British consumers are set to spend £19.3 billion a year using their mobile phones and tablets in ten years’ time, according to new research by Barclays Corporate.

That’s almost 5% of all retail sales - and almost 15 times higher than this year’s estimated mobile-based sales figure of £1.3 billion.

Sales through mobile devices now account for more than 10% of all purchases on eBay UK. The company says more people in the UK buy and sell goods via mobile on eBay than in any other European country.

On average, it means that one item is sold via eBay UK’s mobile platforms every second.

76% of UK high street retailers don’t have a mobile website or mobile-optimised content, according to a YouGov survey commissioned by mobile marketing and business solutions company 2ergo.

And even mobile-ready retailers are poorly prepared, with almost 20% lacking m-commerce capabilities and many others choosing to focus on iPhone users.

Online research company comScore has published the latest figures from its comScore MobiLens service.

It shows that 5.8% of mobile subscribers in France, Germany, Italy, Spain and the UK - a total of 13.5 million people - have accessed online retail sites recently. That's an overall 80% increase from 2010.
