I recently joined bulb as I heard great reviews from friends about the ease of paying bills with them. It was every easy to switch, we just had to fill out a form online and it was done! All we have to do now is input our gas and electricity meter readings every few months and they calculate our bills. If we overpay our account gets credited with the overpayment amount, ready to be used for the next bill payment. I would definitely recommend bulb to everyone as it is easy to transfer and very easy to use.
