The shop was chosen from a list of 10 finalists, with each assessed on a wide variety of judging criteria including product quality, sustainable sourcing policies, marketing initiatives and customer service.
Paul Williams, chief executive of Seafish, said the competition for this year’s award was tougher than ever, but the Scottish shop stood out throughout the judging process.
“Their passion and determination has to be admired. I would like to offer my warmest congratulations and wish them the best success in the future,” he said.
Valerie Johnson, owner of Frankie’s Fish & Chips, said: “We now get to go home to Shetland and say that our fish and chips are the best in Scotland, England, Northern Ireland and Wales - without exception. How amazing is that. This is the highlight of my working life. I can’t thank Seafish and my brilliant team enough. You’re a credit to the seafood industry. 2015 is Frankie’s year.”
