Milk float in Earlsfield in London, England, United Kingdom. In Britain, a milk float is a vehicle specifically designed for the delivery of fresh milk. Today, milk floats are usually battery electric vehicles. They were once common in many European countries, particularly the United Kingdom, and were operated by local dairies. However, in recent years, as the number of supermarkets, small independent grocers and convenience stores stocking fresh milk has increased, many people have switched from regular home delivery to obtaining fresh milk from these other sources.
