Variation Not Approved — What Subcontractors Can Do Right Now

You have submitted a variation. The builder has gone silent. Three weeks have passed. The work is either already done or about to start. You are not sure whether the variation is approved, rejected, or still under review.

This is the most common commercial pattern in Australian subbie work. Here is the playbook.

The scenario

A $4,200 variation was submitted to your head contractor on the 28th of March. You followed up on the 4th of April — no response. You followed up again on the 11th of April — no response. The work is starting on Monday whether the variation is approved or not, because the head contractor's program demands it.

What you do next determines whether you get paid for the variation or absorb the cost.

Step 1: document the variation properly — right now

Before you take any further action, make sure your variation submission is bulletproof. The submission must contain:

• A clear scope description. What is the variation, where on site, what trade, what materials, what days.
• A cost breakdown. Labour hours × rate, materials at supplier quotes, any overhead. Not a single lump sum.
• A reference to the contract clause that triggers the variation. "Scope inclusions" or "scope exclusions" or "specification change" — whichever applies.
• The trigger event. Site instruction, RFI response, builder email, design change. Attach the document.
• A start date and a duration.
• Photos of the affected work or condition. Timestamped.

If your submission is missing any of these, the head contractor has cover for delaying their response. Tighten the submission first.

Step 2: send a formal follow-up notice

Email the head contractor's project manager. Copy their commercial manager and your director. Use this structure:

Re: Variation V-031 — Submitted 28 March 2026

>

Dear [PM],

>

We refer to our variation submission V-031 of 28 March (attached) and our follow-up emails of 4 April and 11 April.

>

The works covered by this variation are scheduled to commence on [date]. Without your written acceptance prior to commencement, the works will proceed as a directed variation under the contract.

>

Please confirm in writing your acceptance of the variation, or alternatively your written direction not to proceed, by close of business [date + 3 working days].

>

We expressly reserve all rights under the contract.

>

Regards,
[Name]

This email is the most important piece of paper in the chain. It does three things: forces a written response, names the date the works start, and reserves your rights.

Step 3: timeline of recommended actions

When	Action
Day of submission	Variation submitted with full breakdown + clause reference + supporting docs
Day 3	Follow-up email if no acknowledgment
Day 7	Second follow-up email
Day 10	Formal follow-up notice (the email above)
Day 13	If no response and works are about to start: proceed and document everything
Day 14 onward	Capture every site instruction, every email, every photograph that shows the works being performed
Day 30	Lodge the variation as a "directed variation" in your next progress claim if still no written response

Step 4: when the head contractor does respond

If they respond with a partial approval, accept the partial in writing and request written confirmation that the remaining items are deferred — not rejected.

If they respond with a rejection, you have three options:

1. Accept the rejection. Walk away from the cost. Sometimes the right call. 2. Push back with clause references. "We do not accept the rejection on those grounds. Refer Clause X..." Reuse the Back Charge Dispute Template structure. 3. Escalate. Refer to the contract's dispute resolution clause. Most Australian commercial contracts require notice within 14 days of the rejection.

If they respond with silence — that is, no response after the formal notice — you proceed and lodge the variation in your next progress claim with the chain of correspondence as evidence.

Step 5: what records you need before lodging

When the variation eventually gets disputed (and they often do), you will need:

• The original variation submission with breakdown and clause reference
• The supporting documents (RFI, site instruction, builder email)
• Every follow-up email
• The formal notice
• Site photographs with timestamps showing the work being performed
• Daily site reports referencing the variation
• Any verbal direction recorded as a written file note within 24 hours

Keep all of this in one folder per variation. When you make the claim, attach the lot.

What this looks like inside TradeControl

TradeControl tracks every variation from logged → submitted → approved automatically. Each variation has its own evidence chain — the original event, all related correspondence, photos, supporting clauses. When you lodge the claim, every record is one tap away.

If a builder rejects a variation, the Builder Response Analyser tells you whether the rejection is defensible against your contract — usually in under a minute.
