I decided to leave bulb after being with them for about a year. I was fed up of waiting for a smart meter so signed up with Utilita (PAYG) who offered me one and easy online top ups. A couple of days after the switch my electric turned off leaving me and my vulnerable daughter without. After contacting Utilita and checking the meter we discovered that Bulb had put a £109.66 debt on my PAYG meter which wiped out any credit I had resulting in the electric turning off. Utilita came out within 3 hours and replaced the meter with a smart meter so we could get the electric back on (this was a Saturday). After many live chats with Bulb who at first denied all knowledge of the this debt, they finally admitted that they had made a mistake collecting the standing charges and they did indeed put this debt on the meter when I left. Strange how they noticed this mistake the day I left and not during the year I was with them.
I am happily with Utilita now with Smart PAYG meters with a proper informative account page and online top ups.
