The price is missing here for a reason. Burger King does not publish one we could check, and a guess dressed as a figure is worse than an honest gap.
Allergens Burger King declares
Shared kitchens mean cross-contamination is possible. Ask in the restaurant if an allergy is severe.

Everything You Need to Know About Burger King Bacon King
How to order Bacon King at Burger King
Bacon King is available at the till, on the kiosk screens and through the Burger King app, for collection or for delivery. Not every branch stocks it, and the app is honest about that before you pay.
Burger King Bacon King price in 2026
There is no verified Burger King Bacon King 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.
Salt worth knowing about
At 3.16g of salt it accounts for 53% of the 6g daily maximum the NHS recommends for adults, a large part 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.
What 545 kcal means here
545 kcal is a little above the Menu average. That is a full meal's worth on its own, before anything else goes on the tray. 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
Burger King declares 6 of the 14 allergens UK law requires to be listed for this item: celery, cereals containing gluten, eggs, milk, 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.
Protein for the calories
It gives 5.3g 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 35th of 134 in its section.
Pro Tips for Ordering Bacon King
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 Burger King rather than an awkward one.
A lighter choice in the same section
Peppercorn Angus sits in the same part of the menu at 441 kcal, which is 104 fewer than this for £10.99. That swap is the single biggest change available inside this section, and it needs no substitution or special request at the counter.
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.
