Inspectors check the places routine cleaning skips. Here are the blind spots behind, under, above and inside your equipment that decide your structure and cleanliness marks.
The short answer
Surfaces you wipe every shift are rarely where marks are lost. Environmental Health Officers are trained to check the places routine cleaning skips - behind, under, above and inside equipment - because that is where soil, grease and pests actually build up.
Under the Food Hygiene Rating Scheme, the cleanliness and condition of your premises is one of three scored areas. An officer assesses it on what they can see and reach during an unannounced visit, and they know the kitchen's blind spots better than most operators do. Here is where they look, and why.
The blind spots
Ranges, fryers, griddles, fridges and prep benches are heavy, so they rarely get moved - and the gap behind and the floor beneath them collect grease, food debris and standing soil. Officers will look down the sides, behind, and underneath wherever access allows. Wall-to-equipment junctions, the splash zone behind fryers and ranges, and equipment feet and castors are classic mark-losers because grease bakes on and becomes a cleaning and pest issue at once.
Up high and inside
High-level surfaces - tops of units, ledges, pipework, ceiling fixtures and lighting diffusers - gather grease-laden dust that drifts down onto food areas. Officers notice it because it signals the cleaning routine stops at eye level. The extraction system is firmly on their radar too: grease-coated canopy filters, residue around the fan housing, or grease weeping from duct joints are immediate red flags, and they need no special equipment to spot them. An officer can also ask to see your TR19 grease certificate as documentary proof the system has been cleaned to standard and at the right frequency - an absent or out-of-date certificate gets noted.
Then there are the interiors: the inside of ovens and combi units, extraction plenums, ice machines, drains and gulleys, and waste areas. These are exactly the zones a deep clean is designed to reach and a daily clean is not. Getting them right is less about effort on the day and more about a periodic deep clean that resets the parts of the kitchen an inspector knows to check.
Questions
They check behind and underneath wherever access reasonably allows - down the sides of the cookline, under benches, behind fridges. Heavy fixed equipment may not be moved, but visible grease and debris in the gaps still counts against you, which is why a periodic deep clean that reaches those zones matters.
Yes. Ventilation sits within the structure and cleanliness assessment. Grease-coated filters, residue around the fan, or grease dripping from duct joints are immediate red flags, and an officer can ask to see your TR19 grease cleaning certificate as proof of maintenance.
Soiled door gaskets and dust-clogged condenser coils are common findings. They are both a hygiene issue and a performance one, since a dirty seal or coil makes the unit work harder and hold temperature less reliably.
Grease-laden dust on tops of units, ledges, pipework and light fittings drifts down onto food areas, and it signals to an officer that the cleaning routine stops at eye level. High-level surfaces are a frequent and avoidable mark-loser.
Daily surfaces, yes. The baked-on grease behind the cookline, the extraction interior, high-level surfaces and equipment interiors usually need a periodic professional deep clean with the right access and chemicals - and the dated evidence to show it was done.
It depends on cooking type and hours, but high-grease kitchens typically need the hidden and high-level areas reset on a planned cycle rather than left until an inspection looms. We can advise an interval for your kitchen.
