How this guide was checked
On December 26, 2025, the FODMAP Gut Diet Editorial Team reviewed Costa Coffee's published menu or allergen information for the United Kingdom market. We compared 8 potential options and 9 higher-risk items with common FODMAP ingredient and portion concerns. This is a time-stamped ingredient review, not laboratory testing of the finished dishes.
Suppliers, recipes, serving sizes, and staff procedures can vary by location. Confirm the current ingredients before ordering. A FODMAP assessment does not establish allergy safety, gluten-free status, or freedom from cross-contact.

Cross-Contamination Warning

- Shared steaming wand for all milks
- Shared preparation areas for food
- Same display cases for all items
If you have severe sensitivities, mention this when ordering.
How to Order
For a safe coffee:
“Can I have a medium flat white with lactose-free milk please?”
Or:
“Americano with a splash of almond milk, please.”
For food questions:
“Do you have any gluten-free options? And can I see the ingredients?”
