Retention Release in Construction
Retention release is when withheld retention money gets paid back, usually in stages: part at practical completion, the rest once defects are fixed. Here is when it lands.
Definition
Retention release in construction is the point where money held back from your payments finally comes back to you. It is the unlock, not a new payment.
Retention is usually released in two stages. Part is released at practical completion. The balance is released once the defects liability period ends and any open defects are resolved.
Why it matters
For subbies, this is your money sitting on someone else's books for months. You did the work early in the build, but the retained slice does not come back until the whole job hits completion and the defects clock runs out. That gap can stretch past a year. Knowing exactly when release is due, and what has to be true for it to happen, is how you chase it without guessing.
How it works in practice
Retention is withheld bit by bit, taken from each payment as the job runs. Release works the other way: it comes back in chunks once the build is far enough along.
First chunk: practical completion. When the build reaches practical completion, the first portion of retention is usually released. A common split is half now, half later, though your contract sets the actual terms.
Second chunk: end of the defects liability period. The balance is released once that window closes and once any defects raised during it are fixed. Open defects stall the release until they are resolved.
One level up, builders hold retention from subbies for the same reason owners hold it from builders. So your release can be tied to the head contract's completion and defects window, not just your own finish date. That is why early-stage trades tend to wait longest.
Common misconceptions
Retention releases automatically on a date
It does not. The defects liability period ending is one trigger, but open defects can hold the money back until they are rectified. No fix, no release.
Release is a bonus payment on top
No. It is your own money coming back, the slice that was withheld from earlier payments. You already earned it.
Practical completion means you get all of it
Usually only the first portion lands at practical completion. The rest waits for the defects liability period to close and any open defects to be fixed.
If the builder goes broke, retention is safe
Not in the standard setup. Retention withheld up the chain often sits in a general operating account, so it can rank as an unsecured debt if the business fails. Where it lands then is a legal question for your lawyer or your state tribunal.
BuildFair holds withheld amounts in the regulated project account and releases them after completion once defects are resolved, with custody held by BuildFair banking partner Kobble (Kobble operates under AFSL 545391, Yondr Money Pty Ltd).
