Dennis Brothers Limited was an English manufacturer of commercial vehicles based in Guildford. It is best remembered as a manufacturer of buses, fire engines and lorries (trucks) and municipal vehicles such as dustcarts. All vehicles were made to order to the customer's requirements and more strongly built than mass production equivalents. For most of the 20th century Dennis Brothers was Guildford's main employer.
Following a decade of financial difficulties original shareholders sold out in 1972 and Dennis's ownership has since passed through quite a number of hands. The Woodbridge site was sold and a new small factory built in Slyfield remains in use by lineal business descendant, bus-maker Alexander Dennis. No Dennis haulage trucks have been built since 1985. The last Dennis fire engine left the Guildford factory in 2007.
The Dennis brand is still used on Alexander Dennis buses and Dennis Eagle dustcarts.
Dennis Brothers was founded in 1895 by brothers John Cawsey Dennis (1871–1939) and (Herbert) Raymond Dennis (1878–1939) who made Speed King bicycles. They built the bicycles, initially from bought-in parts, and sold them from their shop, The Universal Athletic Stores, in High Street, Guildford. They made their first motor vehicle in 1898, and in 1899, their first car, The Dennis Light Doctor's Car. Though shown at the National Cycle Show this car was never put into production.
