Commercial Kitchen Deep Cleaning Standards

How to Keep Your Kitchen Inspection-Ready Through the Busiest Months of the Year

For facilities managers responsible for staff restaurants, hospitality venues or contract catering, the run-up to Christmas is the hardest time to keep a kitchen spotless. Covers increase, menus get busier and equipment runs for longer, all while an Environmental Health Officer (EHO) can visit without notice.

The Food Hygiene Rating your kitchen receives is displayed publicly and can stay in place for months. This guide explains the standards inspectors look for, the risks of falling behind and how to build a deep cleaning routine that keeps you compliant all winter.
 

What EHOs Look For in a Commercial Kitchen

Under the Food Hygiene Rating Scheme, inspectors score three areas. Cleaning affects all of them.

Hygienic Food Handling

Inspectors check how food is prepared, stored and cooked, including cross-contamination controls. Clean, disinfected preparation surfaces, chopping boards and utensils are the foundation of safe handling.

Condition of the Structure

This covers the cleanliness and repair of walls, floors, ceilings, equipment, lighting and ventilation. Grease on canopy exteriors, grime behind cooking lines and dirty floor edges are common reasons for a lower score.

Confidence in Management

Inspectors want evidence that food safety is managed, not left to chance. Written cleaning schedules, completed sign-off sheets and records of deep cleans all show that hygiene is controlled.
 

Four Deep Cleaning Standards to Put in Place Before Winter
 

1. Separate Daily Cleaning From Structural Deep Cleaning

Daily cleaning keeps surfaces safe during service. A structural deep clean goes further, removing built-up grease and carbon from walls, ceilings, behind and under equipment, and canopy exteriors. Most busy kitchens need a full deep clean at least quarterly, with high-use areas cleaned more often.

2. Use Products Tested to Recognised Standards

Disinfectants used on food contact surfaces should be food-safe and tested to BS EN 1276, the standard for bactericidal activity. Follow the stated contact time, and rinse where the label requires. Every product should have a COSHH assessment on file.

3. Clean in the Right Order

Work from top to bottom and from clean areas to dirty ones. High-level surfaces and canopy exteriors come first, followed by equipment, worktops and finally floors and drains. Cleaning in the wrong order simply moves dirt onto surfaces you have already cleaned.

4. Know Where Specialist Work Is Needed

Grease build-up inside extraction ductwork is a serious fire risk and is usually cleaned to the TR19 Grease specification by a specialist contractor. Grease traps also need specialist servicing. Your deep cleaning partner should be clear about what they do and do not cover.
 

Your Pre-Audit Kitchen Checklist

• Is your cleaning schedule written down, covering daily, weekly and periodic tasks?
• Are completed cleaning records signed and dated, and kept on site where an inspector can see them?
• When was your last structural deep clean, and is the next one booked before peak trading?
• Do all disinfectants meet BS EN 1276, with COSHH assessments on file?
• Is your extraction ductwork cleaning certificate in date, completed by a specialist?

Frequently Asked Questions
 

How often should a commercial kitchen be deep cleaned?

Most busy commercial kitchens benefit from a full structural deep clean every three months, with high-use equipment and areas cleaned more often. Kitchens running long hours or high volumes may need monthly deep cleans.

What records should we keep for an EHO inspection?

Keep a written cleaning schedule, completed and signed cleaning logs, deep clean records, COSHH assessments for your chemicals and certificates for specialist work such as ductwork cleaning.

Can a kitchen be deep cleaned without closing?

Yes. Deep cleans can be scheduled overnight or between services, so the kitchen is reset and ready before the next shift.
