Nothing beats a proper fish sandwich made with the catch of the day. While many fast food places use frozen fish fingers, some UK chains take pride in serving sandwiches with fish straight from British waters.
These spots go the extra nautical mile to ensure you're getting the real deal – fish that was swimming in the sea not long before it landed on your plate.
Pret A Manger's Sustainable Catch

Pret's commitment to ocean-friendly fish makes their salmon sarnie stand out from the crowd. They source Atlantic salmon from carefully monitored Scottish farms, with each fillet prepared fresh daily in their kitchens.
The fish is paired with cucumber, rocket, and a lemon mayo that brings a zing without overpowering the delicate flavour. Pop in before 11am for the best selection – they often sell out!
Leon's Wild White Fish Wraps

Leon has made waves with their commitment to responsibly sourced white fish. Their fish finger wrap features MSC-certified cod or haddock caught off British shores, then lightly breaded in-house rather than using factory-made fingers.
The combination of crispy fish, minty mushy peas and homemade tartare sauce creates a proper chippy tea experience in portable form. A squeeze of lemon brings it all together brilliantly.
Itsu's Ocean-Fresh Sushi Sandwiches

Not your typical sarnie, but Itsu's sushi sandwiches deserve recognition. Their fish arrives daily from sustainable sources, with salmon coming from pristine Scottish waters and tuna line-caught to reduce bycatch.
The rice 'bread' is pressed fresh each morning, giving these handheld treats their signature bounce. A far cry from supermarket sushi that's been sitting around for days, these beauties maintain that just-caught taste.
EAT.'s Seasonal Fish Selection

Before being gobbled up by Pret, EAT. built a reputation for their rotating fish sandwich menu that changed with what was abundant in British waters. Their kitchen teams worked directly with day boats to secure the freshest catch.
The hot smoked salmon sandwich became legendary among London office workers. The fish was smoked in-house over oak chips, giving it a depth of flavour that mass-produced alternatives simply can't match.
Morrisons Café's Harbour-to-Table Fish Finger Sandwich

Surprising many, Morrisons Café has become a dark horse in the fresh fish game. As one of the few supermarkets with their own fishing fleets, they've leveraged this advantage brilliantly in their cafés.
Their fish finger sandwich features chunky pieces of cod or haddock landed at British ports, then breaded and fried to order. Served on a proper floury bap with mushy peas on the side, it's proper comfort food at bargain prices.
Gail's Bakery Smoked Mackerel Sandwich

Gail's has quietly built a cult following for their smoked mackerel sandwich. This oily fish is caught from small day boats operating in the North Sea, then hot-smoked over beechwood the same day.
The richness of the mackerel is balanced by pickled beetroot and horseradish mayo, all nestled between slices of their famous sourdough. It's only available certain days of the week because they refuse to use frozen fish.
Costa Coffee's Surprise Contender

Few expect great fish sarnies from a coffee chain, but Costa's salmon and cream cheese offering has earned unexpected praise. They've partnered with small Scottish smokehouses that deliver fish to stores within 24 hours of smoking.
The mild oak smoke doesn't overpower the delicate salmon, while the addition of cucumber and fresh dill brings brightness. Unlike many chains that pre-make sandwiches days ahead, Costa prepares theirs in smaller batches throughout the day.
Greggs' Local Catch Baguettes

The beloved bakery chain might be famous for sausage rolls, but their fish offering deserves attention too. Greggs works with regional suppliers, meaning their fish sandwiches in coastal stores often feature catch from nearby ports.
Their tuna crunch baguette uses line-caught fish rather than net-caught, reducing environmental impact. In Scottish stores, they even offer a special salmon and egg sandwich that uses fish from Highland farms. It's proper local eating on a budget.
