Domino's Pizza has reported a 13.1% rise in sales in Ireland during the 13 weeks to September 24, which it attributed to a jump in online transactions.

The company said its Irish performance was driven by very strong growth in digital participation, with online sales up 30.9%. They now represent 58% of total sales. 

Domino's Pizza said it opened its first new store in Ireland for six years during the three month period, taking the total store count to 48.

Overall, the fast food company netted sales of £286.4m in the third quarter. It also has operations in Switzerland, Iceland, Sweden and Norway.

Domino's Pizza said that sales at its UK stores open for more than a year rose by 8.1%. UK sales were boosted by a 17.4% surge in online orders.

The company said it would open 90 stores in UK this year, citing strong demand for delivered food in the UK despite the uncertain consumer environment. 

David Wild, the company's chief executive, said he was pleased with its performance in the third quarter, especially the improved trend in its core market of the UK. 

"Additionally we are making progress in all our overseas operations. In Ireland and Switzerland, our online initiatives are fuelling accelerated growth, and in Norway the first Dolly Dimple's conversions are trading very well," Mr Wild added.

The company said it expects its full-year underlying profit before tax to meet market forecasts.
