What is a registered builder?
If you're planning a renovation, extension or new home build, understanding builder registration is an important first step. In Victoria, a registered builder (also known as a registered building practitioner) has met the qualifications, competency and regulatory requirements to carry out specific types of domestic building work. Registration helps ensure builders meet professional standards and are accountable for complying with Victorian building regulations.
When do you need to use a registered builder?
For many residential projects in Victoria, you'll need to engage a registered builder to carry out eligible domestic building work. This typically applies to larger projects, such as home extensions, renovations, and new home builds, where registration is required under Victorian building regulations.
Using a registered builder provides greater confidence that your project will be completed by a qualified professional authorised to perform the work involved. It also helps ensure the correct building contracts, insurance requirements and regulatory obligations are met before construction begins.

Key benefits
- Registration helps you hire qualified, accountable building professionals.
- Consumer protections can reduce your risk throughout the building process.
- Public registration records make it easier to verify a builder before you hire.
You deal with a legitimate business
Hiring a registered builder gives you confidence that you're working with a business authorised to carry out eligible domestic building work in Victoria. Registration demonstrates that the builder has met the required standards and operates within the state's regulatory framework.
The builder has the right qualifications for the job
Registered builders must demonstrate the qualifications, skills and experience needed for the class of building work they perform. Choosing someone with the appropriate registration helps ensure your renovation, extension or new home is completed by a suitably qualified professional.
You receive better consumer protection
Registration supports important consumer safeguards, including compliance with Victorian building regulations and, where required, Domestic Building Insurance. These protections help provide greater accountability if issues arise during your project.
Registration details are easier to verify
Before signing a building contract, you can check a builder's registration details through the Building and Plumbing Commission's public register. This allows you to confirm their registration status, licence class and any publicly available disciplinary information before making your decision.
What are the risks of using an unregistered builder?
Choosing an unregistered builder can expose homeowners to unnecessary financial, legal and construction risks. While a lower quote may seem appealing, the long-term consequences of poor-quality work or non-compliant practices can far outweigh any initial savings. Understanding these risks can help you make a more informed decision before signing a building contract.
Poor workmanship
Unregistered builders may not have demonstrated the qualifications or competency required for the type of building work they're undertaking. This can increase the risk of defects, construction issues and work that doesn't meet the required building standards.
Incomplete building work
If an unregistered builder fails to finish your project, you could be left with an incomplete home extension or renovation and the added expense of finding another builder to complete the work. This often leads to unexpected delays and additional costs.
Non-compliant contracts and deposits
Building contracts must meet Victorian legal requirements, including rules around deposits and contractual obligations. If these requirements aren't followed, homeowners may have fewer protections and could face costly disputes during the project.
Limited recourse if something goes wrong
Resolving disputes can be more difficult when working with an unregistered builder. Depending on the circumstances, you may have limited access to the consumer protections, insurance requirements and regulatory processes that apply when engaging a registered building practitioner.

How to check whether a builder is registered
Before signing a building contract, take a few minutes to verify your builder's credentials. Checking their registration can help you confirm they're authorised to carry out the type of domestic building work you're planning and identify any issues before your project begins.
- 01
Visit the Building and Plumbing Commission website
Go to the Building and Plumbing Commission (BPC) website and open the public register. This is the official source for checking builder registration in Victoria.
- 02
Search for the builder or company
Enter the builder's name, registration number or business name to locate their registration details. Make sure you're checking the correct individual or company.
- 03
Confirm the registration details
Review the builder's registration status, registration class and the type of work they're authorised to carry out. Check that their registration covers the domestic building work you're planning.
- 04
Review disciplinary history
Where available, review any disciplinary findings or regulatory actions recorded on the register. This can provide additional insight into the builder's professional history.
- 05
Ask for supporting documentation
Request copies of relevant insurance certificates, licences and other documentation that support the builder's qualifications. A reputable builder should be happy to provide this information.
- 06
Compare reviews and past projects
Alongside checking registration, look at recent client reviews and examples of work the builder has completed. This gives you a better understanding of their workmanship, communication and overall reputation.
What else should you check before hiring a builder?
Verifying a builder's registration is an important first step, but it's not the only one. Before committing to a building contract, take the time to review the builder's qualifications, insurance and contract documentation. These checks can help you avoid unexpected costs, minimise risk and ensure your project complies with Victorian building requirements.
Registration class and licence details
Check that the builder's registration class matches your project, whether it's a renovation, extension or new home. A registered builder should be authorised to carry out the specific type of domestic building work you're engaging them to complete.
Domestic building insurance
For eligible projects, confirm that Domestic Building Insurance (DBI) will be provided before work begins. This insurance offers important protection in certain situations, such as if the builder dies, disappears or becomes insolvent before completing the project.
Contract terms and deposit requirements
Read your building contract carefully before signing. Make sure the scope of work, payment schedule, timelines and deposit requirements comply with Victorian regulations and accurately reflect what has been agreed.
References and completed projects
Ask to see examples of recent projects that are similar to yours and request references from previous clients. Speaking with past customers and reviewing completed work can give you greater confidence in the builder's workmanship, communication and reliability.
Choose a registered builder for peace of mind
A registered builder gives you greater confidence that your project will meet Victorian building standards. By checking their registration, insurance, and experience before work begins, you can reduce risk and make a more informed decision.
When you're ready to build, renovate or extend, choosing a registered builder is one of the smartest investments you can make.
