BTO key collection day: what to prepare and what to inspect.

What actually happens on collection day

You receive an appointment letter from HDB with a date and time. Key collection happens at the HDB Sales Office in HDB Hub, Lorong 6 Toa Payoh, not at your flat. All applicants attend in person; HDB staff take you through the payments and paperwork and hand over your keys and Welcome Kit.

Nobody walks the flat with you at this stage. There is no site engineer pointing out features, and there is no clipboard form to fill in at the unit. You go to the flat afterwards, on your own time, keys in hand.

Your protection is the 12-month Defect Liability Period, which runs from the date of key collection. HDB asks you to report items within the first month and before renovation begins, because once renovation has started it is much harder to establish whether a defect came from the building contractor or your renovation contractor. That is a recommendation about sequencing, not a cut-off: rectification requests can still be submitted at any point in the 12-month DLP. The QR code in your HDB Welcome Kit works from key collection itself, or you can file at the BSC counter in your precinct.

What to bring

• Printed defect checklist: Use HDB’s official Defects Feedback Form, or print our BTO handover checklist. A paper list survives a dropped phone; an electronic one syncs back later.
• Torch: Phone torches work but drain battery and slow you down. A dedicated torch reveals hairline cracks and finishing defects that overhead lighting hides.
• Phone with full battery and storage: Between the paperwork, defect documentation, and meter readings, you will take a lot of photos. Start the day with the battery full and enough free storage so you never have to stop and delete.
• Tape measure: Useful for checking door clearances, tile alignment, and noting the size of cracks for later reference.
• Polarity tester (optional but useful): A cheap plug-in tester from any hardware shop. Plug it into every socket; reversed live and neutral light up immediately. If you cannot bring one, the inspector will catch it later, but it is the easiest defect to flag on day one.
• A second person: One walks and points; the other photographs and notes. The visit is faster and more thorough with two pairs of eyes.

What to inspect at the flat

Take your time in the unit. There is no need to rush, and nothing to sign there. What you report is what the BSC works from when it schedules the joint inspection, so a thorough first list is what gets fixed. Focus on:

• Walls and ceilings: Look at every wall in oblique light from the torch. Note paint runs, missed spots, hairline cracks, plaster bumps, and any stain that suggests prior water exposure.
• Doors and windows: Open and close every door. Doors should latch on first attempt and stay where you put them. Windows should open fully and seal cleanly. Sliding doors should not stick or skip.
• Tiling: Walk every tiled surface. Note any visibly uneven tiles, broken edges, or wide grouting gaps. Hollow tiles require a tap-test; you can do a basic version with a coin, but a full inspection uses a small mallet.
• Plumbing: Run every tap. Watch the drain trap. Flush every toilet. Check shower and basin water pressure. If a tap drips, leaks at the base, or runs slow, photograph it.
• Electrical: Test every socket with your polarity tester. Flip every switch. Note any socket that produces a warning light, any light that does not work, or any switch that feels loose in its plate.
• Bomb shelter: Open and close the door. The rubber seal should sit flush all the way around. Check that the door serial label is present, legible and undefaced, and scan its QR code to confirm the label status reads valid rather than void. If the door does not close cleanly, that is a regulatory issue.

If something is seriously wrong

Because keys are issued at HDB Hub rather than at the flat, there is no handover walkthrough to accept or refuse and nothing to sign at the unit. If you reach the flat and find something that stops it being usable, such as no water supply, a door that will not open, or a plumbing failure, report it to the Building Service Centre straight away and ask for it to be treated as urgent rather than queued with the rest of your list. The decisions that matter on collection day are about defects to record, not handover to refuse.

Filing your list

Report what you find to HDB via the QR code in your Welcome Kit or at the BSC counter. Both produce a reference number; keep that number. File within the first month and before renovation begins if you can, and remember that rectification requests can still be submitted at any point in the 12-month DLP.

The BSC then reviews the list and schedules a joint inspection with the main contractor. At that joint visit, the contractor sees each defect on your list, agrees or contests, and arranges rectification. The joint inspection is scheduled off your initial submission and works from it, so items found later are handled as separate rectification requests rather than in that one coordinated sweep. Inspect thoroughly and submit early.

After collection

Do not move in immediately. Do not start renovation. The first month is for documentation; the joint inspection and rectification happen over the following weeks. Moving furniture and beginning renovation work before that close compromises your claim against hollow tiles, hairline cracks, and finishing defects that surface under use.

Bookmark your reference number. Take a final round of photos at the end of day one, before you leave. Save them with date metadata intact. They are your independent record of unit condition at acceptance.

What this article does not cover

The technical depth of each defect category (hollow tile detection, drainage gradient testing, RCD trip verification, bomb shelter compliance) lives in the Toolkit and the common defects catalogue.
