Standards guide

BS EN 1825 grease trap sizing guide in plain English

Most kitchens do not need a standards lecture. They need to understand what BS EN 1825 actually influences, what it does not answer on its own and why a site review can still matter before choosing a system.

What this guide is for

The standard helps shape sizing, but it does not remove the need for site judgement

Standards matter, but a kitchen can still end up with the wrong solution if someone focuses on a headline figure and ignores access, servicing practicality, layout or the real grease load.

What to keep in mind

The practical points behind the standard

  • BS EN 1825 is part of the sizing and selection conversation, not a substitute for understanding the actual site
  • Kitchen output, menu type and grease load still matter in real-world recommendations
  • Drainage layout, access and maintenance practicality can affect what is sensible on the ground
  • A standard can guide the decision, but a poor site fit can still create problems later

Practical takeaway

A good recommendation usually blends standards, site review and common sense

The strongest outcome usually comes from combining the relevant sizing logic with an honest view of the kitchen, drainage arrangement and what will be practical to maintain long term.
