The money raised by the levy will go to the Children’s Health Fund, launched by celebrity chef Jamie Oliver and food charity Sustain last August to support schemes that improve children’s health.
Gloria Davies-Coates, Children’s Health Fund manager, said: “We're thrilled that City Hall have chosen to partner with us. The Children’s Health Fund has been set up to raise awareness of the impact that sugary drinks have on our children’s health and to make sure the money raised from the sugary drinks levy will make a difference to children across the UK.
“Getting the Mayor of London on board sends out a very strong message to other businesses and institutions to come on board and take action on sugar.”
City Hall, the home of the Mayor of London and the London Assembly, is the first Government building in the country to introduce such a scheme. By signing up, the City Hall café, operated by OCS, is joining 130 others around the UK, including all Jamie Oliver restaurants, Leon, Abokado and Tortilla who have already introduced a levy on added-sugar drinks.
The news comes as David Cameron has now revealed he is not ruling out introducing a sugar tax as the government readies the release of its obesity strategy.
