Extraction cleaning - takeaways
A takeaway is about the greasiest kind of kitchen there is - and its extract system pays for it. Heavy frying loads the ductwork with grease fast, which is exactly why takeaway extraction needs cleaning more often than most.
The short answer
Takeaways do a lot of frying, the greasiest cooking there is, so their extract systems load with grease far faster than most kitchens - which means the fire risk builds faster and the cleaning frequency has to be higher to control it. A takeaway extract system on a light-kitchen cleaning interval will be dangerously greasy long before its next clean. High grease demands high frequency; that is the core of takeaway extraction cleaning.
Why takeaways load the extract fast
Takeaways are dominated by frying and grilling - the cooking methods that throw off the most grease - often at high volume through long hours. All that grease goes somewhere, and much of it is drawn straight into the extract system, coating the canopy, filters, ductwork and fan. Compared with a kitchen doing lighter, less greasy cooking, a takeaway loads its extraction with grease at a much higher rate.
So a takeaway extract system accumulates grease fast and heavily. This is not a failing - it is the nature of frying hard for a living - but it does mean the hidden grease build-up that any extract system has to manage arrives far quicker in a takeaway. The system reaches a dangerous grease level in a fraction of the time a lighter kitchen would take.
Why that raises the risk
The fire risk from an extract system rises with the grease in it, and a takeaway's system reaches a high grease level quickly. That means the fire risk in a takeaway extract - grease as fuel, in concealed ductwork and on a hot fan, where a fire can start and travel - builds towards the dangerous threshold sooner than in almost any other kind of kitchen. The heavy frying that defines a takeaway is also what makes its extraction a high fire risk.
This is why takeaway extraction is treated as high-risk. It is not that the system is worse, but that it greases up faster, so it spends more of its time closer to the level at which it becomes dangerous - unless it is cleaned often enough to hold it back. The high grease load is a high fire risk waiting on the cleaning interval.
Why frequency is the answer
Because grease is what drives the risk and takeaways build grease fast, the control is frequency - cleaning the extract system often enough to keep the grease below the dangerous level. A takeaway on the same cleaning interval as a light-use kitchen will be well over a safe grease level long before its next clean, so the interval has to be shorter, matched to how fast the system actually greases up.
This is exactly how the risk-based cleaning frequency works: the heavier and greasier the cooking, the shorter the interval. A heavy-frying takeaway sits at the frequent end - potentially cleaning its extract every few months rather than annually - because that is what its grease load requires to stay safe. High grease demands high frequency, and the frequency is set by measuring how fast the takeaway's system builds up.
The whole system, often
Two things follow for a takeaway. First, the cleaning has to reach the whole system, not just the canopy - the concealed ductwork and the fan are where the fast-building grease creates the fire risk, so a canopy wipe leaves the danger in place however often it is done. Second, it has to happen often, on an interval matched to the takeaway's heavy grease load rather than a generic annual assumption.
Together these define takeaway extraction cleaning: the whole system, cleaned frequently, verified to standard. A takeaway that cleans only the canopy, or cleans the full system but only once a year, is under-controlling a fast-building fire risk. Getting both right - full-system cleaning at a high, grease-matched frequency - is what keeps a takeaway's extraction safe despite all the frying.
The takeaway
The principle is simple: match the extract cleaning to how hard the kitchen fries. A takeaway fries hard, loads its extraction fast, and builds fire risk quickly - so it needs the whole extract system cleaned frequently, at an interval set by measuring its real grease build-up, and verified each time. That is more cleaning than a lighter kitchen needs, and it is exactly proportionate to the higher risk the frying creates.
For a takeaway operator, this is not an imposition but the sensible control for a real, fast-building hazard. The heavy frying that makes the business also makes the extraction a high fire risk, and frequent, full-system cleaning is what keeps that risk in check. High grease, high frequency - the cleaning simply keeps pace with the frying that generates it.
Questions
Because they fry hard - the greasiest cooking - so their extract systems load with grease far faster than most kitchens. The fire risk builds faster, so the cleaning frequency has to be higher to control it.
The fire risk rises with the grease in the system, and a takeaway's system reaches a high grease level quickly - so its extraction spends more time closer to the dangerous threshold unless cleaned often enough to hold the grease back.
On a short, risk-based interval matched to how fast its system greases up - potentially every few months rather than annually. The exact frequency is set by measuring the real grease build-up, which is heavy in a takeaway.
No. The fast-building grease creates its fire risk in the concealed ductwork and on the fan, so a canopy clean leaves the danger in place however often it is done. The whole system has to be cleaned.
Its extract system will be well over a safe grease level long before the next clean, carrying a high fire risk in its concealed ductwork and fan - and likely lapsing its compliance and insurance cover too.
The whole system cleaned - canopy, filters, ductwork, plenum and fan - at a high frequency matched to the takeaway's heavy grease load, and verified to standard each time.
We clean takeaway extract systems whole and often, on a frequency set by how fast your system loads up - keeping a fast-building fire risk in check.
