The latest trading update from Dixons Carphone – which operates the Currys PC World and Carphone Warehouse chains – paints a mixed picture for the electrical retailer.
It said that like-for-like revenues from mobile phone sales fell by 9% in the 10 weeks to 4 January across the UK and Ireland.
Dixons has a turnaround plan, which involves improving its online offering and making its physical stores more engaging for shoppers.
It said its plan is working so far, and also pointed to some bright spots, with revenues from electricals up 2% in the same period.
The group chief executive Alex Baldock said over Christmas it sold 75% more 65″ TVs, as well as 8,000 smart speakers a day.
Overall, he said the firm was “on track to deliver what we promised for this year, and with our longer-term transformation.”
