Gas Purging Decommissioning
Gas Purging & Testing Services
Gas purging is a controlled process used when installing, modifying, or decommissioning commercial and industrial gas pipework. The procedure safely removes combustible gas from pipework systems, or introduces gas into pipework, without creating a hazardous atmosphere.
Where alterations are required to existing gas mains or pipework, a controlled purge ensures the system can be safely worked on before any modifications take place.
Once the purge procedure has been completed, the gas installation can be safely altered, extended, or removed, with the assurance that no combustible gas remains within the system.
Phoenix Heating (Luton) Ltd provides professional gas purging and gas testing services for commercial and industrial installations, carried out by competent Gas Safe registered engineers in accordance with recognised industry procedures.
Safety is our highest priority. All work is carefully planned and carried out using appropriate equipment and procedures to ensure that gas installations are made safe before work begins.

With extensive experience working in plant rooms, commercial kitchens, and large gas installations, our engineers understand the importance of safe isolation, correct purge calculations, and controlled testing procedures.
Whether you require gas pipework purging for new installations, alterations to existing systems, demolition projects, or full gas pipework testing and certification, our engineers provide a safe, professional, and efficient service.

What Is A Gas Purge?
When Gas Purging Is Required
Gas purging is required when gas pipework systems are being installed, modified, commissioned, or decommissioned. The procedure safely removes combustible gas from pipework, or replaces air with gas, to ensure the system can be worked on or brought into service without creating a hazardous atmosphere.
Gas purging is commonly required during:
- Installation of new commercial gas pipework or plant
- Alterations or extensions to existing gas mains or pipework
- Decommissioning gas installations prior to building demolition or refurbishment
- Commissioning new boilers, plant rooms, or commercial kitchens
- Strength and tightness testing of gas installations
Purging procedures are carried out in accordance with recognised industry standards to ensure the gas system can be safely modified, tested, or commissioned.
