What is the completion certificate chain, and how does it affect handover?
Final inspections → conformity certification → occupancy permission. It runs at the end, in series, with external parties — and it fixes the handover date every bit as firmly as the snag list does. The difference is that everybody watches the snag list.
The chain runs in series, at the worst possible time
Final authority inspections have to happen before conformity certification, which has to happen before occupancy permission. Each step involves an external body with its own queue, its own document requirements, and no particular investment in your handover date.
And it all runs at the end of the project, concurrently with the snagging, the commissioning and the client walkthroughs — which is to say, at the moment when the project has the least spare capacity and the most people asking questions.
Everybody watches the wrong list
The snag list is visible. It is discussed weekly, it has an owner, it has a burn-down chart, and the whole team can see it shrinking.
The certificate chain usually has none of that. It sits with one person, tracked in a spreadsheet, and it determines the handover date just as absolutely — a building with zero snags and no occupancy permission cannot be handed over, and a building with occupancy permission and a hundred snags very often can.
What to do about it
Put the chain on the programme, in series, with realistic durations and a named owner. Work backwards from the handover date and see when the first inspection actually has to be booked — the answer is usually earlier than anyone assumed.
And keep the answer to “what is still blocking occupancy?” current on any ordinary Tuesday, rather than assembling it in a panic in the final fortnight from a filing cabinet and three people’s memories.
