Some users say it’s a genuine outsourced service (First Source) handling smart meters for Eon, with confirmation from official Eon sources.

I received an email claiming to be from Eon, saying there was an issue with my smart meter and it needed a replacement. Instead of calling the number in the email, I rang Eon directly and they told me everything's fine with my meter and that the number I was given isn’t theirs at all. Pretty sure it was a scam attempt.

I called Eon to make sure the number wasn’t linked to them and ended up getting a call back just like a health check or something. Bit odd if you ask me!

I just called 0808 501 5200, thinking it was E-On, but they said it’s not one of their real phone lines. Also, watch out for emails from this address [email protected] - seems dodgy and like a scam, so be careful!

I got a call from 03458623405 and found out it’s this company First Source. Eon Next gave me this number since my smart meter wasn’t working properly. Apparently, First Source handles the smart meters stuff for them.

I keep getting emails saying my smart meter is about to stop working. I called E.ON Next using their contact number but the lady I spoke to wasn’t fully clued up on smart meters, said she hadn’t had the training yet. She thought it might be one of theirs but also warned it could be a scam. Still not sure what to believe, so I’m going to be careful and avoid calling any numbers from the emails.

I got a bit wary so I rang E-On using another number, and they assured me it was definitely their line.

Had another email come through recently and I got in touch with Eon to check it out. They told me it’s definitely a scam and said not to click on any links or phone any of the numbers in the message.

I got an email supposedly from Eon Next warning me about my smart meter. But the sender's address was different from the official Eon Next emails I usually get, which always come from '[email protected]'. The message started off quite aggressively, saying something like ‘Your smart meter will stop working shortly, so we must replace it.’ Pretty obvious to me that it’s a phishing attempt.

I got an email from [email protected]'. The message kicked off with a pretty threatening line: 'Your smart meter will stop working shortly, so we need to replace it.' Pretty sure that was a dodgy phishing attempt.

I just found out that 0845 862 3405 belongs to EON’s Smart meter support, but it’s handled by an outside company. What annoyed me was they never mention it’s a premium number, and now I’ve got a charge of more than £10 on my phone bill for ringing them. Proper cheeky if you ask me!

I recently received a rather peculiar email purportedly from E-ON ENERGY, which is quite odd considering I'm actually a customer of E-ON NEXT. The message warned that my Smart meter would cease functioning unless I arranged for an updated installation, directing me to phone 03458623405 to set up a visit. Another thing that raised my suspicions was the logo in the corner of the email-there was a disc with the letters "EE" in it, whereas E-ON NEXT typically has "EN" displayed. Feeling quite uneasy, I decided to ring E-ON NEXT directly at 08085015200, the number I'm familiar with. They confirmed that they had not sent any such correspondence regarding my Smart meter and advised me to disregard the email altogether. Quite suspicious, indeed!

I called up about switching out my meter and got a message from E.ON Energy. They emailed me back to confirm the appointment, and it had my account details and what I still owed, so I knew it was the real deal.

I got an email that looked super legit, saying my Smart Meters would break soon and had to be swapped out. Something felt off though, the message style was just like the scam texts I've seen before. I rang up Eon just to check, and they told me straight away it wasn’t from them at all - so definitely a scam!

Got an email claiming to be from E:on Energy, not E:on Next. It looked quite legit and well put together. But when I checked my E:on Next account, there was no sign of any message like that. Not sure what they are after with this info, but it’s the second time in a month I’ve had one of these dodgy messages.

Got a message that ended up in my junk folder. It said it was from E-on and that my smart meters had to be replaced. They were also offering £30 as some sort of compensation for the hassle.

I reckon this might be one of those smart meter scams, looks dodgy to me.

So, I got an email from Eon Next asking me to ring this number to get a Smart meter moved. Turns out, Firstsource is the company they use for putting in, swapping out, or relocating these meters. I've put my experience down as just okay because the email I got wasn’t from a person but their AI auto-reply system.

E.On Next called me yesturday, but I have no contracts with them. Pretty sure it was just one of those spam calls trying to sell stuff. Annoying!

I got a call from this number but they just hung up straight away. Tried ringing back and it told me the number doesn’t exist or something like that. Pretty weird.

I can verify that the installation crew for the smart metre is genuinely from E-on Next, as I’ve checked with them directly.

I suspect there's a connection to the number 02922229992, which appears to be associated with eonext, and they've charged me £30 for checking my smart meter.
