Clean, well-maintained kitchen ventilation systems are critical for fire prevention, air quality, and operational efficiency. B&ES TR/19 (Building Engineering Services Association Technical Bulletin 19) provides the industry’s recognised standard for the internal cleanliness of ventilation systems, including grease extract ductwork.
At Marlowe Environmental Services, we help organisations implement and maintain compliance with TR/19. Our experienced air hygiene specialists deliver inspection, cleaning, and verification services aligned with the standard, ensuring systems meet both insurer expectations and regulatory requirements.
B&ES TR/19 sets out the best-practice guidance for maintaining the cleanliness and integrity of ventilation and kitchen extract systems. The document defines cleaning frequencies, methods, and record-keeping standards that help reduce fire risks and improve indoor air quality.
Many insurers now require that ductwork cleaning is carried out in accordance with TR/19, and that only accredited contractors capable of meeting its requirements are appointed.

Compliance with TR/19 demonstrates a proactive commitment to safety, compliance, and operational reliability, ensuring systems perform safely and efficiently every day.
TR/19 is the industry’s recognised guidance document for the internal cleanliness of ventilation systems. It sets standards for inspection, cleaning, and reporting to ensure safety, fire prevention, and air quality.
TR/19 applies to any organisation operating kitchen extract systems or mechanical ventilation, including restaurants, hospitals, schools, hotels, and commercial buildings.
Grease accumulation in kitchen extract ductwork can pose a severe fire risk. TR/19 outlines how to control this hazard through regular cleaning and verification.
We provide comprehensive ductwork cleaning, verification, and documentation services aligned with TR/19 standards, ensuring compliance with insurers and health and safety regulations.
While TR/19 itself is not legislation, compliance supports legal obligations under the Health and Safety at Work Act 1974, Regulatory Reform (Fire Safety) Order 2005, and COSHH Regulations.
