If you’re responsible for premises with a kitchen, you’re also responsible for the proper management of the equipment – including the kitchen ducting. Kitchen duct cleaning might seem like a time-consuming chore that you can dismiss with little consequences but failing to make sure they are adequately cleaned at appropriate intervals could mean you’re not complying with regulations. But don’t worry we have all the information and tips you need.
Why do you need to clean a kitchen duct?
When people are busy cooking away the kitchen ducting and extraction system works to remove all the grease, heat, and steam that it creates. The filters built into the system are designed to protect against grease deposits building up but small particles do get through and can accumulate over time.
When left uncleaned, kitchen ducts can become significant fire risks, violating the regulations you should be adhering to. All your extraction ductwork would need to meet TR19 regulations, which specify there should be no grease along any part of the duct that exceeds a thickness of 500um, as any more than this could result in a fire. Your legally obliged to clean ducts under both the Regulatory Reform Order 2005 and the Management of Health and Safety at Work Regulations. You needed to regularly assess for fire risks due to these regulations and checking the kitchen ducts is a core part of this.
