Hello fellow mumsnet people!
I came across this new energy provider called Bulb and I must say that I am very pleased with my Bulb subscription. Great company and amazing customer service. It is painless to switch.
They also pay your exit fee. 
So glad I moved away from my previous provider. They were always so difficult to reach. 
And even better, they have an offer so you get £50 off when you sign up to Bulb energy! If you don't like it, you can always switch back, though I don't think you will need to. Use this link to get renewable energy with Bulb and get £50 off on your booking.

Bulb will also pay your exit fee for existing energy provider. Great customer service and cheapest rates. What are you waiting for mamas? Switch and save the environment and lots of money for yourself. 
Let me know your experiences in the thread below! :)
