Solar install

I had a large solar and battery install for my property. I had quotes from lots of companies and decided to go with K Cahill due to the fact there was no hard sale talk, they worked with me until the install day and even had extra's added to the install at short notice and that was no problem to them. The work force that came to my property was a great bunch of lads, anything I asked for was no problem. Over all extremely happy. Thank you to every one at K Cahill Renewable. Top Job.

I've recently had solar panels, together with batteries and Solar I Boost+ installed by this Company and can HIGHLY recommend them in all aspects. I had looked at many reviews before requesting a quote for the work to be undertaken, and all my expectations were exceeded! Following my initial telephone enquiry to the office, Joe and George were extremely helpful and knowledgeable. Once my objectives and circumstances were discussed, Joe provided a prompt detailed quote which was modified, after discussions, several times over the next few days. The professionalism was exemplary without any "pushy" sales techniques. At this time, I had been exploring the possibility of participating in the Essex County Council Solar Together scheme and had submitted my details. I was so impressed with K.Cahill that I decided to use them prior to receiving the quote from Solar Together. In the event, K.Cahill were 10% cheaper for a much better service! Installation was undertaken only 3-4 weeks after contracts were signed and, on the day itself, everything went very smoothly with minimal disruption. Keiran, the electrician and Steve & Lewis the roofing panel installers were, again, extremely professional, knowledgeable, friendly as well as being very tidy. Everything was completed on the day, and we were generating our own electricity by 2 pm!

If you are thinking of having solar panels installed - this company is epic. Pre-sale: I spent considerable time researching different companies and it was a minefield. Eventually, what persuaded me to go with K Cahill was my communication with Joe in the sales office. He was incredibly knowledgeable and helpful - without being pushy. The system options were explained fully and all my questions answered. There was never a point where I felt pressured into anything. Pre-installation: Once I decided to go ahead with the installation, my perception of the company only improved. On two occasions I was given automatic upgrades of equipment (first more efficient, higher capacity panels, and then an upgraded battery) for no other reason than new, improved equipment was now available. Installation: The scaffolding team (I believe sub-contracted) arrived on time, were efficient, polite and had the scaffolding erected within 2 hours. The installers (lead by Kem) were amazing. Again, they arrived perfectly on time. Very tidy, (shoes removed when entering the house, without being asked), incredibly polite and had the installation completed and up and running within 4 hours. Amazing. After sale: The after-sales contact has been brilliant, with a thorough run-through of the monitoring system. Our panels are functioning amazingly well and our electricity usage from the grid has plummeted. Happy days. So completely happy with this installation and cannot recommend K Cahill highly enough. A*

First Class Battery Storage Installation

Very impressed with K Cahill. They answered what must have seemed like a never-ending list of questions about battery storage before we ordered. Email communication and replying to calls was always prompt. We had a very professional installation followed by a long one-on-one call to explain how the monitoring system worked online and to answer any questions. It was a first-class service from start to finish! We have no hesitation recommending K Cahill and will certainly use them again when needed.

K Cahill was very quick to respond to our initial and every consecutive enquiry which means a lot. We already have the panels on the roof whilst we’re still waiting for an alternative company to contact us regarding our request for a quotation. K Cahill has been very professional in how they handled our enquiry from beginning to the end, they’ve shown flexibility in accommodating our requests. They were really friendly and patient with all the questions we kept throwing at them. As a company they are very experienced and knowledgeable. Very good customer service. I can definitely recommend to others.

Fantastic service and system

I approached K Cahill after I had been badly let down by another PV system provider. I was given good advice, no pressure and an extremely quick installation date. The team of two arrived when expected and tolerated my poor jokes about getting a move on because the sunlight was being wasted! Two days later and the battery is fully charged and the system is exporting electricity. The only glitch has been that the export meter is faulty - there is no way they could have known that, and a replacement is coming. George has been extremely friendly and helpful both with the planning, communicating regarding the installation and now solving the problem. Nobody could ask for more. I have ended up with a better system than I originally intended, better value and much quicker than expected!

I would just like to thank George for his advice and planning for the solar and storage. Nothing was to much trouble and he was always at the end of the phone. From initial enquiry to installation in around two weeks. The team arrived as planned to fit the system and nothing was to much trouble for them. Very polite and professional at all times. The work was carried out superbly with no disruption or inconvenience to us. All works was done very tidely with no mess at all. I can highly recommend K Cahill renewables to anyone looking to fit a solar system. All done to an agreed schedule at the cost agreed.

A great service from start to finish. George in sales was helpful with reviewing options and we agreed the final proposal and price easily. The workmanship was great and the guys that came to the house were friendly and got on with things very quickly. They also left everything tidy as well which can be an unusual experience with trades!

Excellent work
The job: Solar panels with batteries in the attic and a heat pump with new radiators and water tank. A price was agreed at the start and never changed. The job was started on the day that was originally agreed and finished on time. From my first contact with K Cahill Renewables I was impressed. George kept me informed from start to finish. Any questions I had were answered promptly. He went through everything thoroughly, explaining what was going to be done and in what order it would be done. The contract was also explained in great detail. Whilst the work was being done he kept in contact to make sure I was happy with the progress being made. Darren the plumber was polite, friendly and always happy to talk about what he was doing. Kieran put the panels on the roof and was also polite, friendly and happy to explain what he was doing. The whole process was well planned and executed. I would be happy to use this company in the future and recommend them highly. They are all very pleasant, happy, polite and trustworthy.

I can thoroughly recommend K.Cahill who installed our 6.8kw solar system with 6.5kwh battery. We moved into our new house a few months ago and got 4 quotes from a couple of local suppliers and a couple of national providers. K.Cahill were not the cheapest but suggested a good system, have a strong background as electricians and George in the office was able to answer all of my many queries. Initially we agreed on 14 panels being installed on the SSE and WSW facing roofs, with additional panels being added at an agreed rate each should more fit. On the first install day Keiren, Kem and Jermaine attended to do the install. They were able to fit 14 panels and install the battery and inverter over the course of the long day. They were able to position them better than I had expected with micro inverters on all of the panels which might be shaded over the course of the average day. Kem followed up for a second visit to fit 5 additional panels in positions agreed on the first install date. Keiren got the system connected to the internet and set up the mobile app for me so that I can see how the panels are performing and showed me how to best control the system with advice on maximum effectiveness. All ran very smoothly and I'm delighted with the performance of the system as well as the placement and look of the panels. From their and my own research, as well as the rapidly increasing energy prices, it should pay for itself within 10 years, after which time it's all profit. I can and will thoroughly recommend K.Cahill and his team for anyone interested in a solar system.
