Victoria Contractor License Requirements: The $10,000 Line
Short answer: Victoria contractor license requirements are set by the Building and Plumbing Commission (BPC), which has traded under that name since 1 July 2025 in place of the Victorian Building Authority. Domestic building work worth $10,000 or more must be done under a written major domestic building contract with a registered building practitioner. Electrical and gasfitting work is licensed separately by Energy Safe Victoria at any value. Eligible work over $20,000 needs Home Warranty cover.
Victoria renamed its building regulator and replaced its home building insurance scheme within twelve months of each other, so much of what you find in search results is out of date. The registration body is the Building and Plumbing Commission, and the safety regulator for electrical and gas work is Energy Safe Victoria. Two separate money lines matter here — $10,000 for registration and the contract, $20,000 for insurance — and they are not the same line. The rules are structured differently again in New South Wales and Queensland: different regulators, different thresholds, different insurance.
Who issues contractor registration in Victoria?
The Building and Plumbing Commission, which has operated under that name since 1 July 2025. It brought registration, plumbing licensing, dispute resolution and domestic building insurance together under one regulator.
One detail is worth getting right, because it decides whether old paperwork is still valid. The BPC is not a brand-new legal entity that abolished its predecessor: the BPC’s own site identifies it as “Victorian Building Authority, trading as the Building and Plumbing Commission.” The VBA is the legal body; BPC is the name it now trades under. So a registration issued by the VBA did not evaporate — but the organisation you deal with, and the name on current guidance, is the BPC. Old vba.vic.gov.au links still resolve, which is why stale advice keeps circulating.
The legislation kept its names: the Building Act 1993 governs registration, the Domestic Building Contracts Act 1995 the contract itself, alongside the Building Regulations 2018.

What is the $10,000 threshold in Victoria?
When domestic building work reaches $10,000, two things happen at once: the work needs a registered building practitioner, and the parties need a written major domestic building contract. BPC’s guidance for homeowners puts it directly — for work worth $10,000 or more, “you must have a written contract with a registered builder.”
Treat exactly $10,000 as caught. BPC’s own pages word the boundary two ways: its contracts guidance says “$10,000 or more”, while its page on engaging a builder describes needing a registered builder “for work worth more than $10,000.” A job priced at precisely $10,000 sits in that gap, and the safe assumption is that both obligations apply.
The figure is the total value of the project, counting labour, materials and GST — a project figure, not an invoice figure. Splitting a $14,000 bathroom into two $7,000 invoices does not put you under the line.
Two related contract rules catch small operators out. Deposits are capped: never more than 10% if the total contract price is under $20,000, and never more than 5% if it is $20,000 or more. Asking for more is illegal under the Domestic Building Contracts Act 1995 — and taking illegal deposits is something the BPC actively prosecutes. Cost plus contracts are restricted: in Victoria they are only allowed for projects worth $1 million or more, so a cost plus arrangement on an ordinary domestic job is not available to you.
Which trades need a separate licence in Victoria?
Victoria’s mandatory credentials cluster in three places rather than spreading across a long list of individually licensed trade categories. Before assuming a given trade is unregulated, check it against the two regulators below — but these are where the requirements sit:
- Builders — registered by the BPC, in classes including domestic builder.
- Plumbers — licensed and registered by the BPC, and plumbing work is regulated regardless of the job’s value.
- Electricians and gasfitters — licensed by Energy Safe Victoria, a completely separate regulator with its own public register.
That last split is the one people get wrong. Energy Safe Victoria is the energy safety regulator for electricity, gas and pipelines, so contracting to do electrical work for payment runs through Energy Safe, not the BPC — and a BPC builder registration does not authorise you to do electrical work.
The practical read for a sole operator: general renovation under $10,000 may need no state registration at all, but the moment a job includes wiring, gas or plumbing, a separately credentialled person must do that portion, however far under $10,000 the total sits.
What happens if you work unregistered in Victoria?
Carrying out building work that requires registration without holding it is an offence under the Building Act 1993, and the BPC investigates and prosecutes. Victorian courts have convicted individuals and ordered payments well into the tens of thousands of dollars, including costs.
Quieter consequences hurt a small operator more than a fine:
- A homeowner using an unregistered builder has no protection from poor quality work, which is exactly the argument that surfaces when a job goes wrong.
- The work will not attract Home Warranty cover, removing the client’s protection and removing your standard answer to a defect claim.
- Prosecutions and disciplinary findings are published on the BPC’s prosecution and disciplinary register, where any future client can find them. Breaches of the Building Act 1993, the Building Regulations 2018 or the Domestic Building Contracts Act 1995 can all land there.
What insurance must a Victorian builder carry above $20,000?
This is the part of Victorian practice that changed most recently — on 1 July 2026, four weeks before this article was written.
Home Warranty started that day, applying to eligible domestic building work under eligible contracts signed on or after 1 July 2026, valued at more than $20,000. Maximum assistance is $400,000 in total per home, subject to eligibility, limits and exclusions, and the BPC provides it. Cover runs up to six years after completion for major defects — structural, waterproofing and weatherproofing — and up to two years for other defects or non-compliant work.
The design change is bigger than the numbers. DBI responded only where the builder died, disappeared or became insolvent. Home Warranty is not limited to those situations: it may respond where eligible work is incomplete, defective or non-compliant and the builder fails or refuses to complete or fix it. A client no longer waits for you to go under before claiming.
The transition trap is the one most likely to mislead you:
- DBI has not disappeared, and its numbers are not stale. Contracts signed before 1 July 2026 stay under Domestic Building Insurance, which was required for work valued over $16,000 and generally provided up to $300,000 of cover for homes up to three storeys. If you see $16,000 quoted, that is the live DBI figure for older contracts, not an out-of-date page.
- Cover does not roll over. A DBI certificate of insurance issued before 1 July 2026 continues under its own terms; it does not convert into Home Warranty. Which scheme applies turns on when the contract was signed, so check contract dates rather than assuming the newer scheme.
The two lines also create a middle band: a $15,000 kitchen needs a registered practitioner and a major domestic building contract, but sits below the Home Warranty threshold. Victoria’s insurance requirements covers that in detail.
How does a Victorian homeowner check a builder’s registration?
Two free registers, both worth checking before signing:
- Find and check a practitioner — the BPC register of registered building practitioners and licensed plumbers. Confirm the person’s name, their registration class, and that it is current.
- Prosecution and Disciplinary Register — shows whether a builder, plumber or building company has had disciplinary or prosecution action taken against them.
For electrical or gas work, search Energy Safe Victoria’s public register instead — a BPC search will not show an electrician’s licence.
Check the class, not just the presence of a record: a registration in one class does not authorise work in another, and a lapsed registration looks much like a current one on a business card.
What records does a registered Victorian builder need to keep?
Registration is the entry ticket. What keeps you registered and defensible is the paper trail: contracts, variations, progress claims, supplier invoices and the receipts behind every deduction you claim from the ATO and your state regulator.
That is where Keel fits, and it is worth being precise about what it is not. Keel is a record keeper, not a compliance tool: it will not apply for your BPC registration, arrange Home Warranty cover, or lodge anything with the ATO. It holds the evidence — invoices as PDFs with your own numbering, logo and a payment-link QR code; receipts captured and read on-device using Apple Intelligence; a mileage log; reports; an Accountant Pack; and an append-only hash-chained ledger, so the record cannot be quietly rewritten after the fact. A whole year exports as a single file.
It runs entirely on your iPhone — no account, no bank connection, no cloud sync — and its App Store privacy label is “Data Not Collected”. Free covers unlimited invoices, receipts and mileage at $0; Keel Pro is a one-time $249.99 Lifetime purchase, not a subscription. Estimates are in development and have not shipped. If you are deciding how long to hold everything, how long to keep tax records sets out the retention periods.
Frequently asked questions
Do I need registration for a job under $10,000 in Victoria?
Not for general domestic building work — the registered builder and written contract obligations attach at $10,000, counting labour, materials and GST across the whole project. But that figure does not apply to plumbing, electrical or gasfitting. Those need the relevant BPC or Energy Safe Victoria credential at any value, including a $200 job. Treat a job priced at exactly $10,000 as caught.
Is the VBA still the regulator in Victoria?
In substance it is the same body under a new name. The BPC’s own website identifies it as “Victorian Building Authority, trading as the Building and Plumbing Commission”, and it has traded as the BPC since 1 July 2025. So the VBA was not abolished and older VBA-issued registrations did not lapse, but current registration, plumbing licensing, dispute resolution and insurance all run through the BPC.
What is the difference between the $10,000 and $20,000 thresholds?
They do different jobs. At $10,000 you need to be a registered building practitioner and the parties need a written major domestic building contract. Above $20,000 an eligible project additionally needs Home Warranty cover. A job between the two figures needs registration and a contract but not the insurance, which is why the middle band catches people out.
Does Home Warranty replace my Domestic Building Insurance policy?
No. A DBI certificate of insurance issued before 1 July 2026 continues under its own terms and conditions — cover does not transfer across to Home Warranty. Which scheme applies to a given project depends on when the contract was signed, so a $16,000 threshold and $300,000 cover limit still govern older DBI contracts. Check contract dates rather than assuming the newer scheme applies.
Can I do electrical work if I hold a BPC builder registration?
No. Electrical and gasfitting licensing sits with Energy Safe Victoria, a separate regulator from the BPC, with its own public register. A BPC builder registration does not authorise electrical work at any value. You need to hold the Energy Safe credential yourself, or subcontract that portion to someone who does.
Does Victoria have a state sales tax I need to register for?
No. Australia has no state-level sales tax. The consumption tax on your services is GST — federal, administered by the ATO, and identical in every state and territory. What genuinely varies between Australian states is payroll tax, which is an employer tax, not something you add to a client’s invoice.
