Do Not Build Your Own Catering Trailer - Mechanical Extraction!


I'm just in the process of setting up a mobile catering trailer. I've looked at various sites and papers but can't seem to get a straight answer. Does anyone know if you by law have to install mechanical extraction ventilation above a chip fryer that is 90,000 btus.

The appliance has a flue spigot to the rear which could be inducted to outside quite easily but not sure if it has to be mechanically extracted? Any light on this matter would be much appreciated.

Catering hatch
by: Anonymous

I’m in the middle of converting a catering van, a luton style Fiat Ducato. All good ‘till now, when I have to build the hatch. I have a honeycomb panel for the hatch, but I don’t know if it’s strong enough to hold on to the hinge, especially because the capping frame will be only bonded to the panel. Has anyone built their own catering van? Any ideas regarding the hatch? Any suggestion will be appreciated. Thank you

And the answer to your fryer is yes all fryers now has to have a extraction canopy which must come out I think is 300mm pas the appliance that's on all new builds the overhead coverage must be greater than the actual appliances

Can you check that is correct, I was told that a converted vehicle can be taken to a VOSA testing station for an ‘Individual Vehicle Approval’ (IVA)

Concerns Regarding Building a Catering Trailer
by: Brian


I have some concerns regarding your enquiry when you state you are building a catering trailer. Note by law all new commercial catering trailers must be type approved and built by a VOSA registered builder, the electrical installation must be installed by NICEIC or similar registered Electrical installers and the gas installation must only be installed by a Gas Safe registered engineer qualified with LP1CMC, a gas engineer is not legally allowed to commission and claim as their own gas installations made by unqualified persons.

The fact that you are not aware that the serve hatch is not permitted to be included in ventilation calculations, as it is not fixed and permanent ventilation reinforces the above.

I strongly urge you to not go any further with your project, to avoid making costly mistakes, without engaging properly qualified specialists.
