Comments; Always pretty nerve-wracking to have major works on your house, but Chelsfield is a real no-nonsense company, doing exactly what they said they'd do when they said they'd do it. I would recommend them highly as a very professional company and it is just such a shame that the government has cut the subsidy for so

Chelsfield Solar are a dream Electrical Service Provider, punctual, quality workmanship and delivered on what they promised. Like all good professional companies you have to book in advance, but the wait is well worth it. The team that attended were a mix of experience and apprentice which allowed the apprentice to obtain on the job training under the tutelage of a fully experienced coach and mentor. I would recommend to every single household in the UK, and am delighted that I now have electricity in my Man Cave - A job well done.

Chelsfield installed solar panels on my home roof. They were the most helpful and knowledgeable of all the contractors I spoke to, paid attention to my comments and made their own helpful suggestions. I spoke to several people in the organisation and found they were all knowledgeable and helpful. The installation process went without a hitch and I was very impressed at the installation team who did an excellent job, taking care to be as neat as possible with the fitting of wiring and wall boxes. The whole system was installed in one day. The panels have been working well since installation nearly 2 months ago. In all I am very pleased with my choice.

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.

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.

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.

I had a PV system fitted by Chelsfield in 2011, they did a really great job and the system ran flawlessly for years. I recommended them to friends and family. The inverter developed a fault after 14 years (typical life of this equipment). Chelsfield helped with advice on replacement options, pros/cons, clear breakdown of costs and pointed out specific details to help satisfy my existing FiT thresholds. Sourcing, booking and installation was all very fast, smooth and clearly communicated. The installation engineers arrived bang on time and were super-polite, tidy and took time to explain differences with new equipment, etc. I'd have no hesitation recommending Chelsfield, as a solid reliable PV installer. They are transparent and honest with the scope works and really look after their customers.

Thank you so much for taking the time to share such a thoughtful review. It means a great deal to us that your original system, installed back in 2011, performed flawlessly for so many years - and even more that you felt confident recommending us to friends and family. Long-term performance and trust are exactly what we aim to deliver. You’re absolutely right that inverters typically reach the end of their lifespan around this stage, so we’re really pleased we could help you navigate the replacement options clearly - especially ensuring everything aligned with your existing FiT requirements. Protecting those details is crucial, and we always want our customers to feel fully informed about the pros, cons and costs before making a decision. I’ll also pass your kind comments on to our installation team. Punctuality, clear communication, and leaving a site tidy are standards we take seriously, so it’s wonderful to hear that reflected in your experience. Thank you again for your continued trust in Chelsfield. We truly appreciate your support and recommendation.

We had Chelsfield install solar PV panels on our house in 2010. They have been so successful that we had the firm back in January 2015 to fit some more. The staff are professional, quick and friendly. If I had more money and more roof I'd have them again.

A very professional company which installed our solar PV panels expertly with a minimum of fuss and mess. They even revised their surveyor's plan on the day of installation to improve the look and positioning of the wiring and boxes. The PV panels have performed better than expected. Thoroughly recommended.

This company has just finished installing solar panels on part of the roof of my house and I have been delighted with them from the very first telephone call I made to enquire about the possibility of solar panels to the final installation. The first advantage is that Natalie who answers the 'phone knows all about solar panels and can give advice. I say this because of having to deal with receptionists at garages who know less than I do about cars but who block my speaking to someone who does. She advised me about which company to use to get an energy performance certificate which is needed to calculate the Feed In Tariff, gave me a detailed estimate, organised scaffolders and arranged installation the panels at a time to suit me. Incidently the scaffolders pointed out a missing piece of guttering even though I had had my roof checked a few months previously. I was therefore able to get this fixed while the scaffolding is in place. While it is true that the FIT has gone down so has the price of solar panel installation so in many cases it still makes financial as well as environmental sense. Now all I have to do is complete and send off the FIT forms: the most difficult part of the process!

Chelsfield Solar has supplied my 12 panel, 4kWp solar PV system. From enquiry through proposal, survey, quotation, installation and commissioning Chelsfield Solar provided a friendly and professional service and on site teams, who were quick and efficient, appear to me to have produced a high quality end product. I would happily recommend Chelsfield Solar to anyone contemplating installing solar PV.

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

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!)

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!

A very friendly team who not only did my photovoltaic panels but also lead me through the paperwork maze to get a grant to cover part of the installation cost. They put the panels up in March 2005 but came back recently to take the panels off temporarily while I had the roof repaired. They cover the south east of England (London, Kent, Surrey, Essex, Cambs, Hampshire, W&E Sussex, Beds, Bucks, Herts).

Really impressed with the service we've received from Chelsfield Solar. Their pre-sales advice was superb, unbiased and pressure free. Once I'd finally decided on which panels and inverter they were competitive on price. The installation of our solar pv system was completed on schedule and I'm confident it was done to a very high standard. They've been quick to respond to any queries I've had since. I would have no hesitation in recommending them to friends and family.

Everyone we dealt with at Chelsfield was professional, knowledgeable and took the time to explain and answer our questions. The whole service provided was excellent, from initial contact, through survey, to installation and follow-up. Communication by phone and email was fine and they kept us informed and replied quickly. The options for our installation were thoroughly discussed with us, and the products used were of highest quality, as was the workmanship. The price was competitive and good value for money. The time taken for the work was entirely reasonable, given that they were working outdoors on the roof in very wintry weather. We felt valued as customers and all the staff, both in the office and onsite were friendly and courteous. A pleasure to deal with this company and highly recommended.
