This is by far the worst company to deal with bar none! They don't care and will manipulate any situation their customers are the last thing on their list of priorities. Every review is negative why isn't someone doing something about them!

The most useless customer services ever. Will blatantly lie to get you off the phone. Will attempt to avoid compliance with General Standards of service. They left a house with a small child first with no gas and then no electric through their own fault and failed to fix it. 5 engineers missed appointments even when confirmed multiple times

After a year and a half of trying to resolve a bill discrepancy, I finally gave in to Npower and paid an incorrect bill. I asked for the situation to be escalated, which they never did - They took the wrong meter reading for a different house and tried to charge me for nearly three times the amount we eventually settled on! How do you make such a colossal mistake like that? After approximately 30 calls (which I had to make to them) and generic, threatening letters in the post, I finally had to give in due to their incompetence. They are the worst, most revolting company I have ever had the displeasure to be involved with. I will never ever use them again and I cannot stress enough for anyone reading this, to take your custom elsewhere. I'm now using Spark who are fantastic all round.

Npower were my supplier at my last address and quoted me £120 per month for both my gas and electric supply. I paid the amount I was quoted but received no bill for twelve months due to their systems being down. Finally receiving a bill twelve months later I was devastated to realise that they had billed me an extra £1300 on top of what they had quoted me. With a high usage of gas and electricity due to a severely disabled daughter I knew I would struggle to meet payments,which I did. Last year I had to move from that home to another,I informed Npower of my change of address but heard nothing until one month ago when I received a court enforcement notice saying bailiffs where coming to my home for the total amount of £2900. I immediately rang and tried to resolve the matter but with no luck. They have ignored my calls to look into the late billing and have now said I have to pay their solicitors fees or face bailiffs coming to my home which I am petrified of because of my daughter. So I have agreed to pay whatever they want me to pay because I fear they will come to my door. All this was taken to court without my knowledge ,the case was heard without my knowledge and I have no court papers at all because the paperwork went to my old address. I have been hounded by phone calls and their solicitors and have been shown no help what so ever. I have had sleepless nights for four weeks and feel physically sick. I would never ever recommend this company to anyone and if I could give a minus star review I would. Absolute torture.

had a faulty meter for 18 months despite complaining repeatedly each mont nothing happened until the meter showed red which means it had ran itself out, they then said they could only offer me £75.oo despite me paying them £95.00 a month for months, they couldn't even organise someone to come and fit a meter on the day they said they were going to. I also had endless conversations with idiots who said one thing and did another on one occasion this conversation wasn't even recorded. when it was acknowledged they were wrong I was contacted by a member of the complaints team I agreed to close it simply because I was sick to death of dealing with them the following month they then charged me £95.00 again when it should have been £48.00 I have now left but trust me u will never deal with anyone as incompetent as n power how they are allowed to operate is beyond me

we contacted npower to see if they ran our Gas, they said no even though we were paying them for our electric. then we had three big guys show up during the middle of the day that decided to slap the meter on while i was on the phone with Npower. spoke to 3 different people who all had different things to say. the guys then left not connecting our gas and have left us in the house without gas til thursday. There are children in the house which they couldn't care less about! then after another hour on the phone they charged us £76 to get someone to come out and supply us gas.... will be taking this a lot further! my advice is DO NOT USE Npower!

Never again would I be with N=power been trying to switch to EDF each time you ring them they give you a different reason why they have objected I'm not going to let this go , Don't go with N-Power my advise

Horribile and Cheater company..They charge you double for same electric and gas..I was trying to leave "npower" but they are raising objections without any reason. When made complain, manager in customer service make ojbections on the fly..Like my application for rejected on 8th of March 2016, all previous bills paid. The latest bill recieved on 3rd April 2016. The manager said there was outstanding balance on 8th of March 2016. I asked, how would I know there was outstanding balance. Would I see my bill in dream or an agel will tell me? You should have issued final bill then and I would have left. I was due to leave on 27th of December 2015 and after 4 and half months I am still with npower paying double price as comapared to Extra Engery that I am moving to. "npower is a cheater and trying to keep customer with them with cheap tactics

as I new business I had a call from what they said was metre retention (there is no such thing) implying they were a government service saving business money on energy all lies I have since found out it was a broker and I am now tied into a higher tariff than npower would have given me I explained this to npower who could not care less and are holding me into the contract knowing the bad practice used and I am sure continue to use the broker awful avoid avoid avoid

Can't tell you how bad they are , incapable of getting the bill right, refunding me one minute saying I'm in debt the next. In the end their errors messed up my otherwise perfect credit rating and stopped the lease of a new car. They even gave me down as defaulting on my GAS bill when it's an oil fired property (no gas connection). Utterly incompetent, incapable of putting it right.

Initially decided to leave because one of their phone operators was giving me incorrect information and kept insisting I give them my credit card details. Ended up switching in mid-Jan. Npower decided to bill me for two subsequent months, and its only this week I have recevied my final bill which has been completely based on estimates. I kept calling them in the interim to hear they hadn't received any information from my energy supplier which is a complete fabrication since they get this from a 3rd party as part of the leaving process. Each time I contacted NPower they invented a new story and I still don't know when they will pay me back my outstanding amount. I made several complaints on their website but this doesn't do anything. You need to establish a complaint via the phone and make sure you get a complaint number. About 5 days later they texted me to say my complaint had now been resolved, even though it hadn't. I'm taking it all up with the Obmudsman but in the meantime I suggest looking elsewhere for your energy.

Appalling customer service. New property supplied by Npower. Changed to another supplier. Entire process completely cocked up by muppets who contradict the script they are given every time you ring them. Told my new supplier a pack of lies on the phone and then denied having the conversation. Still waiting for it to be resolved.......I suspect the Middle east may have a better chance of being resolved then my final bill!! Apparently I have to give a rating. Would like to give Npower a big fat zero stars!!!

Worst of the worst, cant even answer a simple query in 3 phone calls. Now left with no option but to wait till tomorrow. Last call agent dumped us and couldnt call again as time was finished. Terrible terrible service, would never join them.

Appalling Service, Woeful Billing, Complete incompetence

N Power = deceit, liars! They put me through 2 years of upping my bills from £52 per month to £94 per month! I found them out after my complaints and they have it on their records. I managed to get £180 credit back after they lied on the phone - one time they said one thing; another time they said something contradictory and they couldn't deny it! But the level of professional misconduct and lies they gave me was foul - and I would be very happy to see those liars go bust! Now with my current supplier - I am only paying £52 per month and still in credit! That was the second time I was with N Power - never again will I return to them! They were a company who first thought about themselves and their profits and fat pockets and lastly about their customers If they would think about their customers first and themselves further back, now they would not be in so much trouble! Worse to them - they have lost my respect and trust for life! I had to suffer more epileptic seizures fully because of their mistreatment! They didn't care anything - only their pockets and pay packets! Good riddance to bad rubbish! Of course - they haven't got the guts to apologise and earn respect back, have they?

Moved into a new home recently and they were the suppliers. Called them to say I was not staying with them but moving to another company. I though all was okay and the change went ahead without a glitch but them I got a bill off them for the 3 weeks they supplied me. I could have heated Buckingham Palace for the amount they want and to add insult even though it says I have 3 weeks to pay it they have not stopped calling to demand payment. Told them to "F" off today as enough is enough. One bill says one amount, my online account (I never set one up but seem to have one) says another then I get another bill for another totally different amount and still the calls are coming in hourly from their collections department. After telling them I would report them for harassment if they carried on all they would say was I still hadn't paid them...that would be the 3 confusing over priced bills I received in the last 5 days...all with 3 weeks to pay written all over them!! May simply just avoid all further contact and refuse to pay anything, what can they do?...SOD ALL is the answer...not scared of the computer generated so called debt collection letters from companies that don't exist as they are part of their company. And if they do sell it on then tough luck on the idiot that buys it, they pay £1 for it and of you do stupidly have contact with them all you legally owe them is the £1 they paid..

Avoid at all costs! They may look cheaper but the amount of time & effort you will lose sorting out their problems is not worth it. Worst company I have ever had the misfortune to deal with. Appalling level of customer service. Wanted one online account & to pay by DD & they failed miserably. I had to refer the matter to the Ombudsman which needless to say I won. The last correspondence I received was a bullying court letter stating that despite attempts to contact me I had not got back to them. This despite the numerous calls & emails to them just shows the level of incompetence at which they operate. Even after receiving letters from them confirming my complaints were being dealt with and they could not tell me what they were charging me for. Staff are useless. The management worst. Scored 1 star as I had to put something otherwise it would be nil. They should be closed down.

Stay away from them , they will do anything to take money from you ..
