I'm confused. I've used both noddle and clearscore to check my credit record, with clearscore i have a good record - which i'd expect, i have never missed or paid a payment late, i'm not overusing my available credit (credit card is paid off and i don't use my next credit account which is £5k) I've had a £3k overdraft facility on my bank account which i've never gone into, had no problems financing my car with BMW finance. Infact, my car is the only real finance i have atm. I earn a decent wage too. However, with noddle, my credit score is 1/5 
I applied for the credit facility on paypal yesterday as it offers 4 months interest free on purchases of £150 or more, which i thought would be handy, yet i got refused credit. On digging deeper, they use callcredit as their credit reference agency, which unless i'm mistaken, noddle uses to check my score too. However, Noddle seem to have a few of my details wrong, my address was my old one from 3 years ago, and they still have me on the electoral register there, even though i registered on my current address when i moved in over a year ago.
How do i go about sorting this out as i feel a bit gutted that i've been turned down for a credit facility, yet i had no issue taking £18k of car finance, or any other finance for that matter.
