Air Source Heat Pumps & Ground Source Heat Pumps

  • Save money on heating your building and water
  • Use the natural heat in the air and the ground
  • Potential regular rebate through the Non-Domestic RHI scheme


Harness the natural heat in the air or the ground to keep your commercial building warm for less.

Air source heat pumps extract heat from the air and compress it, so it can be used in a warm air heating system or to heat radiators. Even on a cold day, there is still enough heat in the air.

Ground source heat pumps draw heat from the soil using a coil buried in the ground.

Both systems require very little electricity to run, and provide an environmentally-conscious way to heat your building or hot water. Many systems can also be reversed to provide cooling in summer.  


Air source or ground source?

If your building is on an existing industrial estate or trading estate, it’s likely an air source heat pump will be a better option for you, as it will be less disruptive to install. The unit/s will need to be sited outside your building.

Ground source heat pumps are great for new-builds, as they can be planned and installed in the ground as part of the overall construction programme.  

Existing buildings with surrounding land or grounds can also consider a ground source heat pump.

Our renewable energy consultants are experienced in designing heat pump systems, and will be happy to discuss options with you.

Energy efficiency considerations

It’s important to consider the insulation of your building before installing a heat pump.  Heat pumps tend to generate a lower level of constant heat, so if you have a ‘leaky’ building, you may not experience the full benefit. 

Our energy efficiency assessors can undertake an audit to find out if your business will benefit from energy efficiency improvements first.


Capital outlay and funding

With commercial installations, the cost and ROI of each system varies greatly, depending on the size of the system and building.  A discussion with our renewable energy consultants should be able to give you at least a ballpark figure; and of course we can undertake a full feasibility study and present you with cost and return on investment projections if you decide to take things further.   

Capital grants for renewable energy systems in the UK have been curtailed in recent years.  We can offer finance – take a look at our funding page for more information.

There is also a tax benefit to consider. Air source heat pumps and ground source heat pumps are included in the ECA (Enhanced Capital Allowance) scheme, which allows businesses to claim 100% first year capital allowance.  The product must be listed on the government’s Energy Technology List – but many products are included, and we work with all the major brands, so your choice won’t be limited.

Heat pump systems for non-domestic installations are charged at the full rate of VAT.


Government RHI rebate

The Non-Domestic Renewable Heat Incentive (RHI) scheme pays a sum for each unit of heat generated.  The Ofgem site shows the latest rates, which depend on the size and type of biomass system. Air-to-water systems and ground source systems are included, but not air-to-air systems at present.  

You can find more helpful links about the scheme on our funding page.
