How to Choose a Pool Builder in QLD: Licence & Contract Guide

Learning how to choose a pool builder comes down to two checks most buyers skip: is the licence real and current, and does the contract lock a fixed price to a fixed scope. Get those right and the rest — design, shell colour, coping — is the fun part. Get them wrong and you can be $30,000 in with a half-dug hole and a builder who has stopped answering the phone. We install fibreglass pools across Brisbane, the Gold Coast, the Sunshine Coast and Ipswich, so the advice below is what we'd tell a friend buying anywhere in South East Queensland.

What does a pool builder do?

A pool builder manages the entire installation from council approval to handover, not just the day the shell drops in. On a fibreglass job that covers a defined sequence of work.

Building approval and, where required, engineering and plumbing/electrical certification
Setting out, excavation, and preparing a level, engineered base
Craning the shell into position and levelling it to tolerance
Backfilling, plumbing the filtration, and pouring the bond beam
Concrete surrounds or paving, fencing coordination, and the final safety certificate

Some outfits install pools alongside decks, sheds and extensions. A specialist installs pools and nothing else, which usually shows in the finish. When we crane a shell onto a sloping block, the levelling and backfill are where experience earns its keep — a generalist doing two pools a year is guessing at what a specialist does weekly. You can see the range of blocks and finishes on our completed pool installations.

Check the QBCC licence before anything else

Any business building a pool in Queensland must hold a current QBCC licence for that class of work — verifying it is the single most important step, and it takes about two minutes. The Queensland Building and Construction Commission runs a free online licence register.

Here's the walkthrough:

Go to the QBCC website and open the licence search ("Find a local contractor" / online licence search).
Search by the company's licence number or exact business name. A legitimate builder puts their QBCC number on their website, quotes and vehicles.
Confirm the licence is current, not suspended or expired.
Confirm the licence class covers swimming pool construction — a licence to do minor work or a different trade doesn't cover a pool.
Check the record for any history of directors moving between deregistered companies, which can signal a "phoenix" operator.

While you're there, confirm the job will be covered by the Queensland Home Warranty Scheme. In Queensland, residential construction work valued over $3,300 requires the builder to pay a home warranty insurance premium — you should receive a certificate of insurance before work starts. That cover protects your deposit and progress payments if the builder fails to finish or the work is defective.

For context on where we sit, our team has been installing pools in the region for over 25 years and holds QBCC licence 1315036 (and NSW Lic. 300188C). You can read more about the people behind the pool builder on our team page.

Red flags worth walking away from

Most bad pool jobs show warning signs before the contract is signed — these are the ones we'd treat as deal-breakers.

No QBCC number on any paperwork, or a number that doesn't match the register.
A large deposit demanded up front. In Queensland, contract law caps the deposit on most domestic building work; a builder asking for 30–50% before excavation is a problem.
Cash discounts to skip a written contract. A verbal deal has no home warranty cover and no legal protection.
A quote that's vastly cheaper than everyone else's. It usually means excavation, rock, or site costs have been left out and will reappear as "variations" once you're committed.
Vague inclusions — "pool and surrounds" with no itemisation of what surrounds means.
No fixed completion date or an unwillingness to put timeframes in writing.
Pressure to sign today to "lock in this price". A real price holds long enough for you to read the document.

What a fixed-price pool contract must include

A fixed-price contract should tie a single, itemised price to a defined scope so there are no surprises mid-build. Before you sign, check that every row below is present and specific.

Contract element	What good looks like
Fixed contract price	One total, with GST shown, not a "from" figure
Itemised inclusions	Shell model and size, excavation, backfill, filtration, coping, fencing scope
Allowances stated	Any provisional sum (e.g. rock removal) shown as a named allowance, not hidden
Payment schedule	Progress payments tied to completed stages, not calendar dates
Deposit	Within the Queensland legal cap for the contract value
Start and completion dates	Actual dates or a defined number of working days
Variations process	How changes are priced and approved in writing before work proceeds
Site conditions	Who carries the risk for rock, sand, water table or access issues
QBCC home warranty	Certificate of insurance provided before work begins
Warranty terms	Structural warranty on the shell plus workmanship on the install

The two rows people gloss over are allowances and variations. A cheap headline price often leans on a low rock allowance; when the excavator hits sandstone, the difference lands on you. Read how the money maps to real stages before you sign — our own pool building process lays out each stage and what triggers each payment.

Questions to ask before you sign

Ask these directly and listen for specific, confident answers rather than deflection.

How many fibreglass pools do you install a year, and can I see three recent local ones?
What's your QBCC licence number? (Then verify it yourself.)
What does your quote assume about my site — soil type, rock, access, fall?
What happens to the price if the ground is worse than expected?
Who does the safety-barrier certification, and is it in the price?
What's the structural warranty on the shell, and what voids it?
Can I speak to a customer whose pool you finished last month?

Pool fencing and barrier compliance is non-negotiable in Queensland and worth understanding before you commit — the rules are covered in our guide to pool safety regulations in Queensland.

Choosing well isn't about finding the cheapest number. It's about confirming the licence is real, the contract is fixed to a clear scope, and the builder has installed enough pools in conditions like yours to price the job honestly the first time.

FAQs

How do I check a pool builder's licence in QLD?

Use the QBCC's free online licence register. Search by the builder's licence number or business name, then confirm the licence is current and that its class covers swimming pool construction. Also check the record for a history of failed companies linked to the same directors.

Do you need a licence to build a pool in Queensland?

Yes. Any business carrying out swimming pool construction valued above the QBCC threshold must hold a current QBCC contractor licence for that class of work. Work over $3,300 also requires Queensland Home Warranty Scheme insurance, with the premium paid by the builder.

What should a fixed-price pool contract include?

A single itemised total (GST shown), the shell model and size, excavation and backfill, a payment schedule tied to completed stages, start and completion dates, a written variations process, stated allowances for site risks like rock, the home warranty certificate, and clear warranty terms.

How big a deposit should a pool builder ask for?

Only as much as Queensland's domestic building contract rules allow for the contract value. A builder demanding 30–50% before excavation, or offering a cash discount to skip a written contract, is a red flag — a compliant deposit keeps your money protected under the home warranty scheme.

How many years' experience should a pool builder have?

There's no legal minimum beyond holding the licence, but experience shows in the finish, especially on difficult blocks. Look for a specialist installing pools regularly rather than a generalist doing a handful a year, and ask to see recent local installs.
