TR19 Ductwork Specification

• It is very important for health and safety reasons that ductwork, extraction and ventilation systems are cleaned properly and effectively. In order to measure this, cleaning standards must be met by the Building Engineering Service Association’s (BESA) TR19 standards. 

​

• The BESA TR19 guidelines are updated and amended regularly, and the changes must be followed closely. Failure to meet all of the TR19 document standards could make you liable in the event of a hazard caused by improperly cleaned ducts. It could also null and void your insurance coverage. 

​

• The TR19 guidelines state that the system must contain enough access panels of sufficient size to enable regular inspection and cleaning.

​

• The access panels should be made of the same material as the ductwork and should include insulation, seals (to prevent leaks) and quick-release catches at every 1.0m installed by a specialist cleaning contractor.

​

• Consequently, if your system is non-compliant with TR/19, your buildings insurance may be compromised. Insurance providers may refuse to pay out in the event of a fire if the cause is a non-compliant extract system, because this can fuel a fire and spread it further.

​

• The person responsible for the non-compliant extract system can also face prosecution for negligence, especially if there has been severe damage, injury, or loss of life as a result of a kitchen extract system fire. If found guilty, the responsible person could potentially be given a custodial sentence.
