Mobile Catering Vehicle Trailer Certificate (CP44)
Gas safety certificates for food trucks, market stalls, catering trailers, and any mobile or temporary LPG catering setup. Certified same-day.
Officially RegisteredWhat is a CP44 Certificate?
The CP44 certificate covers gas safety for mobile catering units that use LPG (Liquefied Petroleum Gas). This includes food trucks, catering trailers, market stalls, and any mobile unit that uses gas for cooking or heating.
The CP44 certificate is required for mobile catering vehicles, trailers, and market stalls that use LPG gas.
This certificate covers all gas appliances and LPG systems within mobile catering units.
Environmental health officers and local authorities require valid CP44 certificates before mobile catering units can trade at events, markets, and festivals.
The inspection covers the entire LPG system from the gas cylinder through regulators, pipework, and every appliance in the unit.
Why Do You Need a CP44 Certificate?
Event organisers, local councils, and Environmental Health Officers require a valid CP44 certificate before allowing mobile catering units to trade. Without one, you cannot legally operate at events, markets, or festivals.
📋 Legal Requirement
Under the Gas Safety (Installation and Use) Regulations 1998, all gas installations in mobile catering units must be inspected annually. The Workplace (Health, Safety and Welfare) Regulations 1992 also apply.
🔄 How Often?
Every 12 months. Some event organisers and councils require certificates less than 6 months old.

CP44 Inspection Checklist
Every item below is verified by our Gas Safe registered engineer during the inspection:

Check LPG cylinder storage and security
Inspect gas regulator and changeover system
Test all gas connections and pipework for tightness
Check gas hoses for damage, kinks, or expiry dates
Test flame failure devices on all burners
Inspect ventilation openings (fixed and adjustable)
Check drop-out holes are clear and correct size
Test emergency gas shut-off valve
Perform combustion analysis on each appliance
Check gas appliance stability and securing
Inspect electrical connections near gas equipment
Verify fire extinguisher and fire blanket are present
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 LPG Cylinder Onwards

From the LPG Cylinder Valve Onwards
Our engineers inspect the entire LPG system from the cylinder valve through the changeover regulator, all pipework, and every connected appliance. The gas cylinders themselves are the responsibility of the LPG supplier.
Included in the inspection:
- ✓ LPG cylinder connections and changeover valve
- ✓ High-pressure hoses and first-stage regulator
- ✓ Second-stage regulator and low-pressure pipework
- ✓ All connected catering appliances (fryers, griddles, ranges, etc.)
- ✓ Flame failure devices and safety controls
- ✓ Ventilation and flue arrangements within the unit
- ✓ Drop-tight testing of isolation valves
Not included:
- ✗ The LPG cylinders themselves (supplier's responsibility)
- ✗ External cylinder storage cage or compound
- ✗ Vehicle roadworthiness or MOT
Smell gas from a cylinder? Turn off the cylinder valve, ventilate the area, and call the National Gas Emergency Service on 0800 111 999.
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.
