Our Testimonials
Hear what our customers have to say.
Great service. The team really know what they are doing I take a number of cars to them.
HM Auto Electrical have done almost all our auto electrical work from Utes to trucks. Michael’s work is second to none, expertly completed and never had failures to any installations or work undertaken. He is a perfectionist and thorough where reliability is always been a mark of his. From professional wiring to compliant and safe electrical work, I am always happy to bring something over when we need it.
I had a WOF done on a small trailer today. The staff member I dealt with could not have been more pleasant. The WOF was very reasonably priced as well. I will go back and have no hesitation recommending them.
