Sorry Ummm, had to dive out.
To claim a crisis loan, it must be done over the phone.
You will need your NI number, they ask when you last received benefit and what have you done with it.
They will only pay out a certain amount until your next 'pay day'.
For example, you can ask for £100 but will only offer £60 say, but that is only at the end of the formalities.
They also know how much your last payment was down to the last penny.
If they say yes, and a giro is issued, you must go to the job centre where you sign on with acceptable ID.
Usually, but not always, they will tell you what PO to go to ash it. If you're not a regular, they should ask for ID.
If it was paid into a bank or post office, the DWP will have that on record.
