Cahill Corporation Ltd t/a as Cahill Electrical and Cahill Renewables

It’s been five months since my solar and battery installation, and everything has been working exactly as expected. From the initial call with Josh to the office team, the surveyor, the scaffolders, roofers and electricians, every single person I dealt with was professional and accommodating. Minor hiccups were addressed effectively. The quote was well presented and looked professional. Cahill offered me the best hardware for my needs (high-efficiency AIKO panels and a Tesla Powerwall 3) at a reasonable price. The sales team were responsive throughout the process, answering my technical questions promptly. Antony, the surveyor, took the time to understand my requirements and reassured me about the installation, confirming the optimal number of solar panels to maximise my roof space. At that point, I knew I could trust Cahill to deliver, and I was happy to proceed. Scaffolding was up within two hours and held firm during several days of strong winds. On installation day, the team arrived on time, which was excellent. The lead electrician deserves special thanks for coordinating the team and completing the underground ducting neatly despite the challenges. The roofers installed the solar panels efficiently and were happy to answer my questions. Before leaving, the team walked me through the Tesla app, and the system was fully operational. I was able to start saving immediately by reducing my reliance on the grid. Exporting excess solar and battery energy required permission from the DNO and my energy supplier, along with some help from Tesla support, and Cahill assisted with all of this post‑installation. What set Cahill apart was their willingness to go the extra mile — nothing was too much trouble. Choosing a reputable installer isn’t easy, but Cahill delivered a compliant, high‑quality installation without cutting corners. I’m very happy with the system and would confidently recommend Cahill Renewables to friends and family.

Have been extremely pleased with the service provided by Cahill Renewables from start to finish. Pre-Sales advice and response times were fantastic, I had lots of questions and looked at many different variations of system and their team was able to support me in making the final decision. The installation itself was extremely smooth, I honestly couldn't quite believe it could be achieved within a day but the team got everything done with minimal disruption, power off for no more than 5 minutes and I'm extremely happy with the quality of workmanship. I wouldn't hesitate to recommend Cahill Renewables to others.

From first contact to completion of install Cahill have been a pleasure to work with. I'm happy to support a local business that provides quality workmanship and at a competitive price. Thorough explanations were provided at quoting and after installation. Highly recommend this team if you're looking for anything electrical or sustainable energy related

I must say what a pleasure it has been to do business with such a friendly and helpful company. Josh, you have been brilliant and very helpful explaining the ins and outs of how the system works and making sure that we have the best system that meets our needs. Ross our surveyor was also helpful, friendly and very knowledgeable. The ladies in the office were friendly and extremely efficient. Even James your delivery guy was friendly. And finally Jim our engineer. What an: Amazing, conscientious, happy, helpful and knowledgeable young man he is. Nothing was too much trouble and his work was exemplary. So neat and tidy and not a scrap of mess left behind. He explained everything to my husband Brian and I, went through the app with us and went well beyond what we would expect from him. So thank you all for making this a pleasurable and exciting experience. We will have no hesitation in recommending Cahill Renewables.

Thanks Cahill Renewables for your honest advice. I randomly called Cahil Renewables after my mum was quoted a large cost by another company for some new solar equipment. As a family we wanted to check if the equipment was needed and the costs quoted. Cahill Renewables was really helpful and supportive in answering our questions and assuring us that the other company was potentially scamming my mum. Josh and his colleagues were very open and honest in their opinions, we are very grateful. We will certainly go back to Cahil Renewables in the future.
