Submission and acceptance
The Completion Certificate is a two-step process. You submit the certificate, and Building Standards accepts or rejects it. The document that matters is the acceptance, not the submission.
Why acceptance matters
- Occupation. It's an offence to occupy a new building before the Completion Certificate has been accepted, unless the council has allowed temporary occupation.
- Mortgage. Lenders need it for the final drawdown.
- Selling. Buyers' solicitors and lenders ask for the warrant and the accepted Completion Certificate.
- VAT reclaim. HMRC's DIY Housebuilders Scheme claim relies on proof of completion.
Claims under the DIY Housebuilders Scheme must be made within six months of completion, extended from three months for homes completed from 5 December 2023.
The four steps
- Finish the work covered by the warrant, including every notification stage.
- Submit the Completion Certificate through eBuilding Standards.
- Final inspection by Building Standards against the approved drawings.
- Acceptance is issued if everything is in order.
Acceptance of the Completion Certificate is a statutory step with the council. It is separate from practical completion, which is a stage under your building contract, and from handover of the house to you. Practical completion, snagging and final payment to the contractor happen around the same time, but each follows its own process. See our guide to completion and handover.

Questions
Can I move in before the Completion Certificate is accepted?
Not without the council's agreement to temporary occupation. Occupying a new building without an accepted Completion Certificate is an offence.
How long do I have to claim VAT back on a self-build?
Six months from completion, for homes completed on or after 5 December 2023.
