What is a credit score?

A credit score is a number that reflects your credit history and how you’ve managed borrowing in the past.

Lenders use it to help decide whether to offer you credit, how much to lend, and at what interest rate.


What affects your credit score?

Several factors influence your credit score. Some have a bigger impact than others.


1. Payment history

Your payment history is one of the most important factors.

This includes:

  • missed payments
  • late payments
  • defaults
  • CCJs

Making payments on time consistently can help improve your score, while missed payments can lower it.


2. Defaults and CCJs

Defaults and County Court Judgments can have a significant impact on your credit file.

They show lenders that a debt has not been repaid as agreed.

You can learn more about CCJs in our guide to what a CCJ is and how it affects you.


3. Credit utilisation

This refers to how much of your available credit you are using.

For example:

  • using a high percentage of your credit limit may lower your score
  • keeping balances lower may improve it

4. Length of credit history

The longer your credit history, the more information lenders have to assess your behaviour.

Closing old accounts may reduce the length of your credit history.


5. Types of credit

Having a mix of different types of credit (such as credit cards and loans) can sometimes have a positive effect, but this is usually less important than payment history.


6. New credit applications

Applying for multiple credit products in a short period can negatively affect your score.

This is because lenders may see it as a sign of financial difficulty.


7. Financial associations

If you have a joint account or financial link with someone else, their credit behaviour may also affect your profile.


How do debt collectors, CCJs, and bailiffs affect your credit score?

Debt collectors themselves do not directly affect your credit score.

However, the underlying debt may already be recorded on your credit file.

For example:

  • missed payments may appear on your report
  • defaults may be added
  • a CCJ may be recorded

You can learn more about how this process works in our guides on debt collection letters and bailiff action.


How can you improve your credit score?

Improving your credit score takes time, but there are practical steps you can take:

  • make payments on time where possible
  • check your credit report regularly
  • correct any errors
  • avoid applying for multiple credit products at once
  • keep credit balances manageable

You can find more detailed steps in our guide on how to improve your credit score.


How long does negative information stay on your credit file?

Negative information such as missed payments, defaults, and CCJs usually stays on your credit file for a set period.

This means that even if your situation improves, it may take time for your score to recover.

See our guide on how long defaults stay on your credit file for more details.


Does checking your credit score affect it?

Checking your own credit score does not affect it.

This is known as a “soft check” and is safe to do as often as you need.


Key takeaway

Your credit score is influenced by how you manage credit over time. While negative events such as missed payments or CCJs can have an impact, taking consistent, positive steps can help you rebuild your financial position.
