It was very easy to change supplier. It took only minutes in the end and Bulb then did all the hard work. They'll even cover exit fees if you have them.
Today (28th June 17) Bulb again passed on wholesale energy price savings to all customers. No other energy supplier has done this in 2017.
I've always been unsure about changing, then I read some reviews and I thought I'd give it a go. So glad I did change. I'm saving loads already and Bulb have just lowered their rates, the first to do it in 2017.
They have renewable sourced electricity and we can all refer friends and family. If you'd like to start with a £50 credit and start saving about £200 a year in costs, by all means cut and past the following link. Just remember to take out all the brackets around those dots.

Finally the customer service, what can I say but it is second to none. Very personal and easy to speak too.
If you get around to it, see how it goes and get your £50 start up credit. It's all yours.
