Understanding retention and staged payments in construction
In UK construction contracts, it’s common for clients to withhold a percentage of payment (retention) to cover potential defects. Payments are also staged around project milestones rather than being released all at once. While this protects the client, it creates pressure on contractors who must fund labour, materials and overheads upfront.
Common cash flow pressures contractors face
- Retention holdbacks: Typically 3–5% of the contract value, sometimes withheld until months after completion.
-
Slow milestone approvals: Staged payments often depend on sign-offs, which can delay cash flow.
-
Mismatch of costs vs payments: Expenses for staff, suppliers and equipment run continuously, while payments come in chunks.
Practical ways to manage cash flow under retention
- Negotiate fairer retention terms: Push for lower retention percentages or earlier release of funds. Even reducing retention by 1–2% can free up valuable cash.
-
Align staged payments with real costs: Structure your payment schedule so it reflects when you incur heavy costs, such as materials ordering or subcontractor payments.
-
Track project progress closely: Detailed progress reporting helps you get staged payments approved faster and avoid disputes.
- Build in contingency: Plan for delays in staged payment release by holding a cash buffer or arranging a funding line.
Funding options to bridge the gap
- Invoice finance: Releasing cash against staged invoices raised to clients.
-
Short-term loans: To cover gaps until retention or milestone payments are received.
- Project finance: Tailored facilities that match construction cash flow cycles.
