Domino's Pizza Group said it expected full-year results to be ahead of its expectations after a strong third quarter boosted by a surge in online sales. 

The group said its Irish like-for-like sales rose by 14.1% for the 13 weeks to September 27, while UK like-for-like sales were up 14.9%. 

It said it was "very encouraged" by the third quarter results in Ireland. 

It said it was also seeing an increasing trend towards digital ordering and the benefits of the continued economic recovery.

The group also operates in Switzerland and Germany. It said that while the results are encouraging, there still remains a lot to do to improve the overall performance of these businesses.

The company said it was on track to open at least 50 stores in the UK during 2015.
Domino's said there was huge demand for its mobile app and revamped website, which customers were increasingly using to order their pizza, sides and drink bundles. 

Almost 75% of delivered sales were placed online in its third quarter, with more than half of these placed through the app. 
Analysts have forecast that the company's pre-tax profit will rise by 24% over the full year, with UK like-for-like sales gaining 10.5 percent. 
The company said today it was maintaining its interim dividend at 5.67 pence per share.
