How do I choose the right builder for a first home?

Your builder is the single biggest decision you make when building, bigger than the design or the block, because they control the cost, the quality and the timeline. The good news is that choosing well is mostly about doing a few sensible checks rather than relying on a good feeling. Here is what to look for.

Check they are properly licensed

Start with the basics: confirm the builder holds a current licence in the right category for your build. Every state has a public building register where you can check a builder licence and its status. An unlicensed builder, or one whose licence does not cover your type of work, is a hard stop, no matter how good the price looks.

Check the mandatory warranty insurance

By law, for residential work above a threshold, your builder must take out builder warranty or indemnity insurance in your name, which protects you if they die, disappear or become insolvent before finishing. If a builder tells you it is not needed when your build is clearly above the threshold, treat that as a serious warning sign. A builder who cannot obtain this cover may be uninsurable for a reason.

Look at their track record

A builder history tells you a lot. Look at homes they have actually completed, ask for and follow up references from recent clients, check how long they have been operating, and look for signs of financial stability. A builder with a solid, verifiable track record over time is a safer bet than a new or thinly documented one, however polished the sales pitch.

Read the fixed price contract and inclusions

Before you commit, read the fixed price contract and the inclusions list closely. Understand exactly what is included and what is not, how variations are handled, and how large the provisional sums are. The difference between builders is often not the headline price but what sits inside the contract, so compare on a like for like basis.

Be wary of the cheapest quote

The lowest quote is not the best builder. A low headline price can hide thin allowances and large provisional sums that come back to you later, or it can mean you are not comparing like with like. Be especially careful of a price that looks too good, and ask what is excluded, because that is usually where the gap is.

Display homes versus your build

Display homes are designed to impress and are often loaded with upgrades that are not in the standard inclusions. Do not assume your build will look like the display. Ask specifically what is standard versus an upgrade, so the home you actually get matches your expectation and your budget.

Communication and process

How a builder communicates before you sign is a good preview of the build itself. Are they responsive, clear about their process, and upfront about how they handle variations and delays? A builder who is hard to pin down during the sales stage rarely gets easier once construction starts.

Questions worth asking

A few direct questions sort the strong builders from the rest.

• Are you licensed for this type of work, and what is your licence number?
• Do you provide the mandatory builder warranty insurance?
• Is this a genuine fixed price contract, and what is excluded?
• How are variations and provisional sums priced and approved?
• Can I see completed homes and speak to recent clients?
• What is a realistic timeline, and how do you handle delays?

Why the builder choice protects your finance too

Choosing a sound builder is not just about the build, it helps your finance. Lenders are more comfortable, valuations on completion tend to be stronger when the builder has solid local comparables, and progress payments run more smoothly. So a careful builder choice protects your loan as well as your home, which is covered further in our guides on contracts and builder risk.
