Hello Darrond,
Is your girlfriend aware that people Low Income / or Benefit qualify for a instant 20% discount.
I know this, because i have recently had to go on Jobseekers, and i knew that i would have a problem paying my supplier for gas and electric. I telephoned them, they were very helpful and told me about the discount.
Apparently the government brought it in, i think February 2008. If i had know last year i would have applied for the 20% as i was on a low income.
I know it doesn't help your girlfriends situation at the moment, but it will help her with her future bills.
I am with Southern Electric / Gas, which i think is also Scottish Power.
Southern Electric called it Energy Plus, so you will have to see if Scottish power call it the same.
I hope this will help your girlfriend in the future.
