Zopa is a P2P money lending service that allows lenders and borrowers to deal directly with one another, cutting out the banks who act as middlemen.
Zopa works in the following way: the company first categorizes borrower credit grades with an A*, A, B, C or Y rating; then lenders make offers that vary by money amount and time period for persons with a certain credit grade, and borrowers can then agree the aggregate offered rate.
