Review Summary for Carbon Saving Group Ltd

Carbon Saving Group Ltd. customers frequently commend the politeness, efficiency, and knowledge of their installation teams, often highlighting individuals like "Callum" for their valuable, no-pressure advice during the initial consultation stages. The company frequently receives praise for prompt service, clear communication, competitive pricing, and solid, professional installations of various energy-saving systems including solar panels and heat pumps, with some reviews also noting effective after-sales follow-up regarding tariffs. However, a significant concern arises from a minority of reviews detailing issues with underperforming systems, incomplete installations (specifically an omitted earthing rod), and poor, unresponsive aftercare, where communication is inconsistent and meaningful help is lacking once payment is received. The company appears well-suited for customers seeking a range of home energy solutions, from solar panels and heat pumps to insulation extraction and central heating, particularly if a smooth installation process and helpful pre-sales consultation are priorities. Before ordering, prospective customers should explicitly clarify the scope of the installation, confirm all components will be fitted on the day, and establish clear, documented expectations for after-sales support and performance guarantees, especially given the mixed feedback on post-installation responsiveness.

Excellent service, prompt, clear communication, well organised and the software is easy to monitor so I can see how the panels are doing. I highly recommend Carbon Savings Group

I, like many other people, saw a piece about 'free solar power installations' based on what transpired to be false promises. However, one of the many contacts I received was from Callum Kerr and he explained the problem about the false promises (designed to collect data then made availble to a range of solar energy installers), did not pressure me (unlike some of the other responses I received) but delivered three preliminary options based upon our dialogue. Based upon his valued input I did not go ahead with any supplier but were I to change my mind - he would be the person I would call.

Engineer turn up on time with all equipment and install in hours. Ran me through all settings on computer and was happy with advise. Very happy with price and work.

I regret choosing Carbon Saving Group for my PV system. Not only has the system underperformed from the start, but the installation wasn't even completed on the day. They forgot to install the earthing rod, and I had to chase them afterwards to come back and finish the job - something that should never happen with a professional installer.Support since then has been just as frustrating. They respond to emails when they feel like it, and when they do there is no urgency or meaningful help.This company might be fast to take your money, but their aftercare is poor, communication is inconsistent, and they clearly don't prioritise customer satisfaction once the install is done.Carbon Saving Group talks a good game but in reality, you're left with an incomplete, underperforming system which you paid thousands of pounds for, and a company that doesn't stand by its work. Very dissapointing.

Was recommended to use them, loads better than more expensive national company. Prompt fitting when we decided to use them. Really good follow up, especially with finding better tariff - thanks Callum!
