Online retail sales in the UK rose by 16% in 2013 to £91bn, with an 18% growth achieved in December with the rise in online spending to £11bn, a new report revealed.
According to the latest IMRG Capgemini e-Retail Sales Index, e-retail is anticipated to account for 21% of the overall retail market.
The rise in m-retail has boosted the sales via smartphones and tablets by 138% during the year, and 27% of all online sales during December were done through a mobile device, which is double the amount spent during the corresponding period in 2012.
IMRG chief information officer Tina Spooner said with online shopping having become part of everyday lives, the growth levels that is being seen in the e-retail market won't be slowing down any time soon.
"We predict that the UK online retail market will achieve 17% year-on-year growth during 2014 and we also expect the £100 billion threshold will be broken, with a staggering £107 billion predicted to be spent online in the UK alone this year," Spooner said.
"Shopping has become a leisurely activity for many of us and mobile devices have fundamentally altered the way that consumers engage with brands.
"Often we browse on our smartphones during our morning commute and 'sofa surf' in the evenings on our tablet devices.
"With mobile and tablets now accounting for almost 4 in 10 visits to e-retail websites and 27% of the UK online retail market, we expect growth to continue throughout 2014 with m-retail set to account for 30% of online sales during Q1."
The report also added that about 80% of mobile sales were made via tablets, while sales via smartphones are rapidly rising as retailers fine-tune their websites to facilitate shopping via a phone.
Capgemini retail and technology head Chris Webster said for the first time in three years there has been a year-on-year rate of growth of e-retail, accelerating from 14% in 2012 to 16% in 2013.
"This performance has been fuelled by a variety of factors, not least the huge leaps in mobile technology, which has given a whole new section of society access to the internet and enabled the more tech savvy amongst us to shop while on the move," Webster said.
"Combined with greater choice of delivery and collection options, as well as improved retail trading, the e-retail sector has all the ingredients for ongoing success."
