What Is A Ground Source Heat Pump?

A ground source heat pump is a renewable heating system designed to extract heat from the ground for use in your home. They work by having pipes installed underground, either as vertical closed loop systems in boreholes or as a horizontal ground loop system. These pipes are filled with a refrigerant liquid that is capable of extracting heat from the ground temperature.

This heat is then heated further through compression before being sent to a heat exchanger which can transfer heat energy to water, this can then be used as hot water in your home and in your radiators/underfloor heating system. Getting your home heating from the ground temperature makes ground source heat pumps a form of renewable energy system that brings a range of benefits.

How Much Do Ground Source Heat Pumps Cost?

The average cost of ground source heat pumps varies significantly because the installation costs can have a huge impact on the final overall cost.

Installing ground source heat pumps is an incredibly involved process that involves a lot of ground prep work before the pipes can be installed, and then you’ll need to factor in the indoor heat pump unit installation cost on top of that.

The actual heat pump itself can also be expensive, and there are plenty of different makes and models to choose from, all with different specs that increase or decrease the cost accordingly.

Essentially, the final cost will vary significantly but you can expect to pay:

  • £7,000 – £32,500 (with grant support)
  • £14,500 – £40,000 (without grant support)

The good thing is, even with these high initial costs, you’ll make savings on your energy bills which will mean you pay less each year. With your heat pump relying on natural heat to warm your home and hot water, your heat pump system will eventually pay for itself in energy bill savings.

Ground Source Heat Pump Benefits


Energy efficient heating:

Heat pump efficiency can reach between 300 and 500% with ease. That means for every 1kW of electrical energy used to power the ground source heat pumps, 3-5kW of heat energy is produced for your home.

Reduced carbon emissions:

If your carbon footprint is a concern for you, then heat pumps are an excellent alternative to the traditional gas boiler that is likely heating your home at the moment. Ground and air temperature is renewable energy, which reduces carbon emissions considerably.

Government grant support:

Whilst initial installation costs for ground source heat pumps can be expensive, there are government grants for ground source heat pumps available such as the Boiler Upgrade Scheme which offers £7,500 in support towards either a ground source or air source heat pump, helping reduce these costs.

Cost savings:

If you’re switching from old, inefficient heating systems then you can make serious savings each year on your energy bills. These savings can help thousands of UK homeowners with managing their finances during difficult economic times.

The above are just some of the many benefits of ground source heat pumps. In short, though, if you have an older heating system that needs upgrading, heat pumps are an excellent option for many homes.

Are There Any Ground Source Heat Pump Drawbacks?

Whilst ground source heat pumps are an excellent example of an electric heating system that’s capable of transforming the way you heat your home, there are certain drawbacks you need to be aware of before rushing into any decision:

  • High upfront cost – even with a government grant the cost is still high and can be too high for some households to comfortably invest in this type of heating system.
  • Installation – the installation can be time-consuming and incredibly invasive with holes needing to be dug to absorb heat from underground for your home.
  • More suitable for new builds – because of the inconvenience of the installation it’s often easier to install a ground source heat pump at a new build property, rather than retrofitting one at an older property. 

There are drawbacks to installing ground source heat pumps, but the pros usually outweigh the cons for most people in the UK.

Are Ground Source Heat Pumps Worth It?

Whether ground-source heat pumps are right for you or not depends on the long-term nature of the investment you’re making.

When you switch from an older, inefficient heating system, you’ll notice huge savings on your energy bills each month, which really makes the purchasing of a new ground source heat pump that much more of a no-brainer. However, if you switch from a newer, A-rated, more efficient gas boiler, then you could actually only end up saving a small amount on your energy bills.

With electricity and gas prices in April 2024 from Energy Saving Trust, it’s estimated that switching to ground source heat pumps from an A rated gas boiler could only save you a total of £50 per year. Whilst it’s still a saving, the cost of installing ground source heat pumps means that your savings won’t ever cover the cost of the heating system itself – but in most other cases it will.

Generally speaking, though, a ground source heat pump is a worthy investment that pays for itself and will save you significant money on your energy bills annually.

Traditional Boilers

Traditional boilers run on gas which is costly, making them an expensive option for households to run.

Air Source Heat Pumps

Heat pumps are a highly efficient, much greener alternative to other forms of heating like gas boilers.

Do Ground Source Heat Pumps Use A Lot Of Electricity?

Ground source heat pumps obviously use more electricity than your current gas boiler, because gas boilers don’t use any electricity at all. So, yes, in comparison they use a lot of electricity but the real question shouldn’t be about electricity. Instead, it’s important to look at the amount of energy needed to power the heating system.

Gas boilers will use around 11,500 kWh of energy each year – but a ground source heat pump will only use around 2,500 kWh of energy each year to achieve the same output – that’s around 1/5.

A ground source heat pump will use significantly less energy than a gas boiler will to achieve the same results, so whilst you’ll be using more electricity, you’ll be using significantly less energy.

Frequently Asked Questions

Ground source heat pumps take longer to install than their air source heat pump counterparts, largely because of the prep work involved.

Installing the new ground source heat pump unit will typically only take a day or so, but the installation of the entire system can take anywhere from 3-4 days to a week. That’s because the boreholes for the pipes will need to be dug to the correct depth and the units will need to be installed in the appropriate places to ensure they work optimally.

Ground conditions play a large part in exactly how long it will take to fully install your ground source system, so when you find an installer through us, they’ll be able to give you a much more accurate timeframe alongside an accurate quote for the work.

If you choose to install ground source heat pumps at your property, then you should find that they’re considered to be within permitted development for most UK homes. That means planning permission is NOT usually required.

However, this only applies to the first heat pump you install on your property and so long as the groundwork (digging up the ground to lay down the pipes) doesn’t affect more than 0.5 hectares – around 1.24 acres. Most systems will only require one heat pump and the pipework will usually affect far less ground than 0.5 hectares, so you won’t need planning permission.

If your system is set to exceed the limits stated above, then your heat pump installer can help you with the planning process and explain what your next steps ought to be.

Before choosing which ground source heat pump to install at your home, you’ll want to get a better idea about the big brands so you know who enjoys an excellent reputation in the industry for high-quality products.

Below are some of the biggest heat pump brands with the best reputations:

These names have been developing technology for heat pumps for years and enjoy a reputation as some of the leading manufacturers of heat pumps which many UK homes are now benefiting from.

Whilst it isn’t certain which brand of heat pump will be best suited to your home, you can expect our heat pump installer partners to offer the best brands and competitive prices.

A ground source heat pump is usually best installed in newer build properties which have had heating systems installed specifically to accommodate a heat pump. That’s because ground source heat pumps require either large radiators or underfloor heating to effectively emit enough heat for the home to maintain a comfortable temperature.

However, if you don’t live in a new build, you can still benefit from a ground source heat pump at home, you’ll simply need to update your radiators or switch to underfloor heating to ensure your home is as warm as possible.

Despite the cold temperatures outside in the UK during winter, ground-source heat pumps still work perfectly well. In fact, the outside air temperature may feel cold to us, but the heat that’s still stored underground is sufficient all year round to warm your home and hot water.

Ground-source heat pumps are actually more efficient in winter than air-source heat pumps because temperatures underground remain more consistent and generally have a constant temperature year-round.

That means ground-source heat pumps need to use less electrical energy to achieve the same heat output as air-source heat pumps when the weather is cooler during winter.

A closed-loop system and open-loop system will achieve the same results for your home, but they work slightly differently.

Closed loop systems have a sealed pipe network with a fluid that constantly circulates through the system, being warmed by the underground temperatures, and compressed to further increase the temperature, before that heat is exchanged and used to heat hot water for your radiators and use in your home. The cycle then repeats itself.

Open loop systems work slightly differently. Instead of a fluid being constantly present in sealed pipework, there is an abstraction borehole designed to take up groundwater which is already warmer thanks to the underground temperatures being higher. This groundwater is then taken through the same compression and heat exchanger processes to heat up water for use in your home’s hot water system and radiators. This groundwater is then released back underground or at a nearby water source and new groundwater is taken up to continue the cycle.

You might be wondering how ground source heat pumps manage to enjoy efficiencies of between 300 and 500% – how can a device produce more energy than what’s put in? Well, the heat energy that is used by the heat pump system is already naturally present in the ground, so it doesn’t produce more energy, it simply makes use of natural heat energy – renewable energy.

Where 1kW of electrical energy is used to power the heat pump and 4kW of heat energy is the output, 3kW of natural heat energy is utilised from the ground, allowing heat pumps to achieve such impressive efficiencies.

This depends on if you’re using a vertical or horizontal ground source heat pump.

For vertical boreholes, you only need a diameter of around 20 cm, and just enough space in your garden for the machinery to access the site to dig a deep enough hole to satisfy the system requirements.

Horizontal systems, on the other hand, will need around 700 square metres of space in order to install the pipework required. This is obviously a large job and can be quite intrusive for your home, so typically vertical boreholes are preferred where possible to reduce the installation time and, ultimately, the costs involved.

No, not every property in the UK will be better off with a ground source heat pump, and not every property in the UK will have space for one either.

If a horizontal system proves more effective for your home, but you only have a small garden, then obviously you can’t install one. Even with vertical systems larger gardens help with installation, and some UK gardens are so small that neither system is appropriate because the machinery required to install the system simply can’t access the site. 

Properties with poor insulation may also find that the energy savings they may have expected by switching to a ground source heat pump might be less than initially expected. Sometimes, it can actually prove less cost effective to switch to a ground source heating system – in these instances, an air source heat pump may be more effective.

On average ground source heat pumps cost between £500 and £1,200 per year to run – depending on your current heating bills each year, you may find that this is a saving or more expensive.

If it’s more expensive, it will likely be only slightly more so and is probably because you’re switching from a modern A+ energy-efficient gas boiler.

There are other factors to consider here, too. If the system does result in slightly higher annual heating bills, then it’s important to remember additional benefits like the reduction of your household carbon emissions to help decide if making the switch is still worth it to you.

The main difference between air and ground-source heat pumps is where they source their heat from. Ground source heat pumps, as we’ve covered, source their heat from underground, where temperatures remain relatively consistent throughout the year.

Air-source heat pumps, however, source their heat from the air. This may seem counterintuitive, as you might assume that when it’s cold outside an air source heat pump system would be unable to function and warm your home effectively. This isn’t the case.

Although the temperatures outside might feel too cold for an air heat pump to be able to heat your home, there is always heat to be extracted and compressed to warm your home – more energy is simply required to do so here. Air source pumps can operate in conditions as low as -20 degrees celsius, which we rarely reach in the UK, and when we do, it’s often in more remote areas in Scotland and the like.

Ground source and water source heat pumps differ again, but crucially it has to do with where they source their heat. Ground source heat pumps source their heat from the ground, and water sources from the water.

With a water source pump, you’ll need to live by a large body of water where pipes filled with a refrigerant-like fluid can be placed. Temperatures in flowing water or deep in still water remain fairly consistent year-round too, so can be a great way to reliably get heat to be compressed and used for your home.

Yes, so long as you purchase a ground source heat pump with reverse cycle capabilities. Here, the heat pump will work in reverse, instead of compressing heat to make it warmer, the cooler temperatures underground will be used to provide space cooling for your home, essentially acting as an air conditioning unit, making your home cooler.

Almost universally the answer to this question is yes. Investing in a ground source heat pump will usually mean you’ll see significant annual energy bill savings that mean your heat pump will essentially pay for itself over the years.

Given the savings, the reduction in your household carbon footprint and the efficiency of the heating system, ground-source heat pumps are usually a great option for every home.

If you’re unsure if your home is appropriate for a heat pump, work with us to find a quote today, and our installation partner will be able to discuss your options with you – including if an air source heat pump might be a better option for your home.

We had an Ideal Logic 2 Combi boiler fitted on 29/06/23 with Fixx. Craig the Engineer arrived bright and early after a call to say he would be there in 30 minutes. He was very efficient and finished by mid afternoon before running through all the wireless thermostat details before leaving. Found the company extremely helpful with any questions I asked, great company to do business with and would recommend highly.

Extremely impressed with Fixx and everyone there that I dealt with. They discussed all the requirements for a new under sink water heater for my flat to supply the kitchen sink and bathroom sink in the next room, as well as connections for a dishwasher and washing machinke. They provided a quote very quickly and the whole thing was installed just a few days later. Very neat setup, all ready for the kitchen fitter to complete the worktop and hook up the taps to the sink (see photos). I would 100% use Fixx again - I'm a very satisfied customer.

The two gentlemen from Fixx did a fabulous job removing my Boiler Mate 2000 and replacing it with an unvented cylinder. Everything at each stage was explained to me and they worked extremely hard to achieve a fantastic result. I won’t hesitate to contact them in the future if and when I need a new boiler and would 100% recommend Fixx to anyone.
