Can Poor Extract Cleaning Affect Your Commercial Kitchen Insurance?

Commercial kitchen fires are among the most common and costly claims faced by food businesses in the UK. What many operators do not realise is that the outcome of an insurance claim following a kitchen fire may depend — at least in part — on whether their extract system was adequately maintained and properly documented. Here is what every food business owner needs to understand.

The Insurance Industry's Position on Extract Cleaning

Commercial property and business interruption insurance policies are contracts. Like all contracts, they come with conditions. Many policies for food businesses include requirements relating to kitchen maintenance and specifically to extract system cleaning.

These requirements vary between insurers and policy types, but common formulations include:

• —A requirement that kitchen extract systems are cleaned by a competent contractor at intervals that reflect the intensity of kitchen use
• —A specific reference to TR19 guidance on cleaning frequencies and documentation
• —A requirement to maintain records of all extract system cleaning and maintenance

Where these conditions exist in your policy and are not met, your insurer may have grounds to reduce or decline a claim related to a kitchen fire.

What Happens After a Commercial Kitchen Fire?

When a fire claim is made, insurers typically conduct an investigation. For kitchen fires, this investigation will almost always look at the state of the extract system at the time of the fire. Loss adjusters are experienced in identifying whether grease accumulation in ductwork or at the canopy contributed to the fire or its spread.

If the investigation finds that the extract system was poorly maintained — and particularly if this can be connected to the cause or spread of the fire — the insurer will review whether the policy conditions relating to maintenance were met. If they were not, this may affect the outcome of the claim.

This does not automatically mean a claim will be declined, but it creates a serious risk of complications, reductions or full denial at precisely the moment your business most needs its insurance to perform.

The Documentation Problem

Beyond the physical state of the extract system, documentation is critical. Even if your kitchen extract system has been cleaned, if you cannot demonstrate this with appropriate records, you may struggle to counter an insurer's assertion that maintenance was inadequate.

Appropriate documentation includes:

Post-clean certificates confirming the date, scope and method of the clean, the contractor who carried it out and the recommended next service interval.

Grease level assessments where applicable, showing the condition of ductwork before and after cleaning.

A maintenance log showing the cleaning history of the system, ideally going back several years.

Without these records, even a well-maintained kitchen faces a significantly harder path through an insurance investigation.

What To Do If Your Policy Is Up for Renewal

Insurance renewal is an important moment to review your extract system maintenance position. Here is what we recommend:

Review your policy documents — Check whether your current policy includes specific requirements about extract cleaning frequency, standards or documentation. If the wording is unclear, ask your broker.

Get documentation in order — If you have had professional cleaning carried out but cannot locate the post-clean reports, contact the contractor and request copies. If records cannot be retrieved, arrange a new professional clean and ensure proper documentation is produced this time.

Check your cleaning schedule — Review whether your current cleaning frequency is appropriate for your kitchen's use intensity. If you have been having annual cleans but operate a high-volume fryer kitchen, your schedule may not align with TR19 guidance — and may not satisfy your insurer's requirements.

Discuss with your broker — When renewing, specifically raise the question of extract cleaning requirements with your broker. Ask them to confirm exactly what evidence your insurer would require in the event of a claim.

The Insurance Broker Perspective

Most commercial insurance brokers serving the hospitality and food service sector are well aware of the extract cleaning issue. Many will proactively raise it at renewal. However, it is always worth initiating the conversation yourself rather than assuming everything is covered.

Some brokers can arrange specific kitchen extract cleaning requirements inspections or audits as part of the renewal process, particularly for higher-value restaurant or hotel policies.

For New or Changing Policies

If you are taking out a new commercial policy, arranging additional kitchen covers, or switching insurers, it is worth specifically asking about extract cleaning requirements before you commit. Some policies are more demanding than others. Understanding what documentation your new insurer requires allows you to ensure your maintenance programme delivers it.

Protecting Your Business

The practical steps for protecting your business are straightforward:

1. Establish a compliant cleaning schedule aligned to TR19 guidance for your kitchen type 2. Use competent contractors who produce post-clean documentation 3. Keep all post-clean records securely filed alongside your fire risk assessment and insurance documents 4. Review your schedule when your kitchen operations change — new equipment, extended hours or increased output may require more frequent cleaning 5. Check your policy at renewal to confirm the documentation your insurer requires
