For organisations across the North East and wider UK, choosing the right heating solution can make a significant difference to energy costs and sustainability goals. Heat pumps are quickly becoming one of the most efficient and eco-friendly options. But what is the real difference between ground source heat pumps and air source heat pumps, and which one is right for your business or site?
Here is a simple guide to help you understand the options before planning your heat pump installation.
How Do Heat Pumps Work?
Both systems operate on the same principle. They use electricity to extract heat from the environment and transfer it into your building. This method is much more efficient than traditional gas or oil systems and helps reduce carbon emissions as highlighted in a recent study by Oxford University which found that heat pumps are 2 -3 times more efficient even intemperatures below zero degrees Celsius.
For larger sites such as hospitals, offices, or schools, heat pumps provide consistent heating and may make your organisation eligible for government funding through initiatives such as the Public Sector Decarbonisation Scheme.
What Are the Main Differences Between Ground and Air Source Heat Pumps?
1. Heat Source
Ground source heat pumps collect warmth from the ground through a network of buried pipes. The ground maintains a stable temperature throughout the year, ensuring reliable, efficient heating.
Air source heat pumps extract heat from the outside air using an external fan unit. They are easier to install and are well suited to urban locations, although performance can decrease slightly during very cold weather.
2. Efficiency
Ground source systems typically achieve a coefficient of performance (COP) of 2–5, which means up to five units of heat are generated for every unit of electricity used.
Air source systems generally have a COP of 2–4, which still provides high efficiency suitable for most UK climates.
3. Installation and Costs
Ground source heat pump installation involves trenching or drilling for the underground loops. This process is more complex and expensive, usually costing between £10,000 and £30,000, but it provides excellent long-term savings.
Air source heat pump installation is faster and more affordable, typically ranging from £4,000 to £8,000 per unit. It is ideal for smaller sites or buildings with limited space.
4. Maintenance
Both systems are low-maintenance and environmentally friendly. Ground source systems require very little attention once installed, while air source units need periodic servicing of the outdoor component to maintain efficiency.
Which Heat Pump Is Better for My Business or Organisation?
Organisations should consider ground source heat pumps if there is available outdoor space and a priority for maximum efficiency, reliability, and long-term value. These systems suit large or rural sites, including hospitals or manufacturing facilities.
Air source heat pumps are best for urban sites, smaller properties, or situations requiring quicker installation and lower upfront costs.
It is advisable to consult an experienced M&E contractor to assess your site. They can recommend the most effective heat pump installation based on available space, energy requirements, and budget.

FAQ – Heat Pump Installation
1. Are heat pumps suitable for older buildings?
Yes. Both ground source and air source heat pumps can be installed in older properties, although some upgrades to insulation or radiators may be needed to ensure maximum efficiency.
2. How long does a heat pump installation take?
Installation time varies depending on the system and site size. Air source heat pumps are typically quicker, taking a few days/weeks, while ground source heat pumps may take several weeks due to trenching or drilling requirements.
3. Can heat pumps really reduce energy costs?
Absolutely. Heat pumps are much more efficient than traditional heating systems and can significantly lower energy bills while reducing carbon emissions.
4. Do heat pumps require a lot of maintenance?
No. Ground source heat pumps need minimal upkeep once installed, and air source heat pumps require only occasional servicing of the outdoor unit to maintain efficiency.
5. Are there grants or funding available for heat pump installation?
Yes. In the UK, schemes such as the Public Sector Decarbonisation Scheme provide funding for eligible organisations, particularly hospitals, schools, and public buildings.
