At SDA Site Investigation LTD, we provide professional geothermal drilling services to support ground source heating systems. As more homeowners and businesses look for sustainable alternatives to traditional energy, geothermal technology has become an increasingly popular solution.
Our drilling expertise ensures your system is installed on strong, safe foundations, delivering a long-lasting and environmentally friendly source of renewable energy.







Geothermal drilling involves creating deep boreholes that allow ground source heat pumps to extract natural heat stored within the earth. This renewable energy can then be used for heating, cooling, and hot water, providing a cleaner and more efficient alternative to gas or electricity.
By drilling boreholes to the correct depth and specification, we enable your system to operate at maximum efficiency while ensuring full compliance with industry standards.
