 Trustindex verifies that the original source of the review is Google. Got a 5kw solar and 8kwh battery system installed by Cahill and had a great experience from start to finish. Would 100% recommend them.  Customer service was top notch and the installation was quick and straightforward.  They made it easy and while it’s still early days, it’s good to see how much you’re generating and saving with the metrics in the app. 5 star!

 Trustindex verifies that the original source of the review is Google. Cahill Renewables installed my solar and battery solution November 2023. They have been incredibly professional and prompt at every stage from initial enquiry,  installation and after care service.  They were so efficient with the paperwork, which enabled me to be exporting back to the grid within 4 weeks.  I am really enjoying being a solar power user.

 Trustindex verifies that the original source of the review is Google. We chose Cahill Renewables to fit our Heat Exchanger as of all the people we talked to, they were by far the most professional in their attitude, explaining exactly what we would need. The team who came to fit it were there on time and got straight to work. They made a very neat job under quite difficult circumstances as we have a small bungalow with not much room to move  anything about. Apart from providing coffee and tea we didn’t have to lift a finger, for which, now getting on in years, we were very grateful.  They made an extremely neat job running the pipes under the house, so, no ugly fittings running along skirting boards, although of course this made the job harder for them it was their idea and we were extremely grateful. The whole service from beginning to end was extremely professional.  We wouldn’t hesitate to recommend Cahill Renewables in the future.

 Trustindex verifies that the original source of the review is Google. Having decided to have solar panels installed Cahill Renewables were one of five companies we approached for a quote. Right from the start we were impressed with their response, their efficiency and willingness to listen to what we wanted and to answer all the questions we had. The quote we received was competitive and having agreed a date and timescale for the work it all went ahead as planned. All of the guys who came on site were polite, considerate, careful and professional. They worked extremely well as a team to ensure the job was completed in a timely manner and kept the site clean and tidy. We enquired about having some additional electrical work done linked to the solar installation and this was scheduled to fit in with the existing work whilst they were on site. We have no hesitation in recommending Cahill Renewables to others. A great team in all respects.

 Trustindex verifies that the original source of the review is Google. Cahill Renewables have been absolutely great installing our home solar system.  They have been incredibly helpful from the initial quote, interpreting our needs to provide the final quote, installing all the panels and battery and then patiently explaining how the Tesla battery system works.  A very helpful and competent team which we throughly recommend.

 Trustindex verifies that the original source of the review is Google. Ended up not going ahead due to technicalities and planning permission requirements on my specific situation, but cahill renewables were the ones to go with if I did go ahead. Josh was polite and knowledgeable, got a very fair quote from them for a ASHP install and the quoting process was very pleasant and non pushy.
