Bolton-based AO World saw revenues from its website grow by 35% in the last quarter of 2015.
The retailer attributed some of its strong results to its performance over the Black Friday weekend. Overall UK revenue increased by 24%.
It also said it was researching other product categories and was continuing to build its presence in the audio visual and small domestic appliance category.
AO’s German website has now been live for over a year, with a launch in the Netherlands still on track for the spring.
In December, the company’s annualised revenue grew to €77m (around £57.7m), up by €16m (£12m) since September.
Steve Caunce, chief operating officer, said: “AO World continues to make progress on its long term plan; delivering sales growth across all categories and more customers enjoyed our excellent proposition.
“In Germany we made further progress and are proud of how our culture has translated and thank the German team for continuing to delight customers with the ao.de experience.
“Looking ahead, we remain confident that we will deliver for the benefit of both our customers and our investors and remain on track to deliver our long term strategy.”
