Kevin Patten
I recently returned to Voltaic Welshpool to have a few upgrades to my Landcruiser 200 series after a great experience having a new GME XRS-370C CB radio installed. This time had a Headlight upgrade, solar panel installed on rhino rack plus a Gator Dash Cam installed. From booking through Jaimee at reception to Max doing the installation the whole process was very friendly and professionally done. Great communication throughout the whole process delivered the end result being a very satisfied customer. I highly recommend the Voltaic team and also make mention of the great cooperation with the Elite Tune team who also did some great work at same time & place. Congrats to you guys.
Cheers Kevin Patten

Took in my first company ute for a mine and fitout. Great service, took their time, quality workmanship, explained everything and completed a good walk down after. Will use for each of my fit outs.

Highly recommend

Dion fitted dual battery, radio and power outlets for solar blanket and fridge to our Prado. Very happy with the professional service, discussion of options and fielding questions post installation. Thanks

I haven't had the pleasure of using Voltaic's services, but my review is solely based on my interaction with one of their staff.

Vince rang me to let me know that a courier dropped off a package for me. They had dropped it off to them instead of where my office was, a couple of buildings further up the road.

Vince was courteous, very professional and was happy to hold on to the parcel for me.

I was very impressed by Vince. His honesty, integrity and attitude to doing the right thing is truly admirable. If Vince exemplifies Voltaic's company philosophy and approach to interactions with the general public, I will definitely look to them to get work done on our fleet vehicles.
Shane Yaxley
Highly recommend this company there was no problems in squeezing us in before our Easter holiday. Kayne the technician working on our landcruiser was top notch,very informative and spot on with his diagnosis and phone manner was impeccable 👌
Stefan Lam
Booked in to have a chat with Kody, went through ideas and plans for a dual battery set up. He was very knowledgeable and had a a good plan on how to execute my idea.
When picking up the van the work done was everything we had discussed, the work done was spot on and to a high standard.
This is the second time going with Voltaic and will be back for more work in the future!

I've been coming here to Welshpool for a while now with my FJ Cruiser and i am really happy with them. A decent sized business, with a large staff, more than one shop and a highly professional and organised operation, yet still really friendly and interactive. They are not the cheapest mob in town, but their costs are fair and reflect in the quality of their work.
Today i saw Tara at the front desk who was lovely and very helpful, as well as knowledgeable and young fella Max, who is a rippa! See you next time. JT from Kalamunda.

I had a fantastic experience with Voltaic Auto Electrical!

Took my car to voltaic to get some aftermarket headlights installed. Anthony did a fantastic job with the install, knocking it off in less than a day. he called me halfway through the day to let me know the plan and was more than happy to walk me through the work that had been completed when i came to pick it up. Top bloke!
Jody Williams
Finding a trustworthy tradesperson can be daunting for me, but I couldn’t have felt more at ease. From the start, the team at Voltaic were prompt to reply, helpful, friendly, and completely upfront about costs—no hidden surprises or upselling. I never felt like a burden or that my questions weren’t valued. Their honesty and integrity truly stood out, and I’m grateful to have found a business I could rely on. Highly recommend!
Natalie Roberts
Staff were very friendly and helpful. Giving helpful suggestions and advice. Pleased with the work done.
Zyzz Reborn
A very very capable team of young lads who heavily focus on quality and presentation. You can openly communicate with the team and they will take everything you say to account. I will be recommending voltaic to my family and friends.
Alex Warren
After several bad experiences with a dealership (car under warranty) I decided to go elsewhere. Voltaic staff have customer service unparalleled. They went above and beyond researching different solutions (parts new, used, genuine and independently sourced) and gave me comfort and confidence that I was getting the best possible service and workmanship. Especially if you haven’t much car knowledge, I wholeheartedly recommend Voltaic. The technician fixing my car (James) brainstormed so many options for me until we found something that matched my budget and timeframe I needed my car back in. Genuine and trustworthy, James knows his stuff and is keen to help make a difference when he can.
Trent Little
Last minute urgent appointment to check out my electronic break system whilst driving through Perth. They fit me in and talked me through everything. Were very generous with their time and great customer service.
Kevin T.
I recently had my car's AC fixed at Voltaic, and I couldn't be happier with their service! From the moment I booked the appointment with Tara over the phone, everything was smooth and professional. She made the process easy and ensured all my questions were answered.

A big shoutout to Dion, the technician who worked on my BMW. Being a BMW owner himself, he not only repaired the AC efficiently but also kept me informed every step of the way. Dion went above and beyond by showing me the repair process at each stage, which really gave me confidence in their transparency and expertise.

It's refreshing to find a garage that prioritizes transparency, excellent communication, and high-quality workmanship.
Jaysin Hartmann
Thanks Anthony for the great work on the Cub Camper. Honest helpful value based service.
Vincent King

I had my Dmax in for a Starlink installation which included a more complex setup of an external router, external antenna, etc. Dion did an amazing job with the installation, going above and beyond with what was requested.

Dion and the Voltaic team have been incredibly accomodating, professional and have provided the best service that I’ve received when it comes to auto electrical installations.

Would happily recommend Voltaic, Dion and the team for any type of Starlink install and any auto electrical work. Thanks again!
Tania Ashby
Everyone at Voltaic were very friendly and very knowledgeable about the services I required. I was able to get in within a week of me calling up where i wouldn't have been able to get in until 2025 for the more commercialised companies like ironman 4x4 and TJM. I am very happy with the service they provided. I will be coming back for more work on our 4x4
Beverley Gangell
Highly recommend this company for all your auto electrical work. We had a great technician in Anthony he did an awesome job installing Starlink in our caravan.
Jake Staunton
I’ve had quite a few electrical jobs done on my car through Voltaic. They do a very good job. They are always friendly and happy to answer any questions you may have. I wouldn’t go anywhere else! Thanks guys
Daniel Ripp
I found Voltaic Auto Electrical after looking for a 12v system for my Ford Ranger over a year ago, i ended up going with one of the battery box setups as i don't require constant power in my tub. The service and quality I received on that initial job has guaranteed them a client for life. I will always go to Voltaic for all my auto electrical work and have been back for tail lights, rear lights, electrical tidying, and no doubt I will be back for more in the future.

Big thanks to the team at Voltaic.

They also have great merchandise.
Tina Lynne
Very happy with Voltaic Electrical, all staff very professional & efficient. Wouldn’t hesitate to recommend their work & advice they gave.

FAQs

What Is an alcohol interlock device?

An alcohol interlock is a breathalyser that’s fitted to a car or heavy vehicle. It stops the vehicle from starting if alcohol is detected in the driver’s system. While driving, random retests are required to ensure ongoing sobriety. All breath tests and tampering attempts are logged electronically.

Alcohol interlocks can be fitted:

  • Under WA’s Alcohol Interlock Scheme for drink-driving offences
  • Voluntarily by employers for safety in fleet and heavy vehicles
What is the WA Alcohol Interlock Scheme?

The Western Australia Alcohol Interlock Scheme is mandatory for drivers convicted of certain drink-driving offences. Under the scheme:

  • Only vehicles fitted with an approved alcohol interlock can be driven.
  • Compliance is monitored by regular breath tests and data downloads.

On successful program completion, Voltaic Auto Electrical can remove the device, and the Department of Transport will lift the condition from your licence.

 
How long does an alcohol interlock installation take?

Installation usually takes about 2 hours. Drop your car off at 8:30am and we’ll call you when it’s ready.

 
How long does servicing take?

Servicing is a quick, 15-minute drive-in, drive-out appointment.

Can I service my interlock at a different centre?

Yes, you can visit any accredited provider. Voltaic is fully accredited for servicing, even if we didn’t install your system.

After successfully completing the program, you can:

  • Book Voltaic to remove your interlock device
  • Receive formal notification from the Department of Transport
  • Have the interlock condition lifted from your licence
 
How long does it take to remove the device?

Alcohol interlock removal takes about 1 hour.
