I’m very happy with the whole solar installation process. Everything went smoothly and quickly, and the team kept me updated at every stage. Whenever any issues came up, they handled them promptly and professionally. Great communication, excellent organisation, and overall a very positive experience — highly recommended!

I'd happily recommend ISolar. We had 16 solar panels fitted, plus inverter and battery. A prompt response to my initial query, providing the information that I needed without any pressure or 'hard sell'. A quick turnaround on the work done, with tidy results that I'm pleased with. Nice people to deal with.

Andy and Jez were very helpful and explained the system without any pressured selling tactics. The price was competitive compared to a few national installers. They helpfully arranged for the scaffolding to remain in place for a couple of weeks extra so I could do some work on the fascias, and they made the effort maximise the number of panels they installed, and took the time and effort to run the cabling internally and neatly. Great job guys!

I got in touch with several companies, iSolar were professional and prompt with responses. I feel I got a great price and a great service. The product I had stalled has already started to save us a lot of money and I would highly recommend to others.

We received 5 star service from start to finish with iSolar. They were thorough and adaptable to our requests. Whilst carrying out the work the team were lovely and easy to talk to. We’ve already recommended them to several friends and wouldn’t hesitate to recommend again!

Installed 4.4kwh of solar on our roof and 10kwh of battery storage almost bang on two years ago. System has performed flawlessly since installation and saved us a small fortune on our energy bills! Since our install my parents have also used iSolar and the In-laws get theirs installed in the next week or so!!! So far this year I've also made almost £140 exporting to the grid too!!!

Highly recommend this company! We had 13 panels and two batteries installed, the team worked efficiently and had everything complete in one day. We’re loving seeing the savings!

We had 8 in roof solar panels fitted on the front of our house following their recommendation on quotation, and 12 standard fit panels on the back of the house. Efficient, tidy, and extremely quick work, with a competitive price vs two separate quotes. Recommended to family that have also used your company. Great work.

Ben was fantastic from the moment I enquired about solar talking me through every step of the way ensuring I was getting the best service, price and equipment. His knowledge was second to none and would 100% recommend to anyone considering solar panels. iSolar were by far the best company.

I cannot recommend this Company enough. From start to finish iSolar personnel were very informative and answered all our queries. The Team that installed our solar panels were very efficient and kept us fully informed throughout the installation. We are extremely happy with the whole process and would highly recommend them.

If Carlsberg did solar, then they would choose iSolar as their installer. Top service from start to finish and beyond. No heavy sell, but attentive and listening sell, to what we wanted from the project and constructive and informative advice to get the best outcome. The installation team were of the highest order, their attention again to our requirements and their standard of work was outstanding, very polite and very knowledgeable and professional. Installing solar is a big life decision and to a certain extent it's a bit of a lottery, as there is a lot of companies out there wanting your business. We struck lucky with iSloar and feel very pleased with our decision to use them. I would therefore have no hesitation in highly recommending them.

The installation team was highly professional and efficient. They explained the process clearly, answered all our questions thoroughly, and left our property spotless after the installation. I appreciate the detailed explanation of how the system works. I already noticed a significant reduction in my energy bills and I am very happy with the overall experience

Great service from the whole Team. A few small dents in the wall of the stairs and landing, but the whole days installation went smoothly. Love the FoxCloud app - easy to see what's happening with my solar generation. I've now been able to choose a tariff with my utility supplier for nighttime low price battery top up, and on top of my FiT generation payout I'm getting an export meter fitted to get paid for any solar exported to the grid. Currently we're using 50p of lecky per day - most of that is standing charge. Having solar batteries has been the best decision we made.

Very responsive and professional service from the very first contact. There was no pressure from Jez during discussions, just good advice and we were given all the time we needed to make a decision. The quote was very competitive and for a higher specification than that from our energy supplier, a major UK company. Installation was at a time that suited us and the installation team were on time, very well organised and undertook the work very efficiently. The system has worked faultlessly from the outset and we're just waiting for the export to the grid agreement to start maximising the return for our investment. Can't recommend iSolar highly enough!

Fantastic Experience with ISolar - Highly Recommended! After extensive research and obtaining multiple quotes from various solar companies, I decided to go with ISolar, and I’m so glad I did! Here’s why: Unbeatable Pricing ISolar’s quote was almost half the price of a reputed company that claims to be the best in the UK. They offered nearly identical solar panels, the same battery, and the same inverter, making their value for money unparalleled. Straightforward and Professional Approach I had four other companies visit my home for estimates, and all of them used pushy sales tactics, spending over two hours trying to pressure me into making a decision on the spot. They gave false calculations and pushed monthly finance plans, leaving me frustrated. Andy from ISolar, on the other hand, stood out with his professionalism. He provided a competitive quote without any pressure and arranged for his colleague Jezz to visit my home. Both Andy and Jezz were honest, straightforward, and professional throughout the process, which made the decision to go with ISolar an easy one. Efficient Installation On the day of installation, the team arrived promptly at 7:30 am and finished everything by 2:30 pm, including the removal of scaffolding and cleaning up the site. My installation was particularly challenging due to the elevation at the front of my house, requiring scaffolding in different areas. The team handled it seamlessly and left no mess behind. Outstanding Aftercare Jezz provided me with all the relevant documentation, including warranties for the products, promptly after the installation. Their commitment to aftercare and ensuring everything was in order gave me great peace of mind. The installation team was punctual, polite, and incredibly friendly. Their professionalism and efficiency were second to none—an easy 10/10. If you’re considering solar installation, I highly recommend reaching out to ISolar for a quote before signing up with anyone else. I’ve already recommended them to several friends, and I wouldn’t hesitate to recommend them again. Thank you, Andy, Jezz, and the entire ISolar team, for an excellent experience! — Babin Joseph

After much searching and researching on the internet and getting in several quotes from different solar company’s we decided to go with ISolar. I’m so glad we did. As it turns out we had closed cell insulation sprayed directly onto the rosary tiles,so for a lot of the company’s I contacted they wouldn’t install with foam underneath. And other company’s came up with dubious methods of fixing thru tiles and leaving roof intact. When I contacted ISolar Andy and Jez couldn’t be more helpful. First off they sent a roofer to inspect roof,who said that foam was sprayed directly onto tiles and not as was thought onto felt. At this point I began to think I wouldn’t be able to have solar panels and battery installed after all, big disappointment. Andy and Jezz then came back and said they would get a quote to me for a reroof and solar installation all at same time. So I had a couple of quotes for a reroof from other roofers but ISolar turned out to be the most reasonable and inclusive quote. The team turned up on a Monday ( the scaffolding was erected on the previous Friday ) and the whole reroof ,solar panel and battery storage was installed by Friday at 5 pm the same week ……… very quick, very efficient and very clean install. The installation team were punctual, polite and a very friendly bunch 10/10 for sure . We wouldn’t hesitate to recommend ISolar. Mark and Mandy Fransham

I recently chose Isolar to supply and install solar panels for my home, and I couldn’t be happier with my decision. From the very first call to the final step of the process, the entire team was amazing. The office staff were fantastic throughout, providing clear and detailed quotes, and everything was arranged quickly and efficiently. They even coordinated with the scaffolding team, ensuring it was ready on the day of installation and promptly removed the following day after the work was completed. The installation team was equally impressive—meticulous in their work and very considerate of our property, making sure nothing was damaged. They truly went above and beyond. Even after the installation, they stayed in touch, offering invaluable advice on how to maximize energy savings. The whole experience was seamless and professional from start to finish. I’m extremely pleased with their service and will definitely recommend Isolar to all my friends and family. Well done to the entire team—thank you for a job well done!

A team of 4 arrived at 9 O’clock on the installation day, 2 went on the roof and fitted the 16 solar panels while the other 2 did all the electrics the whole job was completed by 2 O’clock they did a really good job and left no mess. I would definitely recommend this company to anyone wanting a solar installation. A++

I experienced a very fast turn around. From the brilliant quote on down through the order, deposit, scaffolding to the install was fast and easy. All done in just over a week. My power use from the grid is down by over 50%. Horrible weather is currently holding improved performance back but I know I only need a little sun and my panels (bigger than I was expecting) will charge my stackable battery with ease. The lads that did the work were great to be with and very friendly. A great experience all round…
