Tuna Mayonnaise & Cucumber Sandwich sits 2nd of 16 on price in Greggs’ Sandwiches & Salads section, at £3.00 and 333 kcal. Updated 12 September 2026.
Made in tasty malted brown bread with tuna and mayonnaise. We add cucumber for a taste of crunchy freshness, then leave it at that. Nice and simple. Like all our sandwiches, our Tuna Mayonnaise and Cucumber Sandwich is freshly prepared in shops every day. Pair it with a bag of our salt and vinegar crisps for an elite meal - no matter the time of day.
The £3.00 figure came from a third party listing rather than from Greggs, 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 Greggs Tuna Mayonnaise & Cucumber Sandwich
How to order Tuna Mayonnaise & Cucumber Sandwich at Greggs
Tuna Mayonnaise & Cucumber Sandwich is available at the till, on the kiosk screens and through the Greggs app, for collection or for delivery. It is filed under Sandwiches & Salads. Availability is set per branch, so a smaller site may not carry it at all.
Greggs Tuna Mayonnaise & Cucumber Sandwich price in 2026
The Greggs Tuna Mayonnaise & Cucumber Sandwich price in 2026 is £3.00 on the figures we hold. The figure came from a third party listing rather than from Greggs, so read it as a ceiling. Within the Sandwiches & Salads section that puts it 2nd of 16 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 174 Greggs branches across 4 of the four UK nations, with the Glasgow postcode area holding the most at 27. Menus vary by site, so a listing here is national rather than a promise about your nearest one. The Greggs app confirms it in seconds.
What 333 kcal means here
333 kcal is a little below the Sandwiches & Salads 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.
Salt worth knowing about
At 1.2g of salt it accounts for 20% 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.
Where it sits on price
1 item costs less than this one in the Sandwiches & Salads section and 14 cost more, out of 16 we hold a price for. The closest thing to it on price is Tandoori Chicken Sandwich at £3.00, so those two are the real comparison when you are deciding.
Pro Tips for Ordering Tuna Mayonnaise & Cucumber 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 Greggs that is a normal counter request rather than a special one.
Protein for the calories
It gives 6.3g of protein per 100 kcal, against a menu average of 3.9g across everything we hold for Greggs. 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 21 in its section.
Allergens declared
Greggs declares 5 of the 14 allergens UK law requires to be listed for this item: cereals containing gluten, eggs, fish, mustard and soya. It also lists celery, milk and sulphites (sulphur dioxide) as a possible trace, meaning Greggs cannot rule those out. 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.
