March 10 (Reuters) - Britain's Domino's Pizza Group DOM.L on Tuesday reported a 15% fall in annual profit for 2025, hurt by muted demand, weak sales and high costs.

The company, which operates under the umbrella of U.S.-based Domino's Pizza DPZ.O in the UK and Ireland, is the latest UK restaurant operator to flag pressure from weaker consumer spending and higher employment costs.

Britons have been reining in discretionary spending amid elevated inflation, with the industry digesting sharp increases in national insurance contributions.

The pizza chain has struggled to establish a strategy to win investor confidence back and revive sales, with multiple senior executives, including its CEO and finance chief, leaving the company last year.

Domino's UK posted 91.2 million pounds ($122.65 million) in underlying pretax profit for the year ended December 28, below the 107.3 million pounds posted a year ago.

However, underlying core profit for the current year is on track to meet market expectations as its strong Christmas trading momentum carried into the first nine weeks of 2026, according to the firm.
