The risk
Retention withholds part of certified payment. A guarantee is a separate undertaking whose wording determines when it can be called.
The control
The contract should state percentages, caps, reductions, expiry and release conditions. Guarantees must match the required form and contracting parties.
Evidence on site
Reconcile withheld amounts on every certificate and diarise guarantee expiry. Extensions should be agreed before cover lapses.
Closing the record
Release should follow the contract’s completion and defects milestones. Unclear administration creates avoidable disputes and cash pressure.
Editorial note
This article provides general construction information from the official reference below. Project requirements depend on the current law, contract, design and site conditions, and should be confirmed by the responsible competent person.
What we will track next
The strongest follow-up to Retention and guarantees solve different payment risks is an auditable chain from decision to outcome. Scope, authority, quotation, approval, delivery and payment should agree, with changes recorded while the work is active.
Commercial records are project controls, not end-of-job paperwork. A current programme, cost forecast, instruction register and payment history let the team address risk early and give reviewers evidence for the final account.
