Heat Pumps in England: Greening the Nation
Creating an energy efficient home is an increasingly possible and attainable task. With the positive trend towards a more sustainable way of living, the possibilities are endless and more and more affordable.
Some of the many benefits of installing heat pumps in England are:
- the price of heat pumps is partially covered by grants that help cover costs in England
- an efficient source of renewable and clean energy
- installation possible countrywide, from London to Liverpool
- results in noticeable savings on your utility bills
A heat pump moves heat from one location to another while using a minimal amount of energy. Heat pumps in England enable users to reduce their carbon footprint while heating their homes.

How Much Do Heat Pumps Cost in England?
Are heat pumps in England worth the investment? Both air source and ground source heat pumps are viable options across England, both in terms of heat pump cost and running costs.
Air source heat pump prices and ground source heat pump prices vary based on many factors, such as the size of the home, how well insulated it is, and what room temperature you are hoping to maintain.

Comparing Price and Efficiency of Heat Pumps in England
The total installation price for air source heat pumps in England ranges from £7,000 to £14,000. In comparison, the Energy Saving Trust estimates that ground source heat pumps cost between £13,000-£20,000 to install and approximately £655 a year to run.
Although ground source heat pumps in England cost significantly more, they are also more efficient at heating your home.
The cost structure breakdown for air source heat pumps (ASHP) and ground source heat pumps in England is slightly different. When comparing a 12kW air source system with a 12kW vertical borehole ground source system, the following breakdown is visible:
Air source systems have a higher equipment cost proportion due to the fact that the installation is a lot simpler than for a ground source heat pump (GSHP), which has a higher non-equipment cost. Ground source heat pumps require additional drilling, boreholes, ground work, as well as a more advanced and complex design process.
Grants for Heat Pumps in England
Green energy grants and incentives are available across England to help cover the costs of heat pump installation. The grants are valid in England, Wales, and Scotland.
In order to be eligible for the domestic Renewable Heat Incentive (RHI) for heat pumps in England, several criteria must be met. These include:
- Energy Performance Certificate (EPC) that is less than 24 months old
- Both air and ground source require a liquid to provide space heating
- Both air and ground source heat pumps in England must have a minimum SPF of 2.5
- Both air and ground source must use a compressor driven by electricity
- Renewable technology must only heat a single domestic property
- “Dwelling type” must be a house, a bungalow, a maisonette or a flat (or similar)
- You must either own or occupy the property the renewable technology heats.
The following table gives a breakdown of the compensation received when installing heat pumps in England:
|Updated August 2016*||GSHP||ASHP|
|Renewable Heat Incentive Payment (£/year) - April 2016 to present||£2,590 to £4,005||£1,055 to £1,420|
|Total Costs||£13,000 to £20,000||£7,000 to £11,000|
|Tariff Rates (p/kWh) quarterly payments over seven years||19.33p||7.51p|
Which Heat Pump is the Best Solution for You?
Heat pumps can be installed in all regions of England. The setup of the heat pump varies, as horizontal ground source heat pumps may only be viable in rural regions, and vertical ground source heat pumps are more common in urban areas where there is less space.
Apart from installation of heat pumps in England, very minimal maintenance is required with heat pumps. Air and ground source heat pumps are also called “fit and forget” technologies, because once they are installed, very little effort or servicing is required to maintain them.
Air Source Installation
Air source heat pumps use a natural heat source, the air. The air source heat pump system absorbs air from outside and converts it into heat for your home. The air can be used as heat for an underfloor heating system, for radiators, warm air convectors, or to supply a home with hot water.
For air source heat pumps in England, you will require space outside your home where a unit can be attached to the wall or placed on the ground. The units are similar in size and appearance to air conditioning units.
The exact size of the heat pump will depend on your heating demand and the insulation of your home, as the larger and less insulated the home, the more heat required and therefore a larger unit will be needed. The unit will also require space around it in order to get the appropriate air flow.
Install Ground Source Heat Pumps in England
For ground source heat pumps, vertical systems require less space than horizontal systems in the UK. Horizontal trenches are approximately 1-2 metres deep, and take up a larger area of land so they are more common in rural areas where space is not an issue.
Since underground temperatures remain constant year round (11 degrees Celsius in England), you get minimal temperature fluctuations when compared to the air temperature, resulting in a more efficient system.
Before deciding between air source or ground source heat pumps in England, you need to consider whether you can afford the additional expenses of the GSHP for the increased efficiency.
How Efficient are Heat Pumps in England
Air source heat pumps face more temperature fluctuations, meaning the pump works harder in colder temperatures and works less when the air is warmer, that results in a varying coefficient of performance (COP).
To compare different heat pumps in England, it is therefore best to use the seasonal performance factor (SPF), the ratio of heat delivered by the heat pump compared to the electricity supplied to the compressor throughout the heating season.
When looking at an air source heat pumps in England, the typical seasonal performance factor is 2.5 – 2.8. During the winter, the COP of heat pumps in England will likely fall well below 2.5, and during summer months, it may be as high as 4.
Ground source heat pumps are more efficient, therefore you can expect a typical seasonal performance factor of about 4.
