Like-for-like revenue in the UK & Ireland ticked up 3%. Currys said "robust" sales were driven by market share gains, with double-digit growth in new categories and B2B.
It pointed to strong sales in gaming, AI computing, large appliances, coffee machines and cooling products, offset by declines in TVs, tablets and air fryers.
Meanwhile, Nordics LFL revenue was 2% higher during the period, driven by AI computing and success in new categories such as robotic lawnmowers and vacuums.
Currys also announced the immediate launch of a new £50m share buyback programme.
Chief executive Alex Baldock said: "It's been a good start to the year, with encouraging performance across the group. In the UK&I we're pleased with the trajectory in our growth areas of new categories, B2B and the Services that are so valuable to customers and to Currys. Credit was notably strong, and iD Mobile is on track to beat the 2.5m subscriber target we set for this year.
"Our Nordics recovery continues to pick up pace. We continue to grow, improve margins and control costs well. We're confident that profit margins will step forward again this year."
