Belgian Bun sits 13th of 21 on price in Greggs’ Sweet Treats section, at £1.75 and 374 kcal. Updated 12 September 2026.
A soft fruit bun, lemon flavoured pieces, wonderfully soaked sultanas, tangy apricot jam, topped with fondant icing… AND a cherry on top.
The £1.75 figure came from a third party listing rather than from Greggs, which means it may reflect a delivery menu. Delivery prices sit above in restaurant prices before any fee is added, so treat this as the ceiling rather than the till price.

Everything You Need to Know About Greggs Belgian Bun
How to order Belgian Bun at Greggs
You can order Belgian Bun at the counter, at a Greggs kiosk, or in the Greggs app for collection or delivery. It is filed under Sweet Treats. Availability is set per branch, so a smaller site may not carry it at all.
Greggs Belgian Bun price in 2026
The Greggs Belgian Bun price in 2026 is £1.75 on the figures we hold. The figure came from a third party listing rather than from Greggs, so read it as a ceiling. Within the Sweet Treats section that puts it 13th of 21 on price. Expect more at airport, motorway and station branches than on a high street, and more again through a delivery app.
Where it sits on price
12 items cost less than this one in the Sweet Treats section and 8 cost more, out of 21 we hold a price for. The closest thing to it on price is Star Biscuit at £1.75, so those two are the real comparison when you are deciding.
What 374 kcal means here
374 kcal is well above the Sweet Treats average. That is a normal single course for most people, and it leaves room for a side. The 2,000 kcal figure printed on UK menus is a reference intake for an average adult, not a target, and it is the number these percentages are worked against.
Allergens declared
Greggs declares 3 of the 14 allergens UK law requires to be listed for this item: cereals containing gluten, soya and sulphites (sulphur dioxide). It also lists eggs, milk and mustard as a possible trace, meaning Greggs cannot rule those out. A declaration covers the recipe and not the kitchen, and every one of these chains prepares food in shared fryers and on shared surfaces. For a severe allergy the only reliable check is asking staff on the day.
Finding it near you
We list 174 Greggs branches across 4 of the four UK nations, with the Glasgow postcode area holding the most at 27. Menus vary by site, so a listing here is national rather than a promise about your nearest one. The Greggs app confirms it in seconds.
Pro Tips for Ordering Belgian Bun
Ordering it
The figure in the table is the standard build. Anything added at the counter sits on top of it, and anything left out comes off, which is a normal request at Greggs rather than an awkward one.
Protein for the calories
It gives 1.6g of protein per 100 kcal, against a menu average of 3.9g across everything we hold for Greggs. That is a weak ratio for this menu, which matters more than the raw protein figure when you are comparing two items of different sizes. On raw protein it ranks 3rd of 24 in its section.
Sugar in plain terms
46g of sugar works out at roughly 12 teaspoons. The adult reference intake is 90g a day and the NHS free sugars guideline is tighter at 30g, so one of these covers a real portion of either figure.
