inb4 credit score doesn't exist.Bit of a bump.
I use ClearScore for my credit rating and have a score of 858 which I assume is pretty good. I notice that they can do an affordability score by linking your bank account and I'm wondering if I should? I'd like to get a personal loan at some point and curious if this will increase my chances?
Each bank will use their own criteria. The only thing you can do to improve it is to regularly use and pay in full your CC, be on the electoral role etc. If you have a CC it shouldn't be more than 50% utilised if possible.
