Asos sales skyrocketed in the first four months of its financial year, bolstered by growing momentum in its UK division.

The fashion etailer posted a 30% year-on-year jump in revenue to £808.4m in the 20 weeks to December 31.

Its performance was spurred by a 23% rise in UK sales to £300.9m.

The online retailer’s international division also delivered, with sales up 24% in the US, 42% in Europe and 34% across the rest of the world.

Asos’ number of active customers advanced 19% during the period, while its average basket size increased 3% and order frequency rose 8%.

The total number of orders placed with the fashion etailer went up 30% to 20.2 million during the period and its gross margin rose 80 basis points.

Its profit expectations were unchanged by its stellar fourth-quarter performance, but it warned that its capital expenditure would be at the upper end of expectations at approximately £220m.

Continued velocity

Chief executive Nick Beighton said: “Velocity in our technology programmes continued, with a record number of releases. Our customer proposition was further enhanced in the UK with the launch of Try Before You Buy and ASOS Instant, our same-day delivery proposition.

“Following this strong start to the year, we remain confident in our full-year guidance and delivery of our planned investments in infrastructure to support our global ambitions.”
