Overall, the top 100 construction companies in London won £11.9 billion-worth of work last year according to Glenigan data.

Morgan Sindall topped the 100 construction companies in London league table last year with an order book just over £1.1 billion. This total comprises more than a third of Morgan Sindall’s national order book with the company’s fit-out division Overbury providing a large swathe of this work in London.

Overbury’s work ranges from the £350 million Project Saturn to fit-out 25 Canada Square (Project ID: 21367875) to a £69.8 million job for alterations to the European Bank of Reconstruction & Development’s offices in Tower Hamlets (Project ID: 21157002).

Capital focus

ISG - another contractor with a strong fit-out division - was ranked second in the top 100 construction companies in London with £780 million-worth of work in the capital. The six biggest contracts won last year by ISG were all based in the capital including a £100 million revamp of Barclays Bank’s offices in Canary Wharf (Project ID: 21414449)

Buying to let

McAleer & Rushe ran in third place courtesy of a pair of buy to-let residential schemes in Wandsworth being developed by Legal & General (Project IDs: 15342535 & 16312834).

London booming

The biggest contract awarded last year was a £400 million contract to Multiplex Construction Europe for the 30 Grosvenor Square scheme in Westminster (Project ID: 16118198). This award helped the Australian-owned company up to seventh in the 2021 Top 100, where a total of 27 companies had order books totalling £100 million or more.
