Zest Energy Ltd Reviews 

Great speedy service did exactly what they said and the best price

Everything done quickly and efficiently. With really nice customer service to answer any questions you have, they were very helpful

At very short notice they helped us out with inset solar panels and batteries. We had them installed over 3 separate days as they came and installed after the roof was ready.
From the sales guys to fitters and the boss man very accommadating. Highly recommend them.

The team were so helpful in guiding me through the entire process, and installed the system as promised on time and tidied up behind them, so please with the company’s professionalism.

Zest energy were very quick a bit too quick you hardly had time to think about what you were getting into .They we’re very and helpful apart from the boss who wanted paid before the man got of the roof .we did have a slight miss communication.but all done now thanks again

good customer service from agent to engineers

A high quality and excellent solar system was installed in a very professional manner by the installation team.
With particular thanks to Chris Johnson, the installation team leader, who gave very good advice and general tips on the system and went that extra way to make it all work.
Very good communication from Archie Reilly, the customer service manager, during and after the installation.

Unfortunately, due to my impaired eye vision, I had requested several times to have large print outs of the proposal and contract to be sent to my home address, but this never happened but stated in the contract. The proposal was well below my expectation and critical information for me was missing and there was no pricing breakdown.

There were initial poor and miss communications with the salesperson, surveyor and Zest team members and resulted that the end product did not fully live up to my expectations. Issues with the location and orientation of the panels. The solar hot water interface that was installed was very disappointing and well below what I was expecting. The system cannot be monitored and controlled, though was discussed initially. I would have been happy to pay the extra difference if money had been an issue. Now, I need to change out the interface at a great and extra cost for a better and more advanced unit. It’s more than likely will not receive any compensation.

Discussed with the salesperson for a possible expansion on the original proposal by adding additional panels and a battery in order to maximize the the energy production. Unfortunately, I never got any further details and feedback about this on costs, possible saving and if this is worthwhile.
I am still planning for an additional battery and panels in the near future but would request technical advice and not dealing with a salesperson. Though would expect an acceptable proposal with price breakdown from Zest.

Zest Energy was recommended to us by a friend who is an existing client of the company. Up to date, there has not been any communication from Zest with her related to the “friend’s award “of £400.- and this is now nearly 4 weeks ago since installation and full payment from us. Her contact details had been given twice to the salespersons.

The sales man knew his stuff. The office staff worked hard to get everything done quickly and easily. And the installation was simple and easy. Everyone was pleasant and easy to talk too.

The quality of the work seems excellent and the effort to find the best solution for my situation was great. This of course was necessary as the real challenges were only identified by the technical workers when they came on site to fit and not by the salesmen- ideally situation and proposal should be seen by those fitting it before contract// costing agreed.

Very.
Experienced

From the initial proposal/quote to installation took 2 working days. Installation was done professionally and a tidy job. Works as described and communication throughout out was excellent. Good job all-round.

please do not put any effort or time into this company. i’ve worked for their phone lines and they do not pay their staff and refused to acknowledge what they’re due. avoid at all costs

Great sales experience from start to finish. Very informative and educated sales team, including the office support team, for follow-up questions and queries. They explained everything in full detail, including potential savings to save money and get a great return on my investment, so from my experience i would recommend Zest to anyone wanting to invest in solar panels and batteries to save money. Happy customer

Cannot recommend enough.

Was met with amazing customer service and even better results. Thank you to the team and I will definitely be recommending to people I know.

Amazing service, in and out quickly

Amazing service. Would highly recommend the team at Zest. From start to finish we had fantastic service, great communication and a truly professional service.

Quick installation and great customer service! really happy with this experience

Excellent from start to finish. The solar system was installed quickly and fitters cleaned up after themselves. My electric meter has barely moved since, saving me a small fortune. Thank you, Zest.

Fantastic experience from survey to installation. Installers worked extremely hard to complete in one day. It’s made a massive difference to my bills too, which has been great to see. Would not hesitate to recommend.

A little bit pushy promise of a free inverter did not happen according to the paper work everything else first class
