Zest Energy Ltd Reviews 196

The solar battery installer arrived around lunchtime and worked steadily til the job was finished mid affternoon. He was polite and efficient and left everywhere he worked very tidy

Quickly installed. Area left tidy after the work was completed.

The men who fitted the battery charger were very good workers and fitted inside a cupboard which I asked them to do.

No problems with installation all set up now with the octopus agile so lookinf forward to cheaper electricity

Installation was ok but level of detail to quality of work could have been better as had to tidy up some of the fitting to prevent water ingress to house and wiring. Install felt rushed and generally was left with area to tidy up.

The new battery was fitted on Wednesday 22 April. There was a faulty component, I was told the replacement would be fitted on the Thursday or Friday. The last I heard was the component was out of stock.

Very pleasant engineer
Job done efficiently, leaving no mess

Good service good company everything was great setup. Works great from the first day of installation. The same when we upgraded the battery size changed over quite quickly and working great. I am glad we went with zest energy Ltd. Thanks Mr John Williamson

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. However they turned up and made the changes needed pretty quickly so we feel a bit better about them now.

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
