Marriott Drilling Group is the UK’s only remaining truly independent land Drilling Specialist, trusted for over 75 years to deliver safe, efficient and technically robust drilling solutions across geothermal, oil & gas, water-well, mining and energy-transition projects.

Our reputation is built on operational excellence, low non-productive time performance, and the quality of our people. We retain long-standing, highly competent crews and operate under ISO-accredited management systems, supported by in-house engineering, manufacturing, and project management capability.

We work across the UK, Europe, Africa, Asia and Central & South America, with an increasing focus on geothermal and clean-energy applications, partnering with governments, utilities and developers to accelerate sustainable energy supply and responsible natural-resource development.

As a family-run organisation, Marriott Drilling remains committed to integrity, safety and local employment, delivering value for our clients and positively contributing to the communities in which we operate.
