Crispy white Pollock fish filet patty, with cheese and tartare sauce, in a steamed bun. From an MSC certified sustainable fishery. www.msc.org
The £4.39 figure came from a third party listing rather than from McDonald's, 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 McDonald's Filet-O-Fish
How to order Filet-O-Fish at McDonald's
Counter, kiosk and app all carry it. The McDonald's app adds collection and delivery. It is filed under Burgers. Availability is set per branch, so a smaller site may not carry it at all.
McDonald's Filet-O-Fish price in 2026
The McDonald's Filet-O-Fish price in 2026 is £4.39 on the figures we hold, with branch to branch variation between £4.39 and £4.89. The figure came from a third party listing rather than from McDonald's, so read it as a ceiling. Within the Burgers section that puts it 6th of 12 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 119 McDonald's branches across 4 of the four UK nations, with the Leeds postcode area holding the most at 9. Menus vary by site, so a listing here is national rather than a promise about your nearest one. The McDonald's app confirms it in seconds.
Where it sits on price
5 items cost less than this one in the Burgers section and 6 cost more, out of 12 we hold a price for. The closest thing to it on price is McChicken Sandwich at £4.19, so those two are the real comparison when you are deciding.
Allergens declared
McDonald's declares 5 of the 14 allergens UK law requires to be listed for this item: cereals containing gluten, eggs, fish, milk and mustard. It also lists sesame as a possible trace, meaning McDonald's cannot rule that 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.
What 316 kcal means here
316 kcal is well below the Burgers 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.
Pro Tips for Ordering Filet-O-Fish
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 McDonald's rather than an awkward one.
