Zest Energy Ltd Avis 

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.

Avoid this company at all cost.
We had solar panels, inverter and a battery system installed last November. When we were sold the system, we were told by the salesman and the electrician that ZEST would do all the paper work and we would receive payments for any surplus energy produced and returned to the grid. This did not happen as ZEST were not registered as certified installer with MCS at the time of installation and therefore none of the electric suppliers will pay for any surplus supplied to the grid unless the system is installed by a certified company. The system works and is saving us money but we have some serious concerns with the installation and ZEST refuse to respond to any of our phone calls or emails.
We feel that we have been scammed and would recommend that you avoid this company and go with a reputable installer that is MCS registered and gives a quality aftercare service.

Great company had no problems from start to finish salesman was great explained everything perfectly and the installers done an even grear job when putting my panels on my roof would highly recommend zest energy

Long story short. We had a system installed by Zestaround June 2022 and Initally it looked great and was working well.

Then we realised that we were drawing from the grid after our output reached the inverters maximum of around 3.6 kw. Even though our panals were producing way more solar energy than this.

We quickly spotted the issue (my wife is an engineer). Zest had Installed a diffrent inverter than the one we had ordered and agreed with the sales rep, John Pears.

To be fair to John he's a lovely guy and tried to fight our corner saying that it was the 6kw output inverter that we agreed on. The idea being that we would be able to charge an electric vehicle from the solar output.

John is no longer with Zest energy stating that there was a lot of problems and that there after care for customers was poor once they had your money adding, I was not the only customer who was having similar issues.

After a lot of back and fourth Zest agreed to the "mistake" however stated that the 6kw inverter was out of stock and would only become available in the fourth quarter of 2022.

Anyway that date as come and gone and we have recieved no further communication from the company. Which we fully expected.

We had come to the conclusion that we had been scammed and we would never see the inverter that we had actually ordered.

Tonight we were reminded of this when we found one of the plastic cover plates from the panals on the front lawn. Luckily it's summer so the hole in the roof that should be protected by the plate can be replaced before the wetter months start and water ingres has a chance to enter our property.

I noticed that Zest have been responding to other complaints on here so this is my last gasp at any sort of resolution.

We have since drafted a complaint for the financial ombudsman regarding the issue this has been fully suported by John, we have yet to submitt this as we hoped a resolution from Zest may have been forthcoming.

It's a real shame as Zest has the potential to be a great company in its field. However the lack of customer aftercare appears to be really damaging their reputation. When you spend large sums of money customers rightly expect to be looked after and Zest don't seem to care about that.
