It’s well known that a ground source heat pump system can make your home more efficient, lowering your energy bills as a result, but they also have many more benefits:
- Normally require very little maintenance
- You can receive government payments through the Renewable Heat Incentive (RHI)
- Could lower the carbon dioxide emissions of your home by 2 – 8 tonnes each year
- Quiet operation
- Longer lifetime than traditional heating systems
- Potential to increase the value of your home

What is the Renewable Heat Incentive?
Launched in 2014, the Renewable Heat Incentive (RHI) is a government initiative to encourage homeowners to invest in renewable technologies. Through the scheme, you could receive payments every quarter over 7 years should you have a renewable heating technology installed.
The scheme is part of a wider initiative to reduce the carbon emissions of the UK and meet renewable energy targets.

Things to Consider Before Installing a Ground Source Heat Pump System
While there are many benefits, it’s worth considering the potential downsides before investing in a ground source heat pump system.
You’ll only feel the full benefits of a ground source heat pump system if your home is well insulated, this is because they operate at low temperatures. Due to this, it’s worth remembering that radiators are only effective at high temperatures so this system is better suited to homes with underfloor heating.
One of the big plus points of having a ground source heat pump installed is the potential savings on your energy bills. If you’re looking to replace a gas system then you’re unlikely to see the same sort of savings as someone replacing an electric or coal powered heating system.
Finally, the system requires underground pipes in the garden which means that you’ll need to consider if your garden is big enough and whether digging machinery can gain access.
How Much do Ground Source Heat Pumps Cost?
A ground source heat pump is likely to cost somewhere between £8,000 and £12,000 but the price will vary depending on the model and manufacturer. You can find out the best ground source heat pump manufacturers with our guide.
The cost of installing a ground source heat pump system will differ depending on who you hire to carry out the work but the Energy Saving Trust estimate the total installation costs to fall between £10,000-£18,000. To help lower these costs, the best time to install a ground source heat pump system is when you have other building work taking place, so if you’re planning a renovation that’s an ideal time.
