LPG Gas Safety Certificate
Comprehensive LPG gas safety certificates for commercial and leisure installations — from cylinder storage and regulators to pipework and appliances.
Officially RegisteredWhat is a LPG Certificate?
The LPG Gas Safety Certificate covers the inspection and certification of Liquefied Petroleum Gas installations in commercial and leisure settings. LPG (propane or butane) is used where mains natural gas is unavailable — including rural businesses, temporary sites, outdoor catering, construction compounds, and leisure accommodation.
LPG installations differ significantly from natural gas systems. The gas is heavier than air, so leak detection, ventilation, and cylinder storage requirements are more stringent.
Our Gas Safe registered engineers hold the specific LPG qualifications (including CONGLP1 and ACS LP categories) needed to inspect, test, and certify every type of LPG installation.
The certificate covers the entire LPG system — from the gas cylinders or bulk tank, through regulators, changeover valves, and pipework, to every connected appliance.
We provide same-day LPG gas safety certificates across London and the surrounding areas. Certificates are completed and handed to you on the day of inspection.
Gas Engineer Certificate
An LPG gas engineer certificate is issued only by a Gas Safe registered engineer holding the correct LPG qualifications. It confirms your LPG installation — cylinders or bulk tank, regulators, pipework and appliances — has been inspected, tested and certified safe for continued use in domestic and commercial properties.
Why Do You Need a LPG Certificate?
Any business or landlord operating LPG-fuelled appliances must hold a valid gas safety certificate. Insurance companies, local authorities, and the HSE all require proof that LPG systems have been inspected by a Gas Safe registered engineer with the correct LPG qualifications. Without a valid certificate, your insurance is likely void and you risk prosecution.
📋 Legal Requirement
Under the Gas Safety (Installation and Use) Regulations 1998 and the Liquefied Petroleum Gas Association (LPGA) Codes of Practice, all LPG installations must be inspected annually by a Gas Safe registered engineer holding the appropriate LPG category on their registration.
🔄 How Often?
Every 12 months. Bulk tank installations may also require periodic inspections under the Pressure Systems Safety Regulations 2000.
Gas Appliances Covered & Required Qualifications
Each appliance type requires the engineer to hold a specific ACS (Accredited Certification Scheme) qualification on their Gas Safe registration. Our engineers hold all of the qualifications listed below.

| Automatic changeover valve (twin cylinder) | CoNGLP1 + ICPN1 (Commercial Pipework) |
| First-stage regulator (high to intermediate pressure) | CoNGLP1 + ICPN1 (Commercial Pipework) |
| Second-stage regulator (to appliance pressure) | CoNGLP1 + ICPN1 (Commercial Pipework) |

Who Needs This Certificate?
⚠️ What Happens Without a Valid LPG?
Operating without a valid gas safety certificate puts your business, staff, and customers at serious risk:
- ✗LPG is heavier than air — leaks pool at ground level creating explosion risk
- ✗Insurance policies voided without a valid certificate
- ✗HSE prosecution and unlimited fines
- ✗Premises closure by local authority
- ✗Personal criminal liability for injuries or fatalities
LPG Inspection Checklist
Every item below is verified by our Gas Safe registered engineer during the inspection:
Inspect LPG cylinder storage location and ventilation
Check cylinder condition, valve, and securing method
Test changeover valve operation (if twin-cylinder setup)
Inspect first-stage and second-stage regulators
Test regulator outlet pressure with a manometer
Carry out gas tightness test on all pipework
Check all pipework supports, clips, and protection sleeves
Inspect flexible hose connections for damage and expiry dates
Test flame failure devices on every appliance
Perform combustion analysis (CO, CO₂, O₂) on each appliance
Check ventilation openings are adequate and unobstructed
Test emergency shut-off valve operation
Verify cylinder storage complies with LPGA Code of Practice 7
Check for correct signage ('LPG — Highly Flammable')
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
Warning Notices Explained
When a fault is identified, the engineer records it formally. Here is what each notice type means for you and your premises:
At Risk Notice
Issued when an appliance does not fully conform to current standards yet is not life-threatening. The responsible person — landlord, manager, or business owner — is informed and should arrange repairs without delay.
Practical impact: The appliance may remain in use at your own risk while repairs are scheduled. However, if you decline to act, the engineer can escalate the classification to Immediately Dangerous.
Immediately Dangerous Notice
Issued when there is a direct and immediate risk to life. The engineer disconnects and caps the gas supply to the appliance without exception.
Practical impact: The appliance is labelled "DO NOT USE" and cannot be reconnected until a Gas Safe registered engineer completes repairs, confirms safe operation, and issues a new safety record.
