New figures show the Building and Plumbing Commission (BPC) has significantly stepped up its enforcement efforts with many key areas reaching record highs.

In 2025-26, the BPC’s immediate suspension power, used only in the most serious cases and in the public interest, was exercised 24 times, a six-fold increase on the previous financial year.

A record $2.12 million in penalties was also handed out, a 55% increase on last year and more than double the number from 2 years ago.

In the same period, the BPC issued 103 suspensions, cancellations and disqualifications compared to 49 the previous year.

The BPC also boosted its efforts to hold unregistered and unlicensed practitioners to account for working without the required insurance and leaving homeowners unprotected.

Prosecutions, predominantly focused on this cohort, more than tripled with 68 matters finalised through the courts compared to 21 last year.

BPC inspectors also expanded their use of a power which compels building practitioners to rectify non-compliant work under construction.

The Direction to Fix power, which comes at no cost to consumers, was used 71 times compared to 12 last year.

More than 900 Rectification Notices were issued to plumbers to fix non-compliant work along with more than 5200 audits and drain inspections.

BPC Commissioner and CEO Anna Cronin says the data shows the regulator has pivoted to focus on protecting consumers. ‘We’ve increased the use of our full regulatory toolkit to address non-compliance, lift industry standards and improve consumer outcomes’, she said.

‘We know most builders do the right thing but those who don’t, can expect the BPC to act.’

Building and plumbing complaints have fallen by 21% and 10% respectively in the 2025-26 financial year, the lowest numbers in more than 5 years.

Ms Cronin says the drop in complaints could be attributed to the BPC’s establishment on 1 July 2025 bringing all domestic building functions under one roof. ‘Streamlining services makes it easier to access information sooner and helps consumers and practitioners more effectively navigate the building system.’

New powers introduced on 1 July 2026 have since strengthened the BPC’s ability to take targeted enforcement action, providing more options to address risks and better protect consumers.
