In many cases, we provide contract drilling services for groundwater, geothermal, and geotechnical boreholes. In others, we take full ownership of the project, managing every stage — from geophysical surveys, calculations, and design, through drilling, system implementation, post-installation testing, and ongoing maintenance.
Our team delivers complete end-to-end project management, from initial scoping to drilling and final delivery of a full Ground Source Heat Pump system or Groundwater Abstraction System. For larger commercial or residential developments, we also partner with trusted companies who can provide funding for heat networks, with costs recovered through usage billing.
Getting it right from the very beginning is important to us. That’s why we always conduct thorough research into each site’s geology before making any recommendations. We’ll request a detailed breakdown of the building’s heating, cooling, and hot water requirements, and, if needed, arrange a full independent geological survey. Once the data is confirmed, we provide a transparent, fixed-price quotation. Our tailored packages often include partnerships with specialist consultants and expert recommendations on heat pumps.
Before any work begins, we visit the site to initiate project management and provide clients with a detailed information pack specific to their property. As part of our service, we also supply full drilling logs and register all new boreholes with the British Geological Survey.
Once we receive your phone call or email enquiry, we assess your site size, accessibility, and Ground Source Heat Pump (GSHP) output requirements. Within a few days, you’ll receive a written preliminary estimate
For larger projects, we may recommend a British Geological Survey (BGS) report (approx. 3 weeks, costing a few hundred pounds) and a site visit. Based on this, your initial quote will be confirmed or refined. At this stage, we can also provide a Method Statement and full Risk Assessment documentation. If you wish to proceed, a security deposit will secure your project schedule with start and completion dates.
Before drilling begins, we require a map of all underground utilities (water, gas, sewerage, electricity, etc.). We then mobilise the drill rig, mud cleaning unit, and supporting equipment. For larger sites, multiple rigs may be used to keep work efficient and avoid delays.
Depending on site conditions, each borehole typically takes 1–2 days to complete. Once drilled, loops are mechanically inserted using a hydraulic reel and then pressure-tested. A high-quality grout mix is pumped into the borehole from the bottom up to ensure durability and performance.
After drilling, we connect the boreholes through manifold and header pipes back to the GSHP location. Further GSHP works can be completed by AWGeothermal or a trusted third party. On completion, we leave the site tidy and with minimal disruption.
