Kitchen deep cleaning - hygiene ratings
A kitchen can look clean on the surface - wiped worktops, mopped floors - and still not be clean where it counts. A food hygiene inspection checks behind, under and inside equipment, and in the extraction, where hidden grease and dirt build up. So looks clean and scores clean are different, and genuine cleanliness is what earns the rating. Here is why. This is general information.
The short answer
There is an important difference between a kitchen looking clean and a kitchen being clean where it counts for the food hygiene rating - between looks clean and scores clean. Looks clean is surface tidiness: the visible surfaces are wiped, the floors are mopped, the kitchen looks presentable at a glance - the surface appearance is clean. Scores clean is genuine, thorough cleanliness: the kitchen is actually clean throughout, including the hidden and hard-to-reach areas, so it stands up to proper scrutiny. The two are different because surface cleaning can make a kitchen look clean while leaving hidden dirt untouched - and a food hygiene inspection looks beyond the surface. An inspector (environmental health) checking the kitchen's cleanliness does not just look at the visible surfaces; they check the hidden and hard-to-reach areas where dirt builds up out of sight: behind and under equipment (where food debris, grease and dirt accumulate), inside equipment (ovens, fryers, and the like), the extraction system (where grease builds up), and other areas that surface cleaning misses. So the inspection assesses genuine cleanliness, not just surface appearance - and a kitchen that looks clean but has hidden grease and dirt in these areas does not score as well as it looks, because the inspector finds what the surface cleaning left. This is why looks clean and scores clean differ: the rating reflects genuine cleanliness (including the hidden areas), not the surface appearance, so a kitchen has to be clean where it counts - not just where it shows - to score well. The gap between them is the hidden grease and dirt: the build-up in the behind/under/inside areas and the extraction that surface cleaning does not reach, but that the inspection does check and that harms the rating. Closing that gap - making scores clean match looks clean - requires thorough cleaning that reaches the hidden areas, and in particular periodic deep cleaning, which reaches the built-up grease and debris in equipment, extraction and hard-to-reach areas that routine surface cleaning misses. So the way to score clean, not just look clean, is genuine thorough cleaning (including the hidden areas) and periodic deep cleaning to reach the build-up - so the kitchen is clean where the inspection checks, not just where it shows. So looks clean is not enough; scores clean requires genuine cleanliness, reached by thorough and deep cleaning. This is general information; follow the food hygiene rating scheme for your situation.
Key points
Two kinds of clean
The key distinction is between two kinds of clean: looks clean (surface tidiness) and scores clean (genuine cleanliness). Looks clean means the kitchen looks clean on the surface - the visible surfaces are wiped, the floors are mopped, the kitchen is tidy and presentable at a glance. This is real cleaning as far as it goes (the surfaces are cleaned), and it makes the kitchen look clean. Scores clean means the kitchen is genuinely clean throughout - not just the visible surfaces, but the hidden and hard-to-reach areas too, so it is actually clean where it counts and stands up to proper scrutiny. The difference is that looks clean is about the surface appearance, while scores clean is about genuine, thorough cleanliness including the hidden areas.
These two can come apart because surface cleaning can make a kitchen look clean while leaving hidden dirt untouched. A kitchen can have its visible surfaces wiped and floors mopped (so it looks clean) while grease and dirt build up unseen behind and under equipment, inside equipment, and in the extraction - areas that surface cleaning does not reach. So a kitchen can look clean (surface tidiness) without being clean where it counts (genuine cleanliness) - the two diverge when surface cleaning is done but the hidden areas are neglected. This matters for the food hygiene rating because, as the next section covers, the inspection checks the hidden areas - so it is scores clean (genuine cleanliness), not looks clean (surface tidiness), that earns the rating. Understanding that these are two different things - and that a kitchen can be one without the other - is the key point: looking clean is not the same as being clean where the inspection checks. So the distinction between surface tidiness and genuine cleanliness is what this is about, and it is genuine cleanliness that counts for the rating. This is general information.
What the inspector checks
The reason genuine cleanliness matters (not just surface appearance) is that a food hygiene inspection checks the hidden and hard-to-reach areas, not just the visible surfaces. An inspector (environmental health officer) assessing the kitchen's cleanliness looks beyond the surface tidiness to the areas where dirt builds up out of sight - because these are where hygiene problems hide, and genuine cleanliness has to include them. The areas an inspector typically checks include: behind and under equipment (where food debris, grease and dirt accumulate out of sight - a classic place for hidden build-up); inside equipment (ovens, fryers, and other equipment, where grease and soil build up); the extraction system (canopy, filters, and the ductwork behind, where grease builds up - a fire risk as well as a hygiene one); and other hard-to-reach areas (gaps, corners, under and behind fittings). So the inspection reaches into the places surface cleaning misses.
This is why a kitchen that looks clean but has hidden grease and dirt in these areas does not score as well as it looks - the inspector finds what the surface cleaning left. An inspector checking behind and under the equipment, inside the ovens, and the state of the extraction, will find the hidden build-up if it is there, and it counts against the rating (indicating the kitchen is not genuinely clean, whatever the surfaces look like). So the inspection assesses genuine cleanliness, including the hidden areas - which is exactly why looks clean and scores clean differ: the surface appearance is not what is (solely) assessed; the genuine cleanliness, including the checked hidden areas, is. So the inspector's checking of the hidden areas is what makes genuine cleanliness (not surface tidiness) the thing that scores. This means, to score well, the kitchen has to be clean in these hidden and hard-to-reach areas - behind, under and inside equipment, and in the extraction - not just on the visible surfaces. So knowing what the inspector checks (the hidden areas) shows what scores clean requires (genuine cleanliness in those areas). So the inspection reaches beyond the surface, which is why genuine cleanliness is what counts. This is general information; what an inspector checks is covered further in related guidance.
The gap
The gap between looks clean and scores clean is the hidden grease and dirt - the build-up in the areas surface cleaning misses but the inspection checks. When a kitchen looks clean but does not score as clean as it looks, the difference is the hidden build-up: the grease and dirt that accumulate behind, under and inside equipment and in the extraction, out of sight, which surface cleaning (wiping visible surfaces, mopping floors) does not reach. This build-up grows over time as the kitchen operates (grease from cooking, food debris, soil) in the places routine surface cleaning does not get to - so even a kitchen kept looking clean on the surface accumulates hidden grease and dirt in these areas, creating the gap between how clean it looks and how clean it actually is where the inspection checks.
This hidden build-up is what harms the rating despite the clean surfaces - it is what the inspector finds behind and under and inside the equipment and in the extraction, and it counts against the genuine cleanliness the rating assesses. So the gap is not just theoretical: it is real hidden dirt that a surface-clean kitchen accumulates and that the inspection reveals. And it is worth noting this hidden grease (especially in the extraction) is also a fire risk and can harbour pests - so it matters beyond the rating too. Closing the gap - making the kitchen scores clean, matching how it looks - means dealing with this hidden build-up: cleaning the areas surface cleaning misses (behind, under and inside equipment, the extraction), so the kitchen is genuinely clean where it counts, not just where it shows. This is where thorough and deep cleaning come in (covered next) - reaching the hidden build-up to close the gap. So the gap between looks clean and scores clean is the hidden grease and dirt, and closing it means cleaning the hidden areas the surface cleaning leaves. So understand the gap - hidden build-up - and address it to score clean, not just look clean. This is general information.
Closing the gap
Closing the gap between looks clean and scores clean - making the kitchen genuinely clean where it counts - requires thorough cleaning that reaches the hidden areas, and in particular periodic deep cleaning. Thorough routine cleaning: good routine cleaning should go beyond the visible surfaces to include the hidden and hard-to-reach areas as far as practicable - cleaning behind and under equipment (moving equipment to clean behind/under where possible), cleaning inside equipment, and generally not just doing the surfaces. A cleaning regime that includes the hard-to-reach areas (through a proper cleaning schedule covering them, not just wiping surfaces) keeps more of the hidden dirt down, narrowing the gap. So thorough routine cleaning - reaching beyond the surfaces - is part of closing the gap.
Periodic deep cleaning: some build-up accumulates in places and to a degree that routine cleaning does not fully address - the built-up grease and soil inside equipment, in the extraction system, and in the hard-to-reach areas - so periodic deep cleaning is what reaches and removes this. Deep cleaning is a thorough, comprehensive clean that tackles the built-up grease and dirt in the equipment, extraction and hard-to-reach areas that routine surface cleaning misses - so it reaches into exactly the hidden areas the inspection checks and removes the build-up that creates the gap. So periodic deep cleaning is central to closing the gap: it makes the hidden areas genuinely clean, so the kitchen scores clean (not just looks clean). The extraction system especially needs deep cleaning (routine cleaning cannot reach the grease in the ductwork), and it is both a hygiene and a fire-safety matter. So the way to score clean, not just look clean, is thorough routine cleaning (reaching beyond the surfaces) plus periodic deep cleaning (reaching the built-up hidden grease and dirt in equipment, extraction and hard-to-reach areas) - so the kitchen is genuinely clean where the inspection checks, closing the gap between how it looks and how it scores. So close the gap with thorough and deep cleaning, making genuine cleanliness match the surface appearance. This is where deep cleaning connects to the rating: it reaches the hidden build-up that surface cleaning leaves, making the kitchen scores clean. This is general information.
Clean where it counts
So looks clean and scores clean are different: a kitchen can look clean on the surface (wiped surfaces, mopped floors) while hidden grease and dirt build up behind, under and inside equipment and in the extraction - and because a food hygiene inspection checks these hidden areas, it is genuine cleanliness (scores clean), not surface tidiness (looks clean), that earns the rating. The gap between them is the hidden build-up that surface cleaning misses but the inspection checks, and closing it - making the kitchen genuinely clean where it counts - requires thorough cleaning that reaches the hidden areas and periodic deep cleaning that removes the built-up grease and dirt. So the lesson is that surface cleaning is not enough for the rating: the kitchen has to be clean where the inspection checks (the hidden areas), not just where it shows.
This matters practically because it is easy to be lulled by a kitchen that looks clean into thinking it will score well, when the hidden build-up tells a different story to an inspector. So a kitchen aiming to score well should ensure it is genuinely clean - including the hidden and hard-to-reach areas the inspection checks - through a thorough cleaning regime and periodic deep cleaning, not rely on surface tidiness. This is where thorough and deep cleaning earn their place: they make the kitchen genuinely clean where it counts, so it scores as clean as it looks. And the deep cleaning, by reaching the hidden grease (especially in the extraction), also addresses the fire-safety and pest aspects of that build-up, not just the rating. So to score clean, not just look clean, keep the kitchen genuinely clean throughout - surfaces and hidden areas - with thorough routine cleaning and periodic deep cleaning, so it is clean where the inspection checks. So genuine cleanliness, reached by thorough and deep cleaning, is what earns the rating - looks clean is not enough. This is where our deep cleaning connects to your rating: reaching the hidden build-up that surface cleaning leaves, so the kitchen is genuinely clean where it counts. This is general information; follow the food hygiene rating scheme for your situation.
Questions
Looks clean is surface tidiness - the visible surfaces wiped, the floors mopped, the kitchen presentable at a glance, so it looks clean on the surface. Scores clean is genuine, thorough cleanliness - the kitchen actually clean throughout, including the hidden and hard-to-reach areas, so it stands up to proper scrutiny and earns a good hygiene rating. The two are different because surface cleaning can make a kitchen look clean while leaving hidden dirt untouched: a kitchen can have its visible surfaces wiped and floors mopped (so it looks clean) while grease and dirt build up unseen behind and under equipment, inside equipment, and in the extraction - areas surface cleaning does not reach. So a kitchen can look clean without being clean where it counts. This matters for the food hygiene rating because the inspection checks the hidden areas - so it is scores clean (genuine cleanliness), not looks clean (surface tidiness), that earns the rating. So the two are different, and it is genuine cleanliness, not surface appearance, that counts for the rating. This is general information.
Because a food hygiene inspection checks the hidden and hard-to-reach areas, not just the visible surfaces - so hidden grease and dirt count against the rating even if the surfaces look clean. An inspector assessing cleanliness looks beyond the surface tidiness to where dirt builds up out of sight: behind and under equipment (where food debris, grease and dirt accumulate), inside equipment (ovens, fryers), the extraction system (where grease builds up), and other hard-to-reach areas. So a kitchen that looks clean on the surface but has hidden grease and dirt in these areas does not score as well as it looks - the inspector finds what the surface cleaning left, and it counts against the genuine cleanliness the rating assesses. So the rating reflects genuine cleanliness (including the hidden areas), not the surface appearance. This is why a clean-looking kitchen can still score poorly: the inspection reaches the hidden build-up that surface cleaning missed. So to score well, the kitchen has to be genuinely clean where the inspection checks - the hidden areas too - not just look clean on the surface. This is general information.
The areas where dirt builds up out of sight, which surface cleaning misses: behind and under equipment (where food debris, grease and dirt accumulate - a classic place for hidden build-up); inside equipment (ovens, fryers, and other equipment, where grease and soil build up); the extraction system (canopy, filters, and the ductwork behind, where grease builds up - a fire risk as well as a hygiene one); and other hard-to-reach areas (gaps, corners, under and behind fittings). An inspector checking the kitchen's cleanliness reaches into these places, because they are where hygiene problems hide and genuine cleanliness has to include them - so they check behind and under the equipment, inside the ovens, and the state of the extraction, and will find hidden build-up if it is there. So the inspection assesses genuine cleanliness including these hidden areas, which is why they matter for the rating. This means, to score well, the kitchen has to be clean in these hidden and hard-to-reach areas, not just on the visible surfaces. So the inspector reaches beyond the surface, which is why keeping the hidden areas genuinely clean matters for the rating. This is general information; related guidance covers what an inspector checks in more detail.
The hidden grease and dirt - the build-up in the areas surface cleaning misses but the inspection checks. When a kitchen looks clean but does not score as clean as it looks, the difference is the hidden build-up: grease and dirt that accumulate behind, under and inside equipment and in the extraction, out of sight, which surface cleaning (wiping visible surfaces, mopping floors) does not reach. This build-up grows over time as the kitchen operates (grease from cooking, food debris, soil) in the places routine surface cleaning does not get to - so even a kitchen kept looking clean on the surface accumulates hidden grease and dirt in these areas, creating the gap between how clean it looks and how clean it actually is where the inspection checks. This hidden build-up is what harms the rating despite the clean surfaces, and it is also a fire risk (especially in the extraction) and can harbour pests. So the gap is real hidden dirt that a surface-clean kitchen accumulates and the inspection reveals. Closing it means cleaning the areas surface cleaning misses, so the kitchen is genuinely clean where it counts. This is general information.
Through thorough cleaning that reaches the hidden areas, and in particular periodic deep cleaning. Thorough routine cleaning: good routine cleaning should go beyond the visible surfaces to include the hidden and hard-to-reach areas as far as practicable - cleaning behind and under equipment (moving equipment where possible), cleaning inside equipment, not just doing the surfaces - through a proper cleaning schedule covering these areas. This keeps more of the hidden dirt down. Periodic deep cleaning: some build-up accumulates to a degree routine cleaning does not fully address - the built-up grease and soil inside equipment, in the extraction, and in hard-to-reach areas - so periodic deep cleaning reaches and removes it. Deep cleaning is a thorough, comprehensive clean tackling the built-up grease and dirt in equipment, extraction and hard-to-reach areas that routine surface cleaning misses - reaching exactly the hidden areas the inspection checks. So thorough routine cleaning (beyond the surfaces) plus periodic deep cleaning (reaching the built-up hidden grease and dirt) make the kitchen genuinely clean where the inspection checks, closing the gap between how it looks and how it scores. The extraction especially needs deep cleaning. So genuine thorough and deep cleaning is how you score clean, not just look clean.
No - surface cleaning is not enough, because the inspection assesses genuine cleanliness including the hidden areas, not just the surface appearance. A kitchen kept looking clean on the surface (wiped surfaces, mopped floors) still accumulates hidden grease and dirt behind, under and inside equipment and in the extraction, and the inspection checks these areas - so surface cleaning alone leaves the hidden build-up that harms the rating. It is easy to be lulled by a kitchen that looks clean into thinking it will score well, when the hidden build-up tells a different story to an inspector. So a kitchen aiming to score well should ensure it is genuinely clean - including the hidden and hard-to-reach areas the inspection checks - through a thorough cleaning regime and periodic deep cleaning, not rely on surface tidiness. The deep cleaning, by reaching the hidden grease (especially in the extraction), also addresses the fire-safety and pest aspects of that build-up, not just the rating. So surface cleaning is not enough; genuine cleanliness, reached by thorough and deep cleaning, is what earns the rating. Keep the kitchen genuinely clean throughout - surfaces and hidden areas - so it is clean where the inspection checks. This is general information.
The gap between looks clean and scores clean is the hidden grease and dirt behind, under and inside equipment and in the extraction. Our kitchen deep cleaning and extraction cleaning reach and remove that build-up, so the kitchen is genuinely clean where the inspection checks. Ask us about a thorough deep clean.
