What Are My Kitchen Extraction Obligations?

Due to the huge fire, a build-up risk hot grease poses to a building's fire security, regular kitchen extraction cleaning is normally a stipulated requirement of building insurance.

Regular ductwork cleaning cycles should be completed to the BESA TR19 Grease standard by a certified, accredited company.

Compliance In Three Easy Steps


Kitchen ductwork can vary from simple systems through an outside wall to large, complex systems discharging a long way from the extraction canopy. A compliant kitchen duct clean should include the whole system (and all components) so an initial survey to trace the system and the level of contamination before ductwork cleaning is usually recommended.


Kitchen extraction cleaning involves manually removing the grease or carbon from the duct, in most cases by installing access doors into the duct to reach inside to clean the system. All components should be cleaning including the kitchen canopy, filters, fan, and discharge.


Cleaning intervals should be based on the individual usage of the kitchen ductwork. Kitchen exact cleaning should take place when the ductwork reaches an average deposit level of 200μm (micron), gathering this data on each clean allows us to predict the future cleaning frequencies allowing extract cleaning to take place before it becomes a fire hazard.

A word from our CEO

"Kitchen extraction cleaning - the job nobody wants to do "

"Kitchen extraction system cleaning has been neglected for many years by restaurant owners as a job hidden from sight, not contributing to the profitability of the business. Over the past 10 years or so (and due to the sheer volume of kitchen extract fires costing insurers over £65million per year) thankfully insurers now recognise the difference between compliant accredited cleaning and poor standards. It is standard now for insurers to insist on BESA TR19 Grease-compliant certification to protect the restaurants.

The emphasis on compliant workmanship has driven a massive change in the industry which now has accredited training courses in the shape of the GHT courses for extraction cleaning engineers and the formation of the Vent Hygiene Elite scheme in 2019 allowing quality extraction cleaning companies to demonstrate their competence to clients." - Titus W. (CEO)
