I switched to Bulb from one of the "Big 6" providers just over 3 years ago as I wanted to use cleaner energy and was fed up with the customer service. Bulb were recommended by a friend and we have been very happy with the service as a whole from day one. Everything feels simpler and less stressful when dealing with my energy supply. I moved house 4 months ago and also brought Bulb with me! Highly recommend!
