For millions of people across the UK, food allergies and dietary restrictions are a daily concern. Whether you’re allergic to gluten, dairy, eggs, nuts, or just trying to avoid certain ingredients, eating out can be stressful — especially if clear information isn’t available.
If you’re a regular customer or just visiting Greggs for the first time, you might wonder:
“What’s actually inside Greggs sandwiches?”
“Are they safe for people with allergies?”
This article is your complete 2025 guide to Greggs sandwich allergens, ingredient breakdowns, and safe eating practices — so you can confidently enjoy your meal without risking a reaction.
Why This Matters: Food Allergies in the UK
According to the NHS and Allergy UK, nearly 1 in 3 people experience some kind of food sensitivity. The most common food allergens include:
- Milk (dairy)
- Eggs
- Wheat (gluten)
- Soy
- Nuts (especially peanuts and tree nuts)
- Fish and shellfish
- Sesame
Even small traces can cause serious reactions — from skin irritation to life-threatening anaphylaxis. That’s why transparent allergen labeling is crucial.
Do Greggs Sandwiches Contain Allergens?
Yes. Most Greggs sandwiches contain at least one major allergen, especially gluten, milk, eggs, or soy. Some may also contain mustard, sesame, or sulphites.
Greggs provides a detailed allergen guide, updated regularly, but it’s not always visible in-store. You can view it on their official website or request it from a staff member.

Is Cross-Contamination a Risk at Greggs?
Yes. Greggs does not have separate preparation areas for allergen-free foods. Even if an item doesn’t contain a certain allergen, it may be exposed during storage, prep, or handling.
Greggs’ official allergen disclaimer:
“We cannot guarantee any of our products are free from allergens due to shared kitchen equipment and handling.”
So if you have a severe allergy, Greggs may not be safe, even for items that appear allergen-free on paper.
Greggs Sandwiches That Are Relatively Safer for Common Allergies
Here are a few options that may work for people with mild sensitivities (not severe allergies), based on the 2025 menu:
1. Vegan Chicken-Free Sandwich
- No dairy or egg
- Still contains gluten, soy, mustard
2. Chargrill Chicken Oval Bite
- No cheese
- Contains egg (in mayo), soy, gluten
3. Boiled Eggs or Porridge (if avoiding gluten)
- Safer side options
- Still ask staff about prep safety
Can I Order a Custom Allergen-Free Sandwich at Greggs?
No. Greggs does not currently offer custom sandwiches. All items are pre-made or pre-assembled in batches, and you can’t request substitutions (e.g., “no mayo” or “gluten-free bread”).
This limits flexibility for allergy sufferers. If you need full control over ingredients, Greggs may not be suitable.
What About Gluten-Free Options?
As of 2025, Greggs does not offer any certified gluten-free sandwiches.
- All sandwich breads (baguettes, rolls, oval bites) contain wheat flour.
- Even side items like hash browns and sausage rolls may contain gluten or be cross-contaminated.
- Greggs tested gluten-free items in the past (like GF brownies), but not sandwiches.
If you’re coeliac or gluten-sensitive, it’s safest to avoid all sandwich options.
Are Greggs Sandwiches Safe for Vegans or Dairy-Free Customers?
Vegan-Friendly Sandwich:
- Vegan Chicken-Free Sandwich
This is your only fully vegan sandwich. It’s egg-free, dairy-free, and meat-free, made with plant-based proteins and vegan mayo.
But be aware:
- Still contains gluten and soy
- Risk of cross-contact with dairy and meat in prep areas
Greggs is working to expand its vegan options, but right now, the selection is limited.

Final Advice: If You Have a Food Allergy at Greggs
- Always double-check ingredients — even for familiar items

Conclusion: Can You Eat Greggs Sandwiches with Allergies?
It depends on your allergy severity.
If you have mild intolerances or sensitivities, you can find a few options like the Vegan Chicken-Free Sandwich or simple chicken baguettes.
But if you have serious food allergies (gluten, dairy, egg, or nut), Greggs sandwiches are not prepared in allergen-safe kitchens and may pose a risk due to cross-contamination.
Greggs is transparent with its allergen info and ingredients — which helps you make safer, smarter decisions. But it’s up to each individual to evaluate the risk based on their health needs.
