CompEx is the international scheme for competency validation and certification of personnel who work in explosive atmospheres. Through a network of independent training and assessment centres, the CompEx Scheme supports practitioners in a range of industrial sectors including oil and gas, chemicals, pharmaceuticals, food manufacturing and utilities.

The CompEx Scheme was developed in 1993 to provide the UK oil and gas sector with credible assurance of transferable skills and competency for electrical, control and instrumentation technicians operating in hazardous areas. Since that time CompEx has continued to incorporate a range of competency qualifications to embrace a diverse range of roles across differing industrial sectors.

CompEx qualifications continue to be reviewed, such as the Recognised Practitioner Programme (Ex01-04RPP) and the Water Utilities (Ex09-10) course, with a new Small Bore Tubing Inspection qualification being launched in 2024. CompEx is complementing existing qualifications with new digital learning including Behavioural Safety in Hazardous Areas and an Introduction to Hydrogen course.

CompEx and its network of independent Approved Training Providers will provide an ongoing programme of professional development to support practitioners throughout their careers.
