LPG Testing & Commissioning
A gas network does not enter service before its tightness and the integrity of its protection systems are proven. We test the complete network and then each pressure stage, test the detector together with the shut-off valve as one interlocked system, commission the appliances, and hand over with a report stating what was tested and the result.
Test programme
- Pressure and tightness testing before covering up
- Joint and tie-in inspection
- Regulator setting and verification of each stage pressure
- Valve and isolation point functional checks
- Gas detector testing and control panel response
- Solenoid valve and emergency shut-off testing
- Appliance trial operation and performance observation
- Documented test and handover report
Operator familiarisation
We brief the site team on isolation points, the emergency shut-off procedure, what the alarm panel indications mean and what to do on a suspected leak — that knowledge is part of safety, not an optional extra.
Deliverables
- Pressure and tightness test report
- Safety system test report
- Regulator setting record
- Commissioning and handover record
- Site team familiarisation
Where this service applies
- New project handover
- After extension or modification
- Before resuming service after a shutdown
- Verification of an existing network
- Meeting authority requirements

Frequently asked questions
Is a pressure test alone enough?
No. A pressure test proves tightness only; detection and emergency shut-off systems need a separate functional test to prove they respond.
Do you test a network installed by others?
Yes, after a survey that establishes readiness and documents observations before testing begins.
Have a project or an existing facility that needs an engineering review?
Our engineering team can review your requirement and propose a solution suited to the application, the site and the applicable requirements.
