The price is missing here for a reason. McDonald's 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 McDonald's Double Filet-O-Fish
How to order Double Filet-O-Fish at McDonald's

McDonald's Double Filet-O-Fish price in 2026
There is no verified McDonald's Double Filet-O-Fish price for 2026. McDonald's 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.
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 453 kcal means here
453 kcal is a little below the Burgers average. That is a full meal's worth on its own, before anything else goes on the tray. 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.
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.
A lighter choice in the same section
Filet-O-Fish sits in the same part of the menu at 316 kcal, which is 137 fewer than this for £4.39. 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 Double 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.
