Beechwood smoked bacon with tomato, lettuce & mayo on malted bread.
The price is missing here for a reason. Costa Coffee does not publish one we could check, and a guess dressed as a figure is worse than an honest gap.

Everything You Need to Know About Costa Coffee BLT Sandwich
How to order BLT Sandwich at Costa Coffee
BLT Sandwich 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 BLT Sandwich price in 2026
There is no verified Costa Coffee BLT Sandwich 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.
A lighter choice in the same section
Almond Croissant (V) sits in the same part of the menu at 318 kcal, which is 101 fewer than this for £3.45. That swap is the single biggest change available inside this section, and it needs no substitution or special request at the counter.
Salt worth knowing about
At 2.1g of salt it accounts for 35% 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.
Fibre
5.6g of fibre is a genuinely useful amount against the 30g a day UK adults are advised to get and mostly do not. Very little on a fast food menu contributes here, so it is worth noting when something does.
Allergens declared
Costa Coffee declares 3 of the 14 allergens UK law requires to be listed for this item: cereals containing gluten, eggs and mustard. 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 BLT Sandwich
Built to order
Items like this are assembled to a standard build, and the published figure describes that build. A swap or a dropped filling changes it, and at Costa Coffee that is a normal counter request rather than a special one.
Protein for the calories
It gives 5.0g 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 13th 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.
