How do I find out my account number

[Laura30]

Could you please tell me how I find out my account number as I am filling a change of name form in and it requires this information

If you work through this guide, you should be able to find your account number Guide: How do I get to the 'Download Bill' page? 

Edited to add this picture for clarification. On the last page, right hand side, you will see account number.
