Ulster Bank typically offers loans to applicants with high credit scores. It's important to note that your credit record is just one factor that Ulster Bank considers. However, if you don't have a high credit score, you're very unlikely to get approved for an Ulster Bank loan.
A "Good" or "Excellent" credit rating would require a score of 881 or higher if you're referring to Experian's scale, 531 or higher if you're referring to Equifax's scale and 604 or higher if you're referring to TransUnion's scale.
