3. You have a limited credit history
To be accepted for credit, you have to show you can effectively manage it, which is harder to prove if you have a limited credit history. You need at least one account that requires credit, open for six months, to generate a credit score.
You can show credit lenders that you can effectively manage credit by managing your payments on your utility bills, an overdraft (including an overdraft on a student account) or even a phone contract. Once you’ve built up your credit file, you’re more likely to be accepted for a credit card in the future. A credit building card might be something to help you build your credit file.
