Fire, insurance & risk
It's usually not hidden malice - it's a maintenance warranty. Here's how the wording removes your cover, and how to satisfy it before a fire tests it.
The short answer
The clause that sinks most kitchen-fire claims is not hidden malice - it is an ordinary maintenance term written as a warranty. Many policies require the extract system to be cleaned to TR19 at a stated frequency, and a warranty must be met exactly. Break it and the insurer can decline the claim - sometimes even if the breach had nothing to do with the fire. It voids cover quietly because it works on breach, not on blame.
Warranty versus condition
Not all policy terms behave the same way. A general condition usually has to have some bearing on the loss before it bites. A warranty is stricter: it is a promise that something is true or will be done, and it must be complied with precisely. Insurers increasingly write the extract-cleaning requirement as an express warranty - the system will be cleaned to TR19 at a stated interval - because it gives them a clean basis to decline if it is not met.
The trap is that a warranty can be breached without you realising and can affect a claim even where the breach did not cause the fire. If the policy warrants six-monthly TR19 cleaning and your last clean was eight months ago, the warranty is broken on the day of the fire regardless of how the fire started.
The other quiet clauses
Two more terms catch operators out. Most policies carry a reasonable-precautions or reasonable-care condition, requiring you to take sensible steps to prevent foreseeable loss. A grease-laden, un-evidenced extract system is very hard to defend as reasonable once a fire has happened, so this condition hands the insurer a second line of argument.
The quietest of all is the notification or non-disclosure condition. Policies typically require you to tell the insurer about enforcement actions or safety notices. Fail to disclose an improvement or prohibition notice and the insurer can treat the cover as void retroactively - as though it never applied - which can undo a claim that otherwise looked sound. None of these clauses announce themselves; they simply sit in the wording until a claim tests them.
Reading your own policy
The defence is simple and cheap: read the schedule and the conditions before renewal, find the extract-cleaning term, and note whether it is a warranty and what interval it names. Then match your cleaning to that interval - not to habit and not only to TR19's minimum, since the policy can be stricter - and keep dated certificates that prove it. Disclose any enforcement notices promptly.
A single denied claim on a serious kitchen fire can run into hundreds of thousands, even millions, of pounds. Set against that, checking one clause and holding the right certificates is the cheapest insurance you will ever buy.
Questions
Most commonly an express maintenance warranty requiring the extract system to be cleaned to TR19 at a stated frequency. A warranty must be met exactly, so breaching it can let the insurer decline the claim.
A condition usually needs some bearing on the loss to apply. A warranty is a strict promise that must be complied with precisely, and breaking it can affect a claim even if it did not cause the fire.
