Under building regulations Part H section 2.21, it specifies that “drainage serving kitchens in commercial hot food premises should be fitted with a grease separator complying with prEN 1825-1 and designed in accordance with prEN 1825-2 or other effective means of grease removal”.

This needs to be entered into the grease trap calculator to accurately work out the required nominal size grease management system.
