I ordered my solar panels with Eon solar back in August 2022 with a fitting date of end of September beginning of October. In between August/September I should have had a isolator switch fitted all organised by eon September I received a phone call to say that due to coming out of covid there’s a shortage of batteries my fitting date got moved back to end of October/November. I then received a phone call in October saying that there is still a shortage but Eon have a shipment coming into the country in a couple of days and my name is on one of the batteries but fitting date moved back again to December. I then received a phone call in December saying still a supply issue, I explain to the call handler the above conversation but all he could do was apologise. I explained to the gentleman that I still hadn’t had my isolate switch fitted with him saying that I had. After going back and forth the only way to get him to believe me was to take a picture of my fuse box and email it to him. Once he believed me he then said I had to contact Eon next to get them to fit the switch. I then received a phone call from a person literally straight after the call apologising, I asked him if he was a manager which he said no and my battery had been stolen at the port. it turns out he was a manager. After 2 hours on phone told they don’t have anyone who can fit panels in my area, so no fitting date and £59 compensation. The company is awful

Hello Thank you for your review. I’m sorry to hear we haven’t met your expectations on your Solar journey with E.ON.

Once we have everything we need for your installation we’ll be in touch with you. We’re operating on a first come, first served basis and prioritising customers that have been waiting the longest first. Although costs for solar have risen recently, your original quote will still be valid, and you don’t need to do anything else. Thanks Sally
How can this be a Trusted Trader?
I paid a £2.6k deposit for solar panels in April 2022. Nothing has been installed and my chaser emails are regularly ignored. The only update I have recieved is that they cannot source an installer in the area. Given its been 10 months I find that hard to believe and I suspect its more likely they cannot find an installer at a cost they want to pay...

Order completed on 22nd March 2022, this included submitting photographs of all aspects of the house. I needed to chase by telephone and by email until August 2022 when I received communication that that they were waiting on components. 30th November I received notification of the install date, 4th Jan 2023. 4th Jan 2023, the scaffolding contractor and the installation contractor arrived. The scaffolding contractor determined they did not sufficient access on the side elevation. Scaffolding was erected on the front elevation and panels installed. The battery was installed but the inverters were not commissioned. There was a lot of phone calls between the scaffolder and installation team and EON. Net result, EON will be in touch. Spoke with customer service the same day, the guidance being the hedge will need to be removed, which given it is a mature hedgerow was unacceptable. Also EON knew about the hedge placement when the order was placed. I then rang customer service every other day, it had been suggested that a cherry picker might be used. Nobody was taking ownership of the issue. 3rd Feb 2023 EON contacted me, after constant chasing on my part. It was agreed that the scaffolder needed 1m clearance from the gable end. This was achievable. 11th Feb confirmed work hedge would be trimmed on 20th Feb, requested install date. 21st Feb, been hanging on the phone 3 hours, emailed twice and no response. Appalling customer service, no escalation process, terrible call centre.

The Journey with EoN solar has been one of the worst experiences I have ever had with a large international company. They have failed to meet the timescales promised. They have failed to turn up on the agreed dates. The information they supply on the battery is misleading and fits the definition of mis-selling. The customer support is awful 30 mins to an hour on hold. You can never speak to the person dealing with your complaint. The person never seldom rings back. The complaints have been outstanding for months with no progress. Promises to escalate never materialize. A truly awful company which should be ashamed to be associated with them.

More of a marathon than a journey.
Despite being quoted 20 weeks for completion of the installation of solar panels In May 2022 I’m still waiting for a date for the work to START despite many phone calls and e-mails.

Absolute nightmare

I ordered my installation in February but there were constant delays such as cant fit scaffolding. Then my order was cancelled without notice while I was on holiday and my deposit refunded. After a number of e mails and calls I got a new install and I paid again. Further delays about scaffolding and a visit by installers who had the wrong roof fittings. Eventually installed on 9 August but I have no warranty documents or instructions, one panel was scratched when the scaffold came down after a month. I cant use the Eon home app because they have not given me details to sign on. I raised all my complaints by recorded delivery letter and e mail. No response by the Solar installation team but the retail side did get my SEG set up. No final resolution letter as promised. Do not use Eon to install solar, I wish I had gone locally even if it cost a bit more

Installation of 14 PV Solar Panels on South facing roof 5.5 Kw and battery "Givenergy" units of 5.5K. Full survey carried out by EON. Professional personnel throughout the installation- scaffolding team from wales excellent, electricians experienced and they instructed myself in operation of modules and controlling app. System worked first time and electric bills climbed down as June sun came along. Would trust EON staff completely and full backup for insurance, warranty and connection to the grid plus SEG forms all done for me. Thanks to all the EON electricians and staff at EON Solar for prompt service.

We had the following solar system installed... - 10 x 390 W panels giving a system size of 3.9 kW, to be fitted on Roof 1. - 8.2 kWh battery storage. We are very happy with the installation. The team that installed the system were very friendly and helpful. They did an excellent, professional job and tidied up afterward. My only issue is that E.on's after sale service could be better. I have contacted them with a few queries and it either takes ages to get a reply or no reply at all. One issue, in particular, is setting up our SEG account. I have sent numerous emails on the subject but still haven't had a reply. Pretty poor considering eight weeks have gone by and we are not being paid for the electricity we export to the grid.

8 Months and still no sign of an install date for Solar

Accepted the quote from E.ON in May for Solar panels to be installed, still no installation date. It has now been 8 months and at the time i was told a lead time of 3 months for solar and 6 months for solar and batteries (i went for just solar due to this increased lead time!) Apparently they no longer have any installers in my area so I now have an indefinite wait until they do it seems. Were supposed to be onboarding some in December but that didn't appear to happen Poor communication, I only ever get information when I chase them, or I would not hear anything around progress. Raised an official complaint - that was ignored. After chasing they acknowledged the complain about a month later and promised weekly updates - that didn't happen! As solar demand and therefore prices have increased significantly, even with the increased price E.ON offer to accommodate interest, it would now cost me a lot more for the same installation if I was to go elsewhere, so am stuck waiting for E.ON. I think E.ON are aware of this so I am low priority and they are more interested in new business with higher costs and increased profits. Been a nightmare so far and no end in sight, would have gone with another installer if i'd known it would be this bad and would avoid in future.
