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

Specialist Duct Cleaning
Conducted to TR-19 Standards

Grease extract ductwork is present in almost every non-domestic premises, serving as a highly effective system for the removal of grease, soot and ‘polluted’ air. These systems are highly susceptible to the accumulation of grease and debris by nature, with the potential to harbour dangerous levels of carbonised grease deposits. This means that without adequate and regular maintenance, the extraction system could become a fire hazard.

Regular duct cleaning and maintenance are two of the most important tasks across all commercial spaces – helping ensure both cleanliness and safety where employed correctly. Despite this importance, a lack of either accessibility often restricts the amount of duct cleaning conducted within commercial buildings – putting businesses across every sector at risk of closure or prosecution. Ingot services are proud to offer a fully tailored, cost-effective solution to this issue – specialist duct cleaning, conducted to TR-19 standards.

Undertaken by highly trained teams of registered Vent Hygiene Elite experts, Ingot’s duct cleaning service works to remove grease and soot from ducting of all varieties, helping ensure commercial spaces meet stringent health and safety regulation.

Commercial Duct 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 duct cleaning – which is subject to a number of restrictions surrounding both legality and insurance policy, many of which require commercial buildings to maintain a good supply of clean air.

With commercial hygiene laws and regulations – particularly TR-19 standards, the Food Safety Act 1990 and Health and Safety at Work Act 1974 – subject to regular enforcement, it is essential that businesses possessing ductwork systems ensure they are cleaned to TR-19 standards by BESCA qualified specialist at least once every two years, and that inspection is carried out on a regular basis. In addition to this, adequate and correctly formatted records of all duct cleaning work must be kept – including photographic evidence. Building owners or managers who fail to ensure sufficient ductwork cleaning may be unable to claim insurance in the event of an accident, or face prosecution.

Duct Cleaning FAQs

How often should kitchen ducts be cleaned?

While every two years is the default requirement for cleaning ventilation ductwork, some buildings may need more frequent cleaning, with most kitchen extract systems cleaning frequencies dependent on the amount of and type of use they undergo. 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

Outside of this, legal guidelines indicate that kitchen extract systems must be cleaned at least every two years.
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.

What is sick building syndrome?

‘Sick building syndrome’, a common issue for the occupants or users of school or office buildings, affects individuals in the form of repeated minor illnesses such as colds, flu and allergies. Whilst the causes of Sick Building Syndrome were unknown for a long period of time, it has now been shown to be a direct effect of poorly maintained ventilation systems. Ventilation systems left to harbour dirt and dust can become the home to potentially harmful particulates, meaning that when they are used, they have significant potential to spread dust and airborne microorganisms through a building. The Environmental Protection Agency has published studies showing that the air inside buildings can be as much as 70 times more polluted than the air outside where ventilation is not correctly maintained.

What is the process for kitchen duct cleaning?

The process for kitchen duct cleaning may vary significantly according to a number of factors, including the layout of ductwork requiring cleaning, and the company selected to perform the duct cleaning. Despite slight variation according to these two factors, industry standards - particularly BESCA’s TR-19 guidelines and regulations, have generally established a few ways in which ductwork should be cleaned. Generally, service providers make use of specialised tools, including purpose-designed brushes and cleaning substances to dislodge dirt and grease from deep within extract and ductwork systems, before vacuuming out all debris with a high-powered vacuum cleaner. In some cases, technicians may require additional access points to ductwork, or, where the cleaning of additional equipment such as canopies and fans are required, may take apart and reconstruct some elements of the ductwork system in order to ensure an optimal clean.

How do I know if my kitchen ducts need cleaned?

Generally, kitchen ducts should be cleaned on a regular basis, and in accordance with usage levels - typically every six months where experiencing moderate use, and every three where experiencing high levels of use. Where possible, it is often highly beneficial to monitor the levels of grease and debris within the internal workings of kitchen ducting. An increased or noticeable presence of grease is a good indicator as to when kitchen ductwork requires cleaning.

In addition to this, kitchen ductwork should be cleaned when mould is present, in the case of an infestation, where there is debris restricting airflow, or where the HVAC system is the cause of offensive odour.

For those unsure as to when or if their kitchen ductwork should be cleaned, Ingot Services are proud to offer a free, no-obligation consultation service, during which our Vent Hygiene Elite accredited experts will work to establish whether or not our services are needed.

Is cleaning kitchen air ducts worth it?

Air duct 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 duct 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 ductwork system.

In addition to keeping buildings across all sectors in line with legal and TR-19 standards, duct 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

Can I clean kitchen air ducts myself?

Though staff and non-qualified individuals may be able to ‘clean’ ductwork to an extent, in order for the system to be seen as clean in the eyes of insurers or industry regulatory bodies, a professional company registered with BESA and working to TR-19 standards must be hired to undertake a documented deep clean at least once every two years (but most commonly between once every three and six months according to kitchen usage).

Due to the complexity and positioning of much kitchen ductwork, achieving an effective clean as an untrained individual without specialist equipment proves incredibly difficult. Cleaning to TR-19 standards requires extensive training and experience, alongside access to purpose-built tools, such as a high-powered vacuum and rotary brushes. In addition to this, improper cleaning may even damage the ducts, resulting in potentially expensive repairs.

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.

Why is kitchen duct cleaning important?

Duct cleaning is an essential factor in maintaining the safety and legality of commercial kitchen spaces. With incorrectly maintained extract systems, including ductwork, 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 defence, 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 ductwork 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 duct cleaning typically experience compliance with the insurance conditions of all major providers and a reduced risk of infestation and contamination.

Why is TR-19 important?

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 extract systems are cleaned.

These standards are hugely influential to both owners of ventilation systems, and technicians offering ventilation and extract specific cleaning services. In the case of commercial kitchens, TR-19 works to ensure all elements of extract systems are cleaned and maintained to a high standard, significantly reducing the risk of fire caused or spread by significant levels of grease of fat deposit build-ups.

Many major insurers implement TR-19 standards as a condition within their policies, meaning non-compliant businesses may be unable to acquire insurance, or subject to high premiums.

How much does commercial kitchen duct cleaning cost?

The cost of commercial kitchen duct cleaning is highly dependent on a number of factors, including the size, layout, and type of ductwork requiring cleaning, the accessibility of said ductwork, whether your cleaning service is offered on a contractual or one-off basis, and your selected provider. As ductwork 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 ductwork cleaning requirements, and establish a price, which can be later sent over email.
