Read moreMy first time using Flash Electrical & Data. I had a fantastic experience. James (owner) booked me in quickly and even brought the job forward when another appointment finished early. Matt & James (technicians) were very polite, friendly, and completed the PowerPoints & light switch updates efficiently. Pricing was very competative. Easy, professional, and reliable service - highly recommend.

4 Nov 2025Came through the door within 10 minutes after call. I discovered the issue ahead of time which made the repair works a lot quicker. Very professional and cleaned and removed all debris before leaving.

Read moreI was so impressed with these guys. Firstly their quote was 30% less than others for a residential electrical board upgrade, installation of fans and power points. When they arrived (three workers) they were friendly, polite, and personable; answering all of my questions. Then when they were finished they cleaned up all of the mess, leaving nothing for me to do! I would highly recommend Flash Electrical for all of your electrical needs!! Thanks guys for a pleasant experience 😁
