Having entered the murky world a few months ago of trying to get an adverse credit loan, I will also add that paying upfront fees is either a scam or just a waste of money that is ill afforded. Too many sharks out there willing to take advantage of people's dire financial predicament and profit from it. On top of that and the bad attitude or unhelpfulness from whoever you end up speaking with, first name only, you forfeit any control over how many credit checks are being done or knowing who by, any right to being informed, and any control over what is done with the information given. It is a lousy deal all round. Also beware the high rate premium call brokers that end up costing £22.50. Apparently they refund the amount after providing a copy of your phone bill, if not getting a loan, but I am dubious about that now.
Be aware that everyone you have contact with are just brokers or a marketing front, touting your circumstances for business, who do not care about the number of credit checks made and the negative impact on your credit rating. Even when you get the paperwork, it is just a trading name masking who the real lenders are. The paperwork is unlikely to be what was agreed over the phone, with exorbitant interest rates and terms and conditions that in effect say that they have the right to do anything and charge you anything, and you sign away any rights, only the obligation to pay whatever is demanded, whenever it is demanded. It shouldn't be legal but sadly it seems that it is.
A useful service through these forums or on the loans section of Moneysupermarket.com would be to provide a list of all the front names, the main business trading names, who they get the loans from, and the name behind them. Reveal how they make their money or charge, and give a rating based on comments given, with a forum section to comment on each. Can you, and will you do that Moneysupermarket.com? We could all pitch in with names and knowledge from our own experiences.
