Heat pumps are a great solution for heating and cooling in Wales. Unlike Northern parts of the UK, where homes experience colder temperatures throughout the year, Wales has a warmer climate than Northern Ireland and Scotland on average. It also rarely dips below 0°C, which means the region has an optimal temperature for heat pumps.
Yearly heating energy consumption | Heat pump running cost |
---|---|
7,312.5kWh | £760 to £1,185 |
11,212.5kWh | £1,065 to £1,410 |
16,575kWh | £1,475 to £2,435 |
Purchasing an air source model is far cheaper than paying a ground source heat pump cost in Wales, but the latter provides better efficiency and further decreases energy costs. Similarly, even within air source heat pumps, there are 2 categories: air to air heat pump and air to water heat pump models.
Air to air source heat pumps extract heat and pump it into the home, while air to water pumps also pump heat into a water receptacle. The latter can allow for underfloor heating or other hot water needs, but they are also more expensive.
Compared to gas boilers, heat pumps can incur lower costs, but this will depend on the COP (coefficient of performance) of your current system compared to that of a heat pump. The COP determines how efficient your heating system is. When the COP is above 3.0, heat pumps can be better than most gas boilers for saving costs.
Air source heat pumps tend to be between 2 and 4. Ground source heat pumps have the highest COP, often being around 4 to 5, which is 5 times better than boilers. Moreover, COP has a higher effect in Wales, allowing for better savings. Heat pumps in Scotland, for example, will operate in lower temperatures, which can increase the strain on the system.
However, one caveat to this is that the heat pump will work optimally and provide maximum savings when the home is properly insulated.
Heat pump outputs determine what price you will end up paying for a heat pump. The overall cost will range between £8,000 and £16,500 for a full installation. Heat pump size has a direct correlation with price and ability to heat up larger homes. Air to water heat pumps will generally require a higher output for larger homes.
House size | Air to air model size | Air to water model size | Supply cost | Total cost |
---|---|---|---|---|
1 bedroom | 7.5kW | 4kW | £4,000 - £8,000 | £8,000 - 11,500 |
2-3 bedrooms | 9.5kW | 13kW | £7,000 - £13,000 | £11,000 - £16,000 |
4-5 bedrooms | 11.5kW | 16kW | £9,500 - £15,500 | £14,500 - £16,500 |
Heat pumps for flats or single room homes can start at 4kW outputs. The average home will need between 9kW to 13kW heat pumps, which can start at £7,000 pre-installation.
Air source heat pump servicing tends to cost between £10 and £20 per month, depending on what needs to be cleaned up. This is roughly similar to the monthly service cost for other central heating systems. It can cost £150 to do basic electrical repairs, while it can cost £2,000 to replace the compressor.
Air source heat pump running costs will also depend on the COP of the system and the size of your home. The lowest running costs will be £625 if the homeowner buys a heat pump COP of 4 and has a smaller home.
COP | House size | Heating energy use (annual) | Running cost |
---|---|---|---|
3 | 1 to 2 bedrooms | 7,312.5kWh | £855 |
3 | 2 to 3 bedrooms | 11,212.5kWh | £1,205 |
3 | 3 to 4 bedrooms | 16,575kWh | £1,700 |
3.5 | 1 to 2 bedrooms | 7,312.5kWh | £760 |
3.5 | 2 to 3 bedrooms | 11,212.5kWh | £1,065 |
3.5 | 3 to 4 bedrooms | 16,575kWh | £1,475 |
4 | 1 to 2 bedrooms | 7,312.5kWh | £625 |
4 | 2 to 3 bedrooms | 11,212.5kWh | £870 |
4 | 3 to 4 bedrooms | 16,575kWh | £1,200 |

A heat pump grant can be a great way to cover the costs, especially if you live in a low-income household. Heat pump grants in Wales include:
Grant name | Savings | Availability |
---|---|---|
ECO4 | Up to £10,000 | March 2026 |
Warm Homes Nest Scheme | Varies based on property requirements | Indefinite end date |
Boiler Upgrade Scheme | £7,500 | April 2028 |
0% VAT | Between £480 to £2,800 | March 2027 |
The eligibility criteria for each grant can also vary:
Air source heat pump savings £290 to £650 depending on the system you’re replacing.
Heating system type | Annual savings |
---|---|
Old (G-rated) gas boiler | £290 |
Old electric storage heaters | £1,200 |
New electric storage heaters | £700 |
Old (G-rated) oil boiler | £280 |
Old (G-rated) LPG boiler | £650 |
New (A-rated) LPG boiler | £260 |
Coal | £650 |
Due to the price of electricity, many less efficient fossil-fuel systems may provide better savings than lower-power air source heat pumps. However, air source heat pumps are by far the best option for those living off the gas grid.
Pros:
Cons:
Yes. Heat pumps can be worth it in Wales, especially if you have an ageing boiler. To achieve better running costs than most gas boilers, a heat pump will need to have a COP above 3. While heat pumps can be a big investment, there are many grants that can help mitigate this. Furthermore, prices for heat pumps are lower than ever, thanks to the 0% VAT scheme.
Welsh households that are off the gas grid can benefit from air source heat pumps in particular. They provide far better savings than other electric solutions and can be hooked up to other renewable energy sources. Heat pumps, if chosen correctly can be a great addition to any household in Wales.
If all this has swayed you into a purchase, you’ll probably be looking for more information or a heat pump quote so you can understand prices. For that, you’ll need to find a reliable installer which can take hours of research and calling up companies if done on your own. If you’d rather skip all the hassle, we’ve got a service that can provide you with up to 4 free, non-binding quotes from trustworthy professionals in your area.
