I moved to Iresa about a year and a half ago and what a mistake that was! Yes, they were on the cheap side but I didn't realise that they were as bad as they are. Ok, granted, I do get the electricity and gas that I need, so there is no delivery issue (with me at least) but anything else is just dreadful. Their online portal is slow and very difficult/unclear to use, their bills are a shambles and let's talk about support and that billing for a second. At some point, over a year ago, from 1 invoice to the next I 'lost' an amount of almost £150. I opened a support ticket about what was happening and please correct ..... I'm STILL waiting for them to fix this. Support is horrendous and don't even try to call them as your in for a long (and useless) wait! Please, avoid at all cost ...as they may seem cheap but in this case there is a real reason and you'll be the one paying extra.

Had an invite from them to fit smart meters that I took up early in the new year. The gas meter leaked and I had to call out National Grid to fix. Emailed the company but received no response but still receiving requests for meter readings 4 months on and ever rising direct debit payments. Tried on numerous occasions to e mail, don't even consider trying to contact them by phone, like other customers being 90th in the queue is common. Not a great experience I will now write to the ombudsman to resolve this. Avoid this company it is shocking. Hopefully it will be forced to close down

Tried to call on the phone various times and was 95th in queue. One day was 65th and took 90 mins to speak to someone. Don’t even try to email them I am currently still waiting on a reply from 12 days ago. Trying to switch company’s at the moment but can’t becuase ive got £20 outstanding on my account. I just can’t get in touch with them to pay. Customer service is the worst I’ve came across. Would rather pay an extra £50 a month elsewhere with a company that you can actually speak to when you have an issue

If you're thinking of changing energy suppliers, I can highly recommend bulb. There ethos I have found is great with 100% greener energy and their customer service has been brilliant. If you are thinking of switching you can use my referral link - bulb.co.uk/refer/hitesh9783 - With this you can get a quote in 2 minutes on top of get a £100 credit if you switch to bulb. I also found If you use dual fuel you get a further £30 saving per year.    Bulb also charge no exit fees if you decide to switch from them and also pays your exit fees from your current provider.

brileant servis on time of date aplianc put where I wanted culd not ask for a better cervis thank u lads

These people took over my dual fuel at the end of February from British Gas. But because they have not taken my meter readings I am continuing to pay British gas & Iresa, and there is nothing I can do about it. Iresa are legally obliged to provide British Gas with the 'change-over of supplier meter readings'. But they wont. They wont answer any of the 14 emails Ive sent to 3 different departments so far. They wont give me my online account log in details and when they communicate it is always from a "no-reply" mail box. There is nothing I can do but pay both companies for my fuel. These people are ignorant in the extreme. Avoid like the plague for a happy life.
