To the people from the UK, london, i would love to start my own mobile tea/coffee business on a bicycle. I don’t want to sell any food, only drinks. The question is, do i need any hygiene certificates or anything? I’ve been looking it up and i know that i will need permits for selling. But i can’t find anything on just hot drinks. Obviously i will be having milk with me but i found a great mobile bike vendor that has a built in water tank and fridge.
