isupply, now supply both gas and electricity to give you a dual fuel deal.

About new energy suppliers in general

It’s very complex to set up an energy supply business. Invariably, there’s quite a learning curve involved. When new suppliers appear among the cheapest on comparison sites, they tend to attract a lot of new business. This can cause a lot of problems if they don’t have enough employees in place to handle the various departments.

Would I switch to isupply?

The fact that this supplier is not getting great reviews would put me off.

Although you may be tempted to switch to the cheapest, please be careful.

I would most likely skip through the cheapest in most cases and, switch to one of the following suppliers cheapest online tariffs.

Isupply Crooks and Thieves

Having followed their procedures online of moving procedures, spoken to a customer adviser who said they will be reimbursing me over £200 of overpayments within 30 days, it did not materialise. My online account had my balance as being owed the same amount. I called them again (if i did not call they would have been happy to forget) and the adviser said there was an error on their part and the payment should reach me within 2 weeks. Following that i called again - this time the person i spoke to said according to their records they do not owe me anything and in fact i owe them! I checked my online account again and to my amazement they had changed my balance and made it look like i owed them money!!!!I told them of my previous conversations and they said i was mis-advised and there was no record of this.I will be contacting the police ombudsman and taking legal action. This company should be stopped from and people arrested.

Don't use them their pathetic and they are difficult to contact.Firstly they did not advise previous provider as promised.Then they set up 2 direct debits,or should I say they sen t 2 different e-mails to say they had.When I cancelled direct debit as I was unsure if 2 were set up they charged 10 pounds when it was really their fault.I made 2 written complaints neither of which was handled correctly and whilst I am still with them I will be moving provider at the earliest opportunity.Dont use them.You have been warned.

Simply the Worst

They don't even deserve 1 star but you have to give them that! Had difficulty when I opened the account . They found it very difficult to accept the opening meter readings as they were 'unverified' OK whilst in contract but leaving them has and is horrendous.Now nearly 6 months on after using the wrong readings they still have not got it right. call centre staff always polite and sympathetic but can't do anything on numerous occasions promised callbacks from supervisors only once has this happened. don't even think about using them.

IsupplyEnergy Provides False Information to Credit Reference Agency - Beware!

I was a customer of this company for 3 years. That was 2 years ago. However, I was surprised to discover on my credit file that the company had recently suddenly opened an account in my name and claimed that I was suddenly missing payments to their company within the last 3 months of this year. This was despite the fact that I had closed my account with them over 2 years ago and fully settled the final bill leaving it with a zero balance. I have had no contact or association with this company since that time so I was flabbergasted to discover that I was suddenly now missing payments to their company in 2017 despite not even being a customer of theirs and hadn't been for over 2 years! The cheek! As a result of this company's actions, my excellent credit score plummeted to a negative and adverse number.I subsequently contacted the credit reference agency and successfully managed to have this false information removed after 2 weeks thus my credit file was restored to its original state. I also contacted Isupply Energy by phone, email and letter to their Head Office for an explanation. That was never forthcoming. Avoid this company at all costs if you don't want them to unjustifiably hamper your credit file down the line years after being one of their customers. Also, do check your credit files with Experian, Equifax and CallCredit if you are a former customer of Isupply Energy as who knows who else they have done this to??!!

by Alex Martin on isupply reviews

It's been months now I've been trying to get nearly £200 refunded to me and they are throwing every possible obstacle in my path, and all along they have acknowledged that they owe me the money..!! DON'T USE ISUPPLYENERGY. Use a company who won't treat you like dirt.

Poor customer service isupply

Poor customer service, waiting for final bills for both gas and electricity but got changed late payment as my account that is showing in credit hasn't managed to be confirmed and have been told it could take up to a week to receive the amended final bill including the unreasonable charges but if I haven't paid before the the cut off date that is next week I will get charged again!How can I get charged for a late payment if I haven't received the bill or had a chance to pay????Shocking

Avoid, avoid,avoid at all costs. The worst customer service ever by a long long way.

by Gary on isupply reviews

I urge people not to deal with this TIN POT outfit.They do not know what they are doing.They will mess your duel fuel accounts up.I have ended up at the onbudsman because of their inability to get a simple switch sorted.

Review of I-Supply

Awful experience, terrible communication. STRONGLY AVOID!I moved address, sent them a meter reading the day after I left via email, and did not hear anything.I did not hear anything else and they put a default on my credit file.Stay with your existing supplier or if you move then ensure they are a well known and reputable company.

by Harry K on isupply reviews

Seriously, steer well clear of this energy supplier - they are abysmal. I've had problems with them from start to finish, with the issuing of incorrect bills, terrible customer service, not being able to close my account 2 months and counting after having switched suppliers due to a fault on THEIR part with no attempt to resolve the issue. Join if you want to spend hours on the phone to them getting nowhere - it really shouldn't be this difficult dealing with your energy supplier. They are horrific - do yourself a favour and pick ANYONE else in the market.

by susanne on isupply reviews

they maybe the cheapest but what they forget to tell you is their customer service is non existent. I'm buggered for a year now as they can't change a direct debit date, thats a first for me as ever company i know can change the date. as soon as i can i will be leaving them, they just want your money

by Zelie Lewis on isupply reviews
Worst energy company ever

Really the worst energy company I have ever dealt with... completely incompetent, wrong information throughout, have collected money a month ago for fuel they haven't even provided and haven't refunded me. Hours of calls. Just don't ever make the mistake of using them.

Groundhog Day.

I'm lost for words to describe how bad this company is. I left British gas in 1st Jan 17 but iSupply claim that they don't have the account. I can't contact them. I can't submit a complaint.It's like Groundhog day.BG say a company called "Contract Natural Gas" are now supplying me - I've never heard of them. Its like banging my head against a brick wall.

Shocking plesse avoid

I applied to join I supply but cancelled within the 2 week cooling off period. However they have then proceeded to take a payment. This was over 3 weeks ago now and 2 phone calls and 1 email later i still haven't received my money back. In all honesty the money probably gone but if i can save 1 person the aggro ive had by reading this ill be happy. Avoid these like the plague.

A Joke

// ZERO STARS ////Moved on Jan 6th- provided final readings that day.Called to chase final bill repeatedly for 3 months, 'a stop on the account...system issue' blah blah blah. since then I have it, I am owed a few pounds. Soooo Isupply take £26 as a DD? then send me another bill for £12 - now getting overdue notices and my account shows £45!!Getting on for 4 months and well into double figures of complaining phone calls and emails and getting nowhere.NObody there has any clue what is going on - so much time wasted and so fed up of it. Changed energy suppliers at my new house 2 months ago, all sorted in a fortnight.A third of a year has passed and still can't get rid of isupply from my old house.AVOID!

by John on isupply reviews
Horrible administration

Isupply had the worse customer service experience so far.Their online portal is anachronistic, there is no email communication, no one answers calls when they do they assume the customer is at fault. I was presented with a bloated final bill after leaving and I still receive overdue messages even though I payed of the bills three months ago

by Jimjams on isupply reviews

NO STARSThis company are best avoided unless you want a load of AGGRO. I enrolled onto a community dual energy program with them last November. I had a small issue whereby I had had storage heaters and my electric had been on economy 7 three and a half years ago and I always have to explain this whenever I change energy supplier. I explained this to them prior to the program starting and they said it wouldn't be a problem and we will sort it out once the program has started.They have now gone back on their word and refuse to change me to a single electric tariff, which I estimate is costing me about £10 to £15 pounds per month. They say I can leave on payment of £60!! I feel stuck despite numerous phone calls and emails, which has now turned into a one way conversation as they have stopped replying to me. PLUS, I've reported them to OFGEM. Hopeless. So, if you want to save yourself lots of unnecessary AGGRAVATION best go somewhere else with your order. Plenty of other firms on the internet who will supply your energy as promised but sadly not this lot.

Inefficient and dreadful!

I soon realised during the cooling off period that isupply was a very poor provider, almost impossible to contact .When I did get through the people on the line were rude and unhelpful, would not admit that I had sent e mails or a letter cancelling the service.DO NOT use this awful company

by Peter on isupply reviews
Walt Disney company!

This is a terrible company, I signed up in March all on-line, then I discovered they charge you an upfront charge of your monthly payment (mine was £39 + £35 =£74.00) this is just an extra payment! it's not for energy. I tried to get in touch by phone but never get answer. email is impossible as I get informed to "phone". I found a number to phone, was greeted by a surprised voice who asked where did I get this number, I cancelled as I was just inside the cooling off period ( I was lucky) I asked if money would be taken out of my bank account and was assured "NO" guess what, it was but I had instructed my bank not to pay this company any funds and it was paid back in same day by my bank. Don't just take my account of this company read other reviews.

by james on isupply reviews

What a totally useless company customer service 0 out of ten 45 emails & 5 phone calls and still not sorted out . its only taken 4 months and still no gas .DO NOT CHANGE.

    When iSupply found I’d decided to leave they sent me a change of direct debit notice, putting the debit up by £5.
    Two days after my contract had terminated I cancelled the direct debit but they still continued to take money from my bank, even though I had left!
    It took them over 6 weeks to send my final bill, with still no refund of the amount I’d overpaid. To my horror they’d added a £10.50 fee for cancellation of the direct debit, something I’d done, not them.
    The saga continues . . . . .

    My contract finsished in early October and I have a credit owing to me of over £600. Two phone calls and great patience on my part but no signs of the money coming back. Surely this is a criminal offence??

    poor service, you are passed around from one department to another, may be cheap but very poor customer service. If you want to waste your time on the phone to this guys, then this is the service is for you. Staff are not trained and do not care. VERY POOR CUSTOMER SERVICE.

    After watching Martin Lewis pushing people to find a better deal I decided to swap to iSupplyEnergy. He said it wouldn’t take long and is easy to do. That was back in December and it is now June and they still haven’t sorted my account. Electricity was swapped over straight away but I’m still having problems with my gas.

    Firstly the change over never happened on the day it was supposed to. They still decided to take money from my account even though I was still getting my gas from my original supplier. I did get a refund.

    In March they finally started supplying my gas. Late April I was waiting to see how much money came out of my account for the gas I was using and to my surprise no money left my account. I logged on to my online account only to find my direct debit details weren’t there. I rang them up to sort this out.

    Still watching my account another month passed and still no money came out of my account. I logged onto my online account to see the message “This contract does not require a Direct Debit payment.” So again my direct debit details have vanished….again!!!

    I sent them a message on their online system a few days ago asking if they have decided to give me the gas for free considering I am trying to pay but they just don’t seem to want to take my money. It is now 2nd June and they haven’t got back to me yet.

    So basically this company first took money from me without supplying my gas and now that they are supplying my gas they aren’t taking my money.

    If anyone out there is thinking about changing their energy supplier to iSupplyEnergy I would save yourself a lot of wasted time and energy and DON’T DO IT!!!!!! It has been 6 months for me and it still isn’t sorted.


    p.s. Thanks a lot Martin Lewis

    Trying to get through to customer service seems impossible after getting past auto your left hanging for god knows how long as I’ve yet to get an answer seriously thinking of changing supply but worried as all reviews I’ve read tell me I could loose a lot of money from them if your thinking of switching to them I wouldn’t I have and am now regretting it
