Since buying a newly built house in Hervey Bay we have used grc to install our solar panels, air conditioners, to increase the number of TV connections and many more power points. We have found that not only was their service top shelf but the guys who did the work were exceptionally helpful and very polite. In summing up it is easy to see why this company is so successful when you look at the people you deal with from Gary and Christabelle down to the young fella who takes his boots off before walking in the door. I would highly recommend this company.

GCR Electric did a fantastic job replacing our solar panels. The job was extremely difficult due to high slippery roof. I would recommend GCR for any electrical job. Guys were friendly and professional.

We have just had a Solar System installed by GCR Electrical Systems. From the first time we met Gary he was very professional and explained all of our options to us so we could decide which System was suitable for us. The installation was very prompt and professionally done. I would recommend Gary and Christabelle to anyone who needs any electrical work done.

Gary and his team came highly recommend to us when we moved to Hervey Bay a couple of years ago, we had quite a lot of electrical jobs to be done in home and around the property, from running power to my shed which was about 30 metres from the house connect the power up to the new pool pump and water feature, installation of three split air conditioning systems and multiple Big Screen TVs around the house which they happily mounted to the walls, added extra power points where they were needed, and the big ticketed item of 36 micro inverted solar panels, we were more than impressed with Gary and his team of tradesmen, I have had to call Gary a couple of time just for advice and nothing is ever a problem for him he always responds promptly and his happy disposition makes him so very easy to deal with. Absolutely no hesitation in recommending Gary and GCR ELECTRICAL for all you electrical and solar needs.

We have had a 6.6 kw system with a Fronius inverter and Winaiko panels installed in Feb 2020. After tackling the minefield of solar retailers, thankfully we were recommended to talk to Gary and Christabelle. The entire process was handled professionally from the initial contact when we lived interstate through to the very tidy install and after sales service. Gary’s advice on what we needed was superb, I had so many questions! We had no idea of our power use as the house had been a rental, but early numbers show we should have reduced our bills to approx $0 a year so the system will have paid for itself in around 4 years. Could not recommend GCR enough. Thanks Guys, A and H 😁

Very happy with our experience with GCR Electrical Systems! We have had them out for a number of jobs over the last few years from updating smoke alarms, installation of fans, down lights and adding a solar system to our home. Gary is great at letting you know what would work best for your home. We also love knowing we are supporting a local family business. Highly recommend

GCR were recommended to us by a friend after we had received 2 other quotes. Gary visited our premises advised on what was required gave us a price which was competitive from there we never hesitated.From Gary to Christabelle to the guys on site everything went smoothly and professionally from start to finish .We definitely will be referring them to family and friends.It is very pleasing to be able to refer a local company so highly.Bob and Sandra (Urangan )

Gary, Christabelle and the rest of the GCR team were awesome. They were great communicators, very easy to deal with and honest about the best options for my place. Unfortunately, due to my local transformer (Kawungan) being 130% over capacity Ergon won’t pay me a feed in tariff due to their poor infrastructure and lack of planning for a decentralised energy system. This wasn’t GCR’s fault but disappointing for the community given my neighbours will also be in the same position when they go to install solar unless Ergon upgrades their infrastructure. GCR 5/5. Ergon 1/5.

From the moment I phoned GCR electrical I knew I made the right choice from the quote to the end of the job was a very pleasant experience. They dismantled my old system put a new 6.6 system on my house and the team that done the work wow what a great team. I highly recommend GCR electrical. Gordon Merchant

Gary and his team were extremely professional and helpful. Price was on par with other major retailers, and the gear is the same / comparative too. I got quotes from 3 retailers, and for the gear we got GCR was the best in price.Installation - the team was on time, efficient, and thoughtful. To spend the hottest part of the day on and in the roof and then take time to explain it all afterwards was great.Highly recommend, I am normally skeptical of small businesses with low reviews, but GCR’s has definitely earned the 5 star rating on here.

Their team of upstanding professionals carried out our recent solar install efficiently and to the highest standard. I look forward to having GCR carry out any of my electrical work in the future and I absolutely wouldn’t hesitate in recommending them to anyone looking for the best electricians on the Fraser coast. I’m an extremely happy customer.

Recently had GCR Electrical Systems install a 6.6kw system on my property in Urraween. From quoting, booking in of the job, installation and quality of works the service was exceptional and beyond expectations.The whole operation from start to finish was professional, all of the men who installed the system were careful with my home and also took care to clean up completely after the job. Gary's advice regarding the solar was second to none and he was able to answer all of my questions. It's been a great experience knowing how everything works and functions in regard to the system installed!I wouldn't hesitate to use GSR again when needed! These guys are pros!

Gary and his team have just completed fitting a new 6KW SOLAR system and a 6.5KW MHI A/C unit to to my rental properties in Urangan. He provided very competitive pricing. Gary understands the latest electrical regulations and compliance. His workmanship is neat and top quality which is important when installing roof mounted SOLAR panels. All work was carried out in a polite professional manner, an excellent quality job without fault.

Rowan, Your team are both very efficient and courteous, upon arriving they have measured and checked the shadowing effect of the neighbouring trees and have discussed; strings for the inverter, positioning of the banks of panels, shadowing of the panels and the effect for summer and winter. Thank you and the boys for the installation, we are very happy with you and your team for a professional attitude to having the Solar Energy System installed
