Harrassment repeated!

I disliked the speed with which I found myself bundled into this purchase.
I should have requested and got a better payment scheme.
I have not had a chance to try out the system.

Dear Mr Johnston,

Thank you for your feedback. We’re sorry to hear you feel that the process felt rushed — that was certainly not our intention. You first contacted Zest Energy in 2022 and we’ve provided several quotations since that time, including discussions around battery storage options.

Your recent order was placed on 14 October, and our installers attended as arranged. The payment terms were clearly outlined in the purchase contract, which you accepted — with payment milestones based on deposit, delivery of goods, and final payment upon commissioning.

Unfortunately, we’re unable to deviate from those agreed terms once installation is underway.

We’re confident you’ll see the benefit of your new system once you’ve had a chance to use it, and we remain available if you’d like to discuss any aspect of your installation or payment plan directly.

Kind regards,
Zest Energy Ltd

Initial contact was professional and friendly, The salesman’s advice given was to the point and informative, any questions was answered thoroughly. The best thing was for me he didn’t push anything.
Would like to add the fitters were excellent and knew there job well and explained things as they went along as I had few questions. Would definitely recommend.

The 3 workmen were very efficient and most of the work was completed yesterday. Only needed one more solar panel on my back roof and he also replaced 2 slates that had slipped at the front and repaired 2 chimney breasts which were causing leaks in both upstairs bedrooms by the end of the morning today.

The whole experience was quick and efficient from start to finish.
The sales person answered all my questions and provided all the information.
The installation team were excellent and showed me how to get the most from the system through using the app.

Hi William,

Thank you for taking the time to leave your feedback. We’re sorry to hear there were difficulties reaching us at the time, and we agree that waiting on a promised call back is frustrating. We apologise that your experience fell short on that occasion.

Since then, we were pleased to carry out a further installation for you, and we hope this reflects a more positive experience than the one described above. We’re grateful that you chose to come back to us, and we appreciate your continued business.

If you ever need support with your system in the future, the quickest way to get in touch is through our office on 0131 467 3257 or at info@zestenergy.net, as these channels are monitored throughout the day.

Thanks again for your feedback.

Kind regards

i would highly recommend Zest energy for solar panels

They fitted it in one day and the staff were hard working and very polite. They were very clean and left my house and garage very tidy . The scaffolding company removed the scaffold a few days work was finished but they were very quick and quiet removing all the equipment.

5 star customer servic

Had my solar system since 2022. Hadn't realised I wasn't registered to send my energy back to the grid.
Archie went on the case and was resolved by him. Even after 3 years had passed. Great customer service! I would recommend to anyone looking for a solar array.

Fast efficient service

From the initial appointment to the installation and after care I couldn’t be happier with zest energy. Highly recommended. Cameron who visited our home to do the quotation was very helpful and I even threw a couple of questions he was unsure of and he very quickly got answers for me. Archie who was calling me to keep me updated with the installation appointment and again couldn’t have been more helpful with info I required. And Craig the installer and his team were so methodical, clean and tidy and got the job done a high level of satisfaction even pointing out an issue made by a previous seperate company that installed my solar. Very happy with the service from start to finish.

A very knowledgeable salesman Cameron who went the extra mile for us , thankyou . The engineer Chris could not have been more helpfull or polite to ourselves and was very tidy in his approach to the job in hand . My cupboard was a very tight fit for all the stuff and he still managed to get in beside it to fit and wire all components. Thankyou . Office staff have been great too . First class service all round .😀

Trustworthy Company

I was very skeptical about going ahead with this investment, however Cameron Milne, the salesman, was not at all pushy. Instead he took his time looking at all the possibilities that would result in our electrical bills being covered by Solar panels.
He was very patient and answered all of the huge number of questions I had about the system.
He was genuinely invested in the benefits of Solar Energy, without pushing me to accept a deal.
Overall I am delighted we went for this and as soon as the panels were installed, I could see the massive energy benefits.
The accompanying members of the team were also very knowledgeable and did a superb job of installing the entire system.
I would most definitely recommend Zest Energy to furnished you with the facts, figures and installation of Solar power.
