replace gas, oil, and electric boilers and heating systems with lower carbon alternatives, including heat pumps and biomass boilers. Homes must meet certain EPC standards and other conditions to qualify. In Wales, the Nest scheme helps lower income families make their homes more energy efficient and better at saving water.
Home Energy Scotland offers grants of up to £5,000 for energy saving home improvements, like heating and insulation through the Warmer Homes Scotland programme. The scheme is funded by the Scottish Government to carry out improvements, such as wall and loft insulation, draught proofing, new boilers, and renewable energy projects with the aim of making homes warmer and cutting domestic energy bills.
