Quick answer
For allergens, always use the official Greggs allergen information on greggs.com and speak to staff, because recipes change and shops share kitchens and equipment.† This page explains how to check, not which items are safe.
The 14 major allergens in the UK
- Celery, cereals containing gluten and crustaceans
- Eggs, fish and lupin
- Milk, molluscs and mustard
- Nuts, peanuts and sesame seeds
- Soya and sulphur dioxide (sulphites)
How to use the official information
- Open the allergen guide on greggs.com.
- Search each item you plan to order.
- Check the date and recent changes.
- Ask staff about cross-contact and preparation.
- If unsure, do not eat it.
Cross-contact
Bakes, sandwiches and desserts are prepared in shared spaces, so any allergen may be present in small amounts. See gluten free and the vegan menu for diet-specific advice.†
Heads upThis page is not allergy advice. Use official sources and medical guidance.
Questions to ask staff
- Is this item made with milk, egg, wheat, soya, nuts or sesame?
- Is it prepared on shared equipment?
- Has the recipe changed recently?
- Can you show me the allergen information for this exact item?
What the law says about pre-packed food
In the UK, food pre-packed for direct sale must list ingredients with allergens emphasised, a rule often called Natasha’s Law. Loose food sold over the counter is treated differently, so you should always ask.†
Reading allergen labels on pre-packed items
Pre-packed sandwiches, salads and snacks carry a label with ingredients and allergens in bold or otherwise emphasised. Read the label each time, because a product you have bought before may have changed. For loose items such as bakes and pastries, ask for allergen information and use the official guide.†
