Best UK business loans for construction

What is the best business loan for a UK construction company?
For plant and equipment, asset finance from Allica Bank or Aldermore. For working capital across CIS retentions and stage payments, an iwoca flexi-loan. For owned yards and offices, an Allica or Shawbrook commercial mortgage.
How do CIS retentions affect UK construction lending?
CIS retentions (typically 5% of contract value held against defects) lock cash in for 6 to 12 months. Lenders that understand construction underwrite on net-of-retention turnover. Generalist lenders often miss this and over-decline.
Can UK subcontractors with stage-payment cycles get finance?
Yes, but invoice finance fits better than term debt for the working-capital piece. iwoca flexi-loan covers shorter gaps. Term debt suits asset purchases and one-off investments, not the recurring stage-payment cash trap.
What is the typical asset finance rate for UK construction plant?
Hire purchase on plant typically prices at 7% to 12% APR depending on age of asset, deposit and credit profile. Used plant prices higher than new. Established Ltd contractors with clean credit reach the cleaner end.
Do main contractors and subcontractors face different lending criteria?
Yes. Main contractors are underwritten on contract pipeline and end-client quality. Subcontractors are underwritten on main-contractor concentration risk; high reliance on one main is itself a decline reason at some lenders.
