The roof tiles are lifting where the solar brackets were installed and it seems that a tile may have been broken as there is part of one laying nearby. There was very title support after installation in regards to SEG and EON offered a tariff which they later said they couldn’t supply. Tariff and SEG issues are being sorted. I still have to follow up on th installation problems.

The Solar Panel installation in January was not without its hitches, and took longer than originally advised. However, now the system is up-and-running, I am happy with the finished product. During the problematic January installation, I was unhappy with the lack of communication, and I had to do a lot of chasing to expedite progress.

I am a qualified electrician and chose EON for their interest free term on my £15,000 investment. Quote allows for "GivEnergy Hybrid Gen3 inv. with 9.5kWh battery - they have fitted a Gen 1 unit, confirmed by GivEnergy. Delay to install due to a ‘bespoke’ scaffold quote required - this was a flower bed. Work took longer than expected due to incorrect scaffold erection - this resulted in delays to install the panels in total work was completed over 8 working day’s not the one that is within the quote. When engineers left after the first visit the earth cable had not been installed and connected between the inverter and battery pack. Earthing is to provide protection. When engineers left after the first visit the main earth had been cut to facilitate earthing of the gen meter consumer unit. Strands of the earth had been cut back to allow it to be terminated. On the second visit the engineer replaced it with a standard earth block at my request. It is not acceptable to cut strands of a cable back to fit the terminal block. Handover documentation - is poor to say the least. I'm running out of space - an unskilled person would not be aware of the danger and incompetence of EON and their installers. A personal and a professional opinion would be to steer clear.

I agree with all the other reviews saying avoid this company and wish I’d seen this site before I ordered. I ordered the panels in May 2022. I paid in full in June 2022. After the survey in July it was radio silence despite constant chasing. In November they told me they had to change the design , which I accepted. Then they told me I needed an isolator fitted. They missed two appointments before eventually fitting it in january 2023. Their project management is so bad that they dont schedule things in advance so it was only after the isolator that they would schedule the installation. I was given a date of end April 2023. 4 days before it was due they cancelled because they’d forgotten to arrange scaffolding! After another cancellation they eventually fitted end of August - 15 months after I ordered! However, I’m still waiting for them to remove their scaffolding, despite chasing, and still waiting for confirmation of what rate they will pay me for export to the grid. Apparently there are more forms to be done , no idea why they aren’t done in advance , but completely typical of the incompetence and inefficiency of Eon Solar. Avoid at all costs. I’ve also been promised compensation on several occasions but still waiting …..

Avoid - shambles
Contacted June 22 Completed agreement and signed contract July 22 Survey completed Sept 22, then nothing for few weeks, even after calling/emailing multiple times. Received email in Dec 22, informing of delays and offering £50 in voucher. Chased for voucher and install date in Feb 23 - no response Received email in Mar 23 informing in changes to battery, and to sign updated contract Received call today to say survey team have said they cannot install. Only took almost a year for them to tell me they will not install - make your own mind up about why!!! Also, never did see those vouchers that were promised. I would Avoid this company at all costs.
