Third installation by this firm and would not use anyone else

Our first installation in 2010 was for solar panels and along with the vast majority of your customers we received great advice, fault free installation, and clean and tidy working. The inverter failed some years later and was replaced with equally good work. Our second installation 2 years later was for further panels in advance of the FiT rates dropping and was equally efficient. Inverter failed some years later and was replaced at minimal cost to us, by Mike We have just had three further panels on a different facing roof and a battery installed this week which is neat and tidy, they were in and out in the day They always turn up when they say, they arrange everything and appear to charge fairly. Unlike some Solar firms they are still around many years after first installation and appear to be set to stay in business for a long while to come - rightly so.

We are very grateful to the whole team at Chelsfield Solar for installing our solar panels. The company was recommended by a neighbour and we did not regret. The engineers completed their job outstandingly professional. The office ladies, Lorna and Clare were very helpful, responding to our queries promptly and supporting us through the whole procedure. A massive thank you!

Contacted Chelsfield Solar to increase the battery capacity of my existing Givenery battery system. They had fitted the existing system some 2 years ago. Sent them some photos of the system and from that they were able to provide a quote which was acceptable. The upgrade was fitted a couple of weeks later with no issues. They were professional, competent, friendly, and a pleasure to deal with and I would certainly recommend them.

Needed new Inverter
My inverter for the Solar had stopped functioning. So It didn’t matter how much sun we were having my system was not working. I called on the Monday and explained my problem, this company had installed the system some 10 years earlier, they held all my details and were able to order the inverter immediately. Two days later, a team arrived and installed the inverter, which took them 30 minutes. I was extremely pleased with their performance and the speed at which this all took place. Fortunately, they had the inverter in their stock, which was an added bonus. This was only the second time I’ve had trouble with the Solar, and on each occasion, they have dealt with me in a personal and efficient way. Many thanks to a well run crew.

We shoppe around for PV installers, got a referral from a friend and got Chelsfield round for a quote. They were by far the most knowledgable and clear on what options we had. They did some extra cabling work for us to make our set up easier. Installation was done on a rotten weather day but they didn’t flinch, did the work, and left no mess. It all works great and they talked me through the management & monitoring of the system.

Thank you so much for taking the time to leave such a thoughtful review. We’re really pleased to hear that the referral led you to us and that our team was able to clearly explain your options and design a setup that works well for you. Even in less-than-ideal weather, it’s great to know the installation went smoothly and that the extra cabling work made things easier for you in the long run. We’re especially glad everything is performing well and that you felt confident managing and monitoring the system afterwards. Thanks again for choosing Chelsfield, it was a pleasure working with you.

Chelsfield Solar were very efficient. The scaffolders came when they said they would. The fitters came promptly and were very good. We were very impressed with the company and would highly recommend.

We had solar panels installed whilst converting our loft and replacing the roof taking advantage of the scaffolding already there. Natalie provided clear and helpful advice on the phone for which type of system would work best with the design of the roof (completely different and more efficient than my thoughts). The company has been easy to deal with, efficient and professional. Chelsfield liaised directly with the loft company. The struts for the panels incurred an additional expense as did the detailed plans hence extending the time to recoup costs but this was not the primary aim. I would definitely recommend this company.

We contacted Chelsfield Solar about a problem with pigeons underneath our solar panels and the resulting earthing faults. From the first phone call they had a good understanding of the situation. They were prompt in responding and efficient in the work they had to do. At all stages they were courteous and helpful, explaining what they had to do. We felt confident in what they were doing. Chelsfield Solar will be our first choice for help if there are any further problems with our system. We strongly recommend them.

When we started considering solar panels Chelsfield were recommended to us. They gave excellent advice - they really know what they are talking about - with absolutely no pressure. The date of the installation was agreed, and it was started and completed on that day. All the work was finished very tidily. There was information and advice given by the electrician on the day, and a pack followed very shortly afterwards. Nothing is too much trouble.

Solar and batteries fitted, after sales good to start then trailed off. Owner came to try to sort problems but advised got him beat and he would look into it possibly three to four months ago no contact since, even though I have sent Mike photo's, I then texted Natalie on 24th June 2022 who advised she would get back to me still no contact. My Energi has been excellent we were sold their App with the solar we have had two new hubs trying to solve the problem and they then advised me (talked me through it) to switch the wires on one hub, It now works perfectly (fingers crossed) So the installation was incorrect for the last eighteen months. Would not recommend.

Thank you for your feedback which we take seriously. We are currently inundated with work and unfortunately this has not allowed the time to respond to all customers in a timely fashion, for which we apologise. As your solar PV, battery and EV system were all working, your query with regard to an app unfortunately took longer to respond to than we would like. We are very glad MyEnergi were able to help.

For what we paid for an inspection of our solar installation - £192 - I now realise (after having had a proper inspection by a very good firm) that Chelsfield were useless. They stayed about 30 minutes, picked up one obvious fault and left. Days later we had to prompt them for the written report, which they had forgotten about. Claimed they could not inspect everything due to 'lack of light'. Fact check - there is lighting in the loft; and torches can be bought cheaply! They missed all the critical faults picked up by another company. Should have given us our money back. Such a poor and unfriendly service.

Dear Customer - Further to your review we are most saddened and surprised to hear of your dissastifaction. We performed a system check for you as you felt the installers of your system had let you down. We received an email from you on the 17th November thanking us for the report which you said was set out clearly and useful. On our report we mentioned that you should monitor the system for the next 2 weeks to check that the remedy was stable - we have not heard anything at all from you since this email. The lack of light you mention was not in the loft, it referred to the fact it was a dark/cloudy day therefore the Solar PV would not be generating. It is most upsetting to find this review when you have not contacted us directly to discuss. If you felt we had not completed our job properly we would have of course rectified this.
