Aug 4 (Reuters) - Domino's Pizza Group reported a 3.6% rise in first-half profit on Tuesday, helped by solid demand for its pizzas during the soccer World Cup and new products like Chick 'N' Dip.

Such new products helped offset broader constraints in consumer budgets due to the surge in energy prices driven by the Iran war.

"We have carried positive momentum into July and, with our major cost lines hedged through 2026 and into next year, remain confident in delivering our full-year expectations," CEO Nicola Frampton said a statement.

The group operates under the umbrella of U.S.-based Domino's Pizza in the UK and Ireland.

Official data last week showed British retail sales were boosted in June by the soccer World Cup, thanks to England's good run in the tournament, as fans spent on food and other things despite concerns over the cost of living.

"The earnings profile laid out looks much brighter and secure than at any time in the last five years," Panmure Liberum analyst Wayne Brown said.

Domino's shares, which have gained nearly 18% so far this year, were up about 1.8% at 207.8 pence as of 0802 GMT.

The group posted underlying EBITDA (earnings before interest, tax, depreciation and amortisation) of £66.2 million ($88.86 million) for the 26 weeks ended June, above the £63.9 million reported a year earlier.

Total system sales - a term used in the franchising industry to represent sales of all outlets that use a brand name - came to £825.3 million in the first half, up over 6% year-on-year.
