Retentions Ban: Fine in Theory, Unclear in Practice

Why It Matters

Eliminating retentions could improve cash flow for subcontractors but also forces employers to find costly or complex substitutes, reshaping risk allocation across the construction supply chain.

Key Takeaways

• Government proposes outright ban on construction retentions
• Option A favored for lower legislative cost and simplicity
• Employers may shift to milestone payments or escrow accounts
• Bond and project bank solutions remain costly for smaller projects
• Transition period of 12‑24 months suggested for industry adjustment

Pulse Analysis

Retention sums have long been a safety valve for main contractors, ensuring that subcontractors meet quality and safety standards before receiving final payment. The Department for Business & Trade’s latest consultation builds on the Construction Playbook and the Procurement Act 2023, recommending a full prohibition of retentions. By amending the Housing Grants, Construction and Regeneration Act 1996, the government aims to simplify payment practices and curb unfair withholding, a move welcomed by many subcontractors who struggle with delayed cash flow.

If the ban proceeds, employers will need to redesign payment structures. Milestone‑linked payments, where larger sums are held until practical completion, can mimic the financial incentive of retentions without breaching the new rule. Project bank accounts or escrow arrangements offer another pathway, but they introduce administrative overhead and may be prohibitive for smaller projects. Performance bonds and retention bonds, while theoretically viable, remain expensive and difficult to secure for most firms, suggesting that a market‑wide shift to these instruments could increase overall project costs and limit their adoption.

The broader industry impact hinges on balancing contractor protection with cash‑flow realities. A 12‑ to 24‑month transition period gives parties time to renegotiate contracts, develop alternative assurance mechanisms, and adjust financial planning. However, without a clear, low‑cost substitute, some employers may face higher risk exposure for latent defects, potentially driving up insurance premiums or prompting stricter inspection regimes. The outcome of this policy will signal how the UK construction sector navigates payment reform while maintaining the quality and safety standards mandated by the Building Safety Act 2022.
