Choosing the correct grease trap size is important for maintaining effective grease management in commercial kitchens. If a grease trap is too small, fats, oils and grease can pass into the drainage system, causing blockages, unpleasant odours and costly drainage problems.
This grease trap sizing calculator helps estimate whether your kitchen may require:
based on common factors found in commercial kitchens.
Use the calculator below to get guidance on the type of grease management system that may be suitable for your kitchen.
This calculator provides guidance based on factors that influence grease production and wastewater flow in commercial kitchens.
These may include:
These factors can affect how much grease enters the drainage system and therefore influence the type of grease management system required.
The calculator uses common grease management principles and references industry standards such as BS EN 1825, which relates to grease separator systems used in commercial kitchens.
Installing the correct grease management system helps:
Commercial kitchens that produce high volumes of grease may require automatic grease recovery systems rather than traditional passive grease traps.
Using the correct grease trap size ensures grease is separated effectively before wastewater enters the drainage network.
In some kitchens a passive grease trap may be suitable for managing grease.
However, where water flow is higher — for example where pre-rinse spray hoses are used — an automatic grease recovery unit is often recommended to provide continuous grease separation.
Automatic systems are commonly used in:
The type of grease trap required for a commercial kitchen depends on several factors including wastewater flow, kitchen usage and sink configuration.
Smaller kitchens with lower water flow may be able to use a passive grease trap to separate fats, oils and grease before wastewater enters the drainage system.
However, kitchens that produce higher wastewater flow — particularly where pre-rinse spray hoses are used — often require an automatic grease recovery unit. These systems continuously separate and remove grease, helping maintain reliable drainage performance in busy commercial kitchens.
The correct system may also depend on factors such as:
The GreaseAway calculator above provides guidance based on these factors to help determine whether a passive grease trap, biofluid dosing or automatic grease recovery system may be suitable for your kitchen.

The results provided by this calculator are for guidance only and are based on the information entered. Final grease management requirements may vary depending on kitchen layout, drainage configuration and local authority requirements.
A site survey may be required to confirm the most appropriate grease management system.
