2026 UK Cash Retention Ban: A Construction Checklist from Practitioners
The UK government has announced plans to ban cash retentions in construction contracts, but no ban exists yet. Current contract terms and statutory payment rules still govern how much you can withhold and when. If you hold or receive retentions today, check your contract wording now, start weighing up alternatives such as bonds or a retention deposit scheme, and keep an eye on the consultation as it progresses.
TL;DR:
UK construction contracts typically withhold between 1.5% and 5% of interim payments, usually released in two stages after practical completion and defect correction.
Existing statutory payment rules require clear notices and deadlines, and any ambiguity in certification or trigger wording is a major source of disputes over retention releases.
The government’s proposed ban on cash retentions is not yet law, but businesses should start preparing by exploring bonds, deposit schemes, and adjusting payment schedules now.
Alternatives like retention deposits, bonds, or parent guarantees add administrative complexity, costs, and require early cost assessments to be effective when the ban becomes law.
Contractors and clients should review and clarify retention clauses, verify payment practices, document progress meticulously, and aim for transparent certification to mitigate retention-related issues.

What is retention in construction and how does it work?
Retention in construction is a sum withheld from interim payments as security against unfinished work or defects. Clients and main contractors use it because it gives them leverage: if a contractor walks off site with snagging left undone, there’s money held back to cover the fix.
There’s no fixed statutory percentage. Rates are contract-specific, though industry reporting shows typical UK retention sits between 1.5% and 5%, with standard forms like JCT commonly citing 3% or 5% as the default figure.
Release usually happens in two stages:
Half the retained sum at practical completion, when the building is fit for use even if minor items remain outstanding.
The remainder after the defects liability period ends, once any snagging has been fixed and signed off.
The exact triggers depend entirely on your contract’s certification clauses, which is exactly where disputes tend to start.
Retention rarely stops with the main contractor. When a client withholds 5% from the main contractor, that main contractor typically mirrors the same clause against subcontractors, and subcontractors often do the same to their own suppliers. A modest percentage at the top of the chain compounds into serious cash-flow strain several tiers down, particularly for smaller trades with thin margins.
Pro Tip: Before signing any subcontract, check whether your retention release is tied to your own completion certificate or to the main contract’s completion date. The two dates are rarely the same, and being paid on someone else’s timetable can leave you waiting months longer than expected.
How does UK law regulate retention payments?
Retention sits inside a broader framework of statutory payment rules, and getting the mechanics wrong costs more than the retention itself.
Payment notices are mandatory. Under the Housing Grants, Construction and Regeneration Act 1996, every construction contract must set a payment date and a final date for payment. After that final date, a payer cannot withhold any sum, including retention, unless they’ve served a valid pay-less notice within the deadline the contract sets.
The Scheme fills the gaps. Where a contract fails to set out adequate payment mechanisms, the Scheme for Construction Contracts supplies default terms automatically, including a 17-day final date for payment on relevant applications. This exists precisely so a poorly drafted contract can’t be used to delay payment indefinitely.
CIS tax treatment follows the payment date, not the work date. HMRC’s guidance confirms that retention payments are treated the same as any other payment under the Construction Industry Scheme, but the tax deduction rate applied is whatever the subcontractor’s registration status is on the day the retention is actually paid, not when the original work was carried out. Retentions held for two or three years can easily see a subcontractor’s status change in that time, which shifts what gets deducted.
Drafting traps matter more than the headline rate. The 2011 amendments to the Construction Act specifically forbid making a subcontractor’s payment conditional on an unrelated event in a different contract. Any clause tying your retention release to “when the main contractor gets paid by the client” is on shaky legal ground.
Before signing anything, check exactly how practical completion, defects, and certificate triggers are defined, and confirm the deadline for serving a pay-less notice. Vague wording in these three areas causes the majority of retention disputes.
What does the 2026 government proposal on retention actually say?
The government’s own response describes this as part of the largest crackdown on late payments in over 25 years.
None of this is law yet. It’s a policy direction that still needs drafting, further consultation, and almost certainly anti-avoidance provisions to stop retention clauses simply being renamed or restructured to dodge the ban.
Expect these effects while the detail is worked out:
Rising demand for bonds and guarantees as businesses start hedging against the ban landing sooner than expected.
Some renegotiation of payment schedules as parties try to work out where the security retention used to provide will now sit.
A likely short-term uptick in disputes and adjudications as contract wording gets tested against a legal position that’s still in flux.
Watch the GOV.UK consultation pages, any Construction Leadership Council guidance on surety markets, and draft legislative clauses as they emerge. Reacting only once the Act is passed will leave you negotiating from a weaker position than businesses that started planning now.
Alternatives to cash retention worth considering now
If cash retention is heading for the exit eventually, it’s worth understanding what typically replaces it and where each option’s trade-offs sit.
Retention deposit scheme (RDS). Retained sums sit in a ring-fenced trust account rather than the payer’s general funds, protecting the money from the payer’s insolvency. It adds administrative overhead, someone has to manage the account and reconcile releases, but it directly solves the insolvency-risk problem that BEIS and Pye Tait’s research flagged as a recurring industry concern.
Retention bonds and performance bonds. A surety guarantees payment up to a set value if the contractor fails to perform, so no cash is actually withheld from interim payments. The catch is cost: smaller firms often face higher premiums relative to contract value, and most bonds require a counterindemnity that can tie up a firm’s own credit lines.
Parent company guarantees. Where a subcontractor sits within a larger group, a guarantee from the parent can substitute for retention entirely, though it only works where the parent’s balance sheet is genuinely strong enough to reassure the client.
Supporters of abolition argue cash retention simply locks up money that should be funding wages and materials further down the chain. Critics counter that the UK’s surety market may not have capacity to absorb sudden demand for bonds at scale, which could push costs up rather than down.
Pro Tip: Ask your bank or broker for an indicative bond premium now, even if you don’t need one yet. Knowing the real cost of the alternative before it becomes compulsory puts you in a far stronger position when a client suddenly insists on it.
Practical checklist for clients and contractors right now
Rewrite retention clauses for clarity. Spell out exactly what triggers release, practical completion, defects certificate, making-good certificate, and make sure none of it depends on an unrelated event in a different contract.
Run due diligence on payment practices. Larger businesses must publish payment practices and performance reports; check a prospective client’s or contractor’s history before signing, and confirm whether retention terms are mirrored consistently up and down your own supply chain.
Model the real cost of alternatives. Get indicative bond and guarantee pricing from a surety provider before you need it, so you’re negotiating with numbers rather than guesswork if a client proposes swapping retention for a bond mid-project.
Keep dispute-ready records. Document every inspection, making-good certificate, and notice you send or receive. Most retention disputes come down to who can prove certification happened and when, and understanding your adjudication and suspension rights under the Construction Act gives you real leverage if a payer stalls.
Firms managing workforce planning around uncertain payment timing may also find it useful to consider how payment delays ripple into scheduling and hiring decisions further down the chain.
Why clear certification is the real fix, not just contract wording
Most retention disputes we see aren’t really about the percentage withheld. They’re about who controls certification and whether the release triggers were ever written down clearly in the first place.
That’s precisely why we run every EvoStruct project with transparent, staged quoting and live virtual tours: clients can see workmanship and progress in real time, which removes the guesswork that normally fuels a disputed retention withholding. Clear milestones and prompt certification mean releases happen on schedule, not after weeks of argument.

FAQ
Is there a ban on construction retentions in the UK?
Not yet. The government has announced its intention to ban cash retentions, but this requires further legislation and consultation before it takes effect, so current contracts and statutory rules still apply.
What is the typical retention rate in the construction industry?
There’s no single statutory rate. Practice varies by contract, but reporting shows a common range of 1.5% to 5%, with standard forms like JCT often defaulting to 3% or 5%.
How long is retention held in construction?
Retention is usually released in stages, with some released at practical completion and the rest after the defects liability period ends. The exact duration depends on your contract, but defects periods commonly run for six to twelve months after completion.
What is the 12-year limitation period in construction?
Under a contract executed as a deed, a claim for breach can generally be brought up after a significantly longer period than for a simple contract. This matters for retention because defects can surface long after final release, and understanding your limitation period helps you assess how long you may remain exposed to a claim.
How does EvoStruct help clients manage retention risk?
EvoStruct structures contracts with clear milestones and staged payments, backed by live virtual tours so clients can verify progress before each release point. That transparency reduces the certification disputes that typically delay or complicate retention withholdings.
