Ground Source Heat Pump (GSHP) Installation Sussex

We are experts in ground source heat pump (GSHP) installation, repair, and servicing across Sussex and Surrey. Heat pumps are a low-carbon alternative to traditional heating and are fast becoming the first choice for home heating.

What Are Ground Source Heat Pumps?

Ground source heat pumps are revolutionising how we heard our homes and they will play a big role in helping the UK reach its Net Zero by 2050 goal. They are energy-efficient systems that harness the natural heat stored in the ground to provide heating and hot water for residential and commercial buildings. These systems use the constant temperature of the earth to heat spaces efficiently and sustainably.

How Do Ground Source Heat Pumps Work?

Ground source heat pumps work by harnessing the natural heat stored in the ground. They use a system of buried pipes called a ground loop to extract heat from the earth. Inside the ground loop, there is a water-based solution called thermal transfer fluid (TTF) that absorbs the heat from the ground. This solution then carries the heat to the heat pump unit in the building.

Once inside the heat pump unit, the heat is amplified and transferred to either the building’s heating system or its domestic hot water supply. During the cooling mode, the process is reversed, and the heat pump removes heat from the building and dissipates it back into the ground. This cycle allows ground source heat pumps to efficiently provide heating and cooling for buildings while using the earth’s natural heat.

Available Ground Source Heat Pump Grants

There are various grants and incentives available to support the installation of ground source heat pumps. You can get thousands of pounds from ground source heat pump grants from the government towards installing a new heating system in a bid to reach the Net Zero by 2050 goal. Our knowledgeable team can provide guidance on available grants in your area, helping you make the most of financial assistance programs and maximise your savings.

As of April 2024, the UK government is running the Boiler Upgrade Schema (BUS) which provides a £7,500 grant against the cost of a ground source heat pump.

Pros and Cons of Ground Source Heat Pumps

Ground source heat pumps offer numerous advantages, but it’s essential to consider both the pros and cons before deciding on their installation.


  • Energy efficiency – Ground source heat pumps are highly energy-efficient, providing significant savings on heating costs compared to traditional heating methods.
  • Reduced carbon footprint – By using renewable heat from the ground, these systems help reduce greenhouse gas emissions, contributing to a greener environment and positively impacting your carbon footprint.
  • Long lifespan – Ground source heat pumps have a long operational lifespan, often exceeding 20 years providing reliable heating for an extended period.
  • Versatile heating – These systems can be used for both heating and cooling purposes, offering year-round comfort in various climates and seasons.


  • Initial installation cost – The upfront cost of installing a ground source heat pump system can be higher compared to traditional heating systems. However, the long-term energy savings can offset this initial investment.
  • Land or drilling requirements – Ground source heat pumps require sufficient land space for the installation of the ground loop or may involve drilling boreholes. The likelihood and cost of installing the system can be influenced by limitations in available space or geological factors.
  • Electricity dependency – While ground source heat pumps are energy-efficient, they still rely on electricity to operate. It’s therefore important to consider the electricity usage when assessing the energy consumption and overall cost of using the system.

Will a Ground Source Heat Pump Save Me Money on My Energy Bills?

Installing a ground source heat pump has the potential to significantly reduce your energy bills. As it uses energy from the ground rather than fossil fuels, it can provide efficient heating at a lower operating cost. Additionally, ground source heat pump installations may qualify for government grants which can increase your savings even further.

Frequently Asked Questions

Can ground source heat pumps provide both heating and cooling?

Ground source heat pumps are designed to provide both heating and cooling for residential and commercial buildings. They can keep you warm during the colder months by extracting heat from the ground and pumping it into your building. Then, when the weather gets hot, they reverse the process to remove heat from your space back into the ground to cool it down.

How long does a ground source heat pump system typically last?

A well-maintained ground source heat pump system can typically last for more than 20 years. The underground piping system can last even longer, with a lifespan of 50 years or more.

What is the difference between a ground loop and a ground source heat pump borehole?

A ground loop refers to the network of buried pipes through which a ground source heat pump extracts heat. This loop can be installed horizontally in trenches if sufficient land space is available, or vertically by drilling boreholes into the ground. The main difference is the orientation and depth of the pipe installation. Boreholes involve drilling deep into the ground to access the heat source, whereas ground loops are laid in shallow trenches.

How much space is required for a ground source heat pump installation?

Ground source heat pump installations require more space than air source heat pumps. Horizontal systems need approximately 700 square meters for the pipe network in trenches, while vertical systems require space for a drilling rig and have smaller boreholes placed 5-6 meters apart. Space requirements vary based on factors like property size, soil conditions, and heating/cooling needs. Please get in touch with us to discuss your space requirements in more detail.

Do ground source heat pumps require planning permission?

In most cases, you won’t need planning permission for a ground source heat pump installation. However, it’s always a good idea to check local regulations.
