Kitchen extraction - the boundary
The canopy sits at the boundary between two different jobs. A kitchen deep clean addresses its visible surfaces; the extract system it feeds into is a separate, specialist clean to a fire-safety standard. Knowing where one ends and the other begins is knowing what your deep clean actually covers - and what it does not.
The short answer
The canopy marks the boundary between a general kitchen deep clean and specialist extract cleaning. A deep clean addresses the canopy's visible, accessible surfaces and often its filters as part of cleaning the kitchen. But the extract system the canopy feeds - the ductwork and fan behind it - is a separate, specialist job, cleaned to the TR19 Grease fire-safety standard with its own verification. Understanding that the canopy sits at this boundary tells you what a deep clean covers on it, and what still needs the separate extract clean.
The canopy sits between two jobs
The canopy is an interesting part of a kitchen because it sits at the meeting point of two different cleaning jobs. On one side is the general kitchen deep clean, which addresses the kitchen's surfaces, equipment and fabric - including the canopy as a visible, greasy surface in the kitchen. On the other is specialist extract cleaning, which addresses the extract system - the ductwork and fan - to a fire-safety standard. The canopy is where these two meet, because it is both a kitchen surface and the entrance to the extract system.
That dual position causes real confusion about what is covered by what. Because the canopy is part of what a deep clean cleans, it is easy to assume a deep clean has dealt with the extract - but the extract system behind the canopy is a separate job the deep clean does not do. Understanding the canopy as a boundary, not a single thing covered by one clean, is the key to knowing what your deep clean actually addresses on it and what remains for the specialist extract clean. The canopy is where you have to be clear about which job covers what.
What the deep clean covers
A general kitchen deep clean addresses the canopy as a visible, accessible part of the kitchen. That means cleaning the canopy's external and accessible surfaces - the parts you can see and reach - which accumulate grease like any surface near the cookline, and often the baffle filters, which are removable and washable. So a deep clean does genuinely clean the canopy in the sense of the surfaces and filters that are part of the accessible kitchen environment, returning them to a clean state as part of resetting the kitchen.
This is real and valuable work - the canopy is one of the greasiest visible parts of a kitchen, and cleaning its surfaces and filters is part of a proper deep clean. But it is important to see the limit of it: the deep clean addresses the canopy as an accessible kitchen surface, up to where the accessible surfaces end. What lies beyond - the extract system the canopy feeds into - is not part of the general deep clean, because it is a different job requiring different access, methods and standards. The deep clean covers the visible canopy; the boundary is where the visible ends.
What is separate
What is separate from the deep clean is the extract system that the canopy feeds - the plenum, ductwork and fan behind and beyond the canopy. This is specialist extract cleaning, and it differs from the general deep clean in fundamental ways. It addresses the enclosed, sealed parts of the system that the deep clean cannot reach; it is done to the TR19 Grease fire-safety standard, with measured verification; and it exists specifically to control the fire risk of grease building up in the ductwork and fan, which is a different concern from the general hygiene of cleaning the kitchen's surfaces.
So the extract system is not a deeper part of the same deep clean but a distinct job with its own standard, methods and purpose. It requires access into the sealed ductwork, cleaning of the whole enclosed run, and verification to the fire-safety standard - none of which a general deep clean does. The grease that passes the canopy and filters into the ductwork and fan is addressed by this separate extract clean, not by the deep clean of the visible canopy. Recognising the extract system as a separate job is what stops a deep clean being mistaken for having dealt with the whole extract.
Why the distinction matters
The distinction matters because assuming a deep clean has dealt with the extract leaves the real fire risk unaddressed. A deep clean can leave the canopy surfaces and filters looking clean while the ductwork and fan behind them are grease-laden and uncleaned - because the deep clean did the visible canopy but not the separate extract clean. A clean-looking canopy is therefore not evidence of a clean extract system, and treating it as such is exactly how the fire risk in the ductwork gets overlooked.
So the practical point is to be clear that both jobs need doing, and that the deep clean of the visible canopy does not substitute for the specialist extract clean of the system behind it. A kitchen needs its canopy surfaces and filters kept clean - part of the deep clean and daily cleaning - and its extract system cleaned to the fire-safety standard on its own cycle. The canopy boundary is where these two responsibilities meet, and knowing that the deep clean stops at the visible canopy is what ensures the extract system behind it gets the separate clean it needs.
The takeaway
The canopy sits at the boundary between a general kitchen deep clean and specialist extract cleaning. The deep clean addresses the canopy's visible, accessible surfaces and often its filters, as part of cleaning the kitchen - real, valuable work on one of the greasiest visible parts of the kitchen. But it stops where the accessible surfaces end.
Behind the canopy, the extract system - ductwork and fan - is a separate, specialist job, cleaned to the TR19 Grease fire-safety standard with measured verification, addressing the enclosed parts the deep clean cannot reach and the fire risk it does not cover. So a clean-looking canopy is not a clean extract system, and the deep clean does not substitute for the extract clean. Knowing where the deep clean ends and the extract clean begins - at the canopy - is what ensures both get done, and the fire risk behind the canopy is not left because the front looked clean.
Questions
No - it covers the canopy's visible, accessible surfaces and often its filters, as part of cleaning the kitchen. The extract system behind the canopy - the ductwork and fan - is a separate, specialist job to the TR19 fire-safety standard that the deep clean does not do.
It cleans the canopy's external and accessible surfaces, which accumulate grease like any surface near the cookline, and often the baffle filters, which are removable and washable - returning them to a clean state as part of resetting the kitchen. It addresses the canopy up to where the accessible surfaces end.
The extract system the canopy feeds - the plenum, ductwork and fan. This is specialist extract cleaning, done to the TR19 Grease fire-safety standard with measured verification, addressing the enclosed parts the deep clean cannot reach and the fire risk it does not cover.
Because it addresses sealed, enclosed ductwork the deep clean cannot reach, is done to a fire-safety standard with verification, and exists to control the fire risk of grease in the ductwork and fan - a different concern, standard and method from cleaning the kitchen's visible surfaces.
No. A deep clean can leave the canopy surfaces and filters looking clean while the ductwork and fan behind them are grease-laden and uncleaned. A clean-looking canopy is not evidence of a clean extract system - which is how the fire risk in the ductwork gets overlooked.
Yes. The canopy surfaces and filters need keeping clean as part of the deep clean and daily cleaning, and the extract system behind needs cleaning to the fire-safety standard on its own cycle. The deep clean of the visible canopy does not substitute for the specialist extract clean.
We clean the extract system behind the canopy to the TR19 Grease standard - the specialist, verified job on the ductwork and fan that a general deep clean of the visible canopy does not cover.
