Re: Decent loaN Rates try the supermarket finance teams like marks and sparks and tesco . they always have loan sales on this time of year . (used to wrok in M&S financial services )
Zopa is a tricky one. Rarely find what you're after. Northern Rock do 5.8%. Moneysupermarket is the best to show you all the rates though. I know one firm does 5.7%. You won't get better than that.
