My Zembl (8)

I've moved properties since setting up an energy account with you, how can I change this?

My phone number or email address have changed, how do I update this on my Zembl account?

What personal details must I provide to get an energy tender?

I've not yet received my welcome pack/bills from my new retailer, why is this?

If there is a fault will it be handled differently if I change energy retailers?

I'm no longer looking after the energy for the property, what should I do?

I need to update my payment details or set up a direct debit?

I need to file a complaint regarding an existing account, how do I do this?
