There isn’t a specific credit score you need for a mortgage, and that’s because there isn’t just one credit score.
When you make an application for a mortgage or other type of credit, lenders work out a credit score for you. This is to help them decide if they think you’ll be a risk worth taking - if you’ll be a responsible, reliable borrower and likely to repay the debt. Usually, a higher score means you’re seen as lower risk – the more points you score, the more chance you have of being accepted for a mortgage, and at better rates.
