What is Practical Completion?

Full Definition

Practical completion is a milestone in a construction contract, most commonly certified under standard forms such as the Joint Contracts Tribunal (JCT) suite, marking the point at which the works are sufficiently complete that the client can take possession of the building and begin using it for its intended purpose, notwithstanding that some minor items of outstanding or defective work -- often called "snagging" -- may still need to be completed or corrected. English law does not provide a single, precise statutory definition of practical completion, and case law has generally held it to mean the works are complete for all practical purposes, free of any patent (visible) defects other than trifling ones that would not prevent the building being used and enjoyed as intended, leaving the contract administrator, employer's agent or architect responsible for certifying the contract with the professional judgement to assess whether that threshold has been met on any given project. Practical completion triggers several important legal and financial consequences under most standard form contracts: the defects liability period begins to run from the date of practical completion, typically lasting six or twelve months, during which the contractor remains obliged to return and fix defects that emerge, rather than the client having to pay someone else and claim the cost back; responsibility for insuring the building against risks such as fire typically transfers from the contractor to the client at practical completion; liquidated damages for late completion (a pre-agreed daily or weekly rate of compensation for delay) stop accruing once practical completion is certified, since the works are no longer "late" once this milestone is reached; and, as noted above, a proportion of any retention monies withheld from interim payments is typically released to the contractor at this point, with the balance held back until the end of the defects liability period. Disputes over whether practical completion has genuinely been achieved are common and can be commercially significant, since a client keen to avoid paying liquidated damages exposure or eager to occupy a building may be tempted to certify practical completion prematurely, while a contractor anxious to trigger retention release and stop the liquidated damages clock running may push for early certification even where meaningful defects remain; because of this tension, well-drafted contracts and experienced contract administrators generally require the works to be genuinely complete for all practical purposes, with only trifling defects outstanding, before certifying, and a certificate issued too readily can itself become the subject of a dispute if the client later discovers the building was not, in fact, fit to occupy on the date certified.
