Domino’s has been boosted by its UK sales, but warned over a high cost base in its Norwegian business.
The pizza group reported sales of £616.6 million for the 26 weeks ended up 12.8% from the comparable period in 2017.
Its profit before tax fell 9.7% during the period to £41.7 million.
Domino’s said its growth had been driven by the UK market, with sales rising 8.1% from £522.7 million to £565.1 million.
The group’s franchisees opened 22 new stores in the first half of the year, bringing its total outlets in the UK to 1,067.
Domino’s said it expects around 60 openings in the UK this year.
The pizza brand has also been building its presence in Switzerland, Iceland, Norway and Sweden.
