Renew Contract Is Very Misleading
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

Incompetent
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! Avoid, Avoid, Avoid!
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!

I Supply Energy Review
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.

Scammers
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 Spoke To Someone Today And He Was Very Patient .
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!

Avoid At All Costs
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.

Avoid Or It Will Cost You £100s
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" !
Q&A
I have just switch to iSupplyEnergy from e.on when will I receive notes of this?
It can take a couple of months before your first bill, though they should have give you online access to your account within 28 days, so you can make payments and avoid a large bill.
My biggest advice to you is keep a good eye on your meter readings and if your balance goes in credit by more than one months payment, get it back quick or threaten to switch - it can take 3 months to get your money back.
Do they cater foreconomy 10?
Yes, they have a night rate 11pm-7am.
Has anyone managed to get a refund out of iSupplyEnergy for an excessive balance in credit, or when they've switched away? Do you need to have an active direct debit with them for this to happen?
I have managed to get refunds but it took a bit of hassling. I haven't moved away yet though, this was just when signing up to a new contract. I also have a Direct Debit so don't know if it's more difficult without.
