Earnings at quintessentially British fashion and homewares specialist Cath Kidston surged last year, powered by higher sales at home and abroad.

The retailer, which is backed by private equity firm TA Associates, posted EBITDA up by 13% to £19m.

Group revenues climbed 30% to £89m and network sales – which include the estimated retail sales of overseas partners – advanced 37% to £104m.

UK sales climbed 37% and international revenues rocketed by 61% in the year to April 1, 2012.

Cath Kidston chief executive Kenny Wilson said: “This has been a year of significant transition for the Cath Kidston group during which we have invested in the business, strengthened the management team and continued to grow the brand globally.

“We have improved our business processes including product availability and supply chain, to allow us to further expand in the UK and overseas.

“Demand for our products remains strong and, in spite of a difficult retail climate, we look forward to the future with confidence.”

The retailer increased store numbers over the year by 33 to 85 – 50 in the UK and 35 overseas.
