Ground Source Heat Pumps and Sewage Treatment Systems


Open-Loop Ground Source heating can reduce conventional heating bills by over 50%. In a time where energy prices are soaring this is a saving worth investigating.

H.D. Geothermal is part of H.D. Services Ltd, a fully MCS accredited company. We aim to provide the highest quality Open-Loop Ground Source Heat Pump service available in South East England. Our customers can rely on our advice and flexibility to suit their individual requirements and we associate ourselves with suppliers who adopt a similar ethos. H.D. Services Ltd is committed to completing contracts on time and use only directly employed labour.

Our sister company, H.D. Drilling Ltd, carry out all drilling works associated with the installation of our Open-Loop Ground Source Heat Pump systems.  H.D. Drilling Ltd has been constructing water supply and soakaway boreholes in the South East of England since 1984. They have been members of the Well Drillers Association (WDA) since 1988 and have a vast knowledge of the hydro-geology. This means that they can generally confirm the feasibility of a proposed installation upon the receipt of a site postcode.


Since 1984 H.D. Services has been developing sewage treatment systems culminating with the introduction of their HD-SM in 1994. Over the years we have installed hundreds of HD-SM sewage treatment systems throughout southeast England serving thousands of people.

Our unique modus operandi covers design, supply, installation, commissioning, and servicing. We do not employ agents to sell or install our systems and can take full responsibility for ensuring the discharge complies with the consent issued by the Environment Agency.

Both H.D. Services Ltd and H.D. Drilling Ltd are BS EN ISO 9001 and BS EN ISO 14001 registered companies.

An initial telephone call to our offices will result in the receipt of a budget proposal with prices for consideration at your leisure. Our engineers can visit the site, free of charge and without obligation, to assess and measure the site.
