Catering is always standard-rated at 20%
Every supply made by a caterer is a catering supply and is standard-rated at 20% regardless of the food involved. This is a material distinction from retail cold food, which is generally zero-rated. A caterer who treats certain food lines as zero-rated because those products would be zero-rated in a shop is misapplying the VAT rules. Recharged staffing, hire equipment and transport that form part of the catering service are part of the same standard-rated supply. See gov.uk/guidance/catering-takeaway-food-and-vat-notice-7091.
