New study reveals which UK supermarkets have seen the highest increase in salmon prices, as salmon costs rise by 4.21% on average.

After a tax was levied against Norwegian salmon exports on March 28 2023, salmon prices across UK supermarkets have increased. 

Now Money.co.uk Savings have revealed which UK supermarkets have seen the biggest increase in salmon prices, by analysing price data from Trolley on the dates March and May 23rd. 

Supermarkets with the biggest increases in salmon prices

M&S has seen the largest increase in its salmon prices since March at 14%, and is the only supermarket who have seen their prices increase by over 10%. M&S's 2 Skin On Scottish Salmon Fillets rose from £5.00 in March to £5.70 as of May, a 14% increase. 

Asda has seen the second largest increase in prices at 9.09%. Asda's 2 Flavoursome Salmon Fillets cost just £4.40 back in March, but have risen to £4.80 2 months later. 

The supermarket seeing the third highest increase is Sainsbury's, with their salmon fillets increasing by 5.88%. Sainsbury's offers 240g of Skin on ASC Scottish Salmon Fillets for £4.50 today, having risen in price from £4.25 back in March.

1. Waitrose - 0.00% change in price
2. Iceland - 0.00% change in price
3. Morrisons - 0.00% change in price

Waitrose, Iceland, and Morrison's have been seemingly unaffected by the increase in salmon prices. These chains have seen 0% changes in the price of their salmon fillets since March, however, Morrison's Market Street 2 Salmon Fillets were 24p cheaper at the end of February. 

Lucinda O'Brien, personal finance expert at money.co.uk savings said: "Norway is the world's biggest producer of farmed salmon. The Norwegian government's recent 35% tax on the fish farming industry was designed to share the profits from those with privileged access to the country's natural resources. 

"However, the consequence of this tax was not only the fall of fish farming stock prices, but financial experts predicted that here in the UK salmon prices would increase by around 10%. Our analysis has revealed that, on average, salmon prices have increased by 4.21% across 8 of the UK's leading supermarkets, with one store recording an increase of 14%.

"This comes at a time when the UK is struggling with a cost of living crisis and heavy inflation. Many shoppers are already looking to cut items from their trolleys and salmon might be the next off the list. 

"Some useful tips for those looking to reduce their grocery bills include cutting out non-essentials, such as treats and magazines, and hunting for the cheapest deals - online tools like Trolley are great for comparing prices across supermarkets. You can also try swapping all your main products to a cheaper brand to see if you can tell the difference - if you can't, stick with the cheaper one."
