Sales via smartphones and tablets grew exponentially in June,leaping 356%compared to the same month last year,according to an IMRG Capgemini report.
The total online spend in the UK for June was 6bn pound,a 13%increase compared to last year.
British shoppers spent 34.9bn pound online in the first six months of 2012,compared with 31bn pound in the same period in 2011,an increase of 12.5%,found the report.
Chris Webster,head of retail consulting and technology at Capgemini said:"Mobile commerce is still the big story here,with average order values comparable to the full website,356%year-on-year growth and retailers seeing mobile sales at circa 8%of their total digital income."
The findings echo research from the British Retail Consortium(BRC),which found that mobile and tablet search volumes grew by 113%in the second quarter of 2012,compared to the same period last year.Total search volumes from overseas consumers rose by 42%in Q2 compared with the previous year,said the research.
Richard Lym,economist at the British Retail Consortium,said that while mobile searches do not translate directly into mobile sales,there is a strong correlation between the growth in both areas.
"Most retailers would agree the pace of technology is moving at a frightening pace,and they are having trouble keeping up as we move forward,"he said.
"It obvious that this is not just about online,or m-commerce but about multi-channel retailing.M-commerce in retail is growing quickly,but is coming from a small base.It is growing fast,but is a small part of the pie.
"NFC[near-field communication]is going to play a large role in shaping the future of m-commerce.A lot of phones aren't yet NFC enabled,but when they are this will change the way retailers interact with consumers,"he said.
The BRC also found that tablets account for 40%of mobile/tablet searches.According to the trade association,around a fifth of all online spending is on food and drink but only 4%of total grocery spending happens online.
"With non-food goods dominating online spending,there are huge opportunities for food retailers to expand their internet businesses and this will be a big area of competition in the coming months and years,"said Stephen Robertson,director general of the BRC.
