Before Choosing a Builder: Key Checks

Choosing a builder is about more than liking a portfolio or receiving a competitive quote. You are deciding who may be responsible for turning detailed plans, substantial expenditure and months of decisions into a completed project.

Knowing how to choose a builder in Victoria therefore means checking both practical fit and verifiable information before committing.

The aim is not to find a builder who makes the biggest promises. It is to understand who you are dealing with, whether they are appropriately registered for the work, what their previous work demonstrates and whether their approach suits your project.

Confirm Exactly Who You Are Dealing With

Start with the basics.

Ask for the builder’s full business details rather than relying only on a trading name, social media profile or mobile number. Consumer Affairs Victoria recommends obtaining information such as the person’s full name, physical address, registered business name and relevant registration details.

You can also investigate how long a business has operated and whether it has previously traded under another name. Consumer Affairs Victoria identifies ASIC as a source for researching business history.

These checks help you understand the legal business or practitioner behind the quotation before you move further into the project.

Check Registration With the Official Source

Do not rely solely on a registration number printed on a website, vehicle, quotation or business card.

The Victorian Building and Plumbing Commission advises consumers to use its public practitioner search before appointing a builder or other registered building practitioner.

The search can help you confirm:

whether the practitioner is currently registered or licensed
the type of work they are authorised to undertake
whether conditions or limits apply to their registration
relevant registration or licence details.

The BPC specifically advises consumers not to rely only on advertising or information supplied by the practitioner when checking registration.

The important question is not simply, “Are they registered?” It is whether their current registration is appropriate for the work you are considering.

Look Beyond the Registration Check

Registration is an important check, but it should not be your only one.

The BPC also provides compliance and enforcement information that may include certain disciplinary actions, prosecutions, suspensions, cancellations or conditions. Not every complaint, enquiry or compliance activity necessarily appears there, so the register should be treated as one part of broader due diligence rather than a complete history of every customer interaction.

Consumer Affairs Victoria also recommends researching a prospective builder’s history and checking relevant disciplinary information before proceeding.

This is more reliable than making a decision from advertising claims alone.

Ask to See Relevant Previous Work

A polished gallery can show what a builder has worked on, but relevance matters.

If you are planning a substantial renovation, a custom home or another complex project, look for examples that help you understand the builder’s experience with comparable work. The projects do not have to be identical to yours, but they should give you something meaningful to assess.

Consumer Affairs Victoria recommends asking to see recent work and checking references from previous clients.

When speaking with a referee, go beyond asking whether they were “happy.”

Ask how the builder communicated, whether changes were documented, how unexpected issues were handled, whether progress updates were clear and whether the finished work matched what had been agreed.

Those questions reveal much more about the customer experience than a star rating alone.

Compare Quotes by Scope, Not Price Alone

The cheapest quotation is not automatically the best value, and the highest quotation is not automatically the most complete.

Before comparing prices, check that each builder has worked from the same plans and specifications wherever possible. Then examine inclusions, exclusions, allowances, fixtures, finishes and anything that remains to be confirmed.

Consumer Affairs Victoria recommends obtaining at least three written quotes based on the same plans and understanding exactly what each quotation covers. It notes that a lower quote may omit items or provide allowances that do not reflect the materials and finishes you actually want.

A useful comparison therefore asks, “What am I receiving for this amount?” rather than only, “Which number is lowest?”

Pay Attention to Communication Early

Building projects generate questions, selections, documentation and decisions. Communication is therefore part of the service, not an optional extra.

Notice what happens during the enquiry and quoting stages.

Are your questions answered clearly? Are limitations explained rather than avoided? Can the builder distinguish what is known now from what still needs to be investigated? Do written documents reflect what has been discussed?

Consumer Affairs Victoria specifically recommends considering whether a builder is likely to listen to your requirements, provide clear updates and communicate effectively both verbally and in writing.

Early communication cannot guarantee how an entire project will run, but it gives you useful information about whether the working relationship feels suitable.

Ask About Insurance and Required Documentation

Insurance requirements can depend on the type and circumstances of the work, so this is another area where assumptions should be avoided.

Consumer Affairs Victoria recommends asking to see appropriate evidence of public liability insurance. The BPC also advises checking whether the proposed work requires relevant insurance as part of your practitioner due diligence.

For domestic building work, use current Victorian government and BPC information when checking the insurance and documentation requirements applying to your particular project.

Do not rely on broad statements such as “fully insured” without understanding what cover is actually relevant.

Make Sure the Builder Fits Your Project

A capable builder may still be the wrong fit for a particular job.

Ask whether your project type, size, site, location and stage of planning suit the way the business operates. Find out what information they need before assessing the work and whether they can work from your existing plans or need other documentation first.

This is especially important for projects where design, engineering, surveying, permits or specialist consultants may be involved.

A good selection process is not about finding a business willing to say yes to everything. It is about establishing whether the builder’s actual scope and approach match what your project requires.

Do Your Checks Before You Commit

By the time you choose a builder, you should understand more than the quoted price.

You should know who the business is, whether the relevant registration checks out, what previous work and references tell you, what the quotation includes and whether the communication style gives you confidence that questions and changes can be dealt with clearly.

For homeowners, investors and suitable property owners considering a substantial project in Pakenham, Melbourne’s south-east or another confirmed SB Custom Homes service area, SB Custom Homes accepts project enquiries with details such as the property location, project type, plans or drawings where available, site information and intended requirements. Project suitability can then be considered against the scope, site and location rather than assumed from an initial enquiry alone.
