How Debt Affects Your Credit Score and How to Improve It

Your credit score plays a crucial role in your financial life. It influences your ability to get loans, credit cards, mortgages, and sometimes even affects rental agreements or job applications. One of the biggest factors impacting your credit score is how you manage your debt. In this post, we’ll explain how debt affects your credit score along with some practical tips to improve it.

What is a credit score?

A credit score is a number that represents your creditworthiness, based on your credit history and financial behaviour. In the UK, scores usually range between 0 and 999 (or similar scales depending on the credit reference agency). The higher your score, the more likely lenders are to trust you with credit.

There are three main credit agencies, TransUnion, Experian and Equifax. While your scores are likely to flag similar things, your actual scores are likely to differ between the three agencies.

How debt affects your credit score

1. Credit utilisation ratio

This is the percentage of your available credit you’re currently using. If you have a credit card with a £2,000 limit and your balance is £1,800, your utilisation is 90%. High credit utilisation signals to lenders that you might be over-reliant on credit, which can lower your score. Ideally, keep utilisation below 30%. So if your credit card company offers a higher limit, accept it, but don’t use it.

2. Payment history

Your record of paying off debts on time is one of the most important factors. Missed or late payments can significantly harm your credit score and stay on your report for up to six years.

3. Total debt amount

While having some debt isn’t bad, a very high total debt compared to your income can be seen as risky by lenders and impact your creditworthiness. They may think that you’ve got a lot to pay back and might not be able to afford to take out more debt.

4. New credit applications

Applying for multiple new credit products in a short time can reduce your score. Each application results in a ‘hard inquiry’, which lenders see as a sign of financial distress. This also includes bank account applications, so try not to change your bank account too regularly.

5. Length of credit history

Longer credit histories with consistent repayments can boost your score. Frequently opening and closing accounts or having a short credit history may lower it.

How to improve Your credit score

1. Pay your bills on time

Always aim to make at least the minimum payments by the due date on all your credit agreements. Setting up direct debits or reminders can help you avoid missed payments. It’s always better to pay more than the minimum payment if you can afford to.

2. Reduce your credit card Balances

Try to pay down outstanding balances, especially if your credit utilisation is high. Paying off debt reduces risk in the eyes of lenders and can quickly improve your score. It shows you’re reliable and will pay back your debt.

3. Avoid applying for multiple credits at once

Only apply for credit when necessary, and space out applications to avoid multiple hard inquiries in a short period.

4. Check your credit report for errors

Request a free credit report from UK agencies like Experian, Equifax, or TransUnion at least once a year. Dispute any inaccuracies that might be unfairly damaging your score. This includes wrong addresses or missed payments which are incorrect.

I moved house and notified the council but they didn’t let credit agencies know. So I had a phone contract and bank account application denied as my address didn’t match what the credit agency had noted down. This mistake made my credit score drop and I had to spend a lot of time sorting it out.

5. Consider a credit builder card

If your credit score is low or you have little credit history, a credit builder card can help you demonstrate responsible borrowing when used wisely.

6. Keep older credit accounts open

Unless there’s a compelling reason to close them, keeping old credit accounts open can lengthen your credit history, which is beneficial.

How Debt Affects Your Credit Score

Managing debt carefully is key to maintaining and improving your credit score. Regularly checking your credit report, paying bills on time, and keeping your credit utilisation low can help you build a strong credit profile, opening doors to better financial opportunities.
