Answer:
I doubt you'll find a money-lender anywhere in the UK that will loan to benefit claimants. This is simply because state benefits are not a guaranteed income, as you could have your benefits stopped for a number of reasons - leaving you with no means to pay back the loan.
Your best solution would likely be a crisis loan from the DSS - which will be recovered from your benefit payments weekly over a 12-month period. HOWEVER - crisis loans need to be justified !
