TR19 Compliant Ventilation & Kitchen Extract Cleaning — Scotland-Wide
Commercial Kitchen Deep Cleaning
Kitchen deep cleaning is one of the most important — and most overlooked — fire safety and hygiene obligations in any commercial catering operation. While extract systems rightly receive attention, dirty cooking equipment is often an equal or greater source of ignition.
Deep Clean Scotland provides full commercial kitchen deep cleaning services across Scotland — thorough decarbonising and degreasing of all equipment, surfaces, and hard-to-reach areas, with complete documentation on every visit.
The Fire Risk That's Often Overlooked
The focus in commercial kitchen fire safety is frequently placed on extract ductwork and canopy systems — and rightly so. But the cooking equipment itself is often an equal or greater source of ignition. Grease and carbon deposits that accumulate on and inside ovens, fryers, grills, and ranges are highly combustible. A fryer fire or oven fire that might otherwise be contained can rapidly escalate when surrounding surfaces are coated in built-up grease.
The relationship between equipment cleanliness and extract system safety is direct: a dirty kitchen produces more airborne grease, which accelerates the rate of deposit build-up in the canopy and ductwork above. If a fire starts at the equipment level and the extract system is contaminated, the ductwork becomes a channel through which fire can spread rapidly throughout the building — well beyond the kitchen itself.
Under the Food Hygiene (Scotland) Regulations 2006, food business operators are required to keep all equipment, surfaces, and fittings clean and, where necessary, disinfected. This is not optional — failure to maintain a clean kitchen is a breach of food hygiene law and can result in improvement notices, prohibition orders, and prosecution by the local authority.
Regular deep cleaning also has a direct impact on your food hygiene rating. Environmental Health Officers assess cleanliness as a core component of any inspection — a poorly maintained kitchen will result in a lower rating, which is now publicly displayed and directly affects customer confidence.
Beyond safety and compliance, there is a significant operational benefit that is frequently underestimated: equipment longevity. Grease and carbon build-up forces equipment to work harder, increases operating temperatures, and accelerates wear on components. Regular deep cleaning removes these deposits, restores equipment to its designed operating efficiency, reduces energy consumption, and meaningfully extends the working life of ovens, fryers, grills, and ranges — deferring costly replacement and reducing the frequency of breakdowns during service.

What We Can Include
Every kitchen is different. Scope is agreed at survey stage based on your equipment, layout, and cleaning frequency requirements.
Canopy & Filter Cleaning is a separate service
Extraction canopies, grease filters, and plenum chambers are covered under our dedicated Canopy & Filter Cleaning service — carried out to TR19 benchmark grease deposit levels with a compliance certificate issued on completion.
Your Legal Obligations
Requires food business operators to keep all equipment, surfaces, and fittings clean and, where necessary, disinfected. Failure to comply can result in improvement notices, prohibition orders, and prosecution.
The Responsible Person must take general fire precautions and ensure the premises are safe. Accumulated grease on cooking equipment is a recognised fire hazard that must be controlled as part of the fire risk assessment.
Employers must provide and maintain a safe working environment. A kitchen with heavy grease and carbon build-up on equipment presents a direct risk to kitchen staff.

Frequently Asked Questions
How often should a commercial kitchen be deep cleaned?
The Food Hygiene (Scotland) Regulations 2006 require food businesses to maintain clean premises and equipment, but do not specify a fixed frequency. In practice, most commercial kitchens require a full deep clean every 3 to 6 months, with high-volume operations needing quarterly cleans. Your EHO may specify a frequency during an inspection. We can advise on the appropriate schedule for your operation.
What is included in a commercial kitchen deep clean?
A full deep clean covers all cooking equipment (ovens, fryers, grills, ranges), walls, floors, ceiling voids, refrigeration units, dishwashers, all stainless steel surfaces, and behind and beneath all equipment. We use specialist degreasers and decarbonising agents. A full written cleaning record with photographs is issued on completion.
Is kitchen deep cleaning a legal requirement in Scotland?
Yes. Under the Food Hygiene (Scotland) Regulations 2006, food business operators must keep premises and equipment clean and in good repair. Failure to maintain adequate cleaning standards can result in improvement notices, prohibition orders, and prosecution by your local Environmental Health department.
Will a deep clean improve my food hygiene rating?
A thorough deep clean directly supports a good food hygiene rating. EHOs assess the cleanliness of your premises and equipment as part of every inspection. A documented cleaning programme with written records demonstrates due diligence and supports a higher rating. We provide written records suitable for your EHO on every visit.
Can you work around our opening hours?
Yes. We schedule all deep cleans to minimise disruption to your operation — typically overnight or during your closed period. We carry out a pre-clean survey to plan access, equipment isolation, and timing before every job.
