Practical Completion
Also known as PC
Definition
Practical completion, or PC, is the point at which the works are finished enough for the client to take over and use the building, even if minor snags remain. It marks handover and starts several contractual clocks. At PC, responsibility for the building usually passes to the client, the first half of retention is often released and the defects liability period begins. It is a key milestone in any building contract.
Practical completion does not mean every last item is perfect, it means the building is safe to occupy and fit for its purpose, with only minor snags outstanding. A certificate is usually issued to confirm it.
From that date the client takes over insurance and possession, the defects liability period runs, and payment and retention milestones are triggered.
Why it matters
Practical completion is the moment your job tips from spending to getting paid. It releases retention, ends your liability for delay and starts the defects clock. Knowing exactly what PC requires helps you hit handover cleanly and unlock the money tied up in the job.
