High street health and beauty retailer Boots has recorded a rise in sales as its online performance continues to grow.

In an update by parent company Walgreens Boots Alliance (WBA), Boots UK sales grew 5% in the three months to May 31.

Its comparable retail sales increased 6% on a constant currency basis while pharmacy sales increased 5.4%.

Boots’ website continues to go from strength to strength, rising 18.7% or 14.8% on a constant currency basis.

Online sales now represent 17% of Boots total retail sales.

WBA said the company’s overall adjusted operating income rose 22% to $214m, which reflects a strong retail performance in Boots.

WBA chief executive Tim Wentworth said of the results: “We remain focused on our turnaround plan, which will require time, disciplined focus and a balanced approach to manage future cash needs with investments necessary to navigate an evolving pharmacy and retail environment.”

Following news in March that WBA will be acquired by private equity firm Sycamore Partners, the merger is now expected to be complete in the third or fourth quarter of this year depending on shareholder and regulatory approvals.
