Air Ventilation and Ductwork Cleaning

Dirty ventilation ductwork moves contaminated air through your building and drives down indoor air quality. Our technicians survey, clean and verify supply and extract systems to BESA TR19, the recognised standard for ventilation hygiene. Clean Ducts is a BESCA Vent Hygiene Associate member, and our cleaning technicians are trained by BESA.

Why routine ductwork cleaning is necessary

Poor indoor air quality affects the health and wellbeing of everyone in a building, and dirty ventilation systems are a direct cause. In the UK, providing a safe and healthy working environment — including clean indoor air — is a legal duty for employers under the Health and Safety at Work etc. Act 1974 and the Occupiers’ Liability Act 1984.

Those duties require ductwork to be cleaned regularly and kept under a suitable system of maintenance. This applies across commercial buildings, including workplaces, accommodation and public facilities.

BESA TR19 is the leading guidance on ventilation hygiene and sets the benchmark for the internal cleanliness of ductwork. Insurers also expect ventilation systems to be cleaned on a regular basis in line with TR19, and letting this slip can compromise your cover.

How our air ventilation cleaning works

We combine four methods to reach and clear the inside of the system:

• Camera inspection to record the starting condition and locate build-up
• Rotary brushing to break deposits off the duct walls
• Air moving to carry loosened debris to collection points
• Compressed-air jetting to clear what brushing leaves behind

Ventilation systems are cleaned to BESA TR19. Kitchen extract ductwork is cleaned to TR19 Grease, the standard that applies to grease-bearing extract systems.

Proof of quality and compliance

After the clean you receive a detailed report with before-and-after photographs of the ductwork, plus a certificate recording your compliance with the relevant British Standards, health and safety duties and BESA TR19. That gives you documented evidence for your health and safety records, and we handle the paperwork.

To find out where your ventilation system stands, request a survey and we will report on its condition and the cleaning it needs.
