Completion, snagging and handover: before you move in

The last weeks of a self-build are among the busiest and most important. Each step has to happen in the right order.

Eight steps to moving in

StepWhat happens
01 Practical completionThe work is substantially complete. The defects period starts, half the retention is released and the site passes back to you.
02 Snagging inspectionA systematic walk through the house, recording defects and unfinished items. The list goes to the builder in writing.
03 Snags put rightMajor items before you move in; minor cosmetic items can follow.
04 Completion Certificate submittedThrough eBuilding Standards, confirming the work matches the warrant.
05 Building Standards inspectionThe council checks the house against the approved warrant.
06 AcceptanceThe Completion Certificate is accepted. You need this to move in, for your lender and for your VAT claim.
07 Moving in and final paymentThe certified balance is paid to the builder, less the retention still held.
08 VAT reclaimWithin six months of completion.

Hold on to the retention

Don't release it early

The retention held for the defects period is your leverage for snagging and first-year defects, however hard the builder presses for it.

Get the snagging right

Snagging is your last real leverage over quality before the builder leaves site. A room-by-room approach catches far more than a walk-through.

Don't forget the VAT claim

It's easy to let the claim slip after moving in, but the six-month deadline is fixed.

Questions

Can I move in before the Completion Certificate is accepted?

Not without the council agreeing to temporary occupation. Moving in early can also cause problems with your lender, insurance and VAT claim.

What if Building Standards finds a problem?

It's put right and the certificate is resubmitted, which can add weeks. Keeping on top of notifications during the build avoids most surprises.
