My experience with bulb was disasterous. I swapped to them on the green consience thing and that they were supposedly good on price. After a yearish I started to find there bills creaping up and up. First of all I thought ok lets put a smart meter in see if that helps? However, on a daily basis all we did was look in horror at the cost. So I decided move to another supplier. First thing I did was pay my account up to zero. Based on the what my online account told me, I assumed from the smart meter readings and the meter readings I had given prior. I then carried out an online swap to another company. To my horror Bulb presented with a new bill one month after paying my account to zero of £480???. I still have nothing more than it was a mistake on previous billing as an explanation??? They told me was it was a consolidated bill taking into account mistakes made on previous bills?? To really rub salt in the reads were estimates. Do not bother with a smart meter fom bulb its pointless and dont bother giving them reads they seem to ignore them? In short DO NOT TRUST them to bill you correctly. They have done little to resolve the situation and as an ex-customer they dont dont really seem to care. My advice think twice, think thrice before moving to bulb.
