How many electricians does Starworks rank in Castle Hill?

Starworks ranks 73 electricians in Castle Hill, NSW, holding 3,507 Google reviews between them. Across the 73 the median rating is 5.0 stars from a median of 19 reviews. Of the 73, 69 are rated 4.5 or better and 10 have passed 100 reviews.

What star rating should I expect from a good electrician in Castle Hill?

The median Google rating across the 73 electricians Starworks ranks in Castle Hill, NSW is 5.0 stars, and 69 of them sit at 4.5 or above. A rating at or near that median is ordinary for electricians in Castle Hill, NSW 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 electrician in Castle Hill have?

The median electrician Starworks ranks in Castle Hill, NSW carries 19 Google reviews, and 10 of the 73 electricians have passed 100.

How does Starworks rank electricians in Castle Hill?

Starworks gives every electrician in Castle Hill, NSW 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 electrician in Castle Hill 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 electrician with a handful of excellent reviews may still be the right choice in Castle Hill, NSW. The star rating and review count sit next to every score so you can weigh both yourself.

Why does the same electrician 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 50 distinct electricians in Castle Hill, NSW rather than a longer list of repeats.

How often is this list of electricians in Castle Hill updated?

This ranking of electricians in Castle Hill, NSW 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 electrician business ranking in Castle Hill?

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 electrician Starworks ranks in Castle Hill, NSW carries 19 Google reviews at 5.0 stars.
