Restaurant and Kitchen Cleaning in London: What Your EHO Inspector Actually Looks For

Your Food Hygiene Rating is public. Anyone in London can check it before they walk through your door. A score of 5 tells customers your restaurant takes food safety seriously. A score of 3 suggests room for improvement. A score of 1 or 0 can end a restaurant before its next review cycle even arrives.

Environmental Health Officers from your local London borough council conduct unannounced inspections and score your premises across three categories: hygienic food handling, cleanliness and condition of facilities, and confidence in management. Cleaning affects all three. It is not a separate line item. It is woven into every aspect of the inspection, and EHOs are trained to see what you have missed.

The problem for many London restaurant owners is that they clean diligently every day but still lose marks on inspection. That happens because there is a gap between what most kitchens consider "clean" and what an EHO considers compliant. This guide closes that gap. It explains exactly what inspectors look for, where restaurants most commonly fail on cleaning, and what a professional kitchen deep clean should cover to protect your rating.

How the Food Hygiene Rating Scheme Scoring Works for London Restaurants

Before understanding what to clean, it helps to understand how the scoring works. The Food Hygiene Rating Scheme (FHRS) runs from 0 to 5. It is not scored out of 5 in the way most people assume. It is scored on a points system where lower points mean a higher rating.

EHOs assess your premises across three categories and assign points based on the severity of any issues found.

Hygienic food handling covers how food is prepared, cooked, reheated, cooled, and stored. This includes whether cross-contamination controls are in place, whether food is stored at correct temperatures, and whether allergen management procedures are followed. Cleaning is directly relevant here because dirty preparation surfaces, contaminated chopping boards, and unclean storage containers all indicate poor food handling hygiene.

Cleanliness and condition of facilities and building is the most directly cleaning-related category. It covers the physical state of the kitchen, dining area, washrooms, storage areas, and any outdoor spaces used for food preparation or waste. The inspector assesses whether the layout supports good hygiene, whether ventilation and handwashing facilities are adequate, whether pest control is in place, and whether the premises is clean to a standard that prevents contamination.

Confidence in management assesses whether you have systems and checks in place to ensure food safety is maintained consistently. This includes documentation such as Safer Food, Better Business (SFBB) records, cleaning schedules, temperature logs, and staff training records. A clean kitchen on the day of inspection is good. A clean kitchen supported by documented cleaning schedules and signed-off daily checklists tells the EHO that standards are maintained consistently, not just when someone suspects an inspection might be coming.

A total score of fewer than 15 points earns a rating of 5. A score of 15 to 20 earns a 4. A score of 25 to 30 earns a 3. Once you reach 35 points or above, you are in the territory of ratings 2, 1, or 0, all of which carry serious reputational and potentially legal consequences.

The Specific Cleaning Areas EHO Inspectors Check in London Restaurant Kitchens

EHOs follow a systematic approach. They do not just glance around and form an impression. They check specific areas, and they check behind, underneath, and inside equipment that your kitchen team may not touch during daily cleaning. Here is what they look at.

Extraction canopies, filters, and ductwork. This is one of the first things an experienced EHO and fire safety assessor will check. Grease build-up in extraction systems is both a hygiene risk and a fire risk. Canopy filters should be cleaned weekly regardless of throughput. The canopy hood, plenums, and ductwork require periodic deep cleaning to TR19 standards, typically every six to twelve months depending on cooking volume. If your filters are visibly greasy, if there is fat accumulation on the canopy hood, or if your ductwork has not been professionally cleaned with dated reports to prove it, you will lose marks.

Behind and underneath cooking equipment. EHOs will look behind fryers, ovens, ranges, and combi steamers. They will check underneath prep tables, refrigeration units, and dishwashers. These are areas where grease, food debris, and moisture accumulate, creating ideal conditions for bacterial growth and pest activity. If your kitchen team only cleans what they can see without moving equipment, these areas will fail inspection.

Walk-in fridges and cold storage. Inspectors check the interior walls, floors, shelving, and door seals of walk-in fridges and cold rooms. They look for mould, condensation, spilled liquids, and food debris. They check that raw and cooked foods are separated correctly, that items are labelled and dated, and that the unit itself is clean enough to prevent contamination. A clean fridge interior demonstrates that food storage is being managed hygienically.

Handwashing facilities. Every food preparation area must have a dedicated handwashing station with hot and cold running water, soap, and hygienic drying (paper towels or air dryer, not a shared cloth). The EHO will check that the basin is clean, that soap is stocked, that drying facilities are available, and that the station is not being used for any other purpose such as washing equipment or food. A blocked, dirty, or poorly stocked handwash basin is one of the most common reasons for lost marks in London restaurants.

Food contact surfaces and chopping boards. All surfaces that come into contact with food must be clean, in good condition, and free from damage that could harbour bacteria. Chopping boards should be colour-coded to prevent cross-contamination (red for raw meat, blue for raw fish, green for salad and fruit, yellow for cooked meat, brown for vegetables, white for dairy and bakery). Worn, scored, or stained boards should be replaced. The EHO will also check that sanitiser is available and being used correctly at food contact surfaces.

Floors, walls, and ceilings. Kitchen floors must be clean, in good repair, and made of a material that can be effectively cleaned. Cracked tiles, damaged grout, and lifting flooring are flagged because they harbour bacteria and are impossible to clean properly. Walls behind cooking stations should be free from grease splatter. Ceilings should be free from condensation, mould, and flaking paint. These are areas that daily cleaning often does not reach thoroughly enough.

Waste and bin areas. Waste bins must be lidded, regularly emptied, and cleaned. Bin areas, both internal and external, should be clean, tidy, and free from overflowing waste. External bin stores must be kept clean enough to prevent pest activity. The EHO will check that food waste is being separated where required and that waste disposal procedures are documented.

Pest prevention. While pest control is not strictly a cleaning issue, it is closely related. A dirty kitchen attracts pests. The EHO will look for signs of pest activity including droppings, gnaw marks, nesting material, and live or dead pests. They will check that entry points are sealed, that electronic fly killers are positioned correctly (not above food preparation areas), and that you have a contracted pest control service with current inspection reports on file.

Washrooms and staff facilities. Customer toilets and staff changing areas must be clean, ventilated, and properly maintained. These areas reflect the overall hygiene culture of the business. If the customer washroom is dirty, the EHO will assume the kitchen is not much better.

The Most Common Cleaning Failures in London Restaurant EHO Inspections

Certain cleaning failures appear repeatedly in London restaurant inspections. Knowing what they are means you can address them before an inspector finds them.

No documented cleaning schedule. Many London restaurants clean thoroughly but have no written schedule showing what is cleaned, how often, by whom, and with what products. The EHO needs to see a documented cleaning schedule that covers every area of the kitchen and front of house, with sign-off records showing it is being followed. Without documentation, even a spotless kitchen loses marks under "confidence in management" because the inspector has no evidence that standards are maintained consistently.

Extraction systems not professionally maintained. Daily filter cleaning is not enough. The entire extraction system, from canopy to ductwork to fan to discharge grille, needs periodic professional deep cleaning. The EHO will ask when it was last cleaned and may ask to see TR19 cleaning reports. If you cannot produce them, you lose marks.

Grease accumulation behind equipment. This is the single most common cleaning failure in commercial kitchens. The front and top of equipment gets cleaned daily, but behind the fryer, under the prep bench, and the gap between the range and the wall are forgotten. EHOs look there specifically because that is where they find problems.

Handwash stations not properly maintained. Missing soap, no paper towels, a basin used for rinsing equipment, or a tap that only runs cold water. Any of these will cost you marks.

Damaged surfaces treated as a cleaning issue rather than a maintenance issue. Cracked floor tiles, damaged wall cladding, and worn chopping boards cannot be cleaned to a safe standard. The EHO is not looking for clean damage. They are looking for surfaces that are both clean and in good enough condition to be cleaned effectively. If the surface is compromised, cleaning alone will not solve the problem.

Inconsistent standards between front of house and kitchen. Some restaurants maintain a spotless dining room but allow the kitchen to slip. Others have an immaculate kitchen but neglect customer washrooms. The EHO assesses the whole premises. Inconsistency between areas suggests that hygiene is treated as an aesthetic concern rather than a safety discipline.

Daily, Weekly, and Monthly Kitchen Cleaning Schedule for London Restaurants

A structured cleaning schedule is essential for maintaining standards between professional deep cleans and for providing the documentation that EHOs want to see.

Daily cleaning tasks (end of every service). Clean and sanitise all food preparation surfaces, chopping boards, and utensils. Wipe down all cooking equipment exteriors including ranges, fryers, ovens, and grills. Clean and restock handwashing stations. Sweep and mop all kitchen floors. Empty all bins and replace liners. Wipe down door handles, light switches, and high-touch surfaces. Clean the pass and any service counters. Check and clean dishwasher filters. Wipe down fridges externally and check for spills internally.

Weekly cleaning tasks. Deep clean extraction canopy filters (soak and degrease). Pull out accessible equipment and clean behind and underneath. Deep clean walk-in fridges and cold rooms including walls, floors, shelving, and door seals. Clean and descale sinks and taps. Wipe down walls behind cooking stations. Clean all drainage channels and floor gullies. Deep clean fryers (boil out). Clean and sanitise ice machines.

Monthly cleaning tasks. Deep clean ovens and combi steamers (full strip-down where possible). Clean ceiling vents and extractor grilles. Deep clean dry stores and check for pest activity. Clean behind fixed equipment that is not moved weekly. Inspect and clean grease traps. Review and restock cleaning chemicals and supplies.

Quarterly or biannual (professional deep clean). Full extraction system deep clean to TR19 standards including canopy, ductwork, fan, and discharge. Full kitchen deep clean including high-level surfaces, behind all equipment, floor drains, wall tiles, and ceiling. Professional carpet or hard floor cleaning in front-of-house areas. This is the level of cleaning that should be carried out by a professional commercial cleaning company with experience in hospitality environments.

Why Professional Kitchen Deep Cleaning Matters for Your Food Hygiene Rating

Daily cleaning by your kitchen team is essential, but it is not sufficient on its own. Kitchen staff clean around their working environment every day, but they do not have the time, equipment, or products to reach everything that accumulates over weeks and months. Grease builds up inside ductwork that is inaccessible without specialist equipment. Carbon deposits form inside ovens and on equipment components that need dismantling to clean properly. Biofilm develops in drains and on surfaces that look clean to the eye but are not hygienically safe.

A professional kitchen deep clean addresses everything that daily cleaning cannot. It uses commercial-grade degreasing agents, high-temperature steam, and specialist extraction cleaning equipment that is not available to in-house teams. It reaches areas that are physically inaccessible during daily service. And critically, it produces dated reports, photographs, and certificates that provide the documented evidence EHOs look for under "confidence in management."

The frequency of professional deep cleaning depends on your kitchen's throughput. High-volume restaurants serving 200 or more covers per day should schedule quarterly deep cleans. Medium-volume restaurants can typically maintain standards with biannual deep cleaning. Lower-volume cafes and smaller kitchens may need professional cleaning once or twice a year. Extraction systems should be cleaned to TR19 standards every six to twelve months regardless of volume.
