What Is Practical Completion in Construction?
Practical completion is one of the most important milestones in a construction project. It's the point at which the contractor hands the finished project back to the client — but "practical" is a precise term, not a casual one. Understanding what it means, what your contractor's obligations are at that point, and what happens next is essential for any homeowner undertaking a significant build.
The Definition of Practical Completion
Practical completion — sometimes abbreviated to PC — is the point at which the works are complete in all practical respects, even if minor items (often called a "snagging list" or "defects list") remain outstanding. The key concept is that the building is sufficiently complete to be used for its intended purpose, even if small finishing items haven't been addressed.
Practical completion is not the same as absolute completion (sometimes called "final completion"). At practical completion, minor outstanding items are noted and recorded — but the building is handed over to the client. Those outstanding items are typically addressed in a short period after handover, during what's called the defects liability period.
What Happens at Practical Completion
The client takes possession. The client takes over the building and responsibility for insurance shifts from the contractor to the client (under most standard contract forms). The contractor's right of access to the site typically requires the client's permission from this point.
The defects liability period begins. A defined period — typically 6 or 12 months under standard contract forms — during which the contractor is obliged to return to remedy any defects that emerge from the works. This is distinct from snagging (minor items visible at handover) — it covers latent defects that only become apparent in use.
Retention (if applicable) is partially released. Under many formal contracts, retention money is held by the client against the contractor's performance. At practical completion, half the retention is typically released, with the remainder released at the end of the defects liability period.
Liquidated damages stop accruing. If the contract includes a liquidated damages clause (a pre-agreed sum per day or week of delay), these stop accruing at practical completion.
The Snagging Process
A snagging list records items that are incomplete or below the required standard at the point of practical completion. Good snagging practice involves a joint inspection between the client and contractor (or an independent third party) before practical completion is certified. Items on the snagging list should be specific, photographed, and agreed in writing — with a programme for their resolution.
Snagging should not be used to dispute fundamental scope items or to avoid practical completion on items that are genuinely complete. The test is: is the building practically ready for occupation? Not: is it absolutely perfect in every detail?
Practical Completion on Domestic Projects Without a Formal Contract
Many domestic projects run without a formal JCT contract. In these cases, "practical completion" as a contractual concept may not exist — but the same principles apply informally. The point at which you take possession, pay the final invoice, and accept the works is functionally equivalent to practical completion. This makes it important to record any outstanding items in writing before final payment is made, rather than assuming they'll be resolved after you've settled the account.
