Hi Seemore-
We have many threads on our forums regarding Yes loans, I would suggest you read them by searching on the icons above, however the feedback is not positive from our users.
Here is an example - the upfront fee you pay does not guarantee you a loan - it's only a "pre" approval.

If you have adverse credit, or even a little "blip" on your profile then shop carefully and use the correct lenders. Your own bank is a good place to start because they know who you are and have a relationship with you.
If you then have to use a broker I would suggest using a broker called UCC. They charge no upfront fees and they search all the lenders that cater for people with less than perfect credit. If you want help with UCC please call our team on 0870 027 0269.
I hope this helps,
Many Thanks,
Gareth Sharp
