"I just had solar panels fitted by Cahill Renewables. I could write a long review here, but I will keep it simple, from first contact (with George) through to scaffolding and fitting of panels, the whole experience has been EXCEPTIONAL. I work in Customer Services for a living and these guys have exceeded my expectations at every point in the process. I highly recommend using Cahill Renewables if you are having Solar (or anything else for that matter) as the knowledge, care and professionalism are simply excellent from every team you work with."

Cahill did an excellent job, both on the 6th-7th when the work was done and before and since. Everyone is polite and helpful and the installation workers were clean and efficient.

After contacting this company for a solar panel installation quote, they called me to discuss it and asked me to email over some photos, to George the sales director, of my roof to see what could be done. I didn't get a response, so a week later I sent a follow up email and still no response. I then waited about a week before using the contact me form on their website, still nothing! I put a negative review and then they claimed they didn't know me, I proved to checkatrade I had had contact and then they came up with lies stating they called me, to cover themselves. Unprofessional behaviour!

Anyone who is considering having solar panels installed, look no further. K Cahill Electrical and Renewables are the company you need. There is no hard sell, just clear information and advise, fast and efficient fitting all staff are polite and helpful. George was very patient and understanding with my never ending questions and queries. Many thanks to the whole team, we are loving our Solar energy, 1st Class company.

I had a large solar and battery install for my property. I had quotes from lots of company's and decided to go with K Cahill due to the fact no hard sale talk, 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 :)

VERY HIGHLY recommended. Joe and George , in the office, were extremely helpful and knowledgeable without being pushy and quickly proposed a system which met all my needs. Installation took place within 3-4 weeks and everything went very smoothly with minimal disruption. Keiran,the electrician, and Steve and Lewis, the roofing panel installers were also extremely extremely professional and knowledgeable. A couple of days later,with data to work with, George telephoned to take me through the details of the monitoring system. Very rarely have I received such excellent service from a company !

Joe in the sales office was incredibly knowledgeable and helpful. All options were explained fully and all my questions answered. There was never a point where I felt pressured into anything. I was given automatic upgrades of equipment simply because new, improved equipment was now available. The scaffolding team 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, were tidy, polite and had the installation completed in under 4 hours. After sales brilliant. A* service throughout

After looking around for a while for the ideal configuration I researched K Cahill and saw the reviews. Although they were based over 50 miles away I thought I'd give it a try. From the first call with Joe the process has been really upbeat and honest. We arranged a date, the contracting process was really organised and dealt with remotely. Joe also called a couple of times to confirm arrangements and configurations. On the day of the Job the team turned up on time, were really courteous and cracked on. Nice tidy job and worked well as a roofing team (outside) and electrical team (inside).

Received a quotation without delay, installation done a week earlier than expected. On the day the team arrived early , completed the work to a high standard and to our satisfaction. Recommended.

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.

This company was great throughout the whole process from first enquiry to final installation and a warm house and lots of hot water. No heavy sales pitch...lots of explanations for me, checks and balances in place so I didn't make hasty decisions. My career had me involved in jodpital refurbishments which I didn't say to George at KK Renewables....I Can't recommend KK Renewables highly enough. Contractors second to none. Excellent work throughout.

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. All employees were polite and friendly. The whole process was well planned and executed. I highly recommend this company

I can thoroughly recommend K.Cahill who have just installed our 6.8kw solar system with 6.5kwh battery. We 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 and George in the office was excellent and I felt I could trust them the most. 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. In the end we managed to get 19 panels installed in two days and it has been excellent thus far with no issues.

K Cahill did not do any work for me, but what they did is outstanding. Just moved into a place that had solar panels but were not working. Speaking over the phone and email they got me 'on-line'. Big thank you to George who explained everything and more. Any problems, give them a call, outstanding service.

Excellent job from initial contact to completion. I was kept informed of progress, given start date, how long job would take. Very neat and tidy job.

Before you hire an electrician

In England and Wales, notifiable electrical work (new circuits, a consumer unit, anything in a bathroom or kitchen) must by law be signed off under Part P of the Building Regulations — confirm they will handle that.
Prefer an electrician registered with a government-approved competent-person scheme (NICEIC, NAPIT or ELECSA) so they can self-certify the work meets the wiring regulations.
Insist on the Electrical Installation Certificate (or Minor Works Certificate) when the job is done — it is your proof the work is safe and compliant, and you will need it if you ever sell.
Look for consistent reviews across several named sources, not one polished profile.
Check any verified credentials, and that the business details independently check out.
