UK cash retentions ban: commercial and risk implications for project teams

30 Second Briefing
The UK government’s proposed ban on cash retentions in construction, following a year-long consultation, is being hailed by trade bodies such as the ECA and NFRC as a long-fought win for specialist contractors previously exposed to withheld payments used as free working capital. Legal and commercial advisers including Kennedy’s Amanda Hanmore and Osborne Clarke’s Daniel Cashmore warn the ban could drive higher project costs via performance bonds, more back‑loaded payment schedules and milestone‑only payments, and trigger more disputes over incomplete or defective works. BCIS chief economist David Crosthwaite points to project bank accounts and alternative defects and quality mechanisms as critical to maintaining delivery standards and payment security across supply chains.
Technical Brief
- ECA’s Rob Driscoll warns of “back-door loopholes”, signalling likely complex drafting in standard forms and amendments.
- BCIS’ David Crosthwaite stresses retentions’ historic role in defects liability and quality assurance, requiring robust replacement mechanisms to protect asset performance.
- Legal advisers at Kennedys anticipate “radical changes” in standard form construction contracts, including redefined withholding, certification and defect-rectification provisions.
- Osborne Clarke’s Daniel Cashmore flags increased recourse to adjudication and courts for incomplete/defective works once the retention “pot” disappears.
- Alternatives cited—project bank accounts, milestone-only payments and performance bonds—shift risk allocation and may tighten compliance with specification and completion criteria.
Our Take
Because this item sits at the intersection of the Standard/Guideline and Safety tags, it signals that retention practices are being framed not just as a cashflow or contract-award issue but as a mechanism tied to quality and safety performance on UK construction projects.
In our database, UK Policy items that involve professional advisers such as Osborne Clarke and BCIS typically feed into formalised guidance notes or model clauses, suggesting contractors should watch for forthcoming template wording they can adopt or be asked to accept on new frameworks.
