Demand for TVs, gaming sets and smart technology helped Dixons Carphone to report flat underlying revenue over the tough Christmas period, keeping it on track to meet its financial targets.
The group had reiterated the financial guidance given at its interim results last month.
It said today that growth in UK electricals and its international division had been offset by continuing declines in mobile phone sales in its home market.
Alex Baldock, chief executive since April 2018, is leading a programme to turn around Dixons Carphone.
The company has been hit by a shift in the mobile phone market as customers keep their handsets for longer, choose cheaper SIM-only deals, and turn to more flexible credit-based offers.
His plan is to focus on the group's core electricals business while revitalising its mobile phones operation. He also wants to bring the retailer's stores and online businesses closer together and develop its credit business.
Dixons Carphone trades as Currys, PC World and Carphone Warehouse in Ireland and the UK.
It said like-for-like sales in the UK & Ireland electricals division rose 2% in the 10 weeks to January 4, with strength in TVs, gaming, smart tech and small domestic appliances. The firm said it won share in a market down 3% year-on-year.
The group's international business - the Nordics and Greece - saw like-for-like sales rise 3%.
However, sales in the UK & Ireland mobile business on the same basis fell 9%, which the group said was in line with expectations.
Group like-for-like sales growth was zero. That compared to analysts' average forecast of a 1% fall and a 2% fall in the second quarter.
"We've had a good peak in a weak UK market and we're on track to deliver what we promised for this year, and with our longer-term transformation," said Baldock.
