Everything You Need to Know About Burger King Single Stacker
How to order Single Stacker at Burger King
You can order Single Stacker at the counter, at a Burger King kiosk, or in the Burger King app for collection or delivery. Branch by branch availability varies, which the app reflects once you choose a location.
Burger King Single Stacker price in 2026
There is no verified Burger King Single Stacker price for 2026. Burger King prices per branch and publishes no national list for it, so the accurate figure is the one your own branch shows in 2026. Any site quoting a single exact national price for this item is guessing, and we would rather show the gap.
Protein for the calories
It gives 4.8g of protein per 100 kcal, against a menu average of 3.7g across everything we hold for Burger King. That is a strong 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 53rd of 134 in its section.
What 362 kcal means here
362 kcal is a little below the Menu 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.
Finding it near you
We list 584 Burger King branches across 4 of the four UK nations, with the Northern Ireland postcode area holding the most at 25. Menus vary by site, so a listing here is national rather than a promise about your nearest one. The Burger King app confirms it in seconds.
Allergens declared
Burger King declares 7 of the 14 allergens UK law requires to be listed for this item: celery, cereals containing gluten, eggs, milk, mustard, sesame and soya. 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.
Pro Tips for Ordering Single Stacker
Ordering it at the counter
Ask for it without one element, or without a sauce, and the total drops below the published figure. Staff handle that request routinely. The number in the table is the standard build as Burger King makes it. The item on its own rather than as a meal is the larger saving on both price and energy.
Salt worth knowing about
At 1.53g of salt it accounts for 26% of the 6g daily maximum the NHS recommends for adults, a noticeable share of a day in one item. Salt in restaurant food is fixed in the recipe, so the only control you have is what else goes alongside it.
A lighter choice in the same section
fsLarge Coca-Cola sits in the same part of the menu at 262 kcal, which is 100 fewer than this. That swap is the single biggest change available inside this section, and it needs no substitution or special request at the counter.
