Phones 4U retail like-for-like sales soared 15.8% in December following momentum built up over a strong year.

The phone specialist’s retail division recorded a total sales rise of 23.3% in December to £121.6m.

Total sales were up 20.7% in the year to December 31 while full-year like-for-like sales rose 11.9%. 

Online sales grew strongly, up 47.3% in December, and up 73.2% for the full year.

The company said the strong growth was primarily driven by contract volumes which were up 34.8% year-on-year in December and up 26.8% for the full year.

Phones 4U group chief executive Tim Whiting said: “Our impressive Christmas numbers are reflective of consistently strong performance throughout 2012 as we continue to grow market share, especially amongst customers looking for the latest high-end smartphones purchased on contracts.” 

He added: “At a time of continued economic uncertainty, it is more important than ever that we give our customers clear advice on the next generation of smartphones and technology.”
