Question 1

What is TR19 kitchen extraction cleaning?

Accepted Answer

TR19 is the BESA (Building Engineering Services Association) standard for the cleaning of ventilation systems in commercial kitchens. It specifies the frequency and method of cleaning grease ducts, canopies and extraction fans to reduce fire risk and maintain insurance compliance.

Question 2

How often does my commercial kitchen extraction system need cleaning?

Accepted Answer

Under TR19 guidelines, cleaning frequency depends on usage: heavy use (e.g. fast food) requires quarterly cleaning; moderate use (e.g. restaurants) requires 6-monthly cleaning; light use requires annual cleaning. Your insurer may have specific requirements.

Question 3

Is TR19 duct cleaning a legal requirement?

Accepted Answer

While TR19 itself is not a law, commercial kitchen operators are legally required under the Regulatory Reform (Fire Safety) Order 2005 to manage fire risk. Most insurers require TR19-compliant cleaning as a condition of commercial kitchen insurance policies.

Question 5

What is the difference between TR19 and NAADUK21?

Accepted Answer

TR19 (published by BESA) is the long-established standard for ventilation duct cleaning in commercial buildings. NAADUK21 is a newer standard published by the National Air Duct Association specifically focused on kitchen extraction systems. Both are recognised by insurers; some policies may require one or both standards.

Question 6

Will my commercial kitchen insurance be void without TR19 cleaning?

Accepted Answer

Yes — most commercial kitchen insurance policies require evidence of TR19-compliant extraction cleaning. Failure to maintain cleaning schedules can invalidate your insurance in the event of a fire. Always request a TR19 certificate after each clean.

Question 7

How much does kitchen extraction duct cleaning cost in the UK?

Accepted Answer

Kitchen extraction cleaning costs in the UK typically range from £150 to £800+ depending on the size of the system, number of fans, duct length, and access difficulty. Budget contractors start around £150, mid-range between £300–£500, and premium specialists may charge more for complex systems.

Question 8

What should a TR19 clean include?

Accepted Answer

A TR19-compliant clean should include cleaning of the canopy/hood, filters, grease duct, extract fan, and all accessible ductwork. The contractor must provide a post-clean report with before-and-after photographs, grease depth measurements, and a TR19 compliance certificate.
