I chose Cahill after checking the "Which" reviews. From start to finish I have been completely satisfied with the communication, explanation and delivery of what was promised. The system was up and running in just over half a day, with no fuss and no mess. We have just had our first full day "off grid". The price was very good, especially in view of the overall quality. No hesitation in giving Cahill full marks.

Integrity, Quality and Attention to detail - Superb job!

We looked at several companies when considering our Solar installation. The key reason for us to select Cahill was the quality and manner of the interactions we had with Shane, the salesman who replied to our enquiry. At no stage were we put under any pressure, indeed He advised us when not to spend money as we wouldn't get the benefits from it. In terms of value, it was extremely competitive but extremely good quality, so the value was clear. Additionally, Cahill make a big thing about Ethical Sourcing and wanted to ensure that we had kit which was high quality and ethical. The quality of this interaction continued as we spoke to the directors and sub contractors who managed the install. They were very approachable and made good suggestions to improve the install. The sparkies were especially commendable and the quality of the install was superb. After sales service has also been superb and very responsive. We have already been delighted with the solar install and have saved significant amounts in just the first week. We would wholeheartedly recommend Cahill in every manner Great Integrity, attention to detail, quality, ethics, value and responsiveness Thank you!

Not necessarily the cheapest but but the whole process went without any hitches. Everything is working well. The electrician overcame problems routing the cabling to the inverter and battery so its all invisible.

My conservatory makes it difficult to erect scaffolding on to get access to my west facing roof. Numerous solar companies had told me it wasnt possible to put scaffolding up without putting legs into the neighbouring property which was not an option for me. Cahill Renewables took a look at the space they had to work in, consulted their scaffolder who said they could put up the scaffolding without needing the neighbours garden and got it done with no problems. The rest of the install went ahead with no problems. The staff are friendly and have provided brilliant customer service to me. I would recommend them to my friends.

Great work and great communications

I chose Cahill after reviewing many review sites and I can honestly say their customer service and their installation teams are excellent. From the initial phone call with Joe in the office discussing the technicalities of the solar panels, the inverter and the battery system they addressed all my technical questions expertly. There was no big sales push, once I received the quote, they let me decide in my own time and I had to approach them to place the order! Coordination and communication from George were excellent from when the scaffold would be erected to when the engineers and roofers would arrive. On-site discussions with their electrical install team (Ken) were clear and they understood my requirements with respect to cables being in trunking and the colour of the external conduit etc. Their installation is exceptional, and their communication exceeded my expectations, and I would highly recommend them to anyone looking to install solar on their property.

We wanted a solar system and, after many false starts, were lucky enough to find Cahill Renewables. From the start they did everything they could to build us a system that matched our needs. They gave us an installation date but put the panels on the roof 2 weeks early. They then tried to fit the remainder of the system a week early. This did not happen, unfortunately, due to the electrician having an accident. They did come to us on the due date and installed, over two days, a brilliant state of the arc system. It works better than we could have wished for. All the people we have dealt with at the company have treated us with care and consideration. These people really do care about their customers. We would not hesitate to use them again.

We would be very happy to recommend Cahill Renewables. They were extremely helpful in talking us through the options when we first enquired. Their communications were excellent throughout, and they did exactly what they said they would do when they said they would do it. All of our dealings with Cahill were good but Joe, the Office Manager, handled our questions with professionalism, patience and good humour.

I contacted Cahill Renewables, after reading some of the reviews about the company. After speaking to George the contracts manager about the fitting of Solar Panels, I found him to be extreamly helpful, and was not at all pushing to get a sale. He very worked out a price for the system that would suit my requirements, and an aggrement reached. The fitting team arrived on time, and the three team memnbers were all very polite, and helpful with advice when needed. Their work was neat, and tidy, and they really worked hard installing the equipment. I would certainly recommend Cahill Renewablesto others thinking of having Solar Panels fitted.

Cahill Renewables have been excellent at every step of this process. Their quote was competitive and transparent. They have ensured that each step has been communicated well; excellent customer service is clearly important to them. The installation has come in three steps: scaffolding first, then 2 days later the panels installed with the next day down to the electrician and connection. All these steps have been undertaken by prompt, efficient and friendly people. I would not hesitate to recommend Cahill Renewables
