After being taken for a ride by many other companies. It was amazing to find a professional company that saw my problem as a problem and not a way to get loads of money! Ben Jonathan and Lorna all went out their way to advise me on the best way to deal with a leak that had developed. They were patient and professional. I would recommend them to everyone and anyone!

Battery Installation

Chelsfield Solar have previously installed our solar panels and EV charger both of which we were very pleased with. I had several other quotes for the battery installation but Chelsfield were the cheapest; one company's quote was nearly double! The whole process of sizing, quoting, surveying (siting the battery and choosing a cable route) and installation went very smoothly and to schedule. Vivek (the technical guy back in the office) was very helpful before and after the installation; in particular in tweaking the settings in the app to get the most out of the battery. So our third project with Chelsfield definitely lived up to our expections.

Chelsfield were recommend by a friend. Their quote was not the cheapest ( mid range) but they were the only company to visit to check on viability of installation. They speedily responded to my requests for different options to consider and my requests for specific cable routing and the siting of the inverter in my garage. I always worry about deposits and completion but didn't need to be. The installation was very efficiently carried out by the family+ team. They were clearly experienced and more than able to deal with the electrical work involved. All very pleasant to host for the day. A minor glitch with the inverter was resolved quickly with a return to my property the next day. My only (minor) suggestion for improvement would be a clearer indication of the steps along the way; what will happen when. I have no reservations in recommending Chelsfield.

Incredible company
We recently contacted Chesterfield Solar to quote for solar panels supply and fit on an airspace development we carried out. We had not worked with them before, but had been recommended to get in touch and could not be happier that we did. Their quote was turned around with incredible speed. Their initial price came in on point (slightly lower than who we usually use) and communication regarding on site preparation was was detailed, and swift. All answers were given with utmost understanding of site specific requirements. Installation was a breeze, done and dusted within a day, even accomodating last minute layout changes, and we could not be happier with the end product. We are really happy we now have a trusted provider for solar panels, there for us, whenever we need, for whatever we need. They uphold the statement of " no job too large and no job too small". Whoever said you cant have quality, price and speed, just hasn't met Chesterfield Solar.

Absolutely brilliant team. Unlike other suppliers I have spoken to, they don't provide a cookie-cutter system; they really do know their stuff. From the sales people (Edward was amazing) and the full install team. Clean, tidy. Wouldn't hesitate at all to give Chelsfield a solar project if you are thinking of it.

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.

Use Chelsfield Solar for your UV panels and you won't be disappointed. I would just like to say that the service that Chelsfield Solar provide is second to none. The failure of our solar panel was dealt with real professionalism. The Staff in the office and engineers go above and beyond what is expected. I would have no hesitation in recommending Chelsfield Solar to anyone who will listen. Chelsfield Solar have also just fitted my EV charger. It was a no brainer to go back to these guys for another professional installation.

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.

We recently purchased an empty property and as the previous owner had passed away we had no reference to the Solar PV kit that we had taken on. We were recommended to Chelsfield and from the first time we met they were outstanding in every way. They were especially helpful in assisting with getting the FIT ID transferred to our name which was challenging at times as we have not had Solar PV in the past and our knowledge was zero! All costs for the proposed work were provided in an estimate in a clear and timely manner. The initial survey which outlined some issues we had was comprehensive and easy to understand and the follow up service from the technical guys was thorough and completed to a high standard. Chelsfield were very professional, honest, knowledgeable, friendly and most importantly patient to us newbies - a superb company to work with.

I would definitely recommend Chelsfield Solar as I have found the whole company to be completely professional and supportive in all ways. From the prompt communication about the installation (6 solar panels on the front of the propery), patience and support for any issues I had to the actual installation itself, I cannot fault them in any way. They go the extra mile for you, explain everything you need to know and are very fair in their pricing. You will not get a better team!

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.

I wholeheartedly recommend Chelsfield Solar to anyone considering having solar panels installed on their home. Their exceptional customer service, meticulous attention to detail, and commitment to excellence have made them a true partner in our journey towards sustainable energy use. Our home presented a unique challenge due to the presence of two meters/MPANs and an annex. The team at Chelsfield Solar rose to the occasion, meticulously assessing our property and thoroughly explaining our options for optimal panel placement and power system configuration. Prior to panel installation, roof work was required. Chelsfield Solar seamlessly coordinated with local tradesmen, ensuring our project progressed smoothly within the established timelines. A large team arrived on-site, exceeding our expectations in terms of both work quality and consideration for our family and neighbors. Even after installation, Chelsfield Solar's support has been unwavering. Twice I visited their store with questions about system maintenance, and each time, the team was friendly, patient, and dedicated to helping us maximize our energy provider benefits. Choosing Chelsfield Solar for our solar panel installation has been an absolute pleasure. Their expertise, professionalism, and commitment to customer satisfaction are unmatched. I wholeheartedly endorse them without reservation. (Yes, this is a genuine review!)

The team at Chelsfield (particularly Natalie) have always been helpful and responsive with every query, from my initial solar installation, over 12 years ago, to my battery instalation, a year ago, and more recently to help me with schematic's and switching FIT from on provider to another. Great team and company I cannot recommend them strongly enough.

Chelsfield Have been totally professional from the very start of the process. From the initial enquiry to the completion of the installation. The initial enquiry was dealt with promptly. They arrived on the Date specified to carry out the survey for the quote. The quote arrived when they said it would and they promptly answered any questions I had. The installation date was booked and carried out on the date specified. On the installation day 6 fitters arrived and the installation was carried out efficiently and completed on the same day. The installation is extremely neat and all mess removed from the house. All 6 fitters were polite helpful and a pleasure to have around doing the install. Would Highly recommend Chelsfield for a solar installation

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.

I had a Solar PV and Battery system installed by Chelsfield Solar. I felt Chelsfield presented me with the best options really taking into account the location, surroundings and my electricity demands. They knew the area and were even aware that I would have to navigate getting extra approvals as it was a conservation area, not wanting me to proceed until I had all appropriate permissions in place. I was informed of supply issues around the battery in advance, they highlighted and discussed price changes (which in the current climate were not a surprise) and they provided options to me if I had wanted to look at cheaper alternates. They kept me informed throughout the process. Everything was done to schedule from site survey, scaffolding to installation. They genuinely seem to care about the environment and ensuring you have a system that will operate well for you. I found them knowledgeable, professional and helpful. I would highly recommend.

Although we did experience a few supply chain related issues (over which Chelsfield Solar had no control), we are very happy with service and installation we have received. Pre-sales was great, with all the options well explained and regular updates regarding delays to the panels and battery. Sites site visits were punctual and informative, and the scaffolding was put up and dismantled on the days agreed without any fuss. Finally the installation team did a great job even when presented with a few left-field challenges in the form of a brand new version of the inverter! Investing in solar is a complex process, but I am confident that thanks to Chelsfield Solar we have the right system for our needs and any issues will be dealt with effectively in the future. Highly recommended.

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.

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.

Chelsfield were on my short list of potential installers. By chance they were carrying out an installation nearby so I was able to carry out due diligence on both the scaffolders and the installation team. All very positive so I asked for the survey which was also excellent with practical sound advice on the positioning of the panels. As anticipated everything proceeded smoothly and efficiently with great level of communication with everyone in the team So highly recommended.
