Zest Energy Ltd Anmeldelser 

All was great to start with. The salesman came out and we talked about what I wanted. We discussed my options. I decided to go ahead with the installation of the solar panels,a date was agreed and everything went well with the installation. Then they were meant to come out and talk me through the system and check everything was OK, as I had to work the day of the installation. The salesman and I arrange another day, but he never turned up and I haven't been able to get hold of him since

Excellent service, from sales consultant, installation and after services everyone has been friendly, professional and very helpful.

The whole process was very quick and up and running with in a week. Very good service.

The solar panels are now providing all of my electricity and I am even exporting to the grid.

I can't recommend Zest Energy enough, fantastic service.

Delivery and installation exactly on time.

William, the installer, and his assistant, were very helpful and informative about the product.

Great communication with the team, both during and after installation. Personalised service to meet our needs. Great product and competitive price. They went that extra mile to enable a smooth export with power company.
Highly recommend this team.

Sales rep was friendly and patient.
Delivery arrived at 9.30am again very polite and efficient. Roofer and electrician arrived 9.45am.
Job completed in 6 hours.
Very little disruption to our day.
Archie in office will help get us up and running as a supplier.
Inverter and battery were installed inside the house which was not preplanned however all worked out without much disruption. We will recommend Zest that our friends.

Engineer and installation great. Aftercare good so far. Don't believe everything the salesman says without thorough checking.

Thank you for your work

I couldn't be happier with the whole experience from start to finish. The sales rep was brilliant – there were absolutely no pushy sales tactics, just honest advice and plenty of time to answer all my questions. They really listened to what I wanted and customised the system to suit my home's energy needs rather than trying to sell me something I didn't need.

The installation team were fantastic as well. They kept me updated throughout the process, communication was excellent, and everything was completed to a really high standard. They even set up all the apps and monitoring for me before they left, making it really easy to start using the system.

The after-sales support has been just as impressive. Around three months after the installation I had a query involving my utility company, and they responded quickly and helped get everything sorted without any hassle.

Overall, it's been a great experience from beginning to end. I'd happily recommend them to anyone thinking about getting solar installed.

Have used zest before to fit my solar panels
So increasing my battery storage it was a no brainer to return to zest
Great customer service.
Sales guy knew his stuff friendly
No real pressure but do push for a quick decision..Quick turnaround and great installers knew their stuff and sorted a few issues promptly

Installation good leaving the house door wide open most of the afternoon was pathetic and after sale information still waiting

Fitter/electrician polite and informative guy considering the outlandish location always arrived maybe a little late. Problem arose regarding my electric car charger not working when battery storage system in operation. This took some time to resolve but eventually he overcame the matter.

A number of years ago we had this company do some work for us. We were quite satisfied at the time with what they actually did. Ever since, though, we have received frequent, unwanted calls trying to sell us things we don't want. They have repeatedly ignored my requests to take our number off of their lists and not phone again. Even when I block their number, they change to using a different number.

My father was provided with a highly misleading quote for a new battery to upgrade from 6kWh battery to a 9kWh and retaining his existing solar panels. The quote showed projected net savings over 20 years of over £19,000. But the savings were based on a house that had no solar or battery storage available to them when Zest had installed a the existing system at my fathers property just 4 years earlier. It was only by luck that I was able to review the quote before installation took place and inform my father that this was not worth the paper it was written on.

Subsequently it has taken Zest approximately 50 days to refund my father his deposit, and only after the threat of legal action. The guidelines they say that they work to states that refunds must be paid within 14 days.

Job done well and at agreed time. Friendly workman.

Terrible experience. I was stupid enough to give this company a second chance. What a mistake
The company director is arrogant and self entitled. Would not recommend this company to anyone
The guy who did the installation was a professional guy.

I was told the new battery would make my electricity cheaper - since the new batter was installed my electricity has doubled, even quadrupled yesterday so what I was promised has not been delivered . This was an error made by the Company which I picked up on. This work should have been 2nd checked by a Supervisor/Inspector and should not have been picked up by me. We were also advised to change to a specific Tariff which corresponds with the new Battery. My Supplier has advised me this Tariff is Blocked and not open to Customers due to Volatility so that raises the question has this been a complete waste of £7,700. In my line of work if I make a mistake that is costly to the Customer/Client then there are rules in place which states Compensation must be paid by the Company to the Client/Customer ..

Having bought my
First battery was a good investment and all went well with a slight delivery problem. So far so good.

The representative who came first of all was pleasant and explained everything.The engineer who installed the battery worked extremely hard in atrocious weather and again was very pleasant.
I do have a problem of the disposal of the old battery with no communication from you as to who and when it is to be picked up.

Awful, connect charger took 40 quid x3 times and each time never charged gave up and went some were else. No reason for it to fail 3 times but yet they pre auth amount is £40

If you want weekly phone calls to chase a refund they should have issued within 14 days this is the company for you. Even though they have a legal obligation to refund within this timeframe I have had to call 5 times to chase £750 owed to my 83 yr old father in law. This is the second bad review I’ve written about this company and unfortunately my father in law trusted them a second time. I managed to intervene before the work started but now I’m spending my time chasing a refund. The person who deals with it was away and only back one day. I left it a week and called back, he’s gone away again and it seems he’s the only one person who deals with these things and cannot work remotely like many of us do. Avoid at all costs unless you enjoy horrendous customer care.
