Zest Energy Ltd Reviews 

Fraudsters

I booked a solar installation with this company and paid a deposit. I then lost my partner to cancer. I informed them that i would not be able to go ahead with the installation and they stated they would return the majority of my deposit, minus admin fees. Over the course of a year they have repeatedly claimed they would return my money, but have failed to do so, including claiming that they have posted cheques, which have apparently been lost in the post. Avoid this company at all costs, I am now considering reporting them for fraud.

I arranged with Zest Energy in October last year a survey in regard to installing solar panels on my property. Despite being wary my worries where sharp and put to bed as the advisor was extremely helpful in talking and helping me understand the process. After deciding to go ahead with the company my panels were installed by there very kind and helpful installation team who carried out the work to a very high standard and were extremely patient answering any questions or queries i had and made sure there work area was immaculate by the time they had finished. Since using the company i have and would recommend them to anyone considering or interested in solar power.

My experience dealing with Zest has been a very pleasant and assuring service from the first call to my installation I recently had solar installed late last year and contacted zest in regards to adding a battery storage to my system. The advisor who came and surveyed my property was extremely helpful in advising me if the best scenario for my system and explained in great detail about the systems the company offers. My installation went without a hitch the installers where very professional and took there time in explaining how to work the system and were very patient with myself. Overall I would highly recommend Zest after dealing with other companies previously I couldn’t see myself using anyone else now.

sales man pushie saying you have to take it for the price he gave me and said the other companys i got a quote from are not to be trusted to do the job he would push me more to take the panels and batteries from them and i just said no

Great customer service explained everything clearly, happy with new solar panels and battery installation, Job was efficiently done by friendly polite workmen.

Mark and Billy installed our solar panels and battery storage this week. The process from start to completion ran very smoothly and professionally.
For competitive pricing and high quality installation of a excellent system I recommend Zest.
They arrived when they said they would and worked tirelessly until the wind hampered the final install. They returned first thing next day complete the job.
Mark showed my how to work the app and what to expect from the system.
Very happy

Terrible. Installation of electrical aspects was good but roof work hopeless. 2 weeks after “installation” found a disconnected panel just left on roof! Panels also not aligned to South.
On evening of installation had foul mouthed Zest director demanding immediate payment.
Agree negative stars would be appropriate.

Had freezing rainy weather the day the panels went up. Didn't phase the team. They worked really hard and efficiently all day. Solar panels are huge when you stand by them!
Polite, pleasant and hardworking.

Good and complex planning and time taken to explain the procedure. Good job completed by workmen who turned up when were arranged to. One outside and one inside installing the electricals for the panels. Completed it all in one day and took away all packaging and rubbish leaving home tidy.

Terrible company, poorly designed and installed, slow to organise remedial work, still waiting on refund that was agreed to in June to be paid. AVOID at all costs

We paid a deposit of £670 for a battery storage and inverter installation. Their salesman assumed that this could be located in the garage and after a lengthy presentation and advice to sign up now for a deal of a lifetime we signed his contract and paid the deposit. It subsequently transpired that it could not be fitted in the garage unless we ran a cable the length of the house and through the garden.Alternatively their engineer suggested siting the equipment in a small hall cupboard. We were not happy with this and cancelled our contract on the basis that we had paid towards a straightforward installation in our garage as advised by the salesman. I endured three extremely unpleasant phone calls from staff in their office when we emailed to cancel the contract -then I was warned that I had incurred costs - it seems I had to pay£500 for the engineer’s visit ,delivery of equipment and even the salesman time ( when he sold us a system that couldn’t be fitted in an acceptable location).
Sharp practice, pressurised sale’s pitch, inaccurate information and unpleasant staff sum up our experience of this company . Be warned Stay clear.

Second time using zest energy. First time was just solar panels. Second time ASHP and battery storage for my solar. Can't praise them highly enough. Work done to an extremely high standard. I had extreme pleasure to deal with Sean as the sales man. Helped me through every process. The installers did a very neat job and tidied up after themselves. Can't rate them highly enough

The keep phoning and cancelling appointments I came home early from work just to meet the consultant
and both times they broke down
very unprofessional

The Zest Energy engineers made the installation of my electric car charger a seamless experience. Their expertise was evident, ensuring a quick and efficient setup. The entire process was hassle-free. Thanks to the Zest Energy team for the installation. It performs exceptionally well. I’m enjoying the convenience of our newly installed electric car charger!

Wonderful experience with Zest. Great product (Zappi car charger) with very fast installation by friendly and knowledgeable fitters. Everything has gone very well and I can't recommend them highly enough.

Just had solar panels and battery storage installed. Zest did a good job of communicating and installers were polite and efficient and left the place spotless. Very glad Ive made the installation. Zest made things very straight forward.

ZEST ENERGY ARE A VERY GOOD COMPANY AND HAVE BEEN VERY HELPFULL AND I RECOMMEND THEM FOR SOLAR AND BATTERY INSTALATION. THERE FITTING TEAM WERE EXCELLENT AND FROM THE START SALESMAN PAUL WAS VERY HELPFUL. FROM FIONA HAY DALGETTY BAY

Zest Energy installed solar panels and a battery storage unit at our premises, have no issues with the performance of the equipment. The installation of the panels was fine. Although the wiring is not run in conduit just tacked to the wall, which is a concern.
My main complaint is the battery unit which was installed in our garage very close to our kitchen door. I had agreed the wall to be used but not the location on the wall. I contacted Zest Energy who agreed there must have been miscommunication and agreed to relocate it. They have now gone back on this and say I have to pay for this work to be carried out. The unit does not have the clearance around it as per the manufacturer's guidance. Again, the wires are tacked to the wall and some of which is hanging loose. They will not take my calls or answer emails. Very disappointed in their response for work that cost approximately £18000.00. I believe the main reason the battery unit was located in the wrong place was that they have not invested in the correct equipment for lifting the unit into place. Definitely cannot recommend this organisation.

Installation was fine and the system worked well for a time. My main complaint is that l was not told that they did not have MCIS Certification so I can’t export surplus energy. The app on my phone even says I should be able to get over 18p per KWh but I receive nothing. Since installing the panels I have had a few occasions to call for after sales service which has not been forthcoming. I recently called an engineer from another company suggested by Solis, the manufacturer of my inverter who found a number of faults with my system including that the inverter and battery were installed in a cupboard which did not allow sufficient ventilation and the wiring used was too light for its purpose. He has suggested that to make it safe the inverter and battery should be moved to my loft and higher rated wiring should be used

Got my solar panels fitted in December. I have to say that so far the system has worked really well for me. However in hindsight it has become known that I could have received an interest free loan from Home Energy Scotland to help with the cost. The salesman did not make us aware of this ? I am getting further renewable energy measures done to my home and help with costs via Scottish Government grants I am advised that Zest should have provided me with a up to date EPC as the energy efficiency status had changed with the solar panels. I did not receive this?
Also we had a few problems to start with and we found it extremely difficult to contact anyone My concerns are with on going customer care should any future problems arise.
