Understanding and Improving Your Credit Score in the UK

A good credit score is crucial in the UK for anyone looking to apply for a mortgage, loan, or even a mobile phone contract. It reflects your creditworthiness to lenders and can significantly impact your ability to borrow money and the rates you’re offered. This guide explores what a credit score is, factors affecting it, and practical steps to improve your score.

What is a Credit Score?

Your credit score is a numerical value that lenders use to evaluate the risk of lending you money. It’s based on your credit history, including how you’ve managed loans, credit cards, and other financial obligations. In the UK, credit scores are calculated by credit reference agencies (CRAs) such as Experian, Equifax, and TransUnion.

Factors Affecting Your Credit Score

  1. Payment History: Late or missed payments negatively affect your score.
  2. Credit Utilisation: The ratio of your credit card balances to their limits. High utilisation can lower your score.
  3. Length of Credit History: A longer credit history usually positively impacts your score.
  4. Types of Credit: A mix of credit types (e.g., mortgage, credit cards, loans) can improve your score.
  5. Credit Searches: Too many hard searches in a short period can indicate financial stress, lowering your score.

How to Improve Your Credit Score

1. Check Your Credit Report Regularly

Begin by obtaining a copy of your credit report from the major CRAs. You can do this in Upscore for free, click here to register. Review it for errors or inaccuracies, such as incorrect addresses, payments marked as late that were paid on time, or accounts that aren’t yours. Dispute any errors you find with the CRA.

2. Register on the Electoral Roll

Being registered on the electoral roll at your current address improves your credit score as it helps lenders verify your identity and address.

3. Make Payments on Time

Set up direct debits for bills and credit repayments to ensure you never miss a payment. Even one late payment can significantly affect your score.

4. Manage Your Credit Utilisation

Try to keep your credit utilisation ratio below 30% of your total available credit. For example, if you have a credit card limit of £1,000, try not to carry a balance of more than £300.

5. Limit New Credit Applications

Each time you apply for credit, a hard search is recorded on your report. Space out your credit applications and only apply for credit you need and are likely to get.

6. Build a Credit History

If you have little or no credit history, consider using a credit builder credit card or loan. These products are designed for people looking to establish or improve their credit. Use them responsibly by making small purchases and paying off the balance in full each month.

7. Keep Old Accounts Open

Older credit accounts with good payment histories can positively affect your score. Unless there’s a good reason to close an account (like avoiding a high annual fee), consider keeping it open.


Improving your credit score takes time and discipline, but the benefits are worth it. A higher score can open doors to better interest rates and loan terms, saving you money in the long run. By understanding how your credit score works and taking steps to improve it, you’re investing in your financial future. Remember, consistency is key to building and maintaining a healthy credit score.
