Welcome to Costain’s Investors centre

Company history

Costain has a distinct pedigree which dates back to 1865 when Richard Costain - a 26 year old jobbing builder from the Isle of Man with vision - founded the original construction business in Liverpool. For 140 years Costain has been at the forefront of UK and international construction and was floated as a public company in 1933 with a share capital of £600,000.
Costain's achievements have shaped the landscapes across the globe. For example, in the mid 1920s, Costain built houses throughout south east England - 1,000 houses were built in Selsdon alone - for £425 each. Furthermore, in 1935, Costain built eleven miles of the Trans-Iranian Railway, seven tunnels and two viaducts in isolated mountainous terrain - a feat for which it got paid just £1 million. Also in the 1930s, Costain owned, developed and built Dolphin Square -then the largest block of flats in Europe and also built Lambeth Bridge House, as the headquarters for the Ministry of Works, which was the largest office block in Europe at that time.
The company has operated continuously in the Middle East since 1935, and in central and southern Africa since 1947. In Asia, it built the 210mw power station for Sri Lanka's Victoria Dam and hydro-electric scheme - at the time, this was Britain's largest overseas aid project. Costain played an active role in the war effort of the 1940s, with wartime work including 26 aerodromes, part of the Mulberry Harbours, munitions factories and 15,000 post-war prefabricated Airey houses.
The company expanded rapidly in the 1960s and into the 1970s through its successful presence in the Middle East; and during the same period steadily diversified into coal-mining and property in the key markets of the UK, Australia and US.
The decade began well, as in 1971 Costain became the first UK contractor to win the Queen's Award for Export Achievement - and has since won nine further Queen's Awards. Indeed, during the early 1970s, more than half the Group's turnover came from international operations in 25 countries.
The shape of Costain is constantly changing as new markets are embraced, but the unique Costain way of incorporating in-depth attention to detail and service remains.
