TR19 explained: what every kitchen owner needs to know about insurance compliance

When was the last time anyone looked inside your kitchen extraction ductwork? If the honest answer is “I don’t know” — you’re not alone, and it’s exactly the kind of gap that costs operators dearly when something goes wrong.

What TR19 actually is

TR19 (now sometimes referred to as the BESA TR/19 Specification) is the industry guideline for the internal cleanliness of ventilation systems. Section 9 covers grease extract ventilation in commercial kitchens specifically — the canopies, ductwork and fan units that pull cooking residue out of your kitchen.

It’s not a law. But it is what insurers, fire safety officers and Environmental Health quote when they ask whether your system has been cleaned recently — and what they’ll point at if a claim is denied or a prosecution proceeds.

Why it matters

Three reasons most operators care:

1. Fire risk. Grease build-up in ductwork is one of the most common causes of catastrophic commercial kitchen fires. Once a fire travels into the duct, it travels fast — and often into building voids you can’t reach.
2. Insurance. Most commercial kitchen insurance policies now reference TR19 directly. If your insurer asks for evidence of recent compliance and you can’t provide it, that’s a problem you only discover after a claim.
3. EHO scrutiny. Environmental Health inspections increasingly cover air quality and contamination risk in the food prep environment.

What a proper TR19 clean looks like

It’s not a wipe-down of the visible canopy. Done properly, it involves:

• A pre-clean inspection with photos showing the starting condition
• Access panel installation where ductwork can’t be reached otherwise
• Mechanical and manual cleaning of canopy, ductwork, and fan internals
• Post-clean inspection with photos and a signed compliance certificate
• A copy of that documentation that goes to you for your insurer

If you’re not getting that paperwork at the end, you’re not getting a TR19 clean — you’re getting a wipe-down.

How often?

It depends on use: heavy use (24/7 operations, frying-heavy kitchens) needs quarterly; light use (low-volume catering) might only need annually. We’ll assess your system and recommend a schedule that meets the spec.
