About us

We are the focal point of the heat pump installation industry in the UK

It is the voice for the lowest running cost, lowest carbon, heating and cooling system for domestic and commercial buildings and heat sharing networks. Heat pump technology is not based on combustion and emits no gases of any sort on site.

Bringing knowledge
& experience together

As a trade association the GSHPA brings together over
160 members and interested parties from across the
heat pump installation industry to develop a strong,
dynamic and sustainable environment for heating and
cooling systems that are based on heat capture, heat
storage and heat transfer, including heat sharing
networks and demand side management.

Our Vision

At the GSHPA, we advocate the value of a combustion-free approach to meeting heating and cooling needs.

Ground Source Energy

Ground source energy at all scales reduces users’ bills, carbon
emissions and emissions of all noxious gases.

Energy Services

Such as a temporary reduction or increase in electricity demand, can
allow consumers to participate in the electricity system while reducing
the need for new energy infrastructure by better resource management.

District Heating

The supply of heat to homes and businesses through a network of
heat sharing pipes, can reduce heating bills in urban areas, and give
communities more control over their heating and cooling needs and
the timing of the supply of those needs.

Affordable Low Carbon Heating & Cooling

There is now a silver bullet which can deliver an affordable, secure and
low carbon heating and cooling system. By thinking about consumers
first, we can use a range of options to find the right solutions for the
right people in the right place at the right time.

Our Aims

The GSHPA aims to electrify heat. We act as an advocate for our members by engaging with Government and key decision makers to support cost effective and efficient solutions to industry, businesses and householders by:

  • Developing a policy which puts the energy user’s needs first
  • Delivering a local, low carbon heating system at lowest cost
  • Ensuring an understanding of heating and cooling, which
    makes up half of our energy use
  • Taking an integrated and ‘internet of heat’ approach
  • Helping users manage energy demand to limit the need for
    new generation capacity
  • Strengthening the ground source energy industry’s reputation
    through publishing GSHP Standards and best practice

Edward Thompson

Vice Chair

Edward Thompson joined Mark Hewitt, an architect who has specialised in energy-efficient buildings for many years, and Andy Ford, a mechanical services engineer and founding partner of Fulcrum Consulting, who jointly developed the ideas that led to Interseasonal Heat Transfer, Thermal Banks and solar assisted ground source energy. This novel ICAX approach to harnessing ground source energy has provided innovative systems for supermarkets, schools, community centres and for maintaining roads free of ice and snow.

The current challenges for GSHPA members are to demonstrate the potential for GSHPs in District Heating, to learn how to exploit the opportunities presented by Demand Side Response – as well as to persuade BEIS to take the actions it knows it should to promote ground source energy as the key route to reducing carbon emissions from heating and cooling.

After reading science at Oxford, qualifying as a Chartered Accountant and working in finance, computing and venture capital Edward has specialised in helping young companies with new ventures. He is a director of the Ground Source Heat Pump Association and Vice Chair of the Council.

Andrea Ellison


Andrea Ellison is a Director and Treasurer of GSHPA as well as Chair of the Marketing Group, Chair of the Drillers Action Group and an active member of the Education and Training Committee.

Andrea joined GSHPA in 2013 and was voted onto the Council of the GSHPA in 2014. She has been actively involved in the promotion of heat pumps and the Association and, with experience in finance, company law, education- which includes operating a private school – and a number of commercial organisations Andrea has brought a wide range of skills to the GSHPA as well as the drive to promote the use of heat pumps to politicians, installers and potential users.

She not only attends shows and events for GSHPA, but she has produced an ‘Off the Shelf’ scheme of work for schools for children from ages 5 to 16 which is available free of charge for schools throughout the UK. She is also directly involved with producing Schemes for various schools and colleges.

In her roles within the standing groups of Marketing, Education and Drillers Action she has always focused on ensuring quality is key and the launch of the GSHPA/MCS Drilling Standard in February 2022 was as a direct result of her ambition to improve the standards within our industry.

Away from her work she enjoys family life and travel; particularly with her husband Geoff, 3 children and 5 grandchildren.
