Commercial Kitchen Extract Cleaning Service

A nationwide supplier of specialist commercial kitchen extraction cleaning services

Extract cleaning – not your cup of tea, but our bread and butter.

The Gold Standard for
Commercial Extract Cleaning

Extract cleaning is one of the most important tasks in a commercial kitchen – and is generally required on a regular basis in order to minimise both health and safety risks. Though extract systems are amongst the most frequently used kitchen equipment, put in place to remove grease, steam, and other contaminants from the air surrounding appliances, they are often poorly maintained – as many prove inaccessible or too complex to be cleaned by staff.

With kitchen extract systems and their accompanying ducting posing a significant fire hazard when allowed to harbour oil and grease, and staff unable to provide sufficient levels of cleaning, professional assistance in the form of specialist extract cleaning is often required to maintain a safe, hygienic working environment, and to meet numerous legal requirements.

Ingot Services’ fully tailored kitchen extract cleaning service works to minimise the risk of fire and bacteria spread through the efficient and effective removal of all grease and debris build-up within extracts systems. Throughout this service, our fully qualified and accredited experts use specialist tools and fluids to access and effectively clean all aspects of the extract system, helping ensure kitchen spaces meet health and safety, TR-19, and EHO regulations, whilst creating a suitable internal environment for both customers, and staff.

Fully Tailored Service

As long-established industry experts, the Ingot Services team understand that scheduling a large-scale cleaning service can prove challenging for bustling commercial kitchens. That’s why we’ve worked to develop a highly flexible extract cleaning format, available on both a one-off, and regular service, and both within, and outside of working hours, causing minimal disruption.

Regular Extract Cleaning

Our regularly scheduled kitchen extract cleaning service is highly suited to commercial kitchens subject to frequent use. This service ensures all all aspects of the extract system – including ducting and canopies – are cleaned to an optimum level, minimising risk of fire, and helping create a hygienic working environment.

Whilst legal requirements state that extract systems must be cleaned at once every two years, many kitchens subject to frequent use may require a more regular service. Ingot’s qualified experts are happy to assist in establishing a suitable extract cleaning frequency for your commercial kitchen via consultation call.

One-Off Extract Cleaning

Whilst regular extract cleaning offers a convenient way to stay on top of both cleaning and regulation, one-off cleans can be arranged at any time, and may be especially appropriate for those;

  • Taking over a new kitchen
  • At the beginning and/or end of a period of disuse (e.g. start/end of summer season)
  • Experiencing higher usage has than normal

Professional Certification Provided

Whilst kitchen extract cleaning is a challenging task for staff lacking TR-19-specific knowledge or skillsets, businesses across the UK seek the assistance of specialist cleaning teams for one overriding reason; evidence.

The vast majority of insurers offering policies covering commercial kitchens put forward stringent conditions surrounding regular cleaning of high-risk areas and appliances. As extracts are often cited as a key contributor to highly destructive fires, many insurers insist on their regular cleaning to TR-19 standards by a registered professional – of which there must be adequate evidence in the form of documentation.

Ingot Services’ are proud to offer all necessary paperwork and documentation, alongside a certificate, upon the completion of any of our services, helping ensure your business’ compliance with both insurance policy and TR-19 requirements.

Extraction and Ducting Cleaning

Legislation and Requirements

Ingot Services understand the importance of high-quality commercial cleaning – particularly where specialist knowledge, skills, and equipment are required. This is especially relevant to extraction cleaning- which is subject to a number of restrictions surrounding both legality and insurance policy as a result of the high probability of significant fires caused by or spread through poorly maintained kitchen extract systems.

With commercial laws and regulations – particularly the Regulatory Reform (Fire Safety) Order 2005, TR-19 regulations, and the Safety at Work Act 1974 – subject to regular enforcement, it is essential that all commercial kitchens – from those serving local cafes to Michelin Star restaurants – must actively adhere to stringent regulation surrounding both general safety, and specific maintenance regiments in order to operate safely, and without legal consequence – especially where equipment with a significant impact on fire safety is concerned.

Ingot Services’ wide range of specialist cleaning services works to ensure the safety of all ducting, canopy, and extract systems, offering a number of solutions – from biennial Vent Health Elite accredited duct cleaning, to regularly scheduled canopy cleaning, our offerings are built to satisfy legal requirements and obligations. In addition to this, correctly implemented extract and ventilation cleaning can bring a number of benefits to commercial kitchens, including;

Extract Cleaning FAQs

How often should a commercial kitchen extract be cleaned?

The frequency at which your kitchen extract should be cleaned is highly dependent on a number of factors - primarily the amount of daily use experienced by the extract system. Whilst many legal requirements stipulate that extract cleaning should be undertaken by accredited professionals at least once every two years, most kitchen systems will require more frequent cleaning in order to stay in line with health and safety regulations.

In order to determine the ideal rate of cleaning, many measure the rate of grease and dirt build-up within extract system ductwork, however, if this is not possible, the following is generally suggested;

Kitchens undergoing consistent heavy use: clean every three months

Kitchens undergoing moderate use: clean every six months

If in doubt, the best option is to arrange regular tests and inspections and take advice from an HVAC professional about whether cleaning has become necessary. Outside of this, Ingot Services are proud to offer a free, no-obligation consultation service, during which our duct cleaning experts will work with you to establish the best ductwork cleaning frequency for your kitchen should regular cleaning be required.

How much does kitchen extract cleaning cost?

The cost of commercial kitchen extract cleaning is highly dependent on a number of factors, including the format and accessibility of the extract system in its entirety (including canopy, fan, and ductwork), whether your cleaning service is offered on a contractual or one-off basis, and your selected provider. As kitchen extract cleaning requirements can vary so significantly, the vast majority of service providers will charge within a set price range according to individual circumstance.

Ingot services are proud to offer our clients a free, no-obligation consultation, during which we’ll evaluate your extract cleaning requirements, and establish a price, which can be later sent over email.

How long does kitchen extract cleaning take?

The amount of time taken to complete a commercial kitchen extract clean can depend on a number of factors, including the scale and accessibility of the extract system, the method most suitable for cleaning, and the provider selected to perform the service.

Even a short cleaning job may seem like a long period of time for your kitchen to be ‘out of action’. Ingot works to minimise this disruption. We are proud to offer a fully tailored service, available on a 24-hour basis, meaning cleaning can be undertaken during regular hours of closure.

Why is kitchen extract cleaning important?

Extract system cleaning is an essential factor in maintaining the safety and legality of commercial kitchen spaces. With incorrectly maintained extract systems, including cited as the cause or a significant factor in the spread of highly destructive fires within commercial kitchen environments, specialist cleaning is able to act as a significant line of defense, working to remove grease and fat deposits responsible for encouraging the spread of fire through the system.

For this reason, all industry and legal regulations, including TR-19, require kitchen extract cleaning to be undertaken by accredited professionals on a regular basis, helping ensure the optimal safety of the working environment, and those within it.

In addition to this, commercial kitchens undergoing regular extract cleaning typically experience compliance with the insurance conditions of all major providers and a reduced risk of infestation and contamination.

What are TR-19 standards?

TR-19 currently stands as one of the most important industry standards for ventilation cleaning. Defined by BESA in 1988, TR-19 guidelines and regulations, particularly part 7, work to standardise the way in which duct and kitchen extract systems are cleaned.

Relevant to both cleaners, and building owners, TR-19 has become the standard to which the vast majority of insurers require work to be completed to. This makes selecting a fully qualified and competent cleaning contractor more important than ever business and building owners across a number of sectors.

Ingot services are proud to offer commercial kitchen extract, duct, and fan cleaning services, conducted to TR-19 standards by Vent Hygiene Elite accredited technicians.

Is there a legal requirement for extract cleaning?

Extract system cleaning is significantly influenced by the Regulatory Reform (Fire Safety) Order 2005. This reform states that all elements of commercial extract systems must be included in fire risk assessments, and that, in accordance with this, suitable action must be taken to minimise the fire risk to the building and its occupants. Suitable action includes establishing a regular extract cleaning schedule, conducted and evidenced by accredited, professional technicians.

In addition to this, failure to maintain and clean commercial kitchen extract systems on a regular basis may result in the business or building’s breach of Environmental Health regulations, potentially leading to the invalidation of your fire insurance policy, prosecution, or closure.

What is a Grease Hygiene Technician?

Grease Hygiene Technicians, also referred to as GHTs, are key individuals in the commercial kitchen extract cleaning process. When officially accredited by BESCA, GHTs are able to complete and certify all aspects of extract and ventilation cleaning to TR-19 standards. This work may include canopy, ductwork, extractor fan, and grease extract unit cleaning.

GHTs are also able to effectively prepare the work location prior to the commencement of any cleaning activities. In addition to this, in order to achieve and maintain their BESCA GHT accreditation, all grease hygiene technicians must have the necessary skills to ‘cut and insert suitable access panels’, and perform approved, effective cleaning methods in line with industry and TR-19 standards.

What is a kitchen extract system?

Extracts are essential to the function of all commercial kitchens. Working to maintain a hygienic, safe, and functional working environment, extract systems (typically composed of a canopy, accompanying ductwork, and extractor fan) remove airborne 'contaminants' such as grease, smoke, heat, odours, and steam produced as a result of cooking, typically carrying them from the air surrounding kitchen appliances to be dispersed outside of the building.

Though highly effective in maintaining a safe working space in commercial kitchens, extract systems, when incorrectly maintained, can prove dangerous. Prone to build-ups of fat and grease within their ductwork, extract systems are listed as the cause of, or a significant factor in the spread of fires. Regularly schedules professional extract cleaning provides a comprehensive solution to this issue.

What is a TR-19 certificate?

TR-19 certificates are an essential element of all ductwork and extract cleaning services. When completed correctly by an accredited service provider such as Ingot, a valid TR-19 certificate (and accompanying documentation) serves as evidence of all cleaning work undertaken, proving that your extract system has been cleaned and degreased in line with all BESCA standards, and are safe to use.

This certificate is highly beneficial to companies and building owners looking to obtain insurance - as many major providers list TR-19 compliance amongst their top conditions for commercial spaces with extract systems, such as kitchens. In the event of a fire determined to be started in, or spread by the extract system, most will demand proof of cleaning in the form of a TR-19 cleaning certificate. Those without one may be held liable for fire damage.

Is extract cleaning worth it?

Extract cleaning is not just ‘worth it’, but in most cases (especially within commercial kitchens) a legal requirement for non-domestic properties. In spaces held to TR-19 standards, a professional company able to perform extract cleaning to a number of set standards, and to provide certification and documentation acting as evidence of cleaning undertaken must be hired at least once every two years to ensure the cleanliness and safety of the extract system.

In addition to keeping buildings across all sectors in line with legal and TR-19 standards, regular extract cleaning offers the following benefits to commercial kitchens:

- Reduced fire risk

- Decreased risk of infestation

- Insurance compliance

- Reduced risk of closure and prosecution

- Improved safety levels for all building users
