Our Gas Safety Inspection Process
Thorough Visual Assessment
Our engineer examines every gas appliance, pipe run, and fitting for wear, corrosion, or non-compliant installation before any testing begins.
Pipework Integrity Testing
We pressurise the gas pipework downstream of the meter and monitor for any drop, confirming no leaks exist within your installation.
Flue & Ventilation Checks
We verify that all flues draw correctly and combustion gases are safely evacuated, protecting your premises from carbon monoxide build-up.
Combustion Performance Analysis
Using calibrated flue-gas analysers, we measure CO, CO₂, and O₂ concentrations to confirm each appliance burns efficiently and within safe limits.
On-the-Spot Certification
Once every check passes, your Gas Safe registered engineer issues the relevant certificate immediately — no waiting, no follow-up visits.
Scope of the Inspection — From the Meter Onwards
Downstream of the Gas Meter Only
By regulation, our engineers inspect and test the gas installation from the outlet of the gas meter onwards. Everything upstream — the service pipe and the meter itself — falls under the gas transporter's responsibility.
Included in the inspection:
- ✓ All internal gas pipework from the meter to each appliance
- ✓ Every connected gas appliance (boilers, cookers, heaters, etc.)
- ✓ Isolation valves and emergency controls
- ✓ Flue systems, ventilation openings, and extraction
- ✓ Operating pressure at each appliance
Not included:
- ✗ The incoming supply pipe before the meter (gas transporter's asset)
- ✗ The gas meter itself (owned by your gas supplier)
- ✗ Any leak or fault on the supply side of the meter
Suspect a gas leak before the meter? Call the National Gas Emergency Service on 0800 111 999 immediately — it is free and available 24/7.
Understanding Inspection Outcomes
Every appliance inspected receives one of three classifications. Knowing what each means helps you respond quickly and keep your business running safely.
Satisfactory
The appliance meets all current standards and is safe to operate. Simply schedule your next annual check and continue trading with confidence.
At Risk (AR)
The appliance falls short of current standards but poses no immediate threat to life. Continued use is at the responsible person's discretion while remedial work is arranged promptly.
- • Ventilation below recommended levels
- • Minor flue joint deterioration
- • Overdue servicing or worn seals
- • Damaged flame supervision device
Immediately Dangerous (ID)
The appliance poses an immediate risk to life. The engineer must disconnect and isolate it on the spot. Reconnection is only permitted after a qualified repair and a fresh safety inspection.
- • Active gas leak detected
- • Blocked or severed flue
- • Dangerously high CO readings
- • Flame failure device bypassed
- • Critical ventilation deficiency
We also service the equipment we can't certify — fridges, freezers and AC. One call, one engineer team.
