Comprehensive Site Investigation Services

We are a team of professional engineers, technicians and drillers that together provide our clients with the ‘complete’ site investigation service.  We are commercially focused and our objective is to provide information for design and manage risk in a cost effective and prompt way.  We understand where our services fit within overall project delivery, from individual house builds to major infrastructure schemes; the ground investigation plays a key role.

The South West Geotechnical team have been operational together since the late 1980's and have a proven track record. We are proud to be used by all sectors and recently completed projects ranged from public sector infrastructure, residential, commercial, renewables, investment institutions and individual developers.  These projects were completed in a wide range of environments, from greenfield and brownfield land, nearshore, coastal, quarries, earthworks and airports.  Examples of our work can be found in our case studies page.


Our traditional work base is within South West England, however for specialist areas, such as utility scale solar developments, we work nation-wide and abroad.  The SWG team have been operational together since the late 1980s and have a proven track record.


Our quality, comprehensive and cost effective service is delivered by a joint venture of Hall Geoscience Ltd and Stunt Drilling Services Ltd – together we form South West Geotechnical Ltd.  

John Hall, Neil Forrow, Jim Stunt are the company Directors,

supported by team managers Ben Ogden (engineering) and Nick Worthington-Williams (laboratory). Nick also manages quality assurance for the laboratory and overall business.
