As a result of the Fire Risk related to Commercial Kitchen Extraction Systems, most insurance companies require businesses to perform Deep Cleans to their Extraction Systems to ensure the build-up of grease is kept to a minimum. The frequency of the clean is dependent on the type of cooking and the service hours per day but recommended at minimum once a year. 


Failure to meet the hygiene standards set out by the Food and Safety Act 1990 and the food Hygiene Regulations 2006 can lead to large fines. Whilst your staff can perform daily cleaning tasks to keep the cleanliness to a basic level, a regular cleaning program carried out by professionals is essential. Failure to carry out proper cleaning and maintenance could lead to a breach of Environmental Health Regulations and could invalidate your fire insurance policy. 

Under the Regulatory Reform (Fire Safety) Order 2005, your extraction system needs to be included in your fire risk assessment with action taken to minimise any potential fire risks to buildings and occupants. Hygiene levels within your kitchen are totally reliant on the level of cleaning undertaken.

Commercial kitchen extraction cleaning is the process of cleaning the extraction systems in commercial kitchens. The purpose of this cleaning is to remove the build-up of grease and other flammable substances that accumulate in the kitchen's system over time.

The extraction system in a commercial kitchen includes the kitchen hood, which is the visible part of the system located over the cooking equipment, as well as ductwork, fans, and other components that are hidden from view. These components can become clogged with grease and other substances, which can create a fire hazard and reduce the efficiency of the ventilation system.

Commercial kitchen extraction cleaning typically involves the use of specialised equipment and chemicals to clean the kitchen hood and ductwork. The cleaning process usually begins with a thorough inspection of the system to identify areas of build-up and determine the best approach for cleaning.  Kitchen extraction cleaning should be performed on a regular basis to maintain the safety and efficiency of the ventilation system.

In addition to reducing fire hazards and improving ventilation, regular kitchen extraction cleaning can also help extend the lifespan of the ventilation system and improve the air quality in the kitchen. It is typically recommended that commercial kitchens have their extraction systems cleaned at least once a year, depending on the volume and type of cooking being done.

The build-up of grease and fat deposits in commercial kitchens is a serious fire risk and if kitchen extraction cleaning is not carried out regularly your insurance may be invalid.  In fact, it is now a requirement of most insurance companies that all grease extraction ducting is cleaned frequently by an accredited specialist company.

​Using specialist kitchen ductwork cleaning services is also advisable to ensure commercial kitchens are kept clean and free from grease or fat deposits; which promotes healthy public food preparation and ensures food prep areas remain hygienic.

All kitchen grease extraction ductwork that is cleaned by us, is cleaned to a high standard.

Our highly qualified duct cleaning staff are DBS checked and have also been trained to clean ductwork to a TR/19 certification enabling us to work on any job in all areas of cleaning.
