Top 100 Construction Companies 2025
Despite ongoing concerns over economic fragility, geopolitical upheavals and even the legacy of Brexit, the financial health of the UK鈥檚 100 leading construction firms appears to be improving. The challenges that remain are real, however, and in particular, the spectre of project delays is already looming. Steve Menary reports.
This year鈥檚 review of the Top 100 UK contractors is based on an analysis of the companies鈥� financial results filed up until the end of June 2025. A cursory glance at the main runners and riders reveals few surprises: Balfour Beatty returns to its customary number one position (having been elbowed into second place by Morgan Sindall last year) and the usual suspects 鈥� Kier, Wates, Laing O鈥橰ourke, Mace etc 鈥� are still clustered at the top of the table.
