If you have ever applied for a loan, a credit card, or even a mobile phone contract, you have probably come across the term “credit score”. But what exactly is it, and what can you do to improve yours? This guide explains the basics in plain language.
What is a credit score?
A credit score is a number, calculated by a credit reference agency, that summarises how you have handled borrowing in the past. Lenders use it as one of several factors when deciding whether to approve your application and what terms to offer. A higher score generally suggests a lower risk to lenders, while a lower score may mean applications are declined or offered on less favourable terms.
Your score is based on the information in your credit report, which records things like your accounts, payment history, and outstanding balances. It is worth knowing that different agencies may give you different scores, because each one uses its own method of calculation.
What affects your credit score?
Several habits influence your score over time:
- Paying on time. Late or missed payments are one of the most damaging things for your score. Setting up direct debits for at least the minimum payment helps you avoid slipping up.
- How much of your available credit you use. Regularly maxing out cards can signal that you are overstretched. Keeping balances comfortably below your limits is healthier.
- Applying for lots of credit at once. Many applications in a short period can suggest financial stress, so space them out.
- The length of your credit history. A longer record of responsible borrowing gives lenders more to go on.
- Being on the electoral roll. Registering to vote at your current address helps lenders confirm your identity, which can support your score.
How to check your credit report
You can request your credit report from the main credit reference agencies. Review it regularly and look for errors, such as accounts you do not recognise or incorrect payment records. If you spot a mistake, contact the agency and the lender concerned to get it corrected.
Practical steps to improve your score
Improving a credit score takes time — there is no legitimate overnight fix. But consistent good habits work:
- Pay every bill on or before its due date.
- Reduce existing balances rather than just moving debt around.
- Keep old, well-managed accounts open where possible.
- Avoid unnecessary applications for new credit.
- Consider building a history with a small, manageable form of credit if you have none — but only if you are confident you can repay in full.
Be wary of any company that promises to repair your credit for a fee. Nobody can remove accurate negative information from your report, and you can take all of these steps yourself for free.
Think of your credit score as a reflection of your financial habits rather than a grade to chase. Focus on borrowing only what you can afford and paying it back reliably, and the score will tend to look after itself.
