I have transferred to bulb from EDF purely because of price. I contacted EDF last week and they said that my transfer date for electricity was 07/05 but my gas wasn’t transferring until 30/05. They said they didn’t know why and to ask yourselves. Yet a couple of days ago I had an email saying I’m 100% switched to bulb…slightly confused!
Also, I know you pay in advance with bulb but I was surprised to see my first direct debit taken in 03/05, yet my transfer date was 07/05 yet according to EDF gas not until 30/05. Was just surprised the direct debit was taken that early when a previous email said it would be 07/05 for first payment.
