What is the Security of Payments Act (NSW)?

In NSW the industry is regulated by the Building and Construction Industry Security of Payment Act 1999 NSW.The Act sets out the rules and procedures that professionals such as principals, head contractors, subcontractors and suppliers must adhere to when making payment, claiming payment or withholding payment.

The Act protects the rights of construction workers to receive progress payments for goods or services delivered and ensures that workers under a contract are entitled:

  • To receive and to recover, progress payments in relation to the carrying out of that work; and
  • The supplying of those goods and services.

Entitlement to payment

Under the Act, contractors are entitled to receive progress payments under any contract. This includes verbal, written contracts and absent contracts where the contract may stipulate that the contractor is not entitled to claim progress payments. These include independent contractor agreements which sets out the rights and obligations of each party.

Progress payments are calculated on the value of work or supplies that have been carried out or delivered and the terms of the contract. Where there is a dispute over the amount of a progress payment owed, contractors may choose to engage an arbitrator to help determine the dispute. Additionally, unless otherwise stated within the contract, any claim for progress payments can only be made once per month.

Payment claims

Where there is a progress payment owing for construction work and a claim has been made by the owed party, the Act has specific time limits for payment to be made:

  • Payment by principal to head contractor: 15 days after claim is made.
  • Payment by head contractor to subcontractor (non-residential): 30 days after claim is made.
  • Payment by head contractor to subcontractor (residential): 10 days after claim is made.

Payment schedule

If a person does not intend to pay the total amount claimed, they may provide a payment schedule within 10 days of the claim being made. A payment schedule is a notice in writing that must be served to the claimant to inform then the debtor does not intend to pay the amount claimed. The payment schedule must identify the payment amount being claimed and state reasons as to why the person proposes to pay less than the amount claimed.


If there is a dispute or unresolved conflict between the parties regarding the amount claimed, the claimant may initiate adjudication and engage the services of an adjudicator. The claimant must submit their notice of intention to apply for adjudication 20 days after the due date has passed.

Breach of the Act

The Building and Construction Industry Security of Payment Act protects the rights of contractors and suppliers under a construction contract to receive and recover progress payments for carrying out work and supplying related goods and services. There are severe financial and criminal penalties if the security payment laws are intentionally breached and enforcement action may be taken against the property of a debtor.
