Security of payment  

There are payment requirements in the building and construction industry that principals, head contractors, subcontractors and suppliers must follow. These are regulated by the Building and Construction Industry Security of Payment Act 1999 (the Act).

All contractors providing goods or services as part of construction work have the right to receive ‘progress payments’ for work delivered. This section outlines the particular standards for these payments, which help to enable fair and timely remuneration for construction work.

The section also has information on how to make and respond to a payment claim, what to do if there is a dispute over a payment, how to apply for adjudication and key deadlines you must know to maintain the protections afforded to you and help you avoid costly legal proceedings.

What to do if you have not been paid 

There are two steps to take if you have not received a payment schedule within the required number of business days after making a claim, or you have not been paid by the due date.

Step 1: Ensure you have made a claim for payment

You can learn about how to do this on the Making a payment claim page.

Step 2: Apply for adjudication

Information about this step can be found on  the Applying for adjudication page.

You may also wish to obtain your own independent legal advice about commencing action in an appropriate court

Note - NSW Fair Trading does not recover money owed to a person by a head contractor.

Entitlement to progress payments 

Contractors have a right to progress payments:

  • whether a contract is verbal, written or absent, and
  • even if a contract states the contractor cannot claim progress payments.

Unless otherwise stated in the contract, progress payment claims can only be made once per month. The progress payment amount is calculated based on: 

  • the terms of the contract, or
  • the value of the work carried out (if not specified in the contract terms).

IMPORTANT: Be aware of time limits for making a progress payment claim (see our Summary of key deadlines below).

If there is a dispute over the amount of a progress payment owed, contractors can have an arbitrator determine the dispute, under certain conditions. Find out when and how to apply for adjudication, and essential steps to take to help you recover the adjudicated amount at the Applying for adjudication page on the Fair Trading website.

The Payment claim and adjudication flow chart on our website shows the payment claim and applying for adjudication processes.

Summary of key deadlines 

The tables below show the key deadlines as set out in the Act for making a payment claim, responding to a payment claim with a payment schedule, applying for adjudication and making a payment withholding request (refer to the relevant pages for full details).

Note that these deadlines are only the maximum timeframes as provided for by the Act if your contract does not specifically set out deadlines. Your contract can specify shorter deadlines, so you should always check your contract first.
