Safety & Precision for Explosive Environments

One of the few CompEx 1–4 certified contractors in the South West. We deliver ATEX-compliant installation and inspection for high-risk sites, including fuel depots and MoD facilities.

CompEx Certified Hazardous Area Electricians

Working in hazardous areas requires specialist training, strict compliance and absolute precision. Environments containing flammable gases, vapours, dust or volatile substances demand electrical systems that are correctly designed, installed and maintained to prevent ignition risks.

Lawson Electrical is proud to be one of a limited number of CompEx certified electrical contractors serving Cornwall and the wider South West. Our qualified engineers are authorised to work under ATEX Directives, ensuring all electrical installations and inspections in explosive atmospheres meet the highest safety standards. When safety, compliance and operational continuity are critical, we deliver expert hazardous area solutions you can rely on.

What Is CompEx & ATEX Certification?

CompEx certification demonstrates proven competency in working within explosive atmospheres. ATEX, short for “ATmosphere EXplosible”, governs electrical and mechanical equipment used in potentially explosive environments.

These regulations apply to facilities such as fuel depots, airports, manufacturing plants, processing sites and Ministry of Defence locations. Any environment where dangerous substances are present — including solvents, paints, varnishes and flammable gases — falls under strict compliance requirements.

Lawson Electrical holds CompEx 1–4 qualifications, enabling our engineers to safely inspect, test, install and maintain electrical systems in hazardous zones. We ensure all work complies with ATEX Directives and DSEAR regulations, protecting both your workforce and your facility.
