Trollope & Colls was once one of the United Kingdom's largest construction companies.



The Company was formed in 1903, out of the merger of George Trollope & Sons (founded by Joseph Trollope, a wallpaper hanger, in 1778) and Colls & Sons (founded by Benjamin Colls, a painter and decorator, in 1840). [1]

The merged firm started to specialise in civil engineering and during the First World War undertook pioneering work on reinforced concrete. [1] In 1969 the Company was acquired by Trafalgar House. [1] By 1994 it was the largest contractor in the United Kingdom by turnover. [2]

On 18 April 1996 Norwegian shipbuilding and engineering group Kvaerner acquired Trafalgar House Construction, as the business became known, as part of a £904 million offer for Trafalgar House plc. [3]
