the renewal contracts are based Not based on current usage as suggested in the terms -but on , in my case 1/3 of my annual usage even though it clearly states that it is. the contract does give you the opportunity to change this but again in brackets it says based on current annual usage. It is deliberately misleading I will not be renewing

I switched to this outfit after seeing an IKEA promotion recommending them - what a mistake. Their systems are not fit for purpose and constantly produce inconsistent and illogical billing estimates and debit order requirements. The most worrying part though is that on engaging with their staff to remedy the issues it has become apparent that the systems are far more competent than the staff - this company is a crash waiting to happen!

Worst company ever! Inadequate tech support, IT that is not fit for purpose and Customer Service is non-existent. Have an ongoing issue for nearly 2 years that they cannot get sorted, have had to refer them to the Ombudsman twice and still no one can be bothered to call me back and yet another escalation has to be raised where someone should contact me within 28 days! If I could rate them zero I would. Avoid, Avoid, Avoid!

2 years into a 3 year fixed contract. Other than sending occasional meter readings I haven't had to contact them. So far just what I need from an energy supplier...no hassle with everything just running in the background. What more could you ask for.

Really had enough of them!! My bill has been the same since August 2018 They dropped my debt by £100 when I complained in August since then they have been charging us £197 a month but debt hasn’t dropped. Spoke with them few weeks ago as I refuse to pay until they sort this out. I am going to ombudsman. My husband has cancer and is very ill. Do they care!!!! NO I can’t change suppliers as I don’t know what I owe!! DO NOT USE THIS COMPANY.

I had to ring to give my meter reading because I’ve been having problems getting logged into my account and the person I dealt with helped me to do it and was very patient as I’m not computer literate,he talked me through it.it was like having my own private tutoring me to learn how to use a computer and I’m very grateful for his help.thankyou to him.

I have dual fuel with isupply energy and the service has been terrible!I have had to telephone each time after inputting my meter readings to be told that the meter readings being shown were estimates made by them! Or they hadn't been "validated". It has been clear each time I have submitted the readings that nothing has happened because my account for electricity has remained the exact same credit figure each time. At one stage after an alteration made by them I had two meter readings showing for day time electricity for the same day! Some customer services staff are really rude and unhelpful and they do not return calls. I told one particularly rude member of staff that I had her name, the date and exact time of the call which I was going to make a complaint about and this call could be listened to. She very "cleverly" told me the calls aren't monitored! I am sick of the endless telephone calls to them. ...the fact they never get anything right and their rudeness. I am leaving them next month and I can't wait! No doubt between now and my actual escape I will have to endure more of this terrible treatment. Please do not be tempted to become a customer by their cheaper quotes....the time wasted on telephone calls and the way you are treated by the staff is just not worth it!

Do not be fooled by cheaper prices on comparison sites etc, it's just not worth the hassle. The sales process is fast and seamless, with short hold times on the phone and accounts being set up quickly (funnily enough). God help you though if you want to move house or have any issues with them. If you ever want to get through to iSupply on the phone, be prepared to be on hold for a minimum of 20 minutes before actually speaking to someone. You'll also need to make sure that it's between 9am and 5pm on a weekday too though as their phone lines are closed outside of these times. I'd highly recommend not calling post 4.30pm though as with the hold times you will not get through. Make sure you that you ask them to recalculate your direct debit on a regular basis unless you want to be hit with a huge bill. If you end up in the position where they owe you money as your account is in credit, good luck getting it back within 6 months! In short, if you do decide to make the switch to iSupply after reading this review and the countless others that highlight what a joke of a company they are, you must be mad.

Isupply Energy is the worst energy company on the market! They have overcharged my account by £200 and refused to listen and recalculate their charges even though it was all estimated! Then after closing my account and switching they sent me an additional bill for £50 when I hadn't had any my energy provided by them! They are a untrustworthy and upon looking into this through citizens advice and online they are doing this to thousands of people! I am so upset that I have allowed a company to do this to me without checking them out! PLEASE AVOID TO SAVE YOURSELF HUNDREDS OF POUNDS!

I have to say that this is the worst supplier that I have ever used and feel the need to review it. I was with this supplier for 2yrs and am unable to say anything good about it. After switching to a new supplier I received a letter in the post demanding a sum in excess of £200 for my energy use,this was despite having already paid monthly by direct debit. During the course of my contract I informed this firm that I was unable to provide a reading from my meter as I was unable to read it as it had been installed as a smart meter,something which Isupply don't yet use. I received no help from them and my readings were just rejected. They failed to adjust my direct debit payments and at the end I was issued a large bill. Whilst challenging this I was issued 2X late fees and a FINAL DEMAND letter threatening court action against me ! I am 52 years old and have never missed a payment or been in bad debt and to be threatened like this is nothing short of disgusting. I have paid what's owed as I have gave up arguing and do not wish for bailiffs to come knocking. I am glad to see the back of them. PLEASE avoid this firm, there are too many complaints against this firm to be able to say "it's just me" !

I was overcharged by isupplyenergy after they had been sending me post to a different address. I paid the full amount and decided to switch providers. However, it has been almost a month and isupplyenergy have blocked both attempts to switch providers. They provide automated responses and I haven't been able to speak to a customer service advisor to ask why they are stopping the switch. I have left a message after 20 minutes on hold and told someone would ring me back but still no response. This is the worst customer service I have come across and they are also very expensive! Stay away from this company or you will be stuck with them.

Signed up to them recently with a cheap tariff and I am not happy with the communication and their website, utter garbage. The website is poorly designed and navigation is terrible. If you want to contact them via their website it is not intuitive and you will find it buried were most people will not find it. So if you struggle to contact them through the website then the other option is to use their 0330 number which is not free. The call is local rate with no definitive answer to how much per minute by landline or mobile. Spoke to someone for 9 minutes, call centre person seemed disengaged and not interested, who knows what that is going to cost me. Also I never realised that you get a quarterly statement so I have no idea if my account is in debit or credit. The meter reading system is rubbish. I have submitted gas readings and they have been rejected because they believe them to be too low which is a joke. I don't submit false readings. To be honest I cannot recommend this company, seems to be not customer focussed and transparent. Just try and google their contact email address, you will not find it! Try and find a free land line number to contact them and you will not find it.

i inherited this supplier when i moved into my house and they have been a nightmare. 12 months later i am finally done with them. my advise use a traditional suppier.

Left as they could not get anything correct through out my time with them, failed to set up new direct debits amounts resulting in not being able to renew, then failure to find money paid to them and failure to finalise the end bills to the correct dates. Communication Is awful, I am now making complaints and the complaints i have already made but have not been dealt with

Ok so they saved me money but quite frankly id rather pay for good service than save a few quid. They constantly reject meter readings, dont get back to you when you send queries, dont update you when adjustments are made and when I tried to leave they continued to take my direct debit. I guess you live and learn, I'll never go back to them, even for a huge saving.

I'm on holiday in Australia and am constantly being hounded for meter readings at 02:30 in the morning, when I try ‘Contact Us’ the best I can get is an 0330 number, I’m not about ring Great Britain from Australia so I thought I would tell them I’m on holiday via email. Not a chance, I will be switching when I get back home. KP Birmingham

Since joining last year my electricity payments have doubled £70 to a suggested £140????? I am never going to use this company again!

Stay well clear. They are cheap yes, but the hassle is not worth the pennies you save. They also make statements they do not keep. I am still waiting for my refund after 2 months for renewing my contract after moving home. They constantly bombard you to send meter readings then reject them.............. If you like hassle go with them. If you don't stay well clear, I'm constantly threatening to cancel my direct debit only to be told if I do I'll be charged £10. The reason I am cancelling my direct debit is glossed over. STAY WELL CLEAR

It is now ll months that I joined this company, from day one I have experienced problems with my electricity account and the completely shambolic way in which they attempted to resolve the issue. We tried to get them to give us the figure that we owed them they were unable to works out usage. Contacting them was a nightmare we spoke to them on the phone after waiting anything up to an l hour. Sorry was the word commonly used but nothing was achieved. Communicating via the internet was useless sorry again but the issue wasn't resolved complaints seemed to sort the problem 6 months into the contract. But NO there was another problem. They are still unable to give me a figure or up to date statement although the meter has been read officially and by me. I am now changing supplier it may be more expensive but, I know that they will give me a stress less time. When my present company heard they threatened to stop me changing as iowed money. They couldn't grasp the idea that I had not received an up to date statement from them and had paid direct debits every month. The customer service colleague ignored.this fact and went in aggressively to stateif I continued to leave I HAD to pay an fee. I would pay anything to get rid of this company. HURRAH in 4 weeks I will see light at the end of this tunnel. GOOD RIDDANCE I supply. GO WITH THIS COMPANY AT YOUR PERIL
