Duct Cleaning for Specialist Business Sectors

Kitchen extract systems naturally accumulate grease, fat and oil deposits over time. Even in the cleanest commercial kitchens, these deposits create a significant fire risk and must be removed through regular cleaning in accordance with TR19 guidance.

Businesses operating commercial kitchens have a legal duty to manage fire risks and maintain safe extraction systems. Regular kitchen extract cleaning also helps satisfy insurance requirements, supports fire risk assessments and demonstrates compliance with current fire safety legislation.

The frequency of cleaning depends on how heavily your kitchen is used. Our experienced engineers can assess your kitchen extract system, recommend an appropriate cleaning schedule and provide full photographic reports and compliance certificates following every clean.

Your ventilation ductwork must also be cleaned regularly to comply with TR/19. This stipulates that ventilation ductwork must be classified as high, medium or low. This is dictated by how you use the spaces within your property. The ductwork which serves front of house may need a different classification to the maintenance areas behind the scenes

These ratings will determine how often the ductwork must be tested or cleaned, so it needs to be correct. If you aren’t sure, we can classify each part of the system for you and help to devise a plan to bring your ductwork up to a compliant condition. Then we can help you to establish and ongoing schedule to ensure that you meet your legal obligation and stay compliant for the future.

Another very important passive fire prevention measure is the regular testing, cleaning and maintenance of fire dampers. These are metal louvres which can open and close and are installed across the ductwork to form a temporary barrier when closed but allow the free flow of air when open. You may not even be aware that your ventilation system has fire dampers, but they fulfil a very important function, so you must be sure that they are in working order.

In the event of a fire travelling through ductwork, the fire damper must close, to restrict the oxygen supply to the fire and create a barrier which slows the spread of the fire. This buys valuable time in which to safely evacuate shoppers, especially the more vulnerable and less mobile centre visitors.

There are different types of fire damper; some are spring operated, some have fusible links and there are other designs which are remotely operated. All types must be regularly tested, using a method known as drop testing, cleaned and maintained. According to recently updated guidance, BS9999:2017, all fire dampers must now be tested at no more than twelve month intervals.

We can help you locate your fire dampers, create access to inaccessible fire dampers then drop test, clean and maintain them for compliance. More information can be found on our fire dampers page.

Maintaining clean ventilation systems is about more than compliance. Poorly maintained ductwork can affect indoor air quality, reduce ventilation efficiency and contribute to the spread of dust, debris and airborne contaminants throughout a building.

Our ventilation hygiene services include detailed inspections, system cleaning and comprehensive reporting to help businesses maintain safe, hygienic and efficient ventilation systems.

Every project is completed with photographic evidence and supporting documentation to demonstrate the work carried out.

Whether you manage a warehouse, hotel, office, leisure facility or manufacturing site, we can tailor a ventilation hygiene programme to suit your building and requirements.
