About Us

RS RigEstablished in 1990 we are a small specialist drilling company concentrating on environmental projects. Its founder Chris Jeffries worked previously as a consultant for a major international environmental and geotechnical consultancy. While supervising a contamination investigation project in The Netherlands he experienced an environmental drilling service far superior to what was available in the UK at the time and soon after established ESL, aiming to offer a drilling service similar to the Dutch model. ESL started with window sampling but was then the first company to offer hollow stem auger drilling for environmental investigatons. Since then our reputation has become established with many consultancies and other organizations. We have drilling experience throughout the UK, from the Orkney Isles to the Channel Islands & in much of Europe and parts of Africa.

We currently offer 3 Nordmeyer rotary rigs, 2 sonic rigs and various window sampling systems, we also carry out decommissioning and some bioremediation work. We concentrate on various shallow drilling and probing techniques and most of our drilling work is to depths within 20m, however we do have greater capability. We also subcontract other drilling services where necessary.


The bulk of our environmental investigation work is at petroleum / chemical facilities, light / heavy industry, demolition and landfill sites, anywhere where contamination may be suspected or encountered. Here follows a selective list of projects worked on since 1990.

Range of Augers


We are always glad to hear from suitable people who want to work with us regardless of whether a vacancy is available.

Trainee Driller

ESL often requires ambitious, keen and enthusiastic personnel with a positive attitude to work on our drill rigs. This work can be dirty and wet and carries on no matter what the weather conditions. On the other hand we work in some fantastic and unusual places for interesting clients. Work is throughout the UK and may require occasional weekend work.

Work involves a high degree of practical skills working with mechanical equipment and driving company vehicles, often with trailers (licence with B+E / C1+E beneficial). Drilling training would be in the safe operation of a variety of equipment to include hand held to medium sized rotary drill rigs. Training would be given but experience of site work would be advantageous. An understanding of geology would be helpful.

Any person should like the outdoor life, be prepared to travel away from home and to train as a lead driller. Good hand writing and communicative skills are essential as is a clean driving license.

To be considered for any upcoming vacancies please send your CV accompanied by a hand written letter.
