A complete scam, I was with bulb for 12 months and after those 12 months they sent me a final bill which was £1,200. I lived in a one bedroom flat on my own, just me. no way I used £1,200 worth of electricity, let alone on top of the £50 a month I was paying anyway. Attempting to resolve this through some awful customer service, I was told that they wouldn't do anything to check for a fault as I no longer live at the property. After a few more failed attempts to get this resolved through ombudsman, all I was given £200 credit and an apology for the awful customer service. So I have just had to pay £1,000 of money I did not have and struggled to pull together just to get this incredibly painful and stressful situation behind me. I will never be returning to Bulb and I suggest you completely avoid them, if you value your money.
