Mobile Caterers – busy times

Savvy event organisers have realised that the mobile catering units (fitted with gas-fired catering equipment) they allow on-site need to have been properly tested and certified. Many organisers and site operators now insist that the caterers provide evidence that a gas safety check has been carried out by a competent and qualified Gas Safe registered engineer.

Mobile catering units come in all shapes and sizes and contain a variety of equipment depending on the the food being prepared. The common elements found (in many of the more professional units at least) are:

  • Gas cylinders
  • Regulators and changeover valves
  • Emergency control valves
  • Pipework
  • Appliance connections
  • Appliances
  • Ventilation

For many owners / operators of a mobile catering unit the next 6 months are likely to be the busiest time of year. Don’t get caught out and miss part of the busy season because you haven’t had the necessary testing and certification done on time – remember that the law says catering trailers should be inspected every 6 months preferably, but at least every 12 months.
