If you’ve recently converted your catering van, trailer, commercial restaurant, or burger van from natural gas to LPG (liquefied petroleum gas), you’ll need an LPG gas conversion certificate. Not only is it a legal requirement in many cases, but it’s also vital for safety, insurance, and peace of mind.
But the big question is: Where can I get my LPG gas conversion certificate in the UK? Here’s what you need to know.

Why You Need an LPG Gas Certificate

Whether you’re running a mobile food business or using gas appliances in a converted vehicle, having a proper LPG gas certificate proves your equipment is safe and fitted to UK standards.

Trading without one can lead to serious issues – from void insurance policies to legal penalties, or worse, accidents caused by poor installations. It’s not worth the risk.

Don’t risk trading without a valid certificate.

Who Can Issue an LPG Gas Conversion Certificate?

Only a qualified Gas Safe registered engineer with the relevant LPG qualification can issue an LPG gas certificate in the UK.

Important: Not every Gas Safe engineer is qualified to work with LPG, and even fewer are certified to inspect and approve gas systems in mobile catering units. Make sure to check that they are registered for:

  • LPG (not just natural gas)
  • Commercial catering or mobile catering units (depending on your setup)

Where to Find an LPG Gas Engineer

You can use the official Gas Safe Register website to search for a local engineer. Use the advanced search to filter by LPG and mobile catering qualifications.
You can also look for engineers who specialise in gas safety for food trucks, burger vans, trailers, and similar setups. Some catering suppliers and LPG gas suppliers have contacts or in-house engineers they can recommend.

What to Expect During the Inspection

The engineer will inspect your gas installation, test for leaks, check pressure levels, and make sure everything is fitted correctly and safely. If everything is in order, they’ll issue the certificate, often called a Gas Safety Certificate for LPG, CP44, or Commercial Mobile Catering Certificate.

If they find faults, you’ll need to get them fixed before a certificate can be issued.

Prices can vary depending on your location and the complexity of your setup, but you can expect to pay somewhere between £80 and £200 for an inspection and certificate.

If repairs or alterations are needed, this will cost extra.

Do I Need to Renew It?

Yes. It’s recommended – and often required – to have your gas appliances inspected annually. Most insurance companies and local councils will ask for an up-to-date certificate if you’re trading.

The Bottom Line

Getting your LPG gas conversion certificate isn’t just a tick-box exercise – it’s a must for anyone converting from natural gas to LPG in a food truck, trailer restaurant, or catering van. Make sure you use a Gas Safe registered engineer with the right qualifications for LPG and mobile catering.
