No verifiable price exists for it. Costa Coffee sets prices branch by branch and publishes no national list, so the only accurate number is the one on the board in front of you or in the app.
Allergens Costa Coffee declares
None of the 14 regulated allergens is listed as an ingredient.

Everything You Need to Know About Costa Coffee Watermelon
How to order Watermelon at Costa Coffee
Watermelon is available at the till, on the kiosk screens and through the Costa Coffee app, for collection or for delivery. It is filed under Our menu. Availability is set per branch, so a smaller site may not carry it at all.
Costa Coffee Watermelon price in 2026
There is no verified Costa Coffee Watermelon price for 2026. Costa Coffee 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.
Diet marking
Costa Coffee marks this as vegan and vegetarian. That is the chain's own classification of the recipe rather than a statement about how it is cooked, and vegan marking in particular sits alongside shared equipment at most of these brands.
Finding it near you
We list 2,561 Costa Coffee branches across 3 of the four UK nations, with the Birmingham postcode area holding the most at 72. Menus vary by site, so a listing here is national rather than a promise about your nearest one. The Costa Coffee app confirms it in seconds.
Protein for the calories
It gives 2.3g of protein per 100 kcal, against a menu average of 3.4g across everything we hold for Costa Coffee. 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 113th of 132 in its section.
Allergens declared
Costa Coffee lists none of the 14 allergens UK law regulates as an ingredient of this item. 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 Watermelon
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 Costa Coffee rather than an awkward one.
What 66 kcal means here
66 kcal is well below the Our menu average. On its own it is a small addition to a day rather than a meal. 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.
