How does the Security of Payment Act work in the ACT?
Last reviewed July 5, 2026
The Security of Payment Act in the ACT allows contractors and subcontractors to claim progress payments for work completed. If a payment's disputed, you can issue a payment claim. The principal must respond within a set time. If they don't pay, you can go for adjudication.
Key points
- Claims must be in writing.
- Respondents have 10 business days to reply.
- You can seek adjudication for unpaid claims.
This Act helps keep cash flow steady in construction. Follow the right process for claims and responses, or you might lose your right to payment. Keep records of all communications and submissions related to your claims.
