Structural engineers with a long history of service to the construction industry The company was founded in 1865 by Mr Leonard Cooper, an iron and steel merchant based in Leeds.

Some of our earliest steelworks were used in the building of the Malt Kilns on Cardigan Road, Leeds in 1923; the stands at the Headingley Football ground in 1931 and Leeds Regal Cinema, which was built in 1936. 

We now work alongside some of the UK's leading developers, designing and delivering steelwork for a range of new build projects and refurbishment projects.

Our expertise is often called upon to integrate new steel within old structures to extend and marry with new additions whilst retaining the integrity of the building and causing minimal intrusion. Leonard Cooper Ltd, almost 150 years of excellence.
