The certificates that block handover

You can't hand over, occupy or sell until a list of certificates is complete — and each one needs a booking, a specialist and lead time. Build that list in the last week and the handover stalls, the final payment waits, and the delay sits on your programme.

What YPA does

Builds the certificate list from your contract and the job — what's needed, who issues it, what it blocks — from early in the project, not the week before handover.
Dates every certificate backwards from occupation or handover, so the electrician, engineer and specialists are booked inside their lead times — not after them, when they're already busy.
Tells you in the morning brief what's due in the coming weeks — "CoC not yet booked" — while there's still time to fix it, not when the inspection is days away.
Files each certificate the day it lands and updates the list, so at the final inspection "is the list complete?" is a check, not a discovery.
Re-times the list if a date moves — if handover slips, every dependent certificate moves with it, and you're told what that means, instead of finding out on the day.

Why certificates become the blocker

You can't occupy, sell, hand over or get the final sign-off without the statutory certificates. The work can be perfect — but if the paperwork isn't there, the building stays locked, and the delay lands on whoever needed it done.

The frustrating part: most of these certificates take time to organise, and they're only needed at the very end. So they're booked last, discovered missing last, and the snag list becomes a waiting list.

The certificates that matter

The electrical CoC (Certificate of Compliance) — required for electrical installations, issued by a registered electrical contractor or person. A CoC without proper testing, or from an unregistered person, is a risk — not closure. The test report goes with it.
The engineer's certificate — where structural work or special conditions require it, confirming the work was done to the design.
Drainage / plumbing certificates — where the municipality or the contract requires them.
Other professional certificates — glazing, roof, fire — depending on the building and the local requirements.
Municipal occupation approval — the sign-off that lets people move in.

Exactly which ones apply depends on the building and the municipality. The list is never the same on two jobs.

When the missing CoC really hurts

Occupation can be blocked — nobody moves in.
Sale and transfer can be blocked — the new owner's bank wants it.
Handover drags — the client won't sign off, and the defects clock doesn't start until practical completion is real.

What a YPA sheet looks like

Every certificate goes onto the YPA Certificate Tracker — one row per certificate, with what it's for, who issues it, and when it's due. This is the actual sheet format YPA generates (filled with example rows):

What to do about it

Start the certificate tracker early — at the start of the job, not the week before occupation. Note what's needed, who issues it, and when it's due.
Book the specialists with enough lead time — registered electricians and engineers get busy in the last month of every job.
Check registrations — the CoC must come from someone properly registered. A questionable CoC is a liability, not a tick.
File them as they arrive — the day a certificate lands, it goes on the file. Losing it at handover is the same as never having it.

Want the full picture?

We've built YPA for the way African construction projects actually work. YPA is the site file with a memory. YPA is onboarding its first live builds in small, limited cohorts. Pilot places are free for a defined period — and if we ever charge, the plan and its price will be shown to you before anything is billed.
