Our Kitchen Extract Cleaning Process
-
01. Initial SurveyWe begin every commercial kitchen extract cleaning service with a survey. We consult with you to build a complete picture of your ventilation, air conditioning and kitchen extraction systems. This includes an inspection of your canopy, ductwork and fans to identify contamination levels and fire risks, as it helps to assess the service scope of what cleaning tasks we need to carry out. All cleaning plans are fully tailored to your premises and we ensure a minimal level of disruption to your everyday kitchen operations. Our fire damper inspection process goes beyond just a quick look – we carry out detailed assessments to catch risks before they cause failure. This process begins with an initial survey of your HVAC and fire safety system, where we look for signs of blockages, dust build-up, corrosion or any other obstructions that affect performance. Each fire damper is carefully assessed to make sure it’s accessible and fully operational.

02. Preparation and ProtectionBefore cleaning begins, we take steps to protect your kitchen environment. All surfaces are covered and sealed to ensure that food preparation areas and equipment aren’t affected. Fans and electrical components are isolated for safety, and we plan all work around your working hours so you can operate as normal. After completing the drop test, we reset the damper so it’s ready for use in an emergency. Our team then provides a detailed fire damper testing report based on our findings. If we discover any damage, corrosion or obstructions, we perform maintenance, including cleaning and the replacement of any faulty fusible links. If necessary, we also provide suggestions for remedial action, including maintenance and repairs.

03. Deep Cleaning of Canopies and FiltersKitchen canopies and filters are hotspots for grease to build up, which is why we give them a thorough clean. All internal and external canopy surfaces are degreased and polished, and can even be replaced if required. Filters are also removed and thoroughly cleaned using specialist degreasing solutions to get rid of any stubborn grease. Deep cleaning also includes drip trays to eliminate odours and prevent grease overflow, leaving your kitchen safer and fresher.
-
04. Ductwork CleaningOur engineers also look at your HVAC systems, carrying out necessary kitchen extract duct cleaning to ensure a better airflow throughout your premises. Mechanical brushes and scrapers remove grease and debris from duct walls, while industrial vacuums capture the loosened material. Every section is cleaned to TR19® standards for complete system hygiene, from canopy to discharge point.
-
05. Fan and Discharge System CleaningWhere possible, kitchen fans are dismantled, degreased and deep cleaned to restore maximum performance. Roof fans and discharge vents are treated to remove grease contamination and eliminate odours from inside and outside the building. Once we’ve completed this final step, the fan is reassembled, tested and airflow efficiency verified to ensure everything operates smoothly.
What is Kitchen Extract Cleaning?
Commercial kitchen extract cleaning involves the deep cleaning of your extraction system – including ducting, fans, canopies and filters. The main purpose of professional cleaning is to remove grease, oil and smoke build-up from the ventilation system, as this can pose a serious fire risk due to carbon deposits.
To stay compliant with kitchen extract cleaning regulations, cleaning must meet TR19® standards, as set by the Building Engineering Services Association (BESA). A clean extract system protects your staff and property but also ensures you meet legal obligations and keep insurance valid.

Not at all. We always plan our kitchen extraction cleaning around your business hours to minimise disruption. If necessary, we can carry out cleaning overnight or during quiet periods so your kitchen can operate as normal and you won’t lose any business.
This depends on your system’s size, layout and level of grease build-up. Most cleans are completed within a few hours, but larger systems with a higher level of dirt may take longer. Before we begin, we’ll always provide a clear timeframe so you know what to expect.
Failing to clean your extraction system increases fire risk, reduces airflow and may invalidate your insurance. You also risk failed inspections, fines or in extreme cases, temporary closure by fire or environmental authorities.
