Miller Drilling Contractors

Miller Drilling Contractors provides specialist commercial geothermal borehole drilling and ground loop installation for ground source heat pump projects throughout the UK. We work alongside GSHP installers, principal contractors, M&E contractors, developers, consultants and energy specialists to deliver the drilling element of commercial ground source heat pump installations.


Commercial borehole arrays

Large ground source heat pump systems can require substantial numbers of vertical boreholes. As the size of a borehole field increases, drilling productivity, site logistics, water management, drilling fluids, loop installation and coordination with the wider construction programme become increasingly important.

Our commercial drilling operation is structured around these requirements.
