Bulb have been disappointing for several reasons. They persistently send emails regarding the installation of a Smart Meter, even though they are aware that I am a tenant and I always submit meter readings. They have not honoured the £50 refer a friend payment for me or my friend and have raised prices significantly. They don't seem to be properly addressing the issue of off peak electricity tariffs for electric car-charging yet either, so are behind other suppliers. I'll be switching suppliers when I move out of this property.
