Commercial Gas – Testing & Purging

Commercial Gas Testing, Purging & CP16 Certification

Our Services

What does it involve?

Atlas Gas provides commercial gas testing, purging and CP16 certification services for businesses, contractors and property owners. Whether you’re introducing gas into a new installation, reinstating supply following works, or carrying out decommissioning purges as part of building alterations, removals or demolition projects, our experienced engineers will manage the process safely, professionally and in full compliance with current standards.

Testing and purging form a critical part of ensuring a gas installation is safe before it is brought into use or taken permanently out of service. Where new pipework has been installed or existing pipework has been modified, strength testing is carried out first to confirm the integrity of the installation, followed by tightness testing prior to introducing gas.

Pipework Testing and Purging

Once testing has been successfully completed, controlled purging operations are undertaken to safely introduce or remove gas from the pipework as required. Purging is carried out in a safe manner, away from sources of ignition and in suitable locations, using approved methods to ensure gas is safely dispersed.

All testing and purging works are completed in accordance with IGE/UP/1 (IGUP1) guidance and current industry best practice, with safety as the priority at every stage. As part of this process, Atlas Gas issues CP16 Gas Safety Certificates where required, providing confirmation that the installation has been tested, purged and commissioned in line with current regulations.
