Thomas Harrington & Sons Ltd was a coachbuilder in the county of Sussex from 1897 until 1966, initially at Brighton but from 1930 until the end in a purpose built Art Deco factory (an image of which was used on the builder's transfers) at Old Shoreham Road, Hove.
The company began with the construction of horse-drawn carriages. With the rise of motor vehicle, Thomas Harrington began building on motor car chassis, and prior to World War I began to specialise in commercial vehicles, buses and coaches. After the armistice the company concentrated on luxury coaches supplementing these with some single-deck bus bodies and other general coachbuilding activity.
During World War II they were selected by the War Ministry to build a specialised aircraft design and during their history they also produced ¼ - scale street-legal model coaches to entertain children, pioneered a minibus that bus operators found practical (and legal) to use and drove-forward coach design. They had an open outlook on developments in technology and an excellent grasp of marketing opportunities and an eye for a catchy press advertisement. They nurtured relationships with customers, one at least bought nothing other than Harrington for its entire existence.
In 1965 it was decided to close the factory. Although not a part of the Rootes Group, the operations were owned by a Rootes family investment company. Production ceased in April 1966 after which Plaxton purchased spares, stock in trade and goodwill.
The Cavalier (1959–64) and Grenadier (1962-6) luxury coach bodies for underfloor-engined chassis jointly won the Classic Bus reader poll as the most stylish coach of all time. Many Harrington vehicles are preserved and Harrington devotees have a gathering of their own.
There were huge numbers of small to medium-sized professional coachbuilders in existence around Britain as Thomas Harrington & Sons Ltd moved into its new Hove factory. The management of Harringtons decided that two things were necessary to stand them in good stead in this crowded market. The first was building good relationships with blue-chip customers, and the second was to produce designs with a distinctive Harrington 'look'.
Instances of the first were their long-term supply to high–class coach firms in the private and large company sectors. Such private customers included Grey-Green of Stamford Hill, London, Charlies Cars of Bournemouth and Silver Star of Porton Down. The large firms included the Tilling Group's North Western Road Car Company of and BET-group member Devon General of Exeter, but perhaps the most enduring relationship of all was as supplier to the local BET coaching powerhouse Southdown Motor Services.
