Great service, fixed horn in 75 series landcruiser which the manufacturer dealership did not want to know about. Up front with cost and keep you informed throughout repair work of any changes.
Excellent customer service, very friendly team. Would highly recommend Voltaic!!
Kayne and Max were so helpful in sorting my battery out as I was stranded in Perth and needed to get home

Thanks for the help you legends
I have been using the team at voltaic Joshua, Paul, Tara and Adam for several years now and the service and professionalism is at the highest level that I have seen. Not only does voltaic have experience in what they do, they are passionate about the industry in which they represent. There is a huge difference in that regard and I won’t use anyone else for my electrical and aircon needs 10/10
These guys (and gals) at Voltaic are seriously amazing. This is your old school customer sercice on steroids. We pulled in with our chevy and off road caravan thinking we would be asked to make an booking and come back which we could not do. We had an issue with our trailer brakes constantly disconnecting. They sorted it out for us right there and then. So happy ! Thank you very very much !
What a fabulous company! Their growth is definately for a reason and it has in no way changed the quality of service. Chipper is so helpful and Dion got the job done with a minimum of fuss. Kayne attended to several different vehicles in our fleet and deserves all the praise I can bestow. What a patient and professional young man. Took his time to explain and teach me about some basics. Was still mindful of timing so I was not overcharged. 10/10 recommend this company. I will most definately be using them in the future.
Can't possibly overstate the service and value for money. They completely undersold and over delivered! Great company, friendly, helpful, extra mile stuff. I will go to them first whenever I have a need in the future. Wish there were more stars.
Super friendly staff, great service and good quality work
I recently visited Voltaic in Welshpool to have a lightbar fitted to a company Toyota RAV4 Hybrid, and I couldn’t be more impressed with the service. From the moment I walked in, the atmosphere was welcoming — the staff are not only friendly and approachable, but it’s also great to see how well they interact with each other, creating a positive and professional vibe in the office.

The team are incredibly knowledgeable and take the time to clearly explain all your options, ensuring you feel confident about the work being done. They’re also very detail-oriented in their approach, which really shows in the quality of the finished job.

Despite the RAV4’s notoriously poor build quality at the front end — with flimsy plastics that could have made the install tricky — the Voltaic team handled it effortlessly. They cleverly mounted the bar behind the grille and secured it to the sturdier crash bar, making the install both neat and durable. This not only looks great but also keeps the lightbar safe from potential “carpark bandits.”

On top of their professional service, their pricing is very reasonable. The site even has a café and some comfy couches inside, which makes waiting around far more pleasant.

Voltaic are also fleet and mining certified, making them an easy recommendation for both individuals and businesses needing auto electrical or air-conditioning services.

Highly recommended — the team at Voltaic really make it a walk in the park, also Special shout out to Dion.
Service from the whole team was exceptional from the ladies at reception through to the technicians who fitted our dual battery system nothing was to much trouble and I am very satisfied with the finished job Thanks Team
It’s all about the Vibe.
When I walked into a showroom I felt the positive energy straight away.
The staff were super helpful and everyone working there looked happy and enjoying themselves.
You know if it’s a mechanical or electrical upgrade to your vehicle you just know that vibe/energy is going transfer into your pride and joy.
I highly recommend Voltaic Auto Electrical
I pick up my 79 series landcruiser yesterday. Kane worked on my vehicle, and I can say that he went above and beyond.He was professional with his workmanship and customer service,definitely a asset to Voltaic.
The work was neat and exactly how I wanted it. 100% I would recommend Voltaic. Thanks for doing such a awsome job Voltaic 👍👍👍👍👍
Excellent friendly staff
My experience with Voltiac was very positive. Their quote was fair and competitive. I got to speak to the electrician who did the job both at the start and at handover. I was able to ask all my questions. If the electrician was unsure about something he consulted with his colleagues. Everything was done as requested. Office staff were also very prompt and professional.
Very professional with a very high level of customer service
had a dual battery installed on my hilux, booking process was easy and quick reply’s going back and forth choosing a date etc. dealt with Kody (?) when i dropped the car off and the communication was thorough from that point until pickup. very neat work, highly recommend
I am really happy with the service at Voltaic.They squeezed me in without an appointment so that I was able to pick up my caravan. Anthony did such a great job, I felt confident in bringing my car back to get all the other electrical issues sorted. Everybody was so pleasant and couldn't do enough to help me out. Thanks everyone at Voltaic
Voltaic are really the go to people their services from the front counter to the workmanship is just top quality, the way the explain the works and keep you in the loop, can not recommend this business enough.
Great customer service kept me informed all 2 days, Kayne was great explained what was happening when I called in. Very happy with the service. Jamie was excellent in emails and calls prior to booking, and thanks for the care package, a nice touch.
Thoroughly recommend 👌
Great customer service and super knowledgeable team. Quoted accurately and everything went to plan and schedule. Anthony from their team was super comprehensive with everything and provided great solution options. Cheers guys
Great work from the team. They were all super polite, friendly and helpful. Had my UHF installed in my Jimny and Anthony was a great technician that made the process a breeze. Definitely would recommend.
Thank you ,Dion who repaired my electrical fault. it was so good to receive such excellent service . His efficiency and friendly nature was very much appreciated. I highly recommend Dion a top grade electrical mechanic. We could do with more top workmanship like Dion. Thank You
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
Great front line reception staff
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.
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 👌
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!
Had a urgent job to fit flashing light to a truck rung Voltaic and they were very accommodating and fitted me in the next morning
Anthony the auto electrician was a fantastic bloke and very accommodating to my needs nothing was a problem
Highly recommend this company and would definitely use them again
Thanks mate
Anthony great job 👍
Great experience with Voltaic all the way from start to finish. Jamie and Tara were very helpful with quotes, pricing and ordering. Anthony installed the light bar and UHF to my Hilux GR Sport with absolute technical precision and conducted himself like a true blue Aussie professional. Definitely be back for future works.
Awesome work Max had a new stereo system fitted very happy with it

Had a compressor fitted under the seat of my landcruiser great work thank you

Just had dual battery fitted to my 2023 Toyota V8 landcruiser thanks Max awesome job

The front bar lights and reverse lights are awesome as well thanks Voltaic great quality work I recommend Voltaic for all your car electrical needs cheers
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.
Recently had my ute fixed at voltaic James was fantastic to deal with as well as the girls on reception a very professional place I would not hesitate to recommend them
Booked and was in quickly.
Had a good consultation with the technician
Work was done quickly and efficiently
I was kept informed during the job by the tech about progress and any issues that may arise
