Your best bet is to look here: http://www.moneysupermarket.com/LoansP/PersonalLoansAssessment.asp

Here you can very quickly compare the various loan companies and clearly see what the cost of the loan will be so you can try various combinations. It is important when you get a loan though to consider you financial record - any black marks against your name and you will either find it tricky or more expensive to borrow money. Always keep an eye on the loan percentage rate when finally applying and also remember that for every application you make a credit check is made on you. The more credit checks done the lower your rating gets (credit checks are recorded).

Good luck!
