The complaints process

What happens after you make a complaint

After you lodge a complaint, BPC will acknowledge that it has been received.

Your complaint will then be queued for allocation to an assessing officer. Allocation timeframes vary depending on the number of complaints BPC is managing.

Once your complaint has been allocated and an initial assessment has been completed, the assessing officer may contact you to discuss the matter.

How BPC assesses building complaints

BPC may start an initial review of a building complaint if:

  • it involves a possible breach or offence under building legislation or regulations
  • it involves the conduct of a registered building practitioner
  • it involves building work carried out by an unregistered person
  • the matter is within BPC’s legal timeframes, which is generally within 10 years
  • where relevant, concerns have first been raised with the relevant building surveyor
  • there is enough information and evidence to support the complaint
  • building legislation also limits when prosecution action can be taken.

Complaints about building surveyors

The Code of Conduct for Building Surveyors requires building surveyors to:

  • communicate promptly and effectively with clients, BPC and other relevant parties
  • provide a clear complaint handling process
  • address non-compliance issues as soon as they are raised.

If your complaint relates to a building surveyor, include any information showing what steps you have taken to raise the issue and how the building surveyor responded.


How BPC uses your information

BPC may need to share your contact details and other relevant personal information with external parties when carrying out complaint-related functions.

For example, BPC may refer a complaint to the relevant building surveyor for the site so they can manage or resolve the issue.

You do not have to provide personal information. However, if you choose not to provide it, BPC may not be able to fully assess or respond to your complaint.

More information is available in BPC’s privacy policy.

How we handle your complaint

BPC assesses building and plumbing complaints under different laws. This means the process and possible outcomes may be different depending on whether your complaint is about building work, plumbing work, or practitioner conduct.

In all cases, BPC will review the information you provide and decide what action, if any, is appropriate.

We may:

  • ask you or another party for more information
  • review documents, photos, reports or certificates
  • seek technical advice
  • contact the relevant practitioner
  • refer the matter to the relevant building surveyor, local council or another agency
  • arrange an inspection, where appropriate
  • take regulatory action where needed.

The action BPC takes will depend on the issue, the evidence available, the level of risk, whether the matter is within BPC’s powers, and the conduct or history of the practitioner involved.

Building complaints

BPC may assess a building complaint where it relates to:

  • a possible breach of building legislation or regulations
  • the conduct of a registered building practitioner
  • building work carried out by an unregistered person
  • defective, incomplete or non-compliant building work
  • a matter that is within BPC’s legal timeframes
  • a matter where there is enough information or evidence to support assessment.

Where relevant, you may need to raise your concerns with the relevant building surveyor before BPC can progress the complaint.

If BPC identifies non-compliant building work that needs to be addressed, we may contact the relevant building surveyor, local council or other responsible party to support the appropriate action being taken.

If BPC identifies possible breaches or offences, we will consider the seriousness of the issue, the impact, the practitioner’s history and how the practitioner has responded to the complaint.

Depending on the circumstances, BPC may provide compliance advice, issue a notice or caution, seek an enforceable undertaking, refer the matter for investigation, or consider disciplinary action.

If the complaint raises an urgent life-safety concern, BPC may prioritise the matter. This may include referring the issue to the municipal building surveyor or arranging an inspection.

Plumbing complaints

BPC assesses complaints about plumbing work from consumers and other agencies.

Plumbing complaints may relate to:

  • plumbing work that does not comply with relevant laws, regulations or Australian standards
  • a failure to lodge or issue a compliance certificate where one was required
  • plumbing work carried out by a person who is not registered or licensed to do that work.

If a plumbing complaint is substantiated, BPC may expect the licensed plumber to return to the site, fix the issue and provide evidence that the work now complies.

If a compliance certificate was required but was not lodged or issued, BPC may require the plumber to lodge or issue the certificate. If a certificate needs to be corrected, BPC may require the plumber to correct it.

If BPC identifies possible breaches or offences, we will consider the seriousness of the issue, the impact, the practitioner’s history and how the practitioner has responded to the complaint.

Depending on the circumstances, BPC may provide compliance advice, issue a notice or caution, refer the matter for inspection or investigation, or consider disciplinary action.

Complaints about unregistered or unlicensed plumbing work may be referred for investigation if there is enough credible evidence and the matter is within the timeframe for prosecution.

If a plumbing complaint cannot be resolved

If BPC is not satisfied that the plumbing work has been brought into compliance, or a required compliance certificate has not been lodged or issued, the complaint may be referred for further inspection or investigation.

If BPC identifies a pattern of incompetence or negligence across multiple substantiated complaints, the plumber may also be referred for investigation.

Plumber insurance details

If you engaged a licensed or registered plumber and want to make a claim on their insurance, BPC may be able to give you the plumber’s insurance details.

You can request this information by emailing customerservice@bpc.vic.gov.au or calling 1300 067 088.

You may be able to make a claim on the plumber’s insurance if the work is within the insurance period and the plumber:

  • is no longer licensed
  • is unable to carry out the work
  • refuses to rectify defective plumbing work.

BPC can help you access insurance details in some circumstances, but BPC does not decide the outcome of an insurance claim.

If you are unhappy with the outcome of an insurance claim, you may need to apply to VCAT or seek legal advice.

Formal inquiry

If an investigation finds that a plumbing complaint is substantiated, the plumber may be referred to a formal inquiry.

A formal inquiry may result in:

  • a reprimand
  • a fine
  • a requirement to complete further training
  • suspension or cancellation of the plumber’s licence or registration.

Timeframes

Complaint timeframes vary. BPC cannot give a fixed timeframe for how long a complaint will take.

The time needed will depend on the complexity of the matter, the information available, whether technical advice is needed, and whether BPC needs information from other parties such as the relevant building surveyor, local council, practitioner or complainant.

BPC will contact you if more information is needed.

Behaviour when contacting BPC

BPC will handle your complaint respectfully and as efficiently as possible.

Our staff also have the right to end communication that is abusive, threatening, intimidating, harassing or disrespectful.
