Most quotes land between £8 and £14 per guest. Here is what sits behind that number.
Staffing
Two trained servers for up to 150 guests, three above that. Staffing is the single biggest line item.
Stock and equipment
Real tea bases, fresh fruit, properly cooked tapioca and the shakers, burners and coolers that keep them right.
Travel and branding
Travel is included in most UK quotes. Branded cups and custom signage are optional extras.
