The United Electric Car Company was a tramcar manufacturer from 1905 to 1917 in Preston, Lancashire.
The Electric Railway and Tramway Carriage Works was formed in 1897 registered on 25 April 1898 to acquire works at Preston, Lancashire. It was founded by two Scots, W. B. Dick and John Kerr.
They formed a new company, English Electrical Manufacturing based in a new West Works on Strand Road, Preston in 1900, to build the electric motors for their trams.
In 1905 the Electric Railway and Tramway Carriage Works took over two other works, including G.F. Milnes & Co. in Hadley, Shropshire, the name being then changed to United Electric Car Co.
By 1914, the company employed around 2,000 people. They produced electrical equipment for tramways and railways and built over 8,000 tramcars, for service in the UK and abroad, including to the Buenos Aires tramways operated by the Anglo-Argentine Tramways Company.
In 1917 Dick, Kerr & Co., also in Strand Road, Preston, acquired the United Electric Car Co and in 1918 the Company became a part of English Electric.
