Street food margins in the UK are squeezed by pitch fees, packaging, and unpredictable footfall. You protect profit by standardising portions and pricing with a buffer for slow days.
Quick Summary
- Portion standards beat guesswork
- Compostable packaging is real COGS
- Keep a short menu with shared ingredients
- Review prices monthly
The Core Cost Formula
Cost per item = Ingredients + Packaging + Condiments
Food cost % = Cost per item ÷ Price
If the portion moves, the margin moves.
