According to the latest Capgemini figures, UK online retail sales over smartphones and tablets are exploding.

The most recent figures from a study released by Capgemini are showing that online sales struck the £6.8 billion mark, as mobile commerce has taken off in the United Kingdom by 133 percent in August when compared to the same month in 2012.

This included shopping that was conducted over both smartphones and tablets by U.K. consumers.

The figures were calculated as a combined effort between Capgemini and IMRG. They also determined that within that month, overall online sales – including those originating from mobile commerce channels – increased by 18 percent, when compared to the same time last year.

This increase is double what was seen when online and mobile commerce sales from July 2013 were compared with 2012.

According to the Capgemini retail consulting and technology head, Chris Webster, the increase in mobile commerce sales from £674 million to £1.5 billion is the result of a number of different factors that have occurred over the last 12 months. He stated that “Firstly, the adoption of tablets and smartphones in general is rising all the time and this means sales are rising. Secondly, people are more confident using devices like this to make purchases, especially tablets.”

He also added that companies are now beginning to make their websites compatible with mobile commerce, by creating a shopping experience that has been optimized for the smaller screen and the touchscreen navigation experience. “Rather than trying to reskim their desktop site they are offering an improved customer journey.”

The increase in sales also upped the average shopping cart price. Between July and August, the average total at checkout rose from £72 to £77. Webster attributed this to a strengthening economy and that people are starting to have greater confidence in buying bigger ticket items and making higher end retail purchases.
