Guide - Mobile Catering - UK-Wide
A trailer or van packs canopy, filters, grease trap, flue and fan into a few square metres, with grease, flame and LPG all close together. Here is why a compact system still needs cleaning - and how it ties to gas safety.
The short answer
A trailer, van or stall does not have ductwork running through a building - it has a compact canopy, a short flue, filters, a grease trap and a fan, all packed into a few square metres. That compactness is not a let-off. Grease, naked flame and an LPG supply sit close together in a confined space, so a mobile system needs cleaning regularly and treating as a real fire risk:
The fixed-kitchen standard is built around long ducts, but the principle is the same: control the grease, keep the system pulling, and prove it is maintained.
What there is to clean
Mobile catering leans heavily on frying and griddling - burgers, loaded fries, chicken, fish - which is high-grease cooking in a very small box. Heat, grease and airflow become a problem quickly in a confined unit, and the parts that have to be kept clean are the same ones a big kitchen has, just smaller:
Because the run is short and tight, grease concentrates rather than spreading out - so the system shows the load quickly, and an end-of-trading wipe-down plus a regular thorough clean is the realistic rhythm.
Cleaning meets gas safety
In a mobile unit the extraction is bound up with the gas safety regime in a way a fixed kitchen does not always feel. A few points that sit alongside the cleaning:
Why it matters
The thing that makes a mobile unit different is proximity. In a building, a grease fire in the duct has somewhere to travel; in a trailer, everything - the fryer, the greased canopy, the gas, and the people working - is within arm's reach of each other. A fire here is immediate and personal, which is precisely why keeping the compact extract system clean and the gas regime in order is not box-ticking but basic self-protection.
The workable approach is a regular professional clean of the canopy, filters, grease trap, flue and fan, an operator routine of daily filter and surface cleaning, and a gas set-up that is certificated and interlocked to a working extract. Small system, same discipline - kept clean, kept moving air, kept safe.
Questions
Yes. Mobile catering leans on frying and griddling, which is high-grease cooking in a confined space where heat, grease and flame sit close to the LPG supply. The compact canopy, filters, grease trap, flue and fan all load with grease and need regular cleaning.
Filters and surfaces are typically an operator job at the end of each trading period, with a thorough professional clean of the whole compact system on a regular interval. Because the run is short and tight, grease concentrates and shows quickly, so the rhythm is usually more frequent than people expect.
Closely. Modern units are interlocked so the gas only runs when the ventilation is running, which relies on the extract being clean and moving air. A mobile unit also needs an annual gas safety check by a Gas Safe registered catering engineer - a clean, working extract system is part of a safe set-up.
Proximity. In a building a duct fire has somewhere to travel; in a trailer the fryer, the greased canopy, the LPG and the people are all within arm's reach. A grease fire is immediate, which is exactly why keeping the compact system clean matters.
Yes. We work around your trading pattern, cleaning the compact system between events or pitches so it keeps pulling air and stays inside safe limits, with documentation for your records.
