Everything You Need to Know About Costa Coffee Signature Latte
How to order Signature Latte at Costa Coffee
Signature Latte 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. Branch by branch availability varies, which the app reflects once you choose a location.
Costa Coffee Signature Latte price in 2026
There is no verified Costa Coffee Signature Latte 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.
What 150 kcal means here
150 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.
Protein for the calories
It gives 7.3g of protein per 100 kcal, against a menu average of 3.4g across everything we hold for Costa Coffee. 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 33rd of 132 in its section.
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.
A lighter choice in the same section
Apple Slices sits in the same part of the menu at 47 kcal, which is 103 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.
Pro Tips for Ordering Signature Latte
Ordering it the way you want
Size and milk are the two levers on a drink like this, and both move the calorie figure more than any syrup does. A smaller cup with semi skimmed milk lands well below the same drink made large with whole milk. Costa Coffee publishes figures for the standard build, so any change you ask for moves you off the number in the table above.
Allergens declared
Costa Coffee declares 1 of the 14 allergens UK law requires to be listed for this item: milk. 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.
Diet marking
Costa Coffee marks this as 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.
