Guide to Vegan Fish Alternatives in 2026 (UK)

Thanks to all the amazing vegan fish substitutes out there, swapping out seafood has never been easier

Vegan Fish Alternatives UK 2026

When you first dip your toe into the world of plant-based foods, exploring vegan seafood can seem a little strange. But we promise you can still enjoy the same tastes and textures without the cruelty, ecological damage and health concerns associated with eating sealife.

Thanks to documentaries like Seaspiracy, people are more aware of intensive fish farming and fish sentience, destructive fishing practices and the plight of forgotten marine animals like sea turtles and octopuses.

With plant-based fish options popping up left, right and centre in supermarkets and restaurants, it’s hard to keep track of all the tasty alternatives to our favourite fish dishes.

From classics like fish fingers and burgers to yummy goujons and prawns, you’re bound to find an alternative to suit you. We’ve put them all together in a handy guide – you’re welcome!
