Ocado is boosting its frozen fish offerings with the launch of five The Fish Society’s premium frozen seafood products, marking the UK’s online fishmonger’s biggest retail expansion to date.

Available from 24 September 2025, the new range brings restaurant-quality frozen fish to Ocado customers nationwide – including Yellowfin Tuna, Wild Bluefin Tuna, Miso Black Cod, Swordfish Steaks and Arctic Char, all handpicked from The Fish Society’s 300-strong online range.

The move follows the brand’s growing presence in premium retail, with existing partnerships at Harrods and Abel & Cole, and forms part of its wider strategy to bring sustainable, high-quality frozen seafood to new audiences.

The online supermarket launch also reflects the category’s strong growth, with the UK frozen fish and seafood market rising at a 4.15% between 2018 and 2023, according to figures from GlobalData.

“Right now, the Frozen category is having its moment, and we’ve seen exciting outperformance at Ocado over the last 12-18 months,” said Ocado frozen senior buyer Zee Ahmad.

“In addition, Ocado is on a mission to bring more newness to our shoppers, particularly where we can partner with emerging challenger brands, supported by our Ocado Roots program.”

“The Fish Society launch is a great example of the accessibility and premium quality frozen foods can offer, and we are very excited to introduce these new species to our shoppers.”

The Fish Society CEO Jeremy Grieve added: “We at The Fish Society are very thrilled to launch our beautiful range of fish into Ocado.

“Until now, the majority of our successes have come from our D2C platform/website but as we observe the opportunity for a strong premium fish brand in this category, we have recently grown into retail with Harrods and Abel & Cole.

“The launch of our range into Ocado is our biggest yet. We would love to thank the co-operation of the amazing team at Ocado to make our brand available to their Ocado shoppers.”
