Practical completion checklist: what developers need signed off

What signing off a scheme means under a building contract

Practical completion is the contractual milestone that confirms a building is finished enough to be handed over and used, leaving only minor snagging to be put right later. It is a creature of the building contract rather than statute, so the wording of the contract governs what has to be true before anyone signs. On most residential and mixed schemes that contract is a Joint Contracts Tribunal, or JCT, form, whose clauses set out who certifies completion, what the certificate does and what has to follow it.

The person who signs is the certifier named in the contract. Under a JCT Standard Building Contract that is the contract administrator or architect, while under a JCT Design and Build contract it is the employer's agent, who issues a practical completion statement to the same effect. Their job at this point is to decide, on inspection, whether the works are genuinely complete save for trivial items. A certificate signed while material defects are still open is open to challenge, and a challenged completion date unsettles everything built on top of it, including the finance.

So the checklist matters as a working document, not a formality. Sign-off is not a single signature; it is a bundle of confirmations that together prove the building is complete, compliant and safe to occupy. The certifier assembles most of it, the developer chases the rest, and a lender funding the exit expects to see all of it before releasing money against the finished asset.

The completion document pack, item by item

The checklist below is the pack a developer should have collated by the completion date, written in the order the documents tend to arrive: from the certificate that anchors everything to the statutory and warranty items a buyer, a solicitor and a lender each want to inspect. Treat it as the master list to work down before you ask a lender to draw the exit facility.

1. Practical completion certificate: the anchor document, issued by the certifier, recording the actual completion date and confirming the works are finished bar the snagging.
2. Building control completion certificate: the sign-off confirming the works comply with the Building Regulations, issued by the building control body, whether the local authority or an approved inspector.
3. Structural warranty: NHBC Buildmark, LABC Warranty, Premier Guarantee or an equivalent latent-defects policy on new residential units, with the final certificate or cover note in hand.
4. Collateral warranties: direct contractual rights for the developer, buyers and the lender against the architect, the main contractor and the key design consultants, backed by their professional indemnity insurance.
5. Professional Consultant's Certificate: where no structural warranty is in place, a named consultant standing behind the design and construction for a set period.
6. Energy Performance Certificate (EPC): a valid EPC for each completed unit, needed before any unit can be sold or let.
7. Gas safety and electrical certificates: a Gas Safe certificate for the installation and an Electrical Installation Condition Report or equivalent electrical sign-off.
8. Fire safety sign-off: an EWS1 form where the scheme is a higher residential block, plus the fire strategy and any building safety documentation the block requires.
9. Planning condition discharge: written confirmation from the local planning authority that the pre-occupation and other relevant conditions on the consent have been discharged.
10. Snagging schedule: the agreed list of minor items to be made good during the defects period, with responsibilities and timescales noted.

Two items catch developers out more than any other. Planning condition discharge is often assumed to happen automatically at completion when it needs a separate application to the planning authority, and an undischarged pre-occupation condition can stop units being sold. The structural warranty is the second: cover has to be arranged early in the build, not at the end, so a scheme that completes without one may only have a Professional Consultant's Certificate to offer, which narrows the pool of lenders and buyers.

Who puts their name to each document

No single party signs off a completed scheme. Certification is split across the certifier, the building control body and the warranty provider, and a lender wants the right name against each line before it treats the building as fundable. The table sets out who signs what and what their signature confirms.

The distinction that trips people up is that practical completion is certified by the contract administrator under the building contract, whereas statutory compliance is signed off by building control. They are separate roles on separate timetables, and one can be signed while the other is outstanding. A scheme can hold a practical completion certificate with the building control certificate a few weeks behind, but a lender funding the exit normally wants both, because it is buying certainty that the building is contractually complete and legally compliant.

How the completion pack releases the exit drawdown

For a developer, the completion checklist is not just a construction formality; it is the evidence file a finance drawdown depends on. A development exit bridge is a short-term facility that repays a maturing development loan once the build risk has gone, and the way a lender confirms that is by inspecting the completion pack. The certificate proves the works are finished, the building control and warranty documents prove they are compliant and insured, and the valuer relies on all of it to value the finished units.

It pays to plan backwards: the facility can only draw once legals complete, and legals only complete once the title, planning and sign-off documents check out. Working the pack early avoids a maturing development loan slipping into a penalty or default rate while the certificate is still being chased. The wider structure of the facility sits on our pillar page at /solutions/development-exit-loans/.

Funding at wind and watertight versus certified completion

Not every developer waits for the certificate to refinance. There are two common points at which the development debt can be replaced, carrying different evidence and pricing. The earlier point is wind and watertight, meaning the external envelope, the roof, the walls and the windows, has been sealed against the weather while the fit-out and sign-offs are still to come. The later point is certified practical completion, where the full checklist is in place.

In practice we place both. Where a scheme is finished and the pack is complete, an exit bridge steps in cleanly against certified completion; where a developer needs to move earlier, a part-complete or finish-and-exit structure can sometimes be arranged against a monitored path to completion, and the two stages are compared in our guide at /learn/wind-and-watertight-vs-practical-completion/. Lenders such as Shawbrook, United Trust Bank, Octane Capital and Together publicly operate in this market; criteria change constantly and nothing here is an offer of finance.

Where certification slips and holds up a drawdown

Most delays to an exit drawdown are not about the money; they are about a missing or contested document. Knowing where certification tends to slip lets a developer front-load the fixes rather than discover them at valuation. The table sets out the common failure points and the practical response to each.

The disputed certificate is the failure with the longest tail. If the certifier will not sign because material defects are still open, and the contractor argues the works are complete, the completion date is unsettled and any drawdown sized on a finished asset stalls until it is resolved. The leading case law holds that only trivial defects can be outstanding, so a completion date that can be challenged is a completion date a lender will not fund against.

Snagging schedules and the retention that follows completion

Reaching completion does not close the contract, and the checklist reflects that. Two mechanisms carry on past the certificate: the snagging schedule and the retention. The snagging schedule is the agreed list of minor items the contractor returns to make good during the defects liability period, also called the rectification period, which typically runs for six or twelve months after completion. A short list of cosmetic items is normal and consistent with a valid completion; a long list of material defects is a sign the scheme was signed off too early.

Retention is the slice of the contract sum the developer holds back as security against those defects. The usual pattern is that around half is released to the contractor at practical completion, with the balance held until the defects are made good and the certifier issues the final certificate at final completion. That is the practical difference between the two milestones: the first releases half the retention and starts the defects period, the second releases the rest once the snagging is cleared.

Both figures feed the finance, because the retention held back and the cost of any outstanding snagging affect the net cash a scheme produces, so an exit facility is sized around where the numbers stand at completion rather than a notional finished value. We assemble the completion pack, match the finished scheme to a lender whose appetite fits it, and arrange the take-out by sales or refinance ahead of time. Development Exit Property Finance arranges and introduces finance rather than lending it, and holds no authorisation from the Financial Conduct Authority; the lending we place is unregulated commercial debt, and any figure we cite is illustrative rather than an offer of finance.
