Retention release games: getting your 5% back

Nobody loses money on the retention percentage. Five percent is five percent — you can price it, finance it, live with it. The money gets lost in the release clause: the paragraph that decides when the five percent comes back, written by the side holding it. A 5% retention released on schedule is a financing cost. A 5% retention tied to someone else's final certificate is a donation you haven't recognised yet.

Here's the honest test for any retention clause: can you name the calendar date, or the event within your own control, when each half of the money comes back? If the answer involves someone else's contract, someone else's discretion, or no date at all — that's the game, and it's being played on you.

How retention is supposed to work

The payer withholds a small slice of each progress payment as security for defects. Half comes back at practical completion of your works; the other half at the end of your defects liability period. It exists so there's something to fix defects with if you vanish — not to be the head contractor's cheapest working capital. On a well-drafted contract, the whole arrangement is boring. That's the goal.

The games

Game 1: head-contract linkage. "Retention shall be released upon release of retention under the Head Contract." Your money now waits on a contract you've never read, a certifier you've never met, and disputes you're not party to. This is a pay-when-paid clause wearing a disguise — and in jurisdictions where conditional payment provisions are void, the same statutes often catch it (New Zealand's Act says so explicitly).

Game 2: the wrong completion. Release tied to "practical completion of the Project" when your trade finished in month three of a two-year build. Your defects exposure ended long ago; your money is still on site. Release should key off your practical completion and your defects period.

Game 3: discretion dressed as process. "Retention may be released upon application" — may, upon whose satisfaction, decided when? Every soft word in a release clause is a month of float for the other side. You want shall, a named trigger, and a deadline: "shall be released within 10 business days of…"

Game 4: no deadline on the second half. The PC release is clear enough, but the defects-period half just… has no date attached to the mechanism. The defects period ends and nothing happens automatically. Two years later it's an awkward phone call about a project everyone's moved on from. Small amounts, multiplied across every job you've ever done.

Game 5: double security. Retention plus an unconditional bank guarantee for the same risk. Security should be one or the other (or a capped combination) — twice the security for the same defects exposure is just twice the leverage.

What the law protects, market by market

This is one area where the five markets genuinely diverge, so check yours:

New Zealand — the gold standard. Since the 2023 amendments (in force October 2023), retention money on commercial construction contracts is trust property by operation of law — the trust arises automatically whether or not the payer does anything, the money sits in a compliant account with per-subcontractor records, and if the payer collapses, the receiver or liquidator becomes trustee of your money rather than distributing it to their creditors. Better still, s 18I voids clauses that condition release on anything other than your own performance, and bans charging you fees for administering your own retention. Details in the NZ guide.

Western Australia. A retention trust scheme phased in under the 2021 Act: cash retention held on trust for contracts over $1 million from February 2023, extending to contracts over $20,000 from February 2024 — which is to say, effectively everyone. See the WA guide.

Queensland. Retention trust accounts apply where the project trust framework applies — government contracts from $1 million and private contracts from $10 million, with the broader rollout paused in early 2025. Coverage depends on your specific project; the QLD guide has the current picture.

Victoria. The April 2026 reforms added a statutory right to claim release of performance security — retention and bank guarantees — through the Act's payment-claim machinery, and its new unfair-time-bar mechanism (s 13A) explicitly covers security-release notices. A genuinely new lever; see the VIC guide.

US, UK, Canada, and elsewhere in Australia: mostly, the contract governs. Some US states cap public-works retainage percentages and some prompt-payment acts touch retention timing, but there's no general trust protection — which is exactly why the release wording matters most in these markets.

The asks

Before signing, in descending order of value:

1. Your milestones, not theirs. Release at your practical completion and your defects period end — named as such.
2. Deadlines with teeth. "Shall be released within 10 business days of [trigger]," both halves.
3. Cap it at 5%, and no retention on top of an unconditional bank guarantee.
4. Offer the swap. A retention bond or bank guarantee in place of cash retention protects your cash flow while giving them real security — a standard, reasonable trade.
5. Kill the head-contract linkage, citing the conditional-payment statute where you have one.

After signing: diarise both release dates the day you sign, invoice for release the day each trigger lands (in NZ and VIC the payment-claim machinery itself can carry the claim), and chase in writing — retention debts age badly and companies fold.

Price it like the loan it is

Retention is an interest-free loan from you to the party above you — so price it like one. On a $200,000 subcontract at 5%, you're lending $10,000. Released on schedule (say half at PC in month six, half after a 12-month defects period), that's roughly $10,000 out for an average of a year — call it $800–$1,200 of financing cost at working-capital rates, which belongs in your margin. Now re-run it with Game 2 in play: release tied to project completion adds a year, and a lazy final-release process adds another six months. The same clause now costs two to three times what you priced, on every job, forever. Two practical habits follow. First, put a line in your tender assumptions: "Pricing assumes retention released at subcontract PC and end of subcontract DLP respectively." It costs nothing and reframes any later argument. Second, track retention receivable as its own aging report — not buried in general debtors — because money nobody watches is money nobody chases, and retention is the most forgettable receivable in construction.

Find the games before you sign

The release clause is three sentences buried in a payment section nobody reads twice. ContractorCounter Review reads it every time — flagging head-contract linkage, discretionary wording, missing deadlines, and oversized percentages, alongside the time bars and payment terms that compound them. US$19 per contract, findings shown before you pay, and the full checklist covers the rest of the payment section while it's at it.
