Last updated 30/6/2026 · Reviewed 30/6/2026

Retention release: half at handover, half 6 months later. Don't release until the snag is closed or in writing agreed. The retention is your leverage against defects. Most contracts hold 5% retention until snag closure. Some hold 2.5% for 12 months and 2.5% for 24 months (longer retention for latent defects). Document the snag closure in writing. Get the Assigned Certifier to confirm before each release. The first release (half at handover) is conditional on the snag list being agreed and a programme for closure. The second release (half at 6 months) is conditional on the snag being closed. Some contracts have a third retention (2.5% at 24 months) for latent defects. Check your contract.
