The Paragraph That Voids Your Kitchen Insurance

Most commercial kitchen insurance policies contain maintenance conditions — often written as conditions precedent — that make cover depend on specific work being done, on schedule, with dated evidence. The big one is extraction duct cleaning to the BESA TR19 Grease specification at intervals set by usage. TR19 is an industry specification, not legislation, but it is the standard insurers reference. Miss the interval or lose the certificate and a fire claim can be disputed in whole or in part — even when the fire started elsewhere and merely spread through the ductwork.

Picture a takeaway on a Friday night. A pan flares, the flame is drawn into the canopy and travels the duct, and the kitchen is out for months. There is buildings cover, contents, business interruption — and the loss adjuster’s first substantive question is not about the pan. It is: when was the extraction last cleaned, to what standard, and can you show me the certificate? That is not one incident; it is the shape of a kitchen fire claim. One claims-practice explainer on TR19 and kitchen fire claims puts it plainly: cleaning that is overdue, undocumented or not to TR19 standards gives the insurer grounds to dispute the claim — outright rejection included. What makes that possible is a single paragraph in your policy wording; this article is about finding it before an adjuster does.

What a condition precedent is — and why the label decides claims

Operators read a policy as a list of what is covered; insurers also write it as a list of things you must do. A condition precedent makes the insurer’s liability conditional on your compliance: if fire cover is subject to the extraction system being professionally cleaned at stated intervals with records kept, failing to comply can entitle the insurer to decline the claim. A mere condition is weaker — the insurer generally has to show the breach actually caused or worsened the loss. Same behaviour, same fire, very different outcome, decided by the label on the clause.

The Insurance Act 2015 softened the sharpest edges: an insurer cannot rely on a breach that could not have increased the risk of the loss that actually happened. That helps the café whose duct paperwork lapsed before a burst pipe flooded the cellar; it does not help the operator whose grease-laden duct carried a fire. Which label your terms carry is broker question one.

The kitchen clauses to hunt for

Three families of clause recur in hospitality policies, living in the schedule, endorsements and policy conditions — rarely in the glossy summary.

1. Extraction cleaning to TR19 Grease

TR19 Grease — in full, Fire Risk Management of Grease Accumulation within Kitchen Extraction Systems — is a specification published by the Building Engineering Services Association (BESA). It is not legislation: the legal duty to manage fire risk comes from fire-safety law, and TR19 Grease is the industry’s answer to how. BESA’s own guidance notes that many policies now explicitly require adherence to TR19 standards and that a lapsed cleaning regime can invalidate commercial cover; AXA’s guidance to its brokers warns the same from the insurer’s side.

Those intervals are minimums keyed to daily cooking hours; the real frequency comes from a competent person’s risk assessment, and the benchmark is physical — mean grease deposits below 200 microns between cleans. Certification runs through BESCA’s Vent Hygiene Elite scheme, with technicians holding BESA’s Grease Hygiene Technician qualification. If your policy names TR19, a mate with a pressure washer does not discharge the condition — nor does cleaning canopy and filters while the duct runs untouched — the specification covers the complete system.

2. Frying-equipment warranties and conditions

Deep-fat frying is the activity underwriters worry about most, so policies for fryer-led businesses often carry specific terms: working high-limit thermostats, minimum clearances, fire blanket or suppression provision, sometimes fryer servicing requirements. The logic is the same as ducting — the clause is only satisfied by the thing actually working, and the burden of showing it lands on you after the event. A thermostat bypassed or failed unrepaired is precisely the paragraph an adjuster will find. (Manufacturer warranties carry their own small print — a different instrument from your policy.)

3. Alarm, close-down and unattended-cooking conditions

The third family covers procedure: alarms maintained and set, cooking never left unattended, a nightly close-down routine. Written as obligations, they fail quietly: the alarm contract lapses, the closing checklist stops being initialled, and nothing happens — until the night something does.

The evidence habit

The pattern across all three: after a loss, the question is never only “did you do it?” but “can you show it?”. An adjuster will ask for dated cleaning certificates, post-clean reports with photographs and measurements, proof that flagged problems were fixed, and the records behind the other conditions. An honest verbal account is worth very little against a policy that demanded documents.

The fix costs almost nothing. Keep one folder — digital and physical, a copy off site — holding every TR19 certificate and post-clean report, every service sheet, the alarm contract and the closing checklists. Diarise the next duct clean the day the certificate arrives. If the cleaner’s report says a duct section could not be accessed, treat that as a live problem: an inaccessible section is an uncleaned section, and it will be visible in the wreckage even if it was invisible in the ceiling. It is the fridge-temperature discipline of The EHO Fridge Evidence Pack, pointed at a different inspector.

Read your policy tonight: three questions for your broker

The paragraph this article is named after will not be in the marketing summary. Get the full wording, the schedule and every endorsement — that is where kitchen conditions usually attach, and an endorsement can add a condition precedent the base wording never mentions. Search for “condition precedent”, “warranty”, “TR19”, “extraction”, “duct”, “frying” and “unattended”, read what each clause requires, then compare it with your diary and folder.

Then make the call — not to ask whether you are covered, but to have your wording translated into a maintenance calendar.

• 1
  Which requirements are conditions precedent or warranties? Ask for them listed clause by clause, with the standard, interval and evidence each demands.
• 2
  What would the insurer expect to see after a fire? Put your folder next to that list. Gaps found tonight are diary entries; gaps found by a loss adjuster are grounds.
• 3
  What changes must we notify? Longer hours push you up TR19’s usage bands; a new fryer or chargrill-heavy menu alters the risk the policy was priced on. Ask what triggers a notification duty.

Where equipment choices touch this

One paragraph, because this is a maintenance story: equipment choices set how easy the conditions are to live with. Extraction designed with access panels gets cleaned to the full TR19 scope; ductwork nobody can reach breeds the “not accessed” lines that haunt post-clean reports — our extraction and fire-safety cleaning schedules guide covers building the regime itself. Fryers with serviceable thermostats and cut-outs keep clause type 2 satisfied without workarounds; the commercial fryer buying guide treats those safety features as specification items, not extras. The same habit protects the refrigeration side, where failure arrives through stock rather than flame — see what a fridge breakdown really costs.
