Guide - TR19 Grease - UK-Wide
A venue is dozens of kitchens that sit idle then load hard on a single event day. Here is why intermittent use still fills the ducts, and how a whole estate of hoods is cleaned between fixtures.
The short answer
A stadium or event venue is not one kitchen - it is dozens of independent ones: concourse kiosks, hospitality suites, club lounges and back-of-house kitchens, each with its own hood, ductwork and fan. They sit quiet between fixtures, then load hard on a single big day, so the cleaning is planned around the calendar of events:
The grease is real even though the kitchens are dark most of the time - because when they cook, they cook flat out for thousands of people.
The matchday spike
The pattern at a venue is the opposite of a steady restaurant. A concourse kiosk might do nothing for a fortnight, then fry chips, burgers and chicken for a packed stand across a few intense hours. Multiply that by a full programme of fixtures and concerts and the system quietly accumulates a season's worth of grease across a relatively small number of very heavy days. Judging the interval by the calendar - "it is only used now and then" - badly underestimates the load, because the load is concentrated, not light.
The dormant spells make it worse, not better. Between events the grease already in the ducts sits and hardens rather than clearing, so a system left from one season to the next builds a tougher deposit than the cooking hours alone suggest. The right measure, as everywhere, is the grease itself - and at a venue that means surveying the systems that actually do the heavy frying, not assuming intermittent equals clean.
Cleaning at venue scale
The saving grace of a venue is that it has natural windows - the days between fixtures and the close season - which are exactly when facilities teams run their safety inspections and compliance work. Extraction cleaning fits the same slot, and at scale it takes:
Why it matters
The reason venues take this seriously is scale on both sides. A site with dozens of frying kiosks carries a great deal of grease across its ducts, and on an event day it has tens of thousands of people in the building. A grease fire in a concourse extract system, with crowds packed into the stands above and around it, is precisely the scenario the whole compliance regime exists to prevent. The intermittent use is not a reason to relax - the concentration of risk on the days that matter is the reason to be thorough.
The workable approach is to survey the kitchens that do the real frying, set each its own interval from the measured load, clean the estate between events with scaled overnight teams, and hold one coordinated set of certificates. The venue stays event-ready, and the grease that builds across the big days never gets the chance to become the fuel for one.
Questions
Yes, and often more than expected. On a big day a kiosk fries flat out for thousands of people, so across a season it deposits a great deal of grease in a small number of very heavy days. Intermittent use concentrates the load rather than reducing it.
Between events and in the close season - the same windows facilities teams use for safety inspections and compliance work. Scaled teams can clean across multiple concourses overnight so the estate is ready for the next fixture without disruption.
No. The systems that do the heavy frying load far faster than lighter ones, so each should be surveyed and given its own interval from the measured grease load rather than a single blanket date across the venue.
It builds on the busy days and then hardens during the idle spells, so a system left from one season to the next carries a tougher deposit than the cooking hours suggest. Cleaning between events clears it before it sets.
Yes. We treat the venue as a portfolio - surveying each system, setting its interval, cleaning across concourses overnight, and issuing one coordinated set of certificates and photographs that reads as a single compliance picture for your fire safety officer and insurer.
