I signed up and then realised LAMB were going to switch me to a more expensive tariff than what I could find myself. After cancelling this on 15th Oct and having received the confirmation from LAMB it was cancelled I thought I could get on with my life. But 13th DEC I received an email telling me I was being switched by a new provider. I rang and was told it was the peoples energy who was the provider I had declined to use. LAMB doesnt guarantee you cheaper bills however it does make a simple switching process much harder, will ignore your emails and waste your time.
