I am in the process of making an official complaint to OFGEM. I have contacted Bulb on a few occasions and no one has got back to me.

I suspect that Bulb has incorrectly charged me over a period of about 7 months. The account charges were compared to 2 previous energy suppliers I spent over a year with consecutively, totalling 2 years of supplied energy.

When the combined cost of energy used with the above-mentioned suppliers is compared to that of Bulb, the difference in cost is astronomical. I also had one less appliance than I did with the previous energy suppliers when I joined Bulb.

On top of this, the cost of energy spent at each supplier is roughly the same, with the difference being only a couple of pounds. In regards to Bulb's charges, nothing makes sense and someone is ready to look into this for me while I wait for a response from OFGEM.

I have requested chat logs for every conversation I had with Bulb and my entire billing history in PDF format. This will help make things much more clear for me and the person helping me deal with this matter.

I don't know whether Bulb tampered with my previous supplier's smart meter and used it knowing full well that wasn’t part of our agreement, or if someone's incompetence is the reason for my outrageous bills. Either way, I have to get some answers.

I'm happy to pay for the energy I have used, but I am 100% sure I did not use £2000+ worth of energy in just a couple of months. I have been with quite a few different suppliers and my usage has been roughly the same each time.

Since Bulb has continued to ignore my complaints, I have made a final one. If I don't hear from them in 14 days, I will make an official complaint to OFGEM. I have gathered energy bills from my 2 previous suppliers who supplied energy at the same address, and I will need some answers as to why there is such a big difference between them and Bulb.

I'm with a 4th supplier now and the number of months I have been with them is approaching the number of months I was a Bulb customer and my total cost of energy so far is only a fraction of what Bulb is trying to charge me.

With all above being said, I cannot recommend Bulb.
