Letter of demand template for subcontractors: unpaid progress payments

When a progress payment is overdue, the first formal step is a clear letter of demand: the amount, why it is legally due, a short deadline and what you will do if it is not paid. Under the Security of Payment Acts, an amount the builder scheduled and didn't pay, or a claim it never answered with a payment schedule, is generally a debt you can recover, and in most states you can suspend work on notice.

When to use it
  • A scheduled or certified amount has passed its due date unpaid
  • The builder didn't serve a payment schedule in time and hasn't paid the claim
  • Calls and emails about the payment have been ignored
In the Word and PDF: The letter of demand; A table of the overdue amounts and due dates; Optional paragraph giving notice of intention to suspend work. Every [placeholder] is highlighted so nothing gets missed.

LETTER OF DEMAND

[Subcontractor company name, ABN]
Date: [date]
To: [respondent legal entity, ABN]
Attention: [director / contract administrator]
Contract: [subcontract title / number]
Project: [project name / site address]

Overdue payment: $[total amount] (including GST)

The following amounts are due and unpaid under the subcontract:

Payment claim | Date served | Amount due | Due date | Paid
[No. X] | [date] | $[amount] | [date] | [$0 / $part]
[No. Y] | [date] | $[amount] | [date] | [$0 / $part]

[Choose one:]
[The amounts above were set out in your payment schedule(s) dated [date] and were not paid by the due date.]
[No payment schedule was served within the time required by the Building Industry Fairness (Security of Payment) Act 2017 (QLD), so the full claimed amount is due and payable.]

We demand payment of $[total amount] in full by [date, e.g. 5 business days from this letter], into the account below.

Account name: [name]
BSB: [BSB]  Account: [account number]

If payment is not received by that date, we intend without further notice to take one or more of the following steps, as the Building Industry Fairness (Security of Payment) Act 2017 (QLD) and the subcontract allow:
- recover the unpaid amount as a debt due, including in court;
- apply for adjudication of the amount;
- suspend work under the subcontract after giving the notice the Act requires;
- claim interest at the rate the subcontract or the Act provides.

[OPTIONAL: This letter is also notice of our intention to suspend work under the Building Industry Fairness (Security of Payment) Act 2017 (QLD) if the amount is not paid within [the notice period under the Act] business days of receipt.]

Nothing in this letter waives any of our rights under the subcontract or at law.

Regards,
[name, position]
[company]

Template, not legal advice. Your contract's clauses and your state's Act govern. Check both (especially clause numbers, notice periods and service requirements) before this goes out on a real dispute.

Using it well

Say exactly why it is due
A demand is stronger when it states the legal basis in one line: the builder scheduled it and didn't pay, or never served a schedule at all. Delete the option that doesn't apply.
Only threaten what you will do
List the steps you are genuinely prepared to take, and take them on the date you set. A deadline that passes without consequence teaches the builder your letters can wait.
Suspension has its own notice
Most Acts let you suspend work for non-payment only after a written notice and a waiting period. If you might suspend, include the optional notice paragraph and check your state's period before you send.
The template protects the claim. The contract decides it.
Your notice windows, the clause numbers and whether the bar is absolute all live in your subcontract. The free scanner reads them in about two minutes, benchmarked against real Australian subcontracts.

Common questions

Do I need a lawyer to send a letter of demand?

No. A clear letter from your business is often enough to get an overdue progress payment moving. For large amounts, or if the builder disputes liability, get advice before you start court proceedings.

Can I charge interest on a late progress payment?

If the subcontract sets an interest rate on late payments, or your state's Act provides for interest on unpaid progress payments, yes. Check both and claim it in the letter.

Can I stop work if the builder doesn't pay?

In most states the Security of Payment Act lets you suspend work after a progress payment is overdue and you have given written notice of your intention. Stopping without following the Act and the contract can put you in breach, so follow the notice steps first.
