Zest Energy Ltd Reviews 187

Great company great service had solar panels and battery supplied and fitted 16 month ago and just recently but in a larger battery and was done on a house with a flat roof and has worked great since day one of fitting thanks.

the new kit was put in a position so that we cant open the freezer properly, stuff was taken off the walls without asking us and a lot of rubbish was left behind. We were told that someone would come fix things this week but so far all we have had is one contact saying they were trying to find someone. Also we were promised that someone would come to help us change supplier so far that hasn't happened either. Really fed up.

Great service very helpful staff and excellent insulation

Installed professionally.

Sold me what they intended to sell me after calling in for a health check. The upgrade is great and a vast improvement on the 5kw battery that never worked despite repeated request to effect a fix. Once contract was signed and they had my money, I never heard from them only the contractors doing the work and they were great.

My experience over several years of working with Zest, has always been excellent.
In this recent contract, their performance was again executed promptly and efficiently in both the installation and follow-up procedures. Zest Energy are a good, reliable company to work with.

Workmen were efficient & tidy & and we are pleased with the finished job

The installation was pushed to get done quickly and they were very efficient and tidy. But nobody told me how long it would take to get all the paperwork to allow me to use it. It's almost 6 weeks already. 19/ 03/26

The Purchase and installation was good so far still require another part to be fitted which had to be ordered up, Zest have promised to replace tiles that are broken due to the brackets for solar panels ( note our tiles are quite fragile) , have now supplied a MCA cert so we can now get money for any power that goes into the grid, the 4 Stars are due to broken tiles

All staff I dealt with were helpful and knew their stuff.
This company has been a treat to deal with. After a bad experience with another company, I was a bit hesitant. In the end I am glad I went with them.

Many Thanks Guys

On time arrival and excellent engineer. Very efficient installation.

Came when they said they would. Quick and tidy installation.

Prompt and efficient service. Quality technical support in plain English without being superficial. Prompt, considered, and considerate email responses.

All staff were very helpful at all stages. Engineers who did the install were fantastic, office staff were wonderful. Communicating efficiently and helped clarify matters that I misunderstood

Installer was very good, but when it is linked up to computer there is no information as to what it all means. For older people I think it would be an idea to have a manual as to what all the readings mean.

Good professional job nice staff to do the work clean tidy job

I was adamant I was not getting a battery but when a Zest agent visited, he quickly covinced me I was wrong and am so glad.

Was sold £6000(approx) GivEnergy battery, was told the energy provider was compatable with the deal & after instilation discovered that they had stopped the deal before it was sold to my elderly parents.
I feel this is totally inappropriate & personally feel that my parent were scammed.
