All that has been done from sales to installation could not have been done in a worse way. The salesman Nigel happily took our deposit but after problems started was unobtainable. The system was fitted in April 2022 and I have never received a penny from the grid for exported electricity. I paid for a 7.2 kw system but have only a 4kw inverter. I found it impossible to get this company to honour their commitments. I have had the system checked and the battery storage placement is dangerous . There appears to be no regulation in this industry so nobody is willing to put these people out of business . Do not speak to this company and at all costs do not let them into your home. Solar does work but this company gives it a bad name. We need a control over this industry to insure fair play for the consumer. The cost to put the system right is between £8000 and £10000 . Although the system was fitted in April 2022 it is an ongoing problem.

I worked for this fraudulent company one year ago. And like others who have been in the same situation have still to be paid. The management are bullies and who prey upon the vulnerable and belittle the staff as well as the customers… STAY WELL AWAY!! Do not use this company.. charlatans!!! One Star ⭐️ too many imo

Got a cold call and did a short survey. Told the sales rep I was only tentatively interested but as I would be at home the following day, I was happy to let someone come and do a survey. Got a further call the day of the survey to check if my wife would be here. Told them she was busy and wouldn’t be here most of the day. This led to attempt to pressure me into changing the time so that she would be here. I told them to forget it. As others have warned, this company seems to use high pressure sales techniques. Will not be using them in the future.

unsolicited sales call , demanding salesman comes to my property to "survey" Told them i would happily speak to a salesman but they would not accept that .

Avoid this company at all costs. They were not registered with MCS when they installed my solar panels in July 2022 but promised that they were registering and could back date my certificate. They then informed me that as they only registered with MCS in December 2022, they cannot provide me with a certificate which means that I will NEVER be able to claim any money down for excess energy going to the grid. I agree with all the comments made - appallingly bad communication, they do not comply with their own advertiased complaints procedure and I have written 3 formal letters of complaint and have had no response to any of them.... and as for getting a call back when you phone - forget it. Do not use them. I wish I had researched better when I engaged them last year.

Since last August 22 the Solar Battery 5.8kW installed by Zest Energy in February 21has not been functioning. We have had numerous calls to Zest, have been promised all sorts of explanations and promised to have the problem resolved. Also the battery has a 10 year guarantee . However after we felt we were just being fobbed off, a letter from our solicitor was sent to Zest in an attempt to get a resolution to the problem. We have a had no response at all. This has been a very upsetting, and disappointing experience with this company, We are stuck with a battery doing nothing.

been having problems for a while system not working been complaining for a month no further forward all I get Is the person you need to speak to is not here i'll get them to call you back still waiting now they're not even picking up when I phone I have had several upgrades done by them major problems if anything should go wrong as for service there hasn't been any Avoid do not use today I went up on my roof to see if there was any obvious issues with the solar panels was surprised and annoyed to find all the micro inverters laying on the roof not a single one has been attached to the frames can’t complain as they no longer pick up the phone

If I could choose zero stars I would...cold calling, pushy sales, prey on elderly and vulnerable, charge huge amounts then drag their feet when things aren't working as they should. Avoid Avoid Avoid
