What star rating should I expect from a good quantity surveyor in Perth?
The median Google rating across the 8 quantity surveyors Starworks ranks in Perth, WA is 5.0 stars, and all of them sit at 4.5 or above. A rating at or near that median is ordinary for quantity surveyors in Perth, WA rather than a warning sign on its own, and a rating well above it only means much when enough reviews stand behind it.
How many Google reviews does an established quantity surveyor in Perth have?
The median quantity surveyor Starworks ranks in Perth, WA carries 2 Google reviews.
How does Starworks rank quantity surveyors in Perth?
Starworks gives every quantity surveyor in Perth, WA a reputation score out of 100 from three things: its Google star rating (up to 47 points), how many reviews back that rating (up to 35), and whether customers can reach it by website and phone number (up to 18). Review volume is the one part that can subtract: below 15 reviews it costs points, because a near-empty review record gives a stranger very little to go on. No score falls below 0 and placement cannot be bought. The score measures the strength of a business's public review record rather than the quality of its work, so it is worth reading the reviews as well, and every listing links to them on Google.
Why does a quantity surveyor in Perth with all 5-star reviews score lower than one with a lower rating?
Because review volume counts as well as rating, and below 15 reviews it counts against you. Five perfect reviews are encouraging but thin evidence; three hundred reviews averaging 4.7 tell a stranger far more about what to expect on the day. That is a judgement about how much proof exists, not about the quality of the work, and a newer quantity surveyor with a handful of excellent reviews may still be the right choice in Perth, WA. The star rating and review count sit next to every score so you can weigh both yourself.
Why does the same quantity surveyor not appear several times on this list?
Some businesses run more than one Google listing, often one per suburb they service. Those are the same company, so Starworks groups them and shows the business once, using the listing with the strongest review record. That is why this page opens with 8 distinct quantity surveyors in Perth, WA rather than a longer list of repeats.
How often is this list of quantity surveyors in Perth updated?
This ranking of quantity surveyors in Perth, WA rebuilds on a 30-day cycle and prints the date of its last rebuild above the list, which for the current version is October 2026. Ratings and review counts are re-read from Google over time rather than on a fixed schedule, so an individual figure here can be older than the rebuild date.
How can I improve my quantity surveyor business ranking in Perth?
Collect genuine customer reviews consistently, and keep a working website and phone number on your Google listing, because those are the three inputs the score reads. There is no placement to buy on this page. For scale: the median quantity surveyor Starworks ranks in Perth, WA carries 2 Google reviews at 5.0 stars.
