Duct Work Cleaning: How Often Should Your Kitchen Extracts Be Cleaned?

Is Duct Work Cleaning Every 2 Years Enough?

As a general rule, the minimum requirement for duct work cleaning is every 2 years, but for many businesses a more frequent schedule is vital. As a business owner, you have a duty to ensure that extract cleaning is carried out as often as necessary to keep air quality to acceptable levels. How quickly ducts and filters need cleaning will vary, depending on the type of use and type of occupants. 

The Law
Current legislation states that duct work cleaning must be carried out at least every 2 years for general systems, such as air conditioning for offices. However, there is a more frequent requirement for yearly cleaning of kitchen extracts and duct work. Although "every 2 years" or "every 1 year" is often regarded as the guideline, the law actually says each premises must be assessed on its own requirements. That means you need to call on professional expertise to get the frequency of industrial extraction cleaning right.

Under fire regulations, as well as those covering health and safety at work, the manager of any workplace must take action to eradicate any risks or keep them to a minimum. These rules make it a requirement to check kitchen extract systems in order to find any possible fire dangers, and act to remove them by ensuring any grease build-up is regularly cleared.  

Reasons You Might Need More Frequent Duct Work Cleaning
If you work in an establishment which has high levels of airborne dust or grease, it is likely your duct work will need to be cleaned far more frequently than the legal minimums. This especially applies to kitchens where equipment such as deep fat fryers, grills, wood or charcoal burners is used.

According to expert duct cleaners, in some hamburger restaurants using this kind of equipment, especially those open round the clock, duct work cleaning may be needed as often as monthly. For some other fast food outlets, the suggested frequency is around every two months, while a 90-day regime may be appropriate for most restaurants and works canteens. In some smaller restaurants, six-monthly kitchen extract cleaning is suitable, but you should get expert advice to decide on the optimum schedule for your particular business. 

Other types of business where frequent industrial extraction cleaning is necessary include manufacturing works, such as printworks and those handling paper or textiles. Workplaces close to an external source of pollution, such as motorways, factories or chimneys, are also likely to require duct work cleaning at shorter intervals than the statutory norm. In these types of premises, where there is heavy use, of up to 16 hours a day, the typical cleaning schedule should be every three months. When premises are in use for between 6 and 12 hours, that may come down to six monthly. 

Greater frequency of extract cleaning is also advised in any establishment with vulnerable occupants, such as kitchens serving schools, care homes and hospices. Ingot has carried out air duct cleaning for a care home group in East Anglia for the last five years, and liaises with facility managers at each site in the group to ensure  cleaning is carried out at a convenient time. 

How Can I Tell What Frequency is Right For Me?

If you are unsure over the best schedule, the way forward is to take advice from a professional cleaning company. This will help to protect you under legislation and will also ensure that your duct work will always be kept to an acceptable standard of cleanliness.
