The company OvenKing Nationwide (OKN) provides bespoke professional cleaning services to the catering industry. The three main services OKN provide can be categorised as;

●Total kitchen deep cleaning
●Kitchen appliance cleaning
●TR19 compliant HVAC duct cleaning

All three services are required to maintain the adequate safety of staff and customers. When commercial kitchens are not cleaned properly hygiene issues will ensue, and the health of the general public is at risk. Appliances such as ovens, fryers and microwaves all pose safety risks to staff if not maintained properly and the build up of grime poses a fire risk. HVAC ducting including filters, fan and hood are all designed to safely extract airborne particles and build up of these deposits are a serious fire risk.

Total Kitchen Deep Cleaning

Commercial Kitchen staff should have the training and ability to perform basic cleaning duties in the kitchen to maintain the hygiene. However this is not always the case. Due to the demands placed upon staff in a busy kitchen and staff turnover rates prevalent in the catering industry staff may not have time, training or inclination to complete the adequate cleaning schedule. This lack of cleaning is evidenced by the fact that in Bournemouth alone 76 (of 1,874) food serving premises have a hygiene rating of 2 or lower. Source: ScoresOnTheDoors.org.uk, and correct as at 29th March 2015.

A hygiene rating of 2 indicated that the Environmental Health Officers who inspected the premises believe the hygiene needs immediate improvement. A rating of 1 indicated the premises needs immediate and serious improvement. Any premises receiving a rating of 0 will be shut immediately.

Hygiene ratings must also be clearly displayed in the premises and are updated every 6-36 months as specified by the Food Standards Agency. If an establishment received a poor hygiene rating the details are posted on the SoresOnTheDoors website and within their own premises. A poor score will have a negative effect on business at least until the premises is inspected and assessed again.

For every time the adequate cleaning routine is not followed correctly it will make it harder to bring the kitchen up to the required hygiene standard.

Kitchen Appliance Cleaning

OKN is an off shoot of OvenKing which provides a domestic oven cleaning service. This domestic oven cleaning service can be replicated within a commercial kitchen albeit on a larger scale. The cleanliness of commercial ovens and other kitchen appliances will not only affect the overall hygiene of the kitchen but regularly cleaning appliances will extend their useful life. The build up of grease, fats and other contaminants also pose a fire risk, which puts staff, customers and the establishment owner’s investment at risk.

From an aesthetics perspective with many commercial kitchens now having a front facing kitchen (one that can be seen by customers), it is of prime importance for the establishments management to ensure appliances are kept clean inside and out so as to attract and retain business.  Kitchen appliance cleaning in commercial kitchens is a service that OvenKing has provided since before OKNs inception. Particularly for mobile catering operations such as hog roast businesses whose equipment is on show each time they work.

TR19 Compliant HVAC Duct Cleaning

TR19 (also sometimes written as TR/19) are the requirements by which HVAC systems should be maintained and is the leading guidance document issued by the B&ES Association; British Standard and European Norm BSEN: 15780; and BG49/2013, BSRIA’s guide on Commissioning Air Systems. OKN provides a duct cleaning service to the catering trade that is compliant with TR19 recommendations. Part of this service includes issuing TR19 certification for the duct systems. But only once OKN has cleaned the ducting and inspected the post clean condition. Since the introduction of TR19 and that of its predecessors it has been a mandatory requirement for all business possessing HVAC systems to maintain them to this standard.

Building managers or the person responsible for the HVAC system, which often in the terms of the lease for the property is delegated to the owner of the business in occupation at the premises in question, can be prosecuted if they are not able to provide evidence that the ducting is maintained to the TR19 standard.

It is also now becoming more common for the insurers of the buildings and businesses that have HVAC systems to want to see copies of TR19 certificates before they will provide insurance coverage. This ensures OKN receives a steady stream of leads and will only increase across the industry.

Aside from the risk of prosecution and unavailability of business insurance without TR19 certification dirty air ducts and ventilation systems can affect the smells and fumes given off by a catering premises which could also affect future or pending town planning applications and lease renewal negotiations. This may also affect staff moral and customer/public perception of the business.

Airborne contaminants can also ruin interior decorations and exterior decor, damage business computer equipment, and cause a high capital expenditure risk if replacement of prematurely deteriorated air conditioning systems is required there is also the risk of a high dilapidation charge when vacating a business premises.


All the services that OKN provide can be sold on a standalone service or bundled with the other commercial cleaning services. OKNs business model means that the cleaning services can be tailored to the exact requirements of the establishment, including providing cleaning services out of hours so as not to disturb the trade of the client. Services are also provided on a payment up front basis, Regular and reliable clients can of course be offered credit facilities of some description to encourage repeat business.

The services OKN provide cannot be replicated by the catering establishments themselves without significant investment in training and equipment for services they require only 1-3 times per year.  The processes OKN have developed and refined would not easily be replicated without much trial and error. These reasons all also act as a barrier to entry into this industry for any other potential business, OKN has the correct insurance coverage, staff training, cleaning processes, industry knowledge, tried and tested tools, compliant chemicals, equipment and labour availability.

From a legislation perspective further legislation would likely only tighten hygiene regulations which would be to the benefit of the OKN business model and create further barriers to entry to the industry.
