Why a formal handover checklist matters

Practical completion is one of the most significant moments in any construction contract. It triggers the release of retention, starts the defects liability period, transfers insurance responsibility to the client and - if not handled properly - can lead to disputes about what was and was not complete at handover.

A signed handover checklist gives both parties a clear, dated record of the condition of the works at the point of handover. If a defect surfaces six months later, the checklist establishes whether it was identified at the time or emerged afterwards during the defects liability period.

Carry out your own internal snagging first. Before inviting the client to the formal handover inspection, walk the site yourself with a snag list and resolve every item you can. A short client snag list reflects well on the quality of the build. A long one creates doubt.

What the template covers

Practical completion vs final completion

Practical completion does not mean the project is 100% finished - it means it is substantially complete and fit for occupation. Minor snagging items can remain, but the building must be safe, weather-tight and usable. The outstanding items table in this template captures anything that falls into that category.

Final completion - sometimes called making good of defects - occurs at the end of the defects liability period (typically 6 or 12 months) when all defects notified during that period have been rectified and the final retention is released.

When to use this checklist

The checklist is designed to be used at the formal handover inspection immediately before or on the date of practical completion. Both the contractor's representative and the client (or their contract administrator or architect) should walk the property together, working through the checklist section by section. Any item that does not pass should be noted, with a target date for resolution agreed on the day.

Frequently asked questions

What is practical completion in construction?
Practical completion (PC) is the point at which the works are finished to the extent that the client can take possession and use the building for its intended purpose, even if minor snagging items remain. Under most JCT contracts, PC triggers the release of the first half of the retention, the start of the defects liability period, and the transfer of insurance responsibility to the client.
What is a defects liability period?
The defects liability period (DLP) - sometimes called the rectification period - is the period after practical completion during which the contractor is obliged to return and fix any defects that emerge. It is typically 6 or 12 months under standard contracts. At the end of the DLP, a final inspection is carried out and the remaining retention is released if no defects remain.
Should I carry out my own snagging before the client's handover inspection?
Yes. The contractor should always carry out an internal snagging inspection before inviting the client or contract administrator to the formal handover. This minimises the formal snag list, demonstrates professionalism and avoids the client identifying defects the contractor should have caught themselves. Use our snag list template for the pre-handover internal check.
What documents should be handed over at practical completion?
The core documents are: Building Control Completion Certificate, Electrical Installation Certificate, Gas Safe commissioning certificate (if applicable), boiler service record and warranty, FENSA or equivalent certificate for new windows, product warranties, O&M manuals, as-built drawings if applicable, planning permission and discharge of condition letters, and meter readings taken on the day of handover. The documentation checklist in this template covers all of these.
