IN Brief:
- The UK Government is proposing a ban on retention payments in construction contracts.
- The reform would amend the Housing Grants, Construction and Regeneration Act 1996.
- Alternative security mechanisms such as bonds, guarantees, escrow, and insurance-backed warranties are likely to receive greater attention.
The UK Government is proposing to ban retention payments in construction contracts, setting up one of the most significant changes to construction payment practice in decades.
The proposal would prohibit clauses that allow paying parties to withhold retention sums as security against defects or non-completion. The measure is expected to be delivered through amendments to the Housing Grants, Construction and Regeneration Act 1996.
Retention has long been embedded in standard construction contracting. A percentage of payment is withheld from a contractor or subcontractor, usually released in two stages: the first at practical completion and the second after the rectification or defects period. In practice, that can leave cash tied up for months, and sometimes far longer where disputes, insolvency, or poor administration intervene.
The Government has chosen an outright ban rather than a model that would allow retentions if the money were protected through deposit schemes or guarantees. Transitional provisions are expected, with existing and newly agreed retention clauses remaining effective for a limited period before the ban takes full effect.
The legislation also points to penalties for breach, statutory interest, and the need for industry to develop alternative mechanisms for performance security. That could bring greater use of performance bonds, retention bonds, parent company guarantees, escrow arrangements, project bank accounts, and insurance-backed defects warranties.
The proposed ban follows years of criticism from specialist contractors and SME suppliers. Retentions have been challenged because they restrict cashflow, expose lower-tier businesses to upstream insolvency, and can be used as leverage during final account disputes. For companies already working on thin margins, withheld cash can become the difference between resilience and failure.
Payment reform has already moved into legislation through wider late-payment proposals. Legislation targeting late payment and 60-day terms has placed construction retentions directly inside the reform agenda. The latest legal detail confirms that the issue is moving from consultation into live contractual change for clients, contractors, and advisers.
The strongest pressure for reform comes from lower down the supply chain. Specialist subcontractors carry labour, materials, design development, preliminaries, and overhead costs long before final payment is received. If a main contractor or developer fails while retention is still withheld, the subcontractor may rank as an unsecured creditor despite having completed the work.
The industry will still need a credible answer to defects and completion risk. Retentions have survived partly because they are simple to administer, even if damaging in effect. Removing them requires more disciplined alternatives. Bonds and guarantees carry cost. Escrow arrangements require administration. Insurance-backed warranties need careful drafting. Project bank accounts can improve security but depend on adoption and governance.
Clients and funders are likely to focus on how building quality is protected without cash withholding. That concern is acute after years of building safety scrutiny, product compliance challenges, and greater expectations around golden-thread records. A retention ban cannot weaken quality assurance; it should force better contract administration, clearer defects management, and more transparent security arrangements.
Pricing may also adjust. If contractors must provide alternative security, those costs will be reflected in tenders. Clients may see fewer headline deductions but more explicit risk pricing. One of the long-running criticisms of retentions is that they hide the true cost of security by transferring working-capital pressure to businesses least able to absorb it.
The reform also lands in a fragile specialist contractor market. Recent insolvencies have shown how delayed payments, disputed sums, retention exposure, and upstream failure can compound trading losses. Construction cannot increase output sustainably if the subcontractor base that delivers much of the physical work remains under-capitalised and exposed to avoidable cash shocks.
Implementation detail will be decisive. Standard forms will need amendment, clients will need updated procurement rules, and contractors will need to review subcontract templates. Finance teams will need to understand how alternative security affects cashflow and balance-sheet treatment, while commercial teams will need to avoid recreating retentions under another name.
A ban would not remove disputes from construction. Defects, variations, delays, and final accounts will still generate friction. It would, however, remove a practice that has too often allowed risk to be held as unpaid cash deep in the supply chain. Early preparation will decide whether the reform produces cleaner payment practice or another round of contractual workaround.
