Starbucks UK is carrying out a trial of putting calories on menus as part of the “Responsibility Deal” struck with the Government by leading operators in March this year.

The chain is understood to have put up calorie boards in 20 of its 717 sites in the UK, and will to roll the boards out to all of them if the trial is a success.

Over 170 companies and organisations signed up to the Government’s “Responsibility Deal” earlier this year, including leading operators from the pub and restaurant sectors.

The voluntary responsibility deal aims to promote calorie labelling on menus, provide alcohol unit information on drinks, and reduce salt and remove trans fats from food items.

Pub and restaurant operators, including Enterprise Inns, Greene King, Harvester, JD Wetherspoon, Mitchell & Butlers, Punch, Whitbread, Pizza Express, The Real Greek, and YO! Sushi, signed up to the voluntary agreement.

Subway, Pizza Hut, KFC, Costa and Pret A Manger have also pledged their support.

McDonald’s announced it would introduce calorie information on its menu boards as part of the agreement. As of this September, all 1,200 of McDonald’s UK restaurants will display the calorie content of all menu items displayed on menu boards.
