Domino’s Pizza has unveiled a number of changes to its operation in the UK – including the launch of its first 24-hour outlets and the introduction of a new line of sandwich subs. The initiatives mark a change of focus for the operator as it expands it offering and goes up against Subway during the day plus enters the 11pm to 2am post pub market for the first time. The group, which unveiled a 13.7% increase in like-for-like sales last month, said its outlets in Crawley, West Sussex and in All Saints in Manchester went live with 24 hour opening this week. Plus, all of its 627 stores are now offering sub style oven roasted sandwiches – with prices being set locally by franchisees – after a soft launch earlier this year at several sites. The range of subs includes a cheese steak melt, a breakfast sub and meatball sub. The company has also launched a new marketing campaign to promote the sandwiches, which have been available in the US since 2008.
