Withdrawing extra funds

How can I get money back from my account? The bulb chat is always busy and unavalible.

One way or another you have to contact Bulb. That’s the only way to do it.

Phone, webchat, or email.

In addition to the advice from Hooloovoo you can reduce your direct debit payments down to say £5 to enable you to start eating into your credit. This is on the assumption your bills accurately reflect the meter readings which you have supplied to Bulb.
