Trollope & Colls was a British construction company. In the latter decades of the 20th century, it was one of the nation's largest construction companies.
The firm was created in 1903 from the merger of George Trollope & Sons and Colls & Sons, two established construction companies. During the First World War, Trollope & Colls undertook pioneering work on reinforced concrete. During the interwar period, it sought out work internationally in places such as the Far East. The firm was heavily involved in the reconstruction efforts following the Second World War. It was acquired by the British conglomerate Trafalgar House in 1969.
During the early 1990s, the company was reorganised, its two main arms being merged, its management centered around new headquarters, and it was rebranded as Trafalgar House Construction. On 18 April 1996, the Norwegian shipbuilding and engineering group Kvaerner acquired Trafalgar House and its subsidiaries, after which the company traded under the name Kvaerner Trollope & Colls. Throughout its existence, it was responsible for numerous major works, such as the Ministry of Defence Main Building, Trawsfynndd power station, and Hull Royal Infirmary. The firm also played a key role in expansion and restoration efforts on countless projects.
