Really keen to take my money - battery installed fairly quickly however it turns out they never gave me the correct app for my phone so I wasn't aware that the battery obviously wasn't working correctly. When I noticed there was not light on (in attic) I contacted them. Several phone calls later - being told by young voices that they were happy to "reach out" to me and would inform the manager I eventually emailed - that was August - an engineer came in December and said "oh its not working" - I am still waiting - the last response I got was that they were trying to contact the manufacturers - happy to take the money but not to help after - worst company I have dealt with

I was sold a complete solar set up during which time my order was changed several times until it was completely different. The survey was ok but the installation was a nightmare. Holes were knocked in our walls and left unrepaited, cables tackled onto our Victorian woodwork, piles of rubbish left at our door. Worst was the staff the agent only spoke to me to alter the set up and increase the price then when I texted him to complain about constant delays he lied to his manager telling him that I had called him three times on Christmas Day which I had not. The manager then became aggressive and started shouting at Me. As a registered disabled pensioner I found extremely disturbing and reported it to the police. I agree with many of the other comments that this company should be avoided.

Zest Energy just cold-called me on home landline (breaking Telephone Preference Service regs). Offering solar panels. First introductory call (07384546041), then second call to discuss survey (07554431663) then third call (01314673257) from female sales manager to confirm survey visit for early afternoon today. Apparently my wife must be in the house with me - WHY ? "company policy and we want to impress you so that you come back and deal with us again" WHY ? "we want to tell you how the system works" for an hour !! Sounds like a hard sell approach. Sales manager was pretty abrupt on the phone.

Awful experience . Salesman was ok until his line manager phoned him up at told him that if we had applied for the hse loan to not waste anymore time and to leave this sounded very offensive and in appropriate . The main boss phoned me 30 min later to tell me a different story . But he is looking into it . This has put me off dealing with them ever and very wary of sales tactics coming to my house . Terrible company to deal with but at least never had to give them any money like others review i read . Take care

Terrible company still waiting for them to finish the job started 2nd of July 2022 The phone number is a call center they don't get back to you for days Will not reply to emails Arrange for engineers to come and they don't arrive at all Job was rushed and as of today still not complete I have taken 4 data off for them not to appear I could nor recommend them at all

Further to my last review on here, 9 weeks later and am still no further on! 1 visit from engineer to be told we need a new invertor! The owner messaged on my review asking me to email and he would look at it as a matter of urgency! I did and no answer! That is 2 months and 1 week of our guarantee gone!! Absolutely disgusted with this company. Worst purchase ever!!!

DO NOT Trust this company!!!!! They will come out and hit you with the old double glazing scam pressure tactics “of only 1 left!!!” “the price goes up next week!!” Etc…. Etc… However we did pay the deposit in good faith. This was a huge mistake as the company will not now communicate or return calls! We have sent a cancellation letter by recorded delivery and now need to take further legal steps to recover our £1000 deposit. This has totally put us off having a solar package installed in our house if this is how they behave.

Zest Energy installed a solar panel and battery storage at our house in early July. They had not come back to finish off the job a number of weeks later and we had to chase them up to do it. We are still waiting on them to complete the install completely and are not answering my emails. I would suggest you avoid this company as they are very unprofessional.
