Carbon3 Ltd has mixed feedback. Two reviewers praised the staff: one described Isaac Barnes as friendly and hardworking, and another called staff friendly and helpful. One customer said a Solar PV system installed in 2022 had cut their utility bills, with export earnings covering their electricity bill and more than three-quarters of their gas use, and praised the EV team as knowledgeable and helpful. One reviewer reported that all five electric car chargers installed at their block of flats were out of order for months, with little or no change across repeated updates, and said the company stopped responding to emails. Another reviewer said the company turned up outside their building and started surveilling them without notice or permission.

Carbon3 have been coming to our property for over 3 years now. Usually engineers come with a temporary fix and promise to come back later to properly fix and never do. However today we had a visit from Isaac Barnes. He went above and beyond with taking care of all issues without even asking. Very friendly hardworking chap who actually cares. Massive asset to your company!

Don't waste your time with this people. Installed 5 electric car chargers outside our block of flats and all 5 are out of order for months, they are aware of the problems yet no one fixes anything. In fact they even stopped responding to the emails. Absolutely disgraceful company. AVOID like a plague! Update October 2023: Another 3 months have passed and all 5 charges still broken. Carbon3 reached out to me to remove my review as it may be detrimental to their business, yet had no time to fix the chargers. BAD is an understatement. Not only I will NOT remove this review, I will keep updating this review as long as it is needed to get it fixed. Update November 2023: All chargers still broken. Update December 2023: One charger works occasionally Update January 2024: Still no change, 4 chargers out of order, one charger works intermittently. Update February 2024: No change, chargers still broken 👎 Update March 2024: No change, chargers still broken 😒 Update April 2024 All chargers still broken Update May 2024 All charger still broken, what a joke of a company Update June 2024 Chargers broken, no change. Safe to say it's a company to AVOID! I'm tired of updating this review as we are getting nowhere, save yourself a headache and look elsewhere...

I used Carbon3 to install upon my domestic property in December 2022 and the Solar PV system has transformed my utility bills. In fact, my export so far this year has exceeded my grid usage. The Smart Export Guarantee has paid for my electricity bill and more than 3/4 of my total gas consumption this year. I would highly recommend using Carbon3 as a provider of low carbon technologies. I found their service levels first class and particularly found their EV team both very knowledgeable and helpful with their advice.
