What is a heat pump?
A heat pump heats your home using electricity. It works like a fridge in reverse, taking heat from the air or ground (even when it’s very cold outside). It increases it to a higher temperature and transfers it to your home to provide heating and hot water. A heat pump can warm your home and water even on the coldest days.
An air source heat pump unit is fixed on the outside of a home or property. A ground source heat pump unit is fitted outside of your home and property. There are more and more heat pumps being installed in the UK, with 100,000 being installed in 2024, that’s 55% more than in 2023.

Financial help for your heat pump
Boiler Upgrade Scheme grant
Most homeowners in Wales are eligible for the Boiler Upgrade Scheme grant to help cover the costs of installing a heat pump. To qualify, you’ll need to meet the following criteria:
You own the property – whether it’s your main home or a second property.
You’re replacing an existing fossil fuel heating system – gas, oil, electric or LPG.
Your property has a valid Energy Performance Certificate (EPC).
The property is in Wales or England.
Your installer will check if you’re eligible and whether you need any updates to your home to get the best out of your heat pump. They’ll then make an application to the Boiler Upgrade Scheme on your behalf via the Ofgem website – saving you the hassle.
Interest free loans
Homeowners in Wales can also access finance from Green Homes Wales.
It offers support from a fully funded home assessment by an independent expert who will recommend improvements to your home, through to interest free loans to help with costs.
Green Homes Wales works alongside the Boiler Upgrade Scheme to give you accessible finance if the installation costs are more than the grant that’s available.
Several energy suppliers can offer finance deals, such as 0% finance and low interest.
You may also be able to get cashback through your mortgage, some banks offer up to £2,000 cashback for heat pump installations through approved schemes. It's worth checking with yours.
0% VAT
Heat pump installations benefit from being exempt from VAT.
If you’ve already decided to get a heat pump, find a trusted installer near you to get quotes and a home assessment.

What a heat pump means for your home
Air source heat pump
You’ll need a small space outside your home for a fan unit which typically ranges from 1 to 1.5m in height. This can sometimes need planning permission – you can check if you’re property does here.
Ground source heat pump
You’ll need a larger space outside for pipes to be buried in an array or a borehole. These heat pumps range in height from as little as 0.5m to around 1.7m depending on the model.
Sound
A sound assessment is usually done during the installation process. Modern heat pumps are generally found to be relatively quiet, with noise similar to a fridge or a boiler.
Inside your home
If you don’t have one already, your heat pump will need a hot water storage unit like a cylinder to give you hot water. Installers may recommend upgrading radiators to maximise the system efficiency. Where needed, these changes are generally included in the installation quote and can be covered by the grant.
What to expect when installing a heat pump
Installation can take between 2-5 days.
Disruption can be minimal, far less than rewiring or replacing your whole heating system.
You’ll have hot water throughout, except for a short switch-over period of a few hours.
If you’re already planning upgrades or renovations to your home, switching to a heat pump at the same time could help limit future disruption to your home.

Using a heat pump
Your heat pump will work alongside a thermostat to maintain a comfortable temperature in your home. It will automatically adjust how hard the heat pump works according to how cold it is outside.
If you have a smart meter installed, some energy suppliers offer ‘time-of-use’ tariffs with cheaper electricity during off-peak hours.
If you have solar panels or a home battery, the electricity from your panels may provide enough power for your heat pump during the day or stored in your battery. This creates a smart system using homegrown energy to make extra savings on your bills.

*Costs and savings associated with smart tariffs require a smart meter to be installed and vary depending on the tariff; how often and when you heat your home; the type, size and energy efficiency of your property; and the efficiency of your heat pump, among other factors. The figures above are based on dynamic simulation modelling of an average 3-bed detached house with insulated cavity walls and a heat pump with a seasonal performance factor of 3.13. Savings are based on Octopus Cosy tariff prices and the energy price cap from the period between July 2023 - July 2024 and assume no gas standing charge. As energy prices and tariff rates change, so will estimated costs and savings.
