TR19® is the recognised industry standard for ductwork cleaning, created by BESA (the Building Engineering Services Association). It sets out how ventilation systems should be cleaned and maintained to ensure safety, compliance, and hygiene. The TR19® guidelines are widely endorsed by the building engineering community and British insurers, making them the definitive benchmark for both air duct and kitchen grease extract cleaning. All hygiene operatives are expected to follow TR19® as the standard. In addition to promoting cleaner, safer environments, adhering to TR19 standards can also have financial benefits. Insurance providers often require compliance with TR19 for coverage, and failure to meet these standards could result in costly penalties or even the denial of claims. By investing in regular cleaning and maintenance, you not only protect your property and occupants but also safeguard your bottom line.
