What is a Credit Score and Why do they Matter!?

When it comes to applying for a mortgage, your credit score is one of the most important factors that lenders use to determine whether they will approve your application. A good credit score can increase your chances of securing a mortgage with a competitive interest rate, while a poor score can limit your options and lead to higher borrowing costs. In this article, we’ll explain how credit scores work, how lenders use them, and offer tips on how to build, maintain, and recover your credit score.
What are Credit Scores and how are they used by Lenders?
Credit scores are numerical representations of your creditworthiness. Lenders use them to assess how likely you are to repay borrowed money. The score is based on the information in your credit report, which tracks your financial history, including credit card payments, loan repayments, and other borrowing activity.
When you apply for a mortgage, lenders will typically perform a credit check through one of the three main credit reference agencies:
- Experian
- Equifax
- TransUnion
Each agency uses its own scoring model, but generally, a higher score indicates that you are a lower-risk borrower, which can make it easier for you to access credit. Mortgage lenders review these scores to help them decide whether to lend to you and under what terms.
How to find out your Credit Score
Before applying for a mortgage, it is important to know if there are any adverse markers on your credit score. You can easily check it for free with each of the three major credit referencing agencies, with many agencies also offering free trials for monitoring your credit score. Additionally, several online services provide free access to your score from one or more agencies, allowing you to stay on top of your financial health.
How to build and maintain a good Credit Score
Building and maintaining a good credit score doesn’t happen overnight, but with some consistent habits, you can improve your financial standing:
- Pay Your Bills on Time: Timely payments are the most important factor in maintaining a good credit score. Set up direct debits or reminders to ensure you never miss a payment.
- Keep Your Credit Utilisation Low: Your credit utilisation ratio – how much of your available credit you’re using – should ideally be below 30%. This shows lenders that you’re not overly reliant on credit.
- Avoid Multiple Credit Applications: Each time you apply for credit, a “hard search” is conducted on your credit file, which can negatively impact your score. Limit your applications to necessary ones and space them out over time.
- Check Your Credit Report Regularly: Errors in your credit report can drag your score down. Regularly reviewing your credit report helps you spot mistakes, such as missed payments that might not be yours.
- Keep Older Accounts Open: The length of your credit history is another factor that can positively influence your score. Keep older accounts open, even if you no longer use them, to show a long, stable borrowing history.
Common Issues that can impact your Credit Score
Several common issues can negatively affect your credit score, making it more challenging to secure a mortgage:
- Missed or Late Payments: Regularly missing payments on credit cards, loans, or utility bills will significantly damage your score. Lenders view missed payments as a sign of financial instability.
- High Credit Utilisation: Using a large portion of your available credit can be seen as a sign you are under financial strain, and this will likely hurt your score.
- County Court Judgments (CCJs): A CCJ is a legal decision made against you for failing to pay a debt. Having one on your record can severely impact your credit score and ability to secure a mortgage.
- Bankruptcy or Insolvency: Declaring bankruptcy or going through an insolvency process can stay on your credit file for up to six years and can significantly reduce your credit score.
- Too Many Recent Applications for Credit: Multiple credit applications within a short period can signal that you’re struggling financially, which will hurt your score and make it difficult to obtain a mortgage
How to Rebuild a Damaged Credit Score

If your credit score has suffered, don’t panic. There are ways to rebuild it over time:
- Start by Paying Off Existing Debt: Focus on paying off outstanding debts and avoid taking on new credit. Paying off high-interest debts first is often a good strategy.
- Settle any County Court Judgments (CCJs): If you have any CCJs, settle them as quickly as possible. After paying them off, you can request to have them marked as ‘Satisfied’ on your credit report, which will reduce the damage they cause to your score.
- Consider a Credit-Builder Credit Card: These are cards designed to help people with poor or no credit history improve their score. They tend to have higher interest rates, but if used responsibly, they can be a useful tool.
- Get on the Electoral Roll: Being registered to vote shows lenders that you are a stable resident at your current address, which can positively impact your credit score.
- Use a Credit-Repair Agency (with Caution): While some companies offer credit repair services, be cautious as they can sometimes charge high fees without delivering results. Always research the company thoroughly before signing up for their services.
