The £7.2bn figure would be almost double the figure for 2009, as retailers continue to increase their assault on the online sector. In 2009 13% of adults shopped online for groceries, an increase of 63% on 2006.
IGD’s research also shows that the majority of consumers are disloyal when it comes to shopping with a retailer online, with 61% of online grocery shoppers use more than one online store for their food shopping.
Joanne Denney-Finch, chief executive at IGD, said: "Our research shows there is a great opportunity for grocery retailers and manufacturers to encourage shoppers to try online food shopping.
"People are increasingly mixing the channels they use for their weekly or monthly shop. Many are choosing to visit their local store on a regular basis, while purchasing a number of bulk items, like tinned foods and toiletries, online less frequently.
"The future of grocery shopping is ‘multi-channel’, with people shopping in different ways and using various outlets – whether convenience stores, online or hypermarkets."
