The Soil Association expects the organic market to exceed £2bn with a boost from its Organic September campaign.
Growth of organic sales through supermarkets in the 52 weeks to June 18 increased over five per cent, according to Nielsen data.
Growth continued through the first half of 2016 and is now 5.2 per cent compared to 3.2 per cent at the end of 2015, against a decline of 0.9 per cent in non-organic sales for same period.
Clare McDermott, business development director at Soil Association Certification said: “Despite an uncertain market following Brexit, Soil Association Certification is positive about the future of organic and we expect this year’s Organic September to have an even bigger impact than before.
"Market growth is already strong and there’s a clear demand for organic, environmentally friendly and sustainable purchasing with many young professionals.

Produce remains buoyant and canned and packaged are strong, driven in part by cereals and tea. But organic meat is the star performer, with beef sales increasing significantly since Newcastle University published research into nutrition in organic meat and milk in February.
Organic customers continue to seek out products away from supermarkets. Independent shopping is still rising - up 7.5 per cent - and online and box scheme sales rose by 9.1 per cent. Soil Association Certification also reported increased interest in conversion to organic farming in the last year.
