TR19 kitchen extract cleaning to the BESA grease specification
The TR19 grease specification is what your insurer references when they ask for "kitchen extract cleaning to standard." We deliver to it, with the certificate to prove it.
TR19 is the Building Engineering Services Association (BESA) specification for internal cleanliness of ventilation systems. For commercial kitchens, the grease section is what insurers reference in policy wording. A TR19 clean covers the full system — not just the canopy — and produces a defensible certificate.

What does TR19 actually require? +
TR19 (current edition: TR19 Grease, 2019) requires the entire extract system to be cleaned to a defined grease level (below 200μm WFT), with documentary evidence and a certificate produced after each clean. Frequency is set by usage hours.
Is TR19 a legal requirement? +
TR19 itself is a technical specification, not a statute. But the Regulatory Reform (Fire Safety) Order 2005 places a legal duty on the responsible person to manage fire risk — and TR19 is the recognised industry standard for evidencing that the extract system is not a fire risk.
Will my insurance pay out without a TR19 certificate? +
It depends on the policy wording. Most commercial kitchen insurance policies now reference TR19 (or the BESA grease specification) directly. Without a current certificate, claims for kitchen fire damage are routinely refused or reduced.
How long does a TR19 clean take? +
A typical independent restaurant: one overnight (8–10 hours). A large hotel or multi-canopy site: 2–4 nights. We confirm timing at survey.
Who issues the TR19 certificate? +
We do. Our certificates reference the TR19 Grease standard, include WFT readings at every access point, dated photo evidence and a system schematic. Available digitally within 48 hours.
