The estimate follows Kantar Worldpanel data which shoed that the market was up 6.3% in the 52 weeks to August 13.

The top three sales categories, fresh produce, dairy and grocery, are said to have driven the growth, with grocery adding a 39% increase in sales over the last four years.

Speaking at the show, Dan Rusga, marketing director at organic brand, Yeo Valley, said, “Consumer attitudes are changing, with the importance of quality products and traceability now at the forefront of producer, brand and retailer strategies."

Data from Kantar Worldpanel found that over 50% of shoppers now actively look for assurance labels on products.

“Organic isn’t a badge,” added Rusgba. “Consumers easily see through inauthenticity.

“Delivering products that continue to meet consumer needs and values, which match our own, gives us a unique opportunity to keep the organic market growing.”

The event, which focused on changing consumer and retails trends, highlighted teas, nut butters, free-from products, energy bars, fresh fruit and cereals as products at the forefront of organic growth.

London is still the largest sales region for organic with strong growth noticed in the south and south west of England, helped by young shoppers and smaller households who it was suggested were looking for “ethically” driven purchases.
