How many pool quotes should I get before deciding?

How many pool quotes should I get before deciding?

Three written quotes, on the same plans and specifications. That is where the three regulators we read land, in slightly different words:

• NSW Fair Trading, on building a pool: “Gain quotes from at least three builders.”
• Consumer Affairs Victoria, on getting quotes: do not lock yourself into a contract until you have compared at least three quotes for the same plans and specifications, and “compare at least three written quotes and analyse them thoroughly”.
• The QBCC in Queensland: “we always recommend getting more than one quote”.

Three works for a reason that is about arithmetic rather than tradition. With one quote you have a price and nothing to compare it to. With two you have a gap, but no way to tell which of the two is unusual. With three, a single quote that stands apart from the other two is visible as the one that needs explaining.

The three-quote stopping rule: get three written pool quotes on the same scope, and stop there unless one of them stands alone.

Where to find the builders and what to send them is covered in getting free pool quotes; this page is only about how many and when to stop. If you are pricing a small pool, comparing plunge pool quotes covers the lines specific to that job.

When are two pool quotes enough?

Two pool quotes are enough only as a floor, when a third licensed builder genuinely will not quote your site. That happens on remote blocks, very tight access, or in a peak season where builders are not taking new work.

Two meets the QBCC's minimum of more than one quote, but it is below the three that NSW Fair Trading and Consumer Affairs Victoria both name. The weakness is structural: if the two quotes are $15,000 apart, you cannot tell from the numbers alone whether the high one is padded or the low one has left something out.

If you are stuck at two, make each one do more work:

• Ask both builders for a written exclusions list, so the gap between them can be traced to named lines.
• Ask both how rock and excess soil are priced. The QBCC notes that spoil removal “can be an expensive addition” and says to check who is responsible for it.
• Use a published range as a sanity check, not a third quote. What a pool costs in Australia sets out the published ranges and says who publishes them.

Two pool quotes tell you there is a difference; only a third tells you which quote is the unusual one.

When does a fourth pool quote change nothing?

A fourth pool quote changes nothing when the first three priced the same scope and none of them stands alone. A fourth price in that situation lands inside the range the three have already set, and the time spent getting it is time the approval clock is not running.

There are two situations that look as if they need a fourth quote but do not:

• The three disagree about the ground. One allows for rock, one excludes it, one is silent. Another builder will simply make a fourth assumption. The QBCC's guidance is that a builder must provide a soil test and contour survey, unless you already have one, to justify earthworks and footings costs. Get the site information, then ask all three to re-price the same ground. See whether you need a soil test before building a pool.
• The three are for different pools. If one quotes a fibreglass shell with a barrier and another quotes concrete without one, you do not have three quotes; you have three designs. Fix the brief, not the count.

A fourth quote is worth getting in one case: one of the three stands alone, you have asked that builder to explain the difference line by line, and the scope does not explain it.

When pool quotes disagree about rock or access, the missing input is a soil test, not another builder.

What has to match before a pool quote counts toward the three

A quote only counts toward the three if it prices the same job as the other two. The regulators name the lines that most often differ:

That is the minimum for the count to mean anything. The full line-by-line comparison, with the wording that signals a line is missing, is in what differs between pool quotes, and the questions to put to each builder are in questions to ask a pool builder.

Three pool quotes for three different scopes are one comparison you have not made yet, three times over.

The low quote in the three: a question before it is a saving

When one of three quotes is much lower than the other two, the stopping rule says do not sign it and do not stop yet. Ask the builder to explain the difference in writing.

There is a Queensland reason to be careful beyond scope. The QBCC states that if you accept a quote that is below fair market value and need to make a claim under the Queensland Home Warranty Scheme, the amount of compensation you receive may be reduced. A low outlier can cost you at the moment you most need the insurance.

In New South Wales, check two things about every builder in the set, not just the cheapest:

• Licence: NSW Fair Trading states that if the work costs more than $5,000 the person or company must hold a licence issued by Building Commission NSW for building or swimming pool building. See how to check a pool builder's licence.
• Split contracts: NSW Fair Trading says to be wary of builders who use several different contracts under $20,000 for one job, because they may be avoiding Home Building Compensation Fund obligations. A quote broken into pieces is not cheaper; it is less insured.

Other signs worth a second look are in pool builder red flags. When you are ready to line up three quotes on the same brief, you can compare pool quotes from builders who cover your area, including Sydney, Brisbane and Melbourne.

In Queensland, a pool quote below fair market value can reduce what the home warranty scheme pays if you later need to claim.
