Carbon Saving Group Limited customers often praise Callum Kerr for clear explanations, thorough surveys and helpful after-sales support, with several reviewers saying he made the process easy to understand. Reviewers also report clean, tidy and professional installation work, including solar panels and batteries fitted in a day or two, and some mention Kathryn Smith, Neil, Tom and Mike positively. One reviewer was pleased with a gas boiler installation and another with underfloor insulation. One reviewer criticised missed and rescheduled inspection appointments, no phone support at weekends, late confirmation of payment and delayed paperwork, and said scaffolding contractors were rude and damaged fence panels and a garden light. Another reviewer said their app stopped working after installation and that repeated requests for help went unanswered, while two earlier reviewers reported difficulty getting calls back.
I chose Carbon Saving Group to install solar panels, battery and heat pump as, although they were not the cheapest (or the most expensive) quote that I received (and I had a few), they stood out as approachable and professional. Callum Kerr visited my property to carry out a free survey, he was friendly and thorough and was able to answer my questions without defaulting to hard sell tactics leaving me feeling reassured. The process since accepting the quote from Callum has been seamless. The scaffolding company used were polite and respectful of my property and the solar panel installers efficient and professional. They helped to download an app so that I could track the electricity generated by the solar panels. This started on the day of installation and I have been enjoying the benefits since then. My project manager Kathryn Smith has kept me informed, guided me through the process and will soon confirm the date of the heat pump installation. I shall be back to write another review once the latter is up and running which I'm sure will be as positive as my journey so far. Watch this carbon saving space for more!
Carbon saving group installed my solar panels & battery to support my energy usage .Callum clearly explained how it would work and has been very supportive answering questions I've asked on my solar journey. The installation team were very professional with everything up and running in a day ! I’ve also had Callum come back and quote me on a Ev charger . Overall I extremely happy with the service I’ve received from the group.
Great experience with Callum so far. Clear explanations, fair negotiation, and a professional approach that reflects very well on the company. I’ll review again after installation, but based on the sales process alone, I’m confident and happy to recommend him. Looking forward to seeing it all come together.
We chose this company over cheaper alternatives largely because of Callum Kerr, who was excellent from start to finish—knowledgeable, approachable, and willing to help even after installation. Neil and the installation team did a very good job and were quick and efficient. However, the office support was a real letdown. An inspection appointment was missed after an email went into spam, and despite it containing important information that required a response from me, no one called to check I had received it. As there is no phone support from Friday to Sunday, (which makes resolving issues impossible over a weekend), I had to wait 3 days before discovering that the inspection had been rescheduled for the following Friday, (5 days before the install!) They also threatened to not remove the scaffolding, withhold certificates and SEG paperwork until they had received payment, an unnecessary threat owing to my having already paid in full, when I responded as such, it took days to confirm the payment and weeks for the paperwork to arrive. Leaving all the packaging for disposal wasn't reasonable, especially a large pallet that I had to cut up with a saw to get into my car for disposal, I wonder how older customers would have coped with this? The scaffolding contractors were the biggest disappointment: rude, damaged fence panels and a garden light, and left debris behind. Great solar install, but the office and scaffolding experience really spoiled it.
I highly recommend the whole process from start to finish .Callum was amazing in explaining how it works .The installation first class and after service excellent with Callum coming out and setting up our app with British Gas and guiding us with such patience he is such an asset to the company .We are 100/c happy
Efficient and effective
Fantastic Service, Callum could not have been more helpful from start to finish. Team in the office also brilliant. Many thanks.
A more knowledgeable, reliable and personable salesman is unlikely to be found. Calum made sensible recommendations, conducted a very thorough survey, designed a system and provided most helpful after sales advice. Thanks and well done.
Callum attended my house and explained the system and all my options . He was so knowledgeable and answered all my questions . Will definitely use the company and recommend talking with Callum if you’re interested in solar.
Callum Kerr came in person rather than look at my roof from Google Earth. There was no pressure and no underhand sales tactics (unlike other salesmen). He clearly knew his stuff. The survey he did was very factual (no over-promissing), and did his best to find ways to maximise the number of panels. He was also extremely patient in answering all my questions. It was a real pleasure to deal with him. He genuinely listened to my requests and where possible made them happen. The Carbon Saving group were very flexible to my needs, and true to their word and beat others on price. The panels and battery were installed in a day, and within weeks of agreeing. I'm extremely pleased with the installation and quality everything. Looking forward now to reducing my energy bills.
Thank you kathryn and the team guys worked till 8 oclock to make sure the system was finished before our holiday very much recommend clean tidy all over good experience would recommend
Exceptional service high quality products Sensational staff ready to work in any conditions Mike and the team were sensational. Highly recommended
From the start to the finish the thisncompnay really delivered Callum explained everything and the installers worked through this bad weather to make sure the job was done took some time to get the system online with wifi but all running great now looking forward to the savings highly recommend this company
Just had solar fitted from carbon saving group Tom came out explained everything left us with it guys turned up clean tidy very happy would highly recommend
I had my solar panels and battery installed back in June 2024 and was very pleased with the service. My app initially worked when the engineer was here but since then I have been unable to use my app. I have no way of monitoring how much my solar panel and battery are charging! Despite numerous attempts to request Carbon Saving to come back and sort problem nobody turns up. I have also spoken to Grren Energy who say speak to the installers. I have now configured and change so many times I don’t know where it’s going wrong. I feel Carbon Energy after care has been very disappointing. Still can get the app to work!!
Installed my house with all new solar panels and a battery I'm saving more money a month than what I paid out
My experience with Carbon Saving Group from the start was excellent. The people in the office were helpful and polite and made everything clear and understandable. All the work that was carried out was to a very high standard, I could not fault them and neither would I want to. Thank you Carbon Saving Group.
I was given this Company's contact details by the Renewable Energy Hub when I made an enquiry about installing solar panels. Carbon Saving Group Ltd designed and fitted the solar panel system on my new built property. The system is fantastically effective and with the excellent workmanship a perfectly stunning finish. I cannot fault the installation and helpfulness of this Company and its employees throughout the whole process. I can highly recommend them to anyone thinking of fitting a solar panel system.

Excellent and professional. Neil and Matt were great. Did I mention Matt was great too!
Great service from a very efficient company. I’m now very excited to start generating my own solar energy. Just 2.5 days to install battery, 18 panels and all the other components. Having done some price benchmarking I found Carbon Savings Group were the best for quality and value. Thank you Neil (at Carbon Savings Group) for a great job with the implementation.
Thank you for installing our Solar PV system and for patiently responding to our queries. Choosing a company isn’t easy with so many to choose from, as well as the multitude of products on offer. We chose Carbon Saving Group for their friendly, informative and professional approach as well as their range of products. 3 months since installation and we are really pleased with the performance of our solar PV system and battery. Thank you for providing a great service Carbon Saving Group.
Really helpful advice from a local firm with a clean and tidy workers and efficient service and helpful set up
Carbon Saving Group were fantastic and very professional , price and quality was the best on the market would highly recommend to anyone looking to save money on there energy bills
Great service, great company. Fast and efficient
Wonderful company, amazing customer service. 5 star ⭐️
Great work from start to finish was a little concerned at first but Tom put my mind at ease , installation guys where great very clean and tidy delighted with the result thanks to Niel and the boys who worked all day in the rain
We approached Carbon Saving Group with a specific specification of what we wanted for a 6kW Solar PV installation complete with 15kW of lithium batteries. Tom was the only supplier to actually come out to site and visit us before quoting, he was also one of the few who responded to our enquiry within a fairly short timescale, funnily enough he subsequently ended up getting the job! One of our particular concerns was the overall look and atheistic of the solar panels on the roof of our house. CSG were one of the few suppliers able to offer the GSE "in-roof" system, which allows the slates or tiles to be removed and for the solar panels to sit flush in the roof as part of it. We are very pleased we went with this system, not only is it watertight it also looks really good. Apart from the aesthetics we also had specific requirements regarding the hardware we wanted to use in the installation. CSG took all this in their stride...even though some of the hardware was new to them and outside of their normal scope, they worked with us and the manufacturers to get us the system we wanted installed. We are very pleased with the final outcome and thanks must go to the whole team, for putting up with us over over the job but especially to Neil, Mike, Kodi and Tom. Thank you!
Very friendly, professional advice and service from Callum. Answered all my questions and explained in plain english. Very informative.. Many Thanks for your help..
Many thanks to Callum Kerr who came out to do an initial survey and explained the various options to me. Callum was exceptionally helpful, easy to understand and professional. I also received a very prompt response to my initial enquiry. Very impressed so far.
Tommy was really professional and helpful, really good value for money and delivers on promises. Would really recommend!
Fantastic service, extremely professional and great customer service. Thank you to Tom for all his help. Definitely recommend this company.
Fantastic job from carbon saving group Had solar installed would highly recommend carbon saving group. Brilliant service from callum the surveyor visiting to kodi organising our installation and mike and his team doing a great job with the installation all kept to timing agreed got the job completed in 2 days even though the weather wasnt great they still cracked on with a smile on their face.
Solar PV installation - recently install a new system from these. Excellent service, clean and tidy from to start to finish. Highly recommend
Did not contact me as promised. I phoned again for another appointment and still no one responded
We had gas installation carried out by Chris and Bill this week. They were professional, friendly and explained everything that they were doing well. Did a fantastic job and cleaned up after their work. Would recommend your company
Been trying to reach them for 3 weeks but no one will ring me back to discuss my gas installation. At the moment they don't even rate 1 star. However to get this post online I have to give them a star!!
We have waited 3 weeks for an appointment. We were told the salesman would call half an hour before arriving. We have waited in all afternoon but sadly no phone call and no salesman. We even called and left an answer phone message to try and find out if they were coming or not. We had no response. This is completely unprofessional and a disgraceful lack of courtesy. It takes no time at all to make a phone call to cancel an appointment. It gives us no confidence whatsoever in this company. Edit. We have now received a call. A deeply apologetic salesman said there was a mix up with who was supposed to call and they are a small company who are very busy due to the government scheme.
Very unreliable for call backs. Didn't bother returning calls to give quote. Don't bother.
On 15/6/20 my new boiler was fitted . I have been thrilled with the service ! A very professional and remarkably “clean “ job . Everything explained in an easy to understand way and easy to use thermostat . I am so impressed with the service that I wanted to reassure others that this company is reliable and professional . They did everything from paperwork to installation doing exactly as described ... I felt treated with respect for every question I asked . The whole team have been fantastic !!Thankyou very much!!
Found your fitters Jack and Fish from Torquay who fitted our underfloor I insulation, two of the most efficient and and courteous men it's been our privilege to meet. They were the very the best advert you could have to promote your firm Thanking you. D PADDON

Fantastic Experience. Lovely gentleman turned up at my door, offered me a free boiler with a government incentive scheme. After looking into it a little further and to my delight, it turned out to be true. Within 2 weeks, I had my new boiler installed, FOR FREE... Excellent service throughout, good customer contact & care, qualified professionals used for the installation. Would have no hesitation in recommending them in the future.
