Kitchen Extract Cleaning
Fire safety and cleanliness should be a focus of any respectable commercial kitchen. When your kitchen is the heart of your business, can you afford not to look after it?
If regular cleaning of the kitchen extract system is not undertaken then fats, oily deposits and fibrous particles can accumulate, reducing the efficiency and can facilitate the preferred environment for microbiological growth and pests to breed.
Whether you’re a restaurant, hotel or any other type of catering facility, MyDuctwork cleaning services can be tailored to meet your requirements at regular intervals, from weekly to annually. Our professional cleaning operatives will attend your site to carry-out the clean and our friendly team will contact you to let you know when your next clean is due so that we can take the worry from you. This will also ensure that you meet your fire safety obligations under the Regulatory Reform (Fire Safety) Order 2005, minimising the fire risk by removing flammable deposits within your extract system.
Fully Insured & Guaranteed
We are fully insured and all of our works comply with B&ES (Second Edition) Guide to Good Practice TR19 (2013) standards. The clean is verified with a full report with before and after photographs and Wet Film Thickness Test measurements of grease levels.

Considerations for Kitchen Extract Systems
Kitchen Extract (Exhaust) Systems are particularly affected by the deposit of grease and oil onto the internal surfaces from the canopy to the ductwork and all the way through to the fan and discharge, since no filter can be 100% effective. Varying types of cooking and cooking frequency will affect the rate of fouling. Also, other (non-catering) industrial cooking processes can result in contamination of the system such as dust particles, tissue and cloths which can be hidden inside ventilation system.
The Regulatory Reform (Fire Safety) Order places a duty of care on the building owner/occupier to take such general fire precautions as will ensure, so far as reasonably practical the safety of the building and safety of the people within it.
Section 17 of this Order deals with maintenance of systems to control the fire risk and that they are subject to a suitable system of maintenance and are maintained in an efficient state, in efficient working order and in good repair.
By removing the combustion load fire safety is greatly enhanced. This is why the insurers’ Loss Prevention Council recommends regular cleaning by specialists.
Accumulated grease also provides a hygiene hazard and can lead to foul odour, pest infestation and in some cases unhygienic ‘backwash’ of air into the cooking area. Leakage of oil from damaged or poorly-installed ductwork can spread these hazards to building areas such as ceiling voids and service shafts.
Why Clean and maintain?
In short is it your responsibility to ensure the safety of people, property and economy. By regularly cleaning and maintaining your kitchen ventilation system you will:
- Reduce the risk of fire.
- Prevents the build-up of grease deposits, bacteria of pests within your kitchen. extraction system.
- Ensure that you comply with Legislation and Guidance.
- Insurance policies will often stipulate clauses relating to proper preventative maintenance and failure to properly maintain systems may cause claims to be affected.
How often should I clean?
The frequency of cleaning should be sufficiently frequent that grease deposit limits are not exceeded. In the absence of data on measured levels of cleanliness, time-and-usage-based methods are often used to estimate required cleaning frequency (see table below). Pre-cleaning micron readings should be taken to enable cleaning frequency to be confirmed as suitable or adjusted accordingly.

Did you know?
- 70 percent of fires in commercial kitchens originate in faulty extract ventilation systems due to buildup of fat and grease.
- Grease build up also causes an environmental health hazard by providing a breeding ground for bacteria and pests.
- You can reduce these risks by carrying out regular cleaning of your kitchen extraction and ventilation systems.
Legislation & Guidance
Legislation and guidance on standards in buildings is largely oriented towards the design and construction of buildings and associated systems. Increasingly the proper maintenance of building systems is recognised as crucial to the healthy, economic and safe operation of occupied spaces.
Relevant legislation includes but is not restricted to the following:
- The Regulatory Reform (Fire Safety) Order 2005
- BS9999: 2017 Code of Practice for Fire Safety in the Design, Management and Use of Buildings.
- Health and Safety at Work Act 1974
