Document background
The Certificate of Completion Language is a critical document used in England and Wales to formally declare that contracted works have reached practical completion. It is typically issued when works have been completed to a standard where the client can take possession and use the facility for its intended purpose, even if minor defects remain to be addressed. The certificate triggers several important contractual consequences, including the release of retention monies, transfer of insurance responsibilities, and the start of the defects liability period. It should be used when works have reached a stage where they are substantially complete and any remaining items are minor in nature and do not affect the normal use of the facility.
