Underwriters price commercial cleaning insurance on risk, and few risks worry them more than kitchen fires and public liability from food-borne illness. A documented cleaning programme demonstrably reduces both, and that shows up in your premium at renewal. The gap between two otherwise identical London restaurants can be several thousand pounds a year at renewal, and it is almost entirely down to paperwork. This guide shows what underwriters care about and how to build a folder that pays for itself.
Quick answer
Commercial cleaning insurance premiums fall when you can prove a documented, contractor-supported cleaning regime. TR19 duct certificates, gas safety records, EHO scores and pest control reports are the four pieces of paper insurers value most. Present them before you are asked; brokers negotiate better quotes when the evidence lands with the enquiry.
What underwriters look at
Restaurant, cafe and pub policies are assessed on:
- Food hygiene rating (FHRS).
- Fire risk assessment and last review date.
- Extraction duct clean records to TR19 standard.
- Gas Safe cooker certification.
- Portable appliance testing dates.
- Claims history over five years.
- Whether cleaning is in-house, contracted or hybrid.
Two identical restaurants will pay very different premiums if one has a compliance folder and the other does not. In our experience the annual difference for a mid-sized London site is often 15-30 per cent of the total premium.

Fire and TR19: the biggest lever
Kitchen fires are catastrophic for hospitality businesses, and grease-lined ducts are their most common ignition source. Insurers now often require TR19 Grease certification and refuse to pay claims where duct cleaning was overdue.
A documented TR19 clean:
- Reduces the physical fire risk.
- Demonstrates due care to the underwriter.
- Provides evidence to protect a claim if a fire does occur.
- Often triggers a discount on property and business-interruption cover.
- Supports the Fire Safety Order duties of the responsible person.
Ask your broker whether your policy has a duct-cleaning warranty; many do, and non-compliance voids fire cover completely.

Public liability and food safety
Public liability policies cover claims from customers, and food poisoning claims are notoriously expensive. A single documented outbreak can cost six figures once medical bills, loss of business and reputational management are added. A documented cleaning schedule, HACCP plan and pest control regime all support your defence if a claim is made.
Key documents to keep:
- Daily temperature logs.
- Signed cleaning schedules for 12+ months.
- Pest control reports for 24+ months.
- Staff training certificates (Level 2 minimum).
- Allergen matrix updates.
- Water quality checks if applicable.
Employers’ liability and slips
Slips and trips are the most common employers’ liability claim in hospitality. Cleaning is central to defending them: mop residue, spilled grease near the fryer, and missing floor drainage all lead to slips.
Simple wins:
- Two-bucket mop system and clean water at every mop.
- Wet floor signs whenever mopping.
- Non-slip footwear as a written condition of employment.
- Fryer splash mats replaced when worn.
- Floor sealed and coved between wall and floor.

Property and business-interruption cover
Beyond public liability, a kitchen fire triggers both property and business-interruption claims. Insurers now often ask about the sum insured for a temporary kitchen or “kitchen in a container” while yours is rebuilt. Documented cleaning is a key factor in the sum insured and rebuild time; without records, expect exclusions or higher excesses.
How to present your programme at renewal
Do not wait for the broker to ask. When you request a quote:
- Attach your latest TR19 certificate.
- Attach your last three EHO scores.
- Attach your gas safety and PAT certificates.
- Provide a copy of the cleaning schedule and pest control contract.
- Note your annual staff training refresh cycle.
Underwriters price certainty. If they can see your systems, they price for a lower risk than the same business without paperwork.
Where a contractor fits
The heaviest tasks (duct cleaning, canopy deep cleans, oven strip-downs, floor and wall deep cleans) are best sub-contracted for two reasons: quality and paperwork. A contractor issues formal certificates that go straight into your insurance file. Ask for the contractor’s own public liability certificate and BESA/BEA (British Extractor Association) accreditation for canopy work.
Ask your broker these questions
- Does my property section have a duct-cleaning warranty?
- What is the sum insured for temporary premises after a fire?
- Is business-interruption cover activated by a partial closure or only full?
- Do you offer a premium discount for TR19 and Gas Safe certificates on file?
Conclusion
Cleaning is an insurance tool as much as a hygiene tool. Our commercial kitchen cleaning service issues certificates for every visit so you can walk into any renewal meeting with evidence in hand. See our coverage to check availability across London.
