The £3.69 figure came from a third party listing rather than from Costa Coffee, 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.

Everything You Need to Know About Costa Coffee Free Range Egg Mayo Sandwich
How to order Free Range Egg Mayo Sandwich at Costa Coffee
Free Range Egg Mayo 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. Not every branch stocks it, and the app is honest about that before you pay.
Costa Coffee Free Range Egg Mayo Sandwich price in 2026
The Costa Coffee Free Range Egg Mayo Sandwich price in 2026 is £3.69 on the figures we hold. The figure came from a third party listing rather than from Costa Coffee, so read it as a ceiling. Within the Our menu section that puts it 34th of 98 on price. Expect more at airport, motorway and station branches than on a high street, and more again through a delivery app.
Protein for the calories
It gives 3.8g of protein per 100 kcal, against a menu average of 3.4g across everything we hold for Costa Coffee. 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 24th of 132 in its section.
More protein for similar money
Tuna Melt Panini costs about the same at £4.30–£6.10 and carries 26g of protein against this item's 15g. If the point of the order is to be full for longer, that is the better buy of the two.
Where it sits on price
33 items cost less than this one in the Our menu section and 64 cost more, out of 98 we hold a price for. The closest thing to it on price is Pure Chamomile Infusion at £3.70, so those two are the real comparison when you are deciding.
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.
Pro Tips for Ordering Free Range Egg Mayo 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.
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.
A lighter choice in the same section
Pain Au Chocolat sits in the same part of the menu at 299 kcal, which is 101 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.
