Updated 12 September 2026 · price from a third party listing
Whopper Jr. sits 15th of 38 on price in Burger King’s Menu section, at £5.74 and 314 kcal. Updated 12 September 2026.
The £5.74 figure came from a third party listing rather than from Burger King, 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.
Allergens Burger King declares
Shared kitchens mean cross-contamination is possible. Ask in the restaurant if an allergy is severe.

Counter, kiosk and app all carry it. The Burger King app adds collection and delivery. Branch by branch availability varies, which the app reflects once you choose a location.
Burger King Whopper Jr. price in 2026
The Burger King Whopper Jr. price in 2026 is £5.74 on the figures we hold. The figure came from a third party listing rather than from Burger King, so read it as a ceiling. Within the Menu section that puts it 15th of 38 on price. Expect more at airport, motorway and station branches than on a high street, and more again through a delivery app.
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.
Where it sits on price
14 items cost less than this one in the Menu section and 23 cost more, out of 38 we hold a price for. The closest thing to it on price is Peppercorn Loaded King Fries at £5.79, so those two are the real comparison when you are deciding.
What 314 kcal means here
314 kcal is well 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.
Allergens declared
Burger King declares 3 of the 14 allergens UK law requires to be listed for this item: cereals containing gluten, eggs 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 Whopper Jr.
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.
Protein for the calories
It gives 4.1g of protein per 100 kcal, against a menu average of 3.7g across everything we hold for Burger King. That is a little better than the menu average, which matters more than the raw protein figure when you are comparing two items of different sizes. On raw protein it ranks 63rd of 134 in its section.
A lighter choice in the same section
6 piece Chicken Fries* sits in the same part of the menu at 214 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.
