What is a main contractor?
A main contractor, also called a principal or tier 1 contractor, signs the contract with the client and is responsible for delivering the project. Most of the work on site is usually done by subcontractors and suppliers, who the main contractor appoints, manages and pays. Tier 1 usually means the large contractors working directly for clients on major projects. Tier 2 and tier 3 firms work for them further down the supply chain.
The largest UK main contractors
By revenue in their latest results, the biggest are Balfour Beatty (£9.5bn), Morgan Sindall (£5.0bn), Kier (£4.4bn), M Group (£3.1bn), Mace (£2.8bn). The full top 20 above includes infrastructure and utilities groups as well as building contractors, and each figure links to its source.
How to check a main contractor before you sign
- How quickly it pays. Large companies report their payment times to the government every six months. Across the 122 companies on our payment league table, the middle figure is 31 days.
- Its accounts and filings. Late accounts, losses, auditors' going concern warnings and insolvency notices all show up in each company's CR Signals.
- Its history. Has it, or a company in its group, failed before? Search the failures register and see the biggest UK construction failures.
- Your exposure. The cash tied up calculator shows how much of your money a package could tie up, using the contractor's own payment days.
