Don’t get turned away—get your trailer certified by a qualified engineer.
When you’re organising an event in the UK—whether it’s a food festival, outdoor market, county fair, or music gathering—trailers with gas appliances are often a core part of the setup. From catering vans to mobile bars and pop-up kitchens, they all rely on gas to serve customers efficiently. But did you know that every trailer using gas on site legally requires a trailers gas certificate?
Here’s everything you need to know about gas certification for trailers at events, and why it’s not just a legal requirement—it’s a crucial safety step.
What Is a Trailers Gas Safety Certificate?
A trailers gas safety certificate is an official document that confirms all gas appliances within a mobile unit—like a catering trailer or mobile kitchen—have been inspected, tested and deemed safe to use. It must be issued by a qualified Gas Safe registered engineer who specialises in LPG (liquefied petroleum gas) systems used in non-domestic mobile settings.
In simple terms, it’s proof that your gas set-up meets all safety standards required under UK regulations. Without one, your business could be refused entry to events or even face penalties.
Why Is It Important for Events?
Events often bring together large crowds in confined outdoor spaces, where health and safety is critical. A gas leak or faulty appliance in a mobile trailer can pose a serious risk—not just to your staff, but to the public.
Event organisers will almost always ask to see a valid trailers gas certificate before allowing a gas-fuelled trailer on site. It’s often part of the paperwork checked during setup, along with public liability insurance and food hygiene documents.
So if you’re planning to trade at any local event, festival or fair, make sure your certificate is up to date. It not only keeps you legally compliant, but also shows your professionalism and care for public safety.
What Does the Inspection Involve?
A certified Gas Safe engineer will carry out a full check of your trailer’s gas system. This includes:
- Inspecting the installation and pipework
- Checking for leaks using approved methods
- Testing ventilation and airflow
- Examining gas appliances (cookers, fryers, water heaters, etc.)
- Ensuring compliance with BS EN 1949 and UK LPG codes of practice
- Issuing a full report and certificate if all is in order
If any issues are found, the engineer will advise on what needs fixing before a certificate can be issued.
How Often Do You Need One?
For trailers used in public events or commercial settings, a gas safety certificate should be renewed annually. Some event organisers may even ask for a certificate that’s less than six months old, especially for large-scale events.
It’s also best practice to have your trailer checked before the start of your busiest trading season—even if your certificate hasn’t yet expired.
Who Can Issue a Trailers Gas Certificate?
Only engineers listed on the Gas Safe Register with the correct LPG qualifications are legally allowed to inspect and issue gas certificates for trailers. Always ask to see their Gas Safe ID card and make sure it covers commercial mobile catering.
Avoid cutting corners—using unqualified contractors not only risks safety, but can also invalidate your insurance and leave you open to fines.
How Much Does It Cost?
The cost of a trailers gas certificate can vary depending on your location and the complexity of your setup, but most businesses in the UK can expect to pay between £155 and £350. Some engineers may offer group rates if several trailers need inspecting at once—ideal for event organisers or street food collectives.
