CompEx Certified Installations – Safe, Compliant Work in Hazardous Environments

At Reliance Systems Ltd, our engineers are CompEx certified — the UK’s recognised standard for electrical work in explosive or hazardous atmospheres. This qualification is vital when installing fire detection, security, or CCTV systems in environments with a risk of flammable gases, vapours, or combustible dust.

For clients in industries such as oil & gas, chemical processing, food and drink manufacturing, and distilling, this certification ensures that all system installations are carried out safely, legally, and in full compliance with ATEX and IECEx directives.

- Adherence to EX-rated equipment specifications and correct cable glanding and routing
- Engineers trained to understand ignition sources, zoning, and protection concepts
✔ System Commissioning
- Full testing and verification of system performance under hazardous area requirements
