In British English, a milk float is a vehicle specifically designed for the delivery of fresh milk. Today, milk floats are usually battery electric vehicles (BEV), but they were formerly horse-drawn. 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 petrol stations stocking fresh milk has increased, most people have switched from regular home delivery to obtaining fresh milk from these other sources.
Because of the relatively small power output from its electric motor, a milk float travels fairly slowly, usually around 10 to 16 miles per hour (16 to 26 km/h) although some have been modified to do up to 80 mph (130 km/h). Operators often exit their vehicle before they have completely stopped to speed up deliveries; milk floats generally have sliding doors that can be left open when moving, or may have no doors at all. They are very quiet, suiting operations in residential areas during the early hours of the morning or during the night.
In August 1967 the UK Electric Vehicle Association put out a press release stating that Britain had more battery-electric vehicles on its roads than the rest of the world put together It is not clear what research the association had undertaken into the electric vehicle populations of other countries, but closer inspection disclosed that almost all of the battery driven vehicles licensed for UK road use were milk floats.
Glasgow has one of the largest working milk float fleets in the UK. Most of the vehicles operate from the Grandtully Depot in Kelvindale. Some dairies in the UK, including Dairy Crest, have had to modernise and have replaced their electric milk floats with petrol or diesel fuel-powered vehicles to speed up deliveries and thus increase profit.
Manufacturers of milk floats in Britain in the 20th century included Morrison-Electricar, Smith's, Wales & Edwards, Osborne, Harbilt, Brush, Bedford and British Leyland. In 1941 Morrison-Electricar standardised three types of body which would become the basis for thousands of milk floats built after the war to deliver goods to the recovering population. As of 2009, only Bluebird Automotive remain in the industry.
