Commercial Kitchen Drain Blockage Prevention Service

Commercial kitchens are fast paced and bustling environments where everything needs to happen smoothly and efficiently, to ensure customers have an enjoyable dining experience. A blocked or overflowing drain in the middle of peak time is a recipe for disaster, and the last thing a chef or restaurant owner/manager wants.

As well as being imperative for the smooth running of a commercial kitchen, several regulations and legislation form part of the owners' and proprietors' duty of care for managing and disposing of F.O.G (fats, oils and grease) produced as part of their business operations.

  • The British Building Regulations (document H, section 2.21), commercial food premises state regulations for grease management. Under these regulations, a commercial food premises connected to the mains drainage system serving hot food should be fitted with a grease trap or separators complying with BS EN 1825-1:2004. Grease traps and interceptors must be provided by law to a range of facilities, including restaurants, cafes, fast food restaurants, food processing, and commercial kitchens.
  • Under the Water Industry Act 1991, it is a criminal offence to discharge any matter that may interfere with the free-flowing of wastewater into public sewers systems.
  • Every commercial premises is also responsible for arranging the collection and disposal of waste (including waste cooking oils and fats). It must comply with the requirements of Section 34 and Duty of Care of the Environmental Protection Act 1990.
  • The Food Safety Act 1990 states that drainage problems or blockages caused by the effects of F.O.G within drains that result in failure to comply with the Food Hygiene Regulations could lead to prosecution, fines or imprisonment or give grounds for an emergency prohibition order.

Rentokil Specialist Hygiene are a UK leader in preventative services for commercial kitchen drains, keeping Britain's kitchens safe, compliant and hygienic.

Why Drain Blockage Prevention is Essential in Commercial Kitchens

Commercial kitchens handle high volumes of F.O.G, and food waste daily — all of which can build up and cause major drainage issues. Blocked or poorly maintained drains can quickly lead to:

  • Flooding and downtime in your kitchen - The last thing staff want to be doing is dealing with an emergency flood with a full restaurant.
  • Foul odours and pest attraction - Flies and cockroaches are a shortcut to poor hygiene inspections and customer reviews. Foul smells will quickly deter repeat custom.
  • Non-compliance with food hygiene regulations - Not dealing with or preventing unsanitary conditions from flooded drains can be an example of negligence under the Food Safety Act 1990 (and General Food Hygiene Regulations 2013)
  • Non compliance with Building Regulations, that mandate effective management of fats, oils, and grease (F.O.G) to protect public sewers and prevent environmental harm.
  • Costly repairs and pipe replacement - Blocked pipes can quickly turn to burst pipes, and grease in pipework is notoriously difficult to remove once solidified
  • Health and safety risks for staff - Slip hazards from grease spills, or biohazards from blocked drains. Both are less than ideal in a busy commercial kitchen.

By working with Rentokil Specialist Hygiene, you can prevent these issues before they happen and ensure your business runs smoothly and compliantly.

Frequently Asked Questions


  • What causes commercial kitchen drain blockages?

    The primary cause is F.O.G (fats, oils and grease) being incorrectly poured down drains. These can quickly solidify and cause a bottle neck that gets worse with time.


  • How often should kitchen drains be cleaned?

    As an average, commercial drains should be cleaned thoroughly at least every six months, but this can vary depending on the condition of the drain, and what's being put down it.


  • Do you offer emergency spill clean-ups?

    Yes we do! Our specialist cleaning teams are available round the clock to attend to emergency spills or clean ups.


  • How do I know if my kitchen drains are at risk of blockage?

    It's a good idea to have a drain inspection to identify unseen hazards. A build up of grease and other blockages can go unseen until it's too late.


  • What happens to waste removed during kitchen drain cleaning?

    All waste, including waste trap grease, is removed from site and disposed of responsibly and legally.
