Needed new gas meter and new smart meter. Came out and did it all very quickly. Had Jason Grey.

The smart meter was defective from day one and changed twice. After three months we kept getting erroneous readings and at one point e-on demanded £500 for power used , later reduced to £206. It’s a terrible company who never ring back or do what they say they will ; absolutely hopeless…..

Utterly disgusting service from eon energy, I kept asking for my direct debit to be reduced and then the following month it went back uo again.
I left eon overb6 weeks ago and they owed me almost £400z of which I am still waiting for a refund, customer service just give excuses why I have not had my refund yet and fob me off.
I have given a 1 star review because that is the lowest score I can give.
Do yourself a favour and keep away from the big suppliers and go with the smaller companies who give a much better service.

Smart Meter installation.
Was fed up being bombarded by comms. from EON trying to get me to have a Smart Meter fitted, to the point where I felt I was being harassed. Eventually succumbed.
Firstly, can't fault the quality of the work by a young, friendly technician.
Was booked for an AM appointment. Had several text updates during the morning, bringing timings forwards and backwards.
Finally got a phone call from E.ON to say they were having 'issues', and that the appointment time had been extended up to 4pm, which I agreed to, as was unable to commit to another date
The upside was, I was credited with £40 to my account, as the original slot booked and agreed wasn't met.

Had Dave from E-on round today to change to newer smart meters, honestly couldn’t fault anything. Very efficient and proficient at his job. Lovely fella, shame all workmen are that polite.

I asked E.On next to install a EV charger. Mr. Wayne cane and did the job perfectly. Really happy with his installation

I spoke to Brandon who could not hear me very well which was frustrating as was discussing an important issue with payments, neither of our faults-he called me straight back & spent a good deal of time going through different options & suggestions.
He was extremely professional, understanding, courteous & provided me (after referring several times) with a very helpful result.
This guy is an asset to your company, so very helpful, i am still astonished actually, felt like an actual person rather than a number which is how i normally feel!
Very very high level of service, please reward him!!
Thank you Brandon!

A few days ago I became concerned perhaps Eon were not logging in to my smart meter to update my usage. I contacted them via email and within a day received a reply from Jerry followed up by Christabel Eon help desk. I was assured that ALL was in order in every aspect of my smart meter. This was a gift to me of great comfort. I have been with Eon Next for over 20 years and at times I need advice regarding my power supply by them and always receive the immediate help I need in every way. ALL the staff there are experts in every aspect and my gratitude to them is eternal. Bless and thank you ALL and I truly mean this Robert

I'm a customer so I know the way they treat there customers, don't trust eon energy they offer you a contract so you pay direct debit then up monthly prices on a fixed 16month contract, you have no say they will just keep on overcharging you and threaten you £100 to cancel the contract which they offered me btw they will tell you to contact national helpline to spread out the cost. NEVER USE EON ENERGY trust me they are all money grabbing .... ! go elsewhere!! Octopus energy are much better. Unprofessional service through out my 5 years

“I switched to E.ON Next using a friend’s referral link and received their official welcome email confirming I would get a £50 voucher after the cooling‑off period. That period has long passed, and despite providing all requested details multiple times, I still haven’t received the voucher. Each time I contact support, I’m told they will ‘look into it,’ but nothing happens. Very disappointing experience for a simple referral reward that was clearly promised.”

EON have randomly assigned me a budget without consulting me. Given that they forced me to take a direct debit, and that there has never been a problem with payment, I find this offensive. They usually take more money from me than required, so my account is in credit. They also forced me to take a smart meter which shouts at me every week for exceeding the budget. I guess they expect me to switch everything off and freeze to death.

WE STILL HAVE NO ELECTRICITY. our small business has been without power for two weeks. Waiting on a meter fitted and still waiting for a call for an appointment, eon are single handedly destroying a small business and do not care.

I just get we are 'escalating this' and your 'complaint has been received. I am now contacting my locla MP and the media about this as im not sure they can keep on doing this for much longer to hard working small business owners.

I’ve just used the WhatsApp service and can I just say how easy it was. Rather than waiting on the phone I was able to get the query sorted easily by messaging. Thanks.

Ah Eon.. Like a bad insurance company, lures people with competitive tariffs, then takes the rug from underneath them when renewal comes.
From Forums, many have been leaving on renewal. The Next Drive tariff before September/October 2025 was mildly competitive compared to Octopus. The solar export a touch better too. The bad part was having to put up with the odd way manage exports :- needing separate account, claiming back via a form and waiting. Whereas in Octopus it was all integrated and seamless under one account.
Now the Next drive tariff hours cut, and solar export rates slashed to near a third. (unless solar panels installed by Eon, but thats not most).
Has been a good year to a point. But now seemingly you are penalised if you have EV and Solar.
Unless Eon suddenly releases similarly competitive tariffs as last year in coming weeks, for me it will also be time to leave.

Same problem again! I have to leave a review again about EON with the repeated problem of another energy provider trying to switch my supply. I think I am on the 4th cycle of having to sort this out. So frustrating after EON said it wouldn’t happen again.

Valentino visited me today to rectify a problem with my Wallbox charger. He confirmed the problem and decided that it needed to be replaced during the replacement he noticed a wire internally on the faulty box had become disconnected. He reconnected the wire which solved the fault. He informed me of the repair. Refitted the original box full test carried out. Which included test on vehicle. Problem solved efficiently and quickly. I was kept informed throughout the repair. Thank you Valentino for a job well done

Had new smart meters finally fitted by Ian today. Having had about 5 other engineers out over the years I wasn’t convinced that a smart meter would work as in a village on outskirts of Harrogate as no other smart meters were able to connect. Well Ian had the goods today able to install the meters and showed me how to use and understand energy usage on the meter. Lovely man and very efficient. Rang 20 mins prior to arrival.

Where to start.... Several total nightmares all solved by moving to EON. First Octopus Energy take over from Shell and break my meter, replacing it with new meter after messing me about for 6 months but failing to note down the change of meter reading number eg 00000. So EDF got in to a dispute with them over the inaccurate meter reading number but wouldnt bill for gas unless I left them... So bye bye EDF... Within a week EDF are sending me a threatening first letter demanding I pay the gas bill they had refused to send me until then... EDF where doing okay until that point.... That letter proved they prefered drama over solving problems.... So I moved to Eon... Problem solved... just gone... no drama, no fuss... no problem.
Moved house, had to switch to Ovo to keep the council happy for a month, prepayment meter complicating things and leading to massive bills... Moved back to EON on 1st Jan 2026... Problem explained, fix planned for 27 Jan, 2 new smart meters on the way... Sorted... No problem, no drama... EON does it again...

EON takes the problems other companies cause and makes them go away.... No stress, No Hassle... No problem.

moving in a few days and tried to switch the new address to Octopus an Eon refused it,

so contacted Eon and they said a previous account was at the address, I made it abundantly clear this isn't me and I'm moving in on the 20th and have nothing to do with the previous customer,

their reply, GIVE US ALL YOUR PERSONAL DATA AND TENNANCY AGREEMENT

yeah, I'm not a customer of theirs (nor do I want to), nor am I willing to give them all my personal data, nor am I connected to the previous account in any way,

they're cowboys who don't care about customers rights or that I want nothing to do with them

DO NOT USE OR GIVE YOUR DATA TO THESE COMPANY!!!!!!!!!!

Please please please do not go with the energy company! They will charge you random charges and try with everything they have too add debt onto you for false accusations! They charged me over £20,000! Do not go with this company!
