TR19 Cleaning


Our team carry out TR19 Standard kitchen extraction cleaning to ensure safety within your establishment.

The TR19 is a standard that BESA defines to standardise duct and extraction cleaning systems.

Developed in 1988, BESA is the standard the majority of insurers and building engineering service sectors use when performing kitchen extract system cleaning.

To find out more about how often ductwork and kitchen extract systems must be kept clean, please contact our team using the enquiry form provided.

What is BESA?

BESA is the Building Engineering Services Association.

Founded in 1904, BESA was previously known as the Heating and Ventilating Contractors’ Association (HVCA) TR19.

They defined the TR19 standards for performing duct cleaning 20 years ago, which has today become the go-to standard.

Insurance companies only provide insurance to companies if they have a certificate of duct cleanliness that specifies that their ducts have been cleaned as per this standard.

For more information on internal cleanliness and BESA certified cleaning make sure to contact our team today.

Keeping your Workplace TR19 Ready

The TR19 standard isn’t just about meeting guidelines. It also keeps the air we breathe cleaner.

Properly cleaned ductwork can make employees healthier, happier, and more productive. Our site surveyors thoroughly check your exterior and interior ductwork and kitchen ventilation systems.

With regular checks, you can be safe, knowing that your work environment will always be TR19 ready.

Ferncroft can help you keep on top of your systems and filters at any time or regularly. To find out the costs for cleaning ductwork systems, please get in touch with us today.

Cleaning for TR19

Our deep cleaning processes remove all contaminants from duct and ventilation systems. If your duct system has difficult access for a complete clean, we can easily install access points.

If microbiological problems are present, we can disinfect and deal with that too. We have the necessary extract cleaning tools that allow us to clean to the TR19 standard.

We can easily remove contaminants at minimal disruption to the duct system. If you have a system that’s hard to access, we are prepared to make your system easier to clean now and for future cleaning requirements.

Understanding TR19 Ductwork Specifications

VHL follows the Building Engineering Service Association’s (BESA) TR19 guidelines closely. If you don’t meet all of the TR19 document standards, this could mean the ducts are not cleaned properly, making you liable in the event of a hazard.

VHL’s staff are always up-to-date with the latest TR19 protocols, and cleaning kitchen extraction systems is always according to TR19 rules.

You can relax in the knowledge that our ductwork surfaces cleaning processes, canopy fan cleaning processes, and cleaning process of kitchen extractions systems are all the same as the British Standard and European Norm BSEN:15780 and the Building Services Research and Information Association’s BG49/2013 on commissioning air systems.

After carrying out our fan cleaning processes, we can carry out post cleaning verification methods to ensure safety and high quality. Contact us today for more information on our services.

Is My Service Provider TR19 Compliant?

BESA has strict criteria that must be met by a service provider to be TR19 compliant. This ensures that companies provide a high enough standard of cleaning to help reduce the risk of kitchen fires.

There should be post cleaning verification methods performed after the ventilation system has been cleaned and a deposit thickness test has been completed.

Check out the criteria to determine whether your current service provider has the necessary training necessary to meet BESA requirements for TR19 compliance.

If you do not have the training required to meet the criteria, it is not a TR19 compliant service.

Why are the TR19 Guidelines Important?

TR19 is a recognised standard that involves measuring grease levels and identifying recommended cleaning frequencies. It is designed to reduce the risk of fire and is tailored to your system.

Regularly cleaning grease deposits can promote a good working environment. It takes away heat from cooking to maintain a good airflow supply and reduce fire risk, making it essential when considering fire risk management.

If a fire occurs due to inadequate cleaning methods of ductwork, then it could jeopardise your right to indemnity for loss or damage, says BESA.

How Can We Help You Be TR19 Compliant?

Our experts have access to specialised remote brushing equipment to ensure that we can clean your ductwork system to its entirety. In addition, a report with photographs and measurements is provided as part of our monitoring and inspection service.

A comprehensive TR19 compliant report with recommendations post clean photographs and measurements and a suggested cleaning frequency using BESA’s accumulation assessment table.

We can offer more information on TR19 compliant services if required.

Legislation & Regulations for Ductwork Cleaning

Building and surrounding public buildings will have ductwork in many shapes and sizes. Much of it is hidden from view, but not all can be seen and can cause a build-up in it.

Clean ductwork guidelines have been issued in B&ES TR19, BS EN15780 to protect the health and wellbeing of people who inhale air that flows over the ductwork, which can lead to dust and debris build up over a long period, causing a health and wellbeing risk to all who breathe the air.

Kitchen Extract Cleaning B&ES Association TR19 'Guide to Good Practice'

All ductwork and ventilation must be classified as a level. These levels are low, medium or high, which signify the purpose and function of that part of the property.

We carry out vent hygiene cleaning in line with the rules and regulations set out by the TR19 standard. Here are the recommended cleaning cycles for commercial kitchen extraction systems.

How much does TR19 cost?

The cost for a TR19 can vary. If the ductwork at your establishment has not been cleaned before, it is likely to take more time and effort. Other factors such as ductwork length, ease of access and cleaning methods can also affect the price.

As you may expect with any service, you will get what you pay for. If a budget provider is chosen, there will be no guarantee the work meets the official TR19 standard. This can leave your business at serious risk should anything go wrong.

Most importantly, when looking at cost, make sure you know exactly what is being provided within the service. So make sure to get the information on what you are being provided in the service.

How often should Duct Cleaning be completed?

Busy commercial kitchens often require TR19 cleaning every three months, while less busy establishments require it every six months.

Different kitchens operate at different intensities, so they don’t need the same amount of maintenance.

Generally, the busier the kitchen, the more often performing ductwork cleaning operations and extraction systems should be cleaned. Busier kitchens require a tr19 cleaning every six months and once a year for cleaning ductwork systems.

What are the Risks of Non-Compliance?

Failure to adhere to TR19 standards can have serious consequences. For example, there is a risk of a serious fire occurring.

This is because cooking in commercial kitchens creates flammable by-products. They are extracted by the ventilation system and stick to the inside of the ductwork.

If these are not removed, they can catch fire, spreading through the ductwork systems to the entire building.

You need to produce a valid certificate, or this can leave you liable for a fire bill. Furthermore, you can also be issued fines if you fail to take precautions to ensure your ductwork systems are fire safe. Again, if you do not comply with this, you are liable to be fined.

What is TR19?

TR19 is the recognised industry standard for cleaning commercial kitchen ductwork. The TR19 initiative was implemented as a method of improving health and safety standards throughout the UK.

The main aim is to reduce fire risk and food contamination in commercial kitchen settings. TR19 provides guidelines for maintaining and testing commercial ventilation systems.

The TR19 standard is the level of quality that must be achieved when duct and kitchen extract cleaning systems are cleaned.

Insurance and building companies require this level to be reached when ductwork cleaning operations are underway. A TR19 certificate proves your business has taken essential precautions to help decrease unnecessary fire risks.

Clean extractor hoods are more efficient at removing steam, smoke, and smells from a kitchen. For ‘heavy use’ kitchens (12-16 hours), it is recommended that the units should be cleaned every three months to meet TR19 conditions.

Fire dampers are crucial passive fire protection products used in heating, ventilation, and air conditioning ducts to prevent the spread of fire inside the ductwork through fire-resistance rated walls and floors. These protect fire escape routes if there is a fire. In the event of a rise in temperature, the fire damper closes, usually activated by a thermal element. This melts at temperatures higher than ambient but low enough to indicate the presence of a fire, allowing springs to close the damper blades.

Fire dampers can also close following receipt of an electrical signal from a fire alarm system utilising detectors remote from the damper, indicating the sensing of heat or smoke in the building occupied spaces or in the duct system.

Whichever system you have, we will identify, locate and access all fire dampers in the building to ensure they are working correctly. Our fire damper testing staff are fully qualified to ensure that  fire damper testing requirements are met fully, and we can ensure your system is working at its most effective.

As they are open most, if not all of the time, it is vital to ensure that they will still close effectively when required. By providing a barrier beyond which the fire cannot pass, effective fire dampers save lives; so regular fire damper testing (known as drop testing) as well as fire damper cleaning and maintenance is both a legal requirement and a critical part of building fire safety management.

Swiftclean is one of the UK’s leading specialist buildings services providers offering a fire damper testing, cleaning and maintenance service, in accordance with BS 9999:2017. This recently updated guidance now specifies that all fire dampers should be drop tested, cleaned and maintained at least every year.

This is because normal use of the ventilation system gathers an accumulation of contamination on the fire damper and its operational parts.  This must be removed, and the fire damper tested regularly to ensure that it operates as designed, should a fire occur. In a healthcare setting, additional care is needed, so Swiftclean also complies with Health Technical Memorandum (HTM) 03-01: Specialised ventilation for healthcare premises Part B: Operational management and performance verification.  In care applications Swiftclean will help the client to agree a regular fire damper testing procedure with the local fire prevention officer.

Swiftclean is a reliable Essex fire damper testing company and prides itself on expert care and attention. All staff that conduct these tests are fully qualified to carry out these tests effectively. We’ll explain the process to you every step of the way and give our expert advice and recommendations based on what we find.  We will then suggest the next best steps  to take to ensure the safety of the building.

Fire damper testing should always be carried out by a qualified competent professional.

First and foremost, it can be difficult to identify, locate and access fire dampers during fire damper testing. Without expert testing, there is the risk that they can be missed or not maintained properly. When they are identified, they are often difficult to access which is essential to be able to check the blades inside the ductwork.

Once we have carried out your fire damper testing, you will receive a written report confirming your compliance with legislation BS 9999:2017. We recommend that this is kept on file as it includes  before and after photos of each fire damper and their location and damper number so you can provide this to a Safety Compliance officer if required to confirm the fire safety of your building.

To test if a fire damper is working efficiently, one of the team will release the fire damper manually to  ensure it closes fully. In cases of fire the high heat should release the fusible link and close the fire damper to prevent the fire spreading. It is important that the fire damper is reset correctly following testing, so it will work correctly in the event of a real fire.

Swiftclean commitment:

  • Identify and locate each fire damper
  • Retrofit access doors if any of these are inaccessible
  • Carry out fire damper testing, cleaning and drop testing and reset each fire damper
  • Provide accurate records of fire damper testing, cleaning and drop testing, including before and after photographs of cleaning
