Recommend bulb

Hi, i was originally a bulb customer at my previous address and requested that I stay a customer at my current address I recommend that the person moving into my old address switch to bulb, snd they have done but i still haven’t seen the £50 credit on my account"

If your previous property was already supplied by Bulb, then there would be no switch taking place. The new occupier just takes over the account, so no referral is applicable.
