What to check before you book

Licences and accreditationsAsk which licence your job needs (it depends on the job and your state) and check the number with the body that issued it. Ask how your vehicle is insured while it's in their care.

Reviews and past workRead recent reviews and ask whether they often do jobs like yours, such as batteries or wiring faults.

A written quoteGet an itemised quote for parts and labour, and ask to be called before any extra work is done.

Local and availableA business based in or serving Thornleigh is easier to get to, and easier to go back to if something needs another look.

Getting started

Describe the job. Your vehicle's make, model and year, what's wrong or what it needs, and when you need it done.

Shortlist two or three. Use the filters above to narrow this page by listed credentials and website.

Compare quotes. Or send one request and we'll match it with up to 3 auto electricians.

Agree in writing. Confirm the price, what's included and when the vehicle will be ready before work begins.

Frequently asked questions

How do I choose between auto electricians in Thornleigh?

Compare two or three. Ask whether they work on your make, whether they can come to you, and for a written quote for parts and labour. A business that is owner verified on Mechanics Directory has confirmed it runs the listing.

How much does an auto electrician cost in Thornleigh?

It depends on the fault, how long it takes to trace, and the parts. Jobs like fitting a battery often have a set price, electrical faults are often charged by the hour, and a mobile call-out can cost extra. Asking two or three local auto electricians for a quote is the quickest way to see the going rate in Thornleigh.

Do auto electricians need to be licensed?

Anyone in any state who handles R134a, the air conditioning gas in many cars, needs a refrigerant handling licence from the Australian Refrigeration Council (ARC), and you can check a licence on ARC's website. Other auto-electrical work depends on the state. In New South Wales, a business that repairs vehicles needs a motor vehicle repairer licence from NSW Fair Trading, and the people doing the work generally need a tradesperson certificate (some minor work is exempt). You can check a licence on the NSW Government's online licence check. Listings marked "Credentials listed" show a licence, accreditation or membership on the business's profile. We don't check it, so confirm it with whoever issued it.

Who can regas my car's air conditioning?

For R134a, the gas in many cars, it must be someone with an automotive air conditioning licence from the Australian Refrigeration Council (ARC), and the business needs a refrigerant trading authorisation to buy and hold the gas. R1234yf, a newer car gas, isn't covered by the ARC licence. You can check a technician's licence on ARC's website.

What does "serves this area" mean?

Some businesses are based in a nearby suburb but cover this area, including mobile mechanics and towing services that come to you. On suburb pages we list businesses based in the suburb first, then the ones that say they serve it.

How do free quotes work?

Tell us about the job once. We match your request with up to 3 auto electricians near you. A business on a paid plan here gets it with your name and contact details and can contact you directly. A business on the free plan sees the job and your suburb but not your details, so it can't contact you unless it upgrades. A business that hasn't claimed its listing sees your request only once it claims. After you send, we tell you which applies to each business. It's free and there's no obligation.
