Deep Clean Kitchen Service

A clean, hygienic kitchen doesn't just look great, it's an essential part of any modern food business. Regular deep cleans of equipment, fixtures and fittings, including your grease extraction system and grease trap, are a vital part of every commercial kitchen's maintenance routine.

What Is Kitchen Deep Cleaning?

Kitchen deep cleaning goes above and beyond standard daily cleaning schedules. Hard to clean areas where oil, fat and grease deposits congeal on surfaces can be missed and become a potential breeding ground for bacteria and mould. It involves the physical and chemical removal of cooking by-products such as fats, oils and grease (collectively known as F.O.G), burnt carbon and everyday kitchen waste that is inaccessible or hard to clean daily. 

A regular, professional deep cleaning programme is vital for maintaining a high standard of kitchen hygiene and is a critical part of your legal obligations. This helps your business comply with key legislation, including the Food Safety Act 1990, which makes it an offence to supply food that is unsafe. Furthermore, the Food Hygiene Regulations 2006 require you to implement a food safety management system, such as HACCP, where a clean environment is a fundamental prerequisite. Adhering to established industry guidelines, for example, BESA's TR19 for the internal cleanliness of ventilation systems, is also crucial for reducing fire risk and is often a requirement of insurance policies.

What Happens During a Kitchen Deep Clean

Modern kitchens contain a range of complex cooking equipment, each with its specific cleaning requirements. Grease removal from a hood is very different to removing burnt-on carbon deposit on a grill, or maintaining and cleaning a grease trap. A thorough, professional kitchen deep clean will often comprise:

  • Degreasing and sanitisation of walls, floors and ceilings
  • Meticulous cleaning of cooking  equipment such as ovens, grills and fryers
  • Waste trap maintenance
  • Surface disinfection of shelving, racking and food prep surfaces
  • Kitchen odour elimination
  • Kitchen ventilation, duct and hood cleaning to TR19 standards
  • Cleaning of fixtures and appliances such as light fittings, fridges and freezers

Following inspection by the local authority, a business will be rated on a scale of 0-5. The lowest rating being ‘0’, meaning urgent improvement is required. Whilst the top rating ‘5’ means that the hygiene standards at an establishment are very good. A commercial kitchen deep clean is a part of improving a food premises' FSA rating.

**TR19 Grease

The accumulation of grease within extraction systems and ducting can diminish airflow and increase the risk of fire. TR19 is a recognised standard for measuring grease levels and identifying recommended cleaning frequencies, which are designed to reduce the risk of fire and are tailored to your system. Regularly clearing grease deposits can promote a good working environment by taking away heat from cooking to maintain a good supply of airflow and reduce the risk of kitchen fires. All of our kitchen ventilation cleans are carried out to be TR19 compliant, including full certification for insurance purposes.

Frequently Asked Questions


  • What does a kitchen deep clean include?

    A kitchen deep clean involves a thorough, professional cleaning of all areas where grease, food particles, and bacteria can accumulate especially in hard-to-reach spaces. This includes:

    • Degreasing of canopies, ductwork, and extractor fans
    • Cleaning of ovens, hobs, grills, fryers and other cooking equipment
    • Grease trap maintenance
    • Ventilation duct cleaning in line with TR19 standards
    • Sanitisation of walls, floors, and high-touch surfaces

    This level of cleaning helps ensure fire safety compliance, improved airflow, and a hygienic environment for food preparation.


  • What are TR19 regulations?

    TR19 is a guidance document developed by the BESA (Building Engineering Services Association) that outlines industry best practices for cleaning ventilation systems, particularly in commercial kitchens.
    TR19 compliance is essential for:

    • Reducing fire hazards from grease-laden ducts
    • Meeting insurance requirements
    • Passing Environmental Health inspections
    • Supporting your Food Standards Agency (FSA) hygiene rating

    Our TR19-certified kitchen ventilation cleaning services ensure your premises meet all regulatory and food safety standards.


  • How often should I clean commercial kitchen ducts?

    Kitchen extraction systems and ducts should be professionally cleaned:

    • Every 3 months for high-volume kitchens (e.g. takeaways, large restaurants)
    • Every 6 months for moderate-use kitchens (e.g. cafés, pubs)
    • Annually for low-use settings (e.g. community centres)

    How often you should be cleaning may also depend on insurance policies and risk assessments. Regular cleaning of extractor hoods and ventilation ducts helps prevent grease buildup, maintains air quality, and reduce fire risk.


  • Can a kitchen deep clean reduce fire risk?

    Absolutely. Commercial kitchen deep cleaning plays a critical role in fire risk prevention by:

    • Removing highly flammable grease deposits from hoods, fans, and ducting
    • Ensuring compliance with TR19 fire safety standards
    • Minimising the chance of ignition in extractor systems

    By keeping extraction units and cooking equipment clean, you reduce the likelihood


  • How long does a deep clean take?

    The duration of a kitchen deep clean depends on the size and condition of your kitchen, but most cleans typically take:

    • 4 to 8 hours for small to medium kitchens

    • TR19 compliance for ventilation hygiene
    • Insurance policy terms

    Failure to maintain a clean kitchen can lead to fines, FSA hygiene rating drops, or even closure in severe cases. Routine professional cleaning supports legal compliance and demonstrates a proactive risk management strategy.


  • How many visits does a deep cleaning take?

    In most cases, one visit is sufficient for a full kitchen deep clean. However, multiple visits may be required if:

    • The site is particularly large or heavily soiled
    • You need TR19-compliant duct cleaning and grease trap maintenance as separate services.
    • Cleanings are staged to align with operational hours

    Our team will assess your needs during a free hygiene survey and recommend a tailored cleaning schedule.
