The Saucy Fish Co is the first ever fish business that has been included into the CoolBrands list, which has been in operation for 12 years.
Apple got the top vote as coolest brand in Britain, followed by Aston Martin, Rolex and Glastonbury.
The Saucy Fish Co was a qualifying winner outside the top 20, alongside Porsche, Beats by Dr Dre and Alexander Wang fashion.
The Saucy Fish Co was started in 2010 by owners Seachill with the goal of encouraging customers to eat more fish. The colourful packaging and easy to cook ‘bake in a bag' ideas have proven popular.
Kitguru says: The company are said to hit £35 million in sales this year with a launch planned for America next month.
