Top 100 Construction Companies 2026
Although geopolitical upheavals continue to threaten economic stability worldwide, the UK’s 100 leading construction firms seem to be gathering strength, albeit incrementally. Most of these bigger firms have the resilience to withstand the rising cost of materials and labour but the same cannot be said for the smaller firms further down the supply chain. Steve Menary reports.
After years of political turmoil at home and abroad, the UK construction industry’s financial fortunes appear to be firming up. But a gap is beginning to emerge between the major players and smaller firms, with the latter struggling to cope with a growing cost base.
