I've tried lots of energy companies over the past few years, and I have to say Bulb have been by far the best. My bill is very cheap each month, the live chat service is impeccable when I need help, and I can always refund credit on my account instantly when it exists. Like everyone else, I have a code for us both to get £50 (redeemable as straight cash if you want it!). Help out a poor student! (www.bulb.me/scottb7513)
