How Different Lenders View You
Different lenders prioritise different factors when assessing your file:
What Each Lender Focuses On
| Lender Type | Main Concerns |
|---|
| Mortgage lender | Stability, income, deposit size, existing commitments |
| Credit card provider | Payment history, credit utilisation, existing cards |
| Personal loan provider | Affordability, existing debt levels, income |
| Mobile phone contract | Payment history, CCJs, address stability |
| Landlord | CCJs, IVAs, bankruptcy, rental history, references |
Experian Score Thresholds
| Experian Score | Category | Typical Access |
|---|
| 961–999 | Excellent | Best rates and products available |
| 881–960 | Good | Most mainstream products |
| 721–880 | Fair | Standard rates, some restrictions |
| 561–720 | Poor | Limited options, higher rates |

A high Experian score doesn’t guarantee approval — lenders use their own internal scoring too. But improving your score reduces the number of lenders who decline you outright.
