At first extra energy were a good company. Reasonable prices. However, when I moved I discovered something different.... Despite having CREDIT on my meter, they've tried to bill me for over £600! They said it was from a previous address, then kept getting the addresses and account numbers mixed up. I've made several complaints and demanded to know where the supposed "£600 bill" came from. And also queried why they couldn't refund me the £50 credit on my account when I left. No straight answers! Scottish Power will be taking over from extra energy and I'm glad of that.

From my experience I would not recommend anyone to use Extra Energy. There are many reviews online including on Which and MoneySavingExpert that would reflect my feelings. Having moved into a house supplied by Extra Energy I had no alternative but to be supplied by them for the few weeks it took me to set up an account with another supplier. They supplied me for 3 weeks for Gas ONLY and I was shocked to receive an extortionate bill for nearly £80 (I'm in a small 2 bed house). Communication with their Customer Service to appeal this proved futile. Their customer service staff repeating set scripts like soulless robots. Their argument being that I could have had a cheaper tariff if I had taken out a fixed price tariff contract, thus signing up for a year (sure!!). But because I was forced into being supplied by them until I could get a different supplier set up, of course I didn't want a 1 year contract... therefore they charged me an expensive tariff because I was trapped in to using them for those 3 weeks. Avoid! They do not care about their customers, just their money.

ExtraEnergy owe me over £700, they reject my emails because my orginal email no longer exists, they advise me to change on their system, but my account is closed so I cant, even they cant, so now I am having to take them to court - if any one from ExtraEnergy can be bothered to pick up the phone the account number 003150

DO NOT USE this company! they are very quick to take on your business but then once you become a customer our experience is that they will put EVERY obstacle in your path when it comes to replying to queries and general account handling. One day they will speak to you on the phone and the next time insist that they can't due to the dreaded Data Protection rules which makes any communication less enjoyable than pulling your own teeth out. if you have a lifetime to deal with such matters, enjoy being treated with complete contempt and love a battle then this is the firm for you I don't and would not go anywhere near them!

Fortunately, I have now left this awful, horrible, so-called very devious and nasty utility provider and have, thank the Lord, moved my electricity to Octopus Energy, who are outstanding in comparison to Extra Energy!!! Extra Energy have absolutely dreadful 'customers services'!?! are non existent! Be warned, their sales contracts/sign up department will constantly lie to you and sign you up on as long tied in contract as possible, based completely on non-factual standing unit charges and horrendous usage rates! Once you are in their evil grips, they will MASSIVELY HIKE UP YOUR MONTHLY PRICES, WITHOUT YOU KNOWING & ON THE SLY, TO RIDICULOUS RANDOM NON SENSICALE FIGURES AND FREELY PULL OUT YOUR BANK ACCOUNTS VIA DIRECT DEBIT WHATEVER THEY SO CHOOSE, AGAIN, WITHOUT ANY PRIOR WARNING, NOTIFICATION OR ANY FORM OF CONTACT!!! FACT!!! DO NOT EVER USE EXTRA ENERGY - EVER!!!! THEY RE ALSO BEING HEAVILY INVESTIGATED BY OFGEM AND THE OMBUDSMAN FOR THEIR VERY BAD AND TOTALLY WRONGFUL BUSINESS PRACTICES!!! THAT SHOULD RING VERY LOUND WARNING BELLS TO ANYONE EVEN CONTEMPLATING SWITCHING TO THEM!!! ALSO, DO NOT BELEIVE ALL THESE '5 STAR' JUST SWTICHING REVIEWS WHICH ARE BEING COAXED TO NEW SING-UP CUSTOMERS BY EXTRA ENERGY SALES DEPT. AND LEFT ON TRUSTPILOT IN FACT, TRUSTPILOT ARE JUST AS BAD AS EXTRA ENERGY BY ALLOWING THESE TO BE LEFT ON THEIR SITE!!! PLEASE -JUST AVOID BOTH!!!

during 18 months supply extra energy charge more to each direct debit.they now owe me in excess of 3400 AS I CLOSED MY ACCOUNT AT BEGINNIG OF OCT.I have spent 40 mins on telephone being passed to the wrong dept. It is almost impossible to get reasonably contact with them and they are deliberately slow to sort out meter readings. I will be forced to resort to legal action to recover my money I would not recommend them at all

having apparently been on a no contract contract since 2014 without my knowledge hey have now presented me with a bill for just shy of £3000. apparently they did not know who the occupiers were and took no action to find out, I have been under the assumption in was with British Gas as I have been paying them. Threatened to cut off my gas on the 2nd October and turned up at one of my offices to apparently do so today with an alleged Warrant which he was unable to produce. yes I am a law firm and when I spoke to the guy from one of my other offices and told him I would be over in 15 minutes to discuss this face to face he legged it. next step ombudsman and possibly legal action for extortion. Really worried my receptionist such disgraceful behaviour needs teaching a lesson

Wish I had never changed to this Company, biggest rip off I have ever encountered.

The worst customer service ever. I had to increase my direct debit just to get a refund of £161.41 which they owe ME. . And it's July so not using much. Was told 3 July that refund would be sent, but after checking on 6th and calling them was told it takes 21 days to process. What rubbish. They are earning interest that's why they don't want to refund!!! In April when I owed Extra Energy £12.16 they insisted I paid this by debit card before they would keep my payments for dual fuel at £43.00. My contract is up in October and I will be leaving, and I advise anyone and everyone not to join them. They put their prices up one month after I signed.

extraenergy is a company that's offer champagne,but delivers lemonade, offering call back, I'm still waiting. They make deald they can not uphold,when asked about there deals the are very evasive,though some of the staff do try, it seems there complaints department pull the strings. (shame as some staff seem genuine)

Worst energy supplier I have ever had to deal with. I have a number of rented properties and extra energy sounded like a good company to work with to begin with, I was very wrong. They would send bills on accounts that had been closed, put supply on incorrect tariffs and send estimated bills when accurate readings were sent. Was all very frustrating, especially when you wanted to leave. Although some staff were friendly and seemed helpful the bills were a mess and you would get told different things by different staff which would confuse things. I would never recommend extra energy and urge to stay away.

I joined extra energy late in 2014 as my energy bills were quite high. I did get a good deal with them at first, bills were much lower. However I only recently received an email (early 2017) saying I owed them over £400. I rang to discuss clearing the debt and they said they wanted nearly £50 a month off me because they wanted it paid back within a year. I told them I could not afford this as I'm on a low income. I e-mailed them a budget sheet showing them the amounts I could and could not afford and made them a monthly payment offer. However they did not accept this. They continued to pursue me for the debt by affecting my credit report and getting debt companies to contact me. I made a complaint to customer services and they are messing around with getting back to me. When I call I am passed from one department to another and my issue is never resolved. I know they have received the complaint and the budget sheet as they sent me an email to confirm that they had received them. Yet they deny this when I speak to them on the phone. I will be going back to citizens advice soon if my situation is not resolved and may have to go as far as the ombudsmen. May I also stipulate that the bill they sent me was for £489, yet when the debt collection called me they were only asking for £210. It's likely that I don't owe as much money as they say I do. I also question why they are billing me after 2 years of me not having an account with them. It is suspicious. I advise anyone NOT to go near extra energy. What they are doing is actually against the law but they don't care as long as they can try and terrify people into getting money!

I left Extra energy 6 weeks ago and am unable to get a final bill despite paying by direct debit and now owed money by them - they blame Iresa who I moved to and Iresa says its Extra energys fault as there MOP's team hasn't sent them the meter point information required which is required when sending the final reading Iresa has escalated the problem and Extra energy has highlighted the problem and says it may take up to 12 weeks to resolve, it appears to me someone is playing games or being spiteful, I for one will never ever return to Extra energy, the last bill I got from them was up till the 22nd November 2016 despite paying by direct debit every month, I have worked out what I owe them and I am due a refund of over £80. I think it is fair to say there customer services are non-existant and any savings made with them are not worth the aggravation which follows

Simply I would not recommend this company and I will certainly not be using again. - Left the company after they could not switch my account on moving in to 'consumer' account from a business one. - Received first bill Months after leaving them with a standing charge of £79 (from a £22 bill) - Still waiting for a charge for electric bill (requested told 'the bill will come in the post') - I was told I could not complain given there is not a 'name' on the account. This suggests an appalling IT system given this should be possible with only the account number. (Inconsistent customer service ) - Customer service told me that they were 'Online only' even though I do not have an online account, then they told me that they do send bills

terrible company, staff put you on hold, cut you off. Awful!

Please dont go there!!!Its the worst company I have ever known. Could take my gas over for 6 months, than kept charging me after I left 6 months on!!!!Lots of money on phone calls, not trained staff, they dont know what they are doing. They sent a dept collector on me,for a bill I paid 6 months before. PLease save yourself money and time!!!!!Dont have them, other companies are cheap aswell but much better.!!!

Avoid extraenergy at all cost, because any association with them will cost you dearly. Dishonest billing, ignoring customer reads for their own estimates. Refuses to wave leaving fees even though contrcat period ended. I wouldnt trust this shower as far as i can spit a rat. STAY AWAY FROM THEM
