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.
