As summer comes to an end, many commercial kitchens are entering an important period for planned maintenance. Restaurants, pubs, hotels, care homes and other food-service businesses have often experienced increased activity throughout the warmer months, putting additional demand on their kitchen extraction systems.

Every busy service can contribute to the gradual build-up of grease within an extraction system. Although the canopy and filters may be cleaned as part of the normal kitchen routine, grease can also travel further into the ductwork, where it is much harder to see and remove. By the time autumn arrives, a system that appears reasonably clean from the kitchen can have significant deposits within areas that are hidden from everyday view.

This is why late summer and early autumn can be a sensible time to review your commercial kitchen extraction cleaning requirements.

Duct Cleaning Tip Top Ltd provides professional kitchen extraction and duct cleaning services across West Sussex, Hampshire and the South Coast. Our work is carried out with reference to BESA TR19 guidance, with Duct Cleaning Tip Top listed on the BESA Vent Hygiene Register. The company is also now CHAS Elite accredited, providing clients with additional assurance around our approach to health and safety and contractor management.

Why kitchen extraction systems need professional cleaning

A commercial extraction system has an important role within a working kitchen. It removes heat, smoke, vapour and grease-laden air generated during cooking and helps maintain a more suitable working environment.

Cooking methods such as frying, grilling and roasting can produce significant quantities of grease vapour. Some of that grease is captured by the filters, but not all of it remains there. Fine grease particles can pass into the extraction system and settle on internal surfaces as the air moves through the ductwork.

Over time, these deposits can become substantial.

The difficulty for many kitchen operators is that most of the extraction system is hidden. Cleaning the visible canopy and changing the filters does not necessarily mean that the complete extraction system is clean. Internal ductwork, bends, access sections and extraction fans can all require attention depending on the design and condition of the installation.

Professional kitchen duct cleaning is therefore very different from routine kitchen cleaning. The purpose is to address contamination within the extraction system itself and to leave the business with appropriate evidence that the work has been undertaken.

Understanding TR19 kitchen extraction cleaning

TR19 is BESA industry guidance covering ventilation hygiene, including the specific considerations associated with grease extract systems in commercial kitchens.

For businesses responsible for a commercial kitchen, working with a contractor familiar with TR19 provides a structured approach to maintaining the extraction system. The cleaning process should take into account the construction of the system, the level of grease contamination, access requirements and the way in which the kitchen operates.

It is also important to understand what a TR19 cleaning service actually means. A contractor should not simply describe a service as "TR19 certified" without explaining what standard of work is being provided and what documentation will be supplied afterwards.

At Duct Cleaning Tip Top, we focus on the physical condition of the extraction system as well as the documentation that follows the work. Where appropriate, photographic evidence can demonstrate the condition of the system before and after cleaning, while the completed documentation provides the client with a record for their maintenance and compliance files.

The certificate is useful evidence, but the quality of the cleaning itself remains the most important part of the process.

Why autumn is a good time to arrange a professional clean

For many businesses, the end of summer provides a natural opportunity to review kitchen maintenance.

Hospitality venues can experience particularly high levels of activity during the summer. Longer opening hours, increased customer numbers and additional cooking can all place greater demands on extraction equipment. The result can be an increased accumulation of grease inside the system.

Once the summer period is over, arranging an extraction clean can help businesses enter the autumn and winter months with their maintenance programme up to date.

This does not mean that every commercial kitchen should automatically be cleaned in September. Cleaning frequency should reflect the individual system, the type and volume of cooking and the level of grease produced. A high-output restaurant will have different requirements from a smaller kitchen with limited cooking activity.

However, if your last professional extraction clean was some time ago, or your kitchen has been particularly busy over the summer, early autumn is an ideal opportunity to check your records and establish whether the system is due for attention.

Planning the work before the busier winter period can also make it easier to arrange access without unnecessary disruption to normal kitchen operations.

BESA Vent Hygiene Register and professional standards

Choosing the right contractor is an important part of maintaining a commercial kitchen extraction system.

Because much of the ductwork is concealed, it can be difficult for a customer to judge the quality of the work simply by looking at the kitchen after the contractor has left. This makes contractor competence, appropriate procedures and reliable documentation particularly important.

Duct Cleaning Tip Top Ltd is a member of the BESA Vent Hygiene Register. This is relevant to our specialist ventilation hygiene work and provides an independent indication that the company operates within an established industry framework.

Our clients can therefore engage a contractor with specific experience in ventilation hygiene rather than relying on a general cleaning company that may not specialise in commercial extraction systems.

For businesses with their own procurement procedures, contractor approval requirements or facilities management systems, this distinction can be particularly important.

Duct Cleaning Tip Top is now CHAS Elite accredited

Duct Cleaning Tip Top has also achieved CHAS Elite accreditation.

CHAS Elite and BESA Vent Hygiene Register membership serve different purposes. BESA VHR is directly relevant to ventilation hygiene competence, while CHAS provides independent assessment of contractor health and safety standards and management systems.

For commercial clients, having both provides a broader level of contractor assurance.

It is particularly relevant when a restaurant group, hotel, care organisation, facilities management company or property manager needs to demonstrate that contractors working on site have been appropriately assessed.

Our aim is to make the process straightforward for clients, from the initial assessment of the extraction system through to the completion of the cleaning work and the provision of the relevant documentation.

What professional kitchen duct cleaning involves

The exact cleaning process depends on the design and condition of each extraction system. No two commercial kitchens are necessarily the same, so the scope of work should be established before cleaning begins.

A professional clean can involve the accessible parts of the canopy, filters, ductwork and extraction fan, with the appropriate method selected according to the contamination present and the construction of the system.

Access is particularly important when cleaning ductwork. Hidden sections cannot be properly cleaned if there is no suitable way of reaching them. Where access is required, the contractor should consider the existing access arrangements and the practical requirements of the installation.

The aim is to remove grease and other accumulated contamination from the internal surfaces rather than simply improving the appearance of the visible equipment.

Once the work has been completed, appropriate documentation and photographic evidence can provide the client with a clear record of what was undertaken.

Why documentation matters to commercial kitchens

Professional extraction cleaning is not only about the day the contractor arrives on site.

Commercial kitchens often need to maintain records showing that important maintenance and cleaning activities have been completed. These records can be useful when dealing with facilities managers, landlords, insurers, auditors or other parties responsible for the premises.

A properly documented extraction clean gives the business evidence of when the system was serviced and provides a reference point for planning future maintenance.

For this reason, it is worth asking a contractor what documentation will be provided before booking the work. A simple invoice stating that the ducts were cleaned does not provide the same level of information as a properly documented professional service.

Prepare your kitchen extraction system for autumn

After a busy summer, autumn is a practical time to look beyond the visible areas of the kitchen and consider the condition of the extraction system itself.

If grease has accumulated within the ductwork, leaving it untreated is unlikely to improve the situation. Regular professional cleaning helps businesses maintain their extraction systems and keep appropriate records of maintenance.

Duct Cleaning Tip Top Ltd provides commercial kitchen duct cleaning and extraction cleaning throughout West Sussex, Hampshire and the South Coast. Our work follows the principles of BESA TR19 guidance, supported by our BESA Vent Hygiene Register membership and our new CHAS Elite accreditation.

If you are unsure whether your kitchen extraction system is due for cleaning, we can assess the system and discuss the most appropriate approach for your premises.

With the summer season coming to an end, now is a good time to review your extraction maintenance rather than waiting until the system becomes a problem.

Professional kitchen duct cleaning, carried out with the right standards and documentation, helps keep your commercial kitchen prepared for the months ahead.
