Jewellery retailer Pandora recorded strong sales growth in the UK during the third quarter as it posted a 33.8% rise in group EBITDA.

The jeweller said UK like-for-like sales increased 20.6% for the three months to September 30 2014.

Total UK sales surged 35.1% compared to the same period last year.

Pandora put its improved sales performance down to offering customers newness and better training of in-store staff. It said it reported increased store traffic in most stores during the quarter.

Rings proved to be a sparkling winner, with like-for-like sales of the category up 50% during the period. During the quarter more than 15% of revenue was generated by rings, indicating the shift away from purely charms and bracelets and into new growth categories. 

The retailer said it had opened 37 franchise new stores since the third quarter last year. Pandora now operates 150 stores in the UK and 1,200 globally.

Group sales jumped 26.2% to DKK 2,845m (£300m) in the third quarter. EBITDA was up 33.8% to DKK 1,020m (£107m) for the quarter.

Pandora chief executive Allan Leighton said: “We are pleased with another strong performance, with our highest revenue and EBITDA in any quarter to date.

“All regions continued to perform well, driven by expansion of the store network, improving store execution, and continuously relevant products. In addition, the result of our focus on rings is particularly pleasing, with revenue for the category almost doubling in the quarter.”
