5/5

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.

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...

Avoid like the plague

I’ve driven 80k miles in 4 years in electric cars, and we all know the charging infrastructure is poor, but my experience at the Utilila Bowl in Southampton tops the lot. In short, the chargers card readers don't work, the OCR codes have been removed, the app doesn’t work either, you plug your car in and it says you can’t use that socket because it’s occupied. There is no customer service, they leave you hanging for 10 minutes then cut you off. If you ever pull up at a Carbon3 charger, just go elsewhere, it won’t work, you’ll waste an hour of your life and still end up going somewhere else. This is a company that does not deserve to survive

The worst company I have had the pleasure to deal with

PLEASE READ THE WHOLE REVIEW IT WILL BE TO YOUR BENEFIT This is by far the worse company I have ever had the pleasure or lack of dealing with In November 2024 we had heat source solar panels and boiler fitted by this company Before work started I was promised we would not be without hot water my wife and I are in our sixties and I am ill with disabilities They turned up on Monday ripped everything out by Tuesday the boiler did not fit as it was wrong size so new one had to be ordered radiators were wrong size new ones had to be made There begins a week of no adequate heating and no hot hot water for a week 2 kw heaters were offered but with countless workers in and out all day leaving all doors open there was no point wasting my precious money. Events continued to unfold work not done work not done properly trip hazards inside and out side for a disabled person who walks with sticks where they had just left unfinished work They even had the audacity to take all the scrap copper from the previous install including the boiler saying it would go to their Christmas party I complained to Breyer about all that had gone on so far who subbed the work to carbon3 and they Carbon3 arranged a lackey to come into my house to discuss “how they could put it right” Inc compensation They left and that was all that was the last I heard from them. This work was attempted by The Wrotham based depot This was not an isolated as they were working on the house next door whom also had a similar experience at the same time If I was the CEO of this company and doing these contracts for housing associations I would be getting my hat and coat and leaving the company If this is their normal standard of work and how they treat residents I would hate to think what problems lay in store for for thier installs in the future even to how peoples lives maybe put in danger with the workmanship I would never recommend this company to my worst enemy This is taken from their own website “ Expertise and Experience With years of experience in the renewable energy sector, our team brings unparalleled expertise to every project” “ Customer-Centric Approach We prioritise your needs and satisfaction, delivering tailored solutions and exceptional support throughout your renewable energy journey.” Believe me when I say they didn’t even come close Buyer beware if you are in Kent and are considering using this company walk away find a different more professional company to do a better install And leaving this company alone to fade into the history books as one of the worst companies ever CARBON3 YOU SENT YOUR EMPLOYEE TO OUR HOUSE TO SIT ON OUR SOFA TO ASK HOW CAN WE (CARBON3) PUT THIS RIGHT !!!!!!!!! NOT ANYBODY ELSE !!!!!!

Domestic Install led to no Bills

Carbon3 installed a 4.05kWp domestic Solar PV system on my house in November 2023 and my utility bills have been covered by the usage and smart export guarantee since. They have friendly staff and are easy to contact. Their sales team were prompt in their quotations and provided lots of system information. Their installers and aftercare team have been amazing as well. I would highly recommend using Carbon3 for Solar and decarbonisation projects.
