What is a credit score and how can I start building it?

As you start to plan your financial future, it's important to understand the concept of credit scores and credit files. In the UK, a credit score is like a grade given to you based on how responsible you've been with money. It can play a big role in whether or not you can get credit in the future, like loans, credit cards, and mortgages. It's worth noting that unlike in the US, lenders don't see your credit score, only your credit file. Your credit score can be a great way for you to benchmark how well your credit file is coming along, but it is your credit file that counts.

Your credit file is like a report card for your borrowing history. It includes info like your current and past addresses, credit accounts, and payment history. Lenders use this information to decide if they want to lend you money, and how much they're willing to give you.

Now, you may be wondering how to build your credit score. Here are some tips that might help:

  1. Open a bank account: Having a bank account is a great way to show lenders that you can manage your money responsibly.

  2. Get a credit card: Getting a credit card can also help you build your credit score, but it's important to use it carefully. Only spend what you can afford to pay back, and make sure you pay off the balance in full every month.

  3. Pay your bills on time: Paying your bills on time can also help you build your credit score. Late payments can hurt your credit file, so it's important to stay on top of them.

  4. Check your credit report: It's a good idea to check your credit report regularly to make sure everything is accurate. You can get a free credit report once a year from each of the three credit reference agencies in the UK (Experian, Equifax, and TransUnion).

When you apply for credit, lenders will look at your credit file to decide if they want to lend you money. They'll look at things like your payment history, how much debt you have, and how much credit you're using.

Credit utilization is a fancy term for how much of your credit limit you're using. For example, if you have a credit card with a limit of £1,000 and you've spent £500, your credit utilization is 50%. It's generally recommended to keep your credit utilization below 30% to avoid hurting your credit score.


As soon as you turn 18, you can start building a good credit history by opening a bank account in your own name, getting a mobile phone contract, or applying for a credit card with a low credit limit. However, it's important to use credit responsibly and make sure you can afford to pay back what you borrow. Start small and build your credit gradually over time. By doing so, you can establish a strong credit history that will serve you well in the future when you need to apply for larger loans such as car loans or mortgages.

In conclusion, building a good credit score takes time and effort, but it's worth it. A high credit score can make it easier to get credit in the future, and it can even help you get better interest rates. By following these tips and using credit responsibly, you can start building a strong credit score and set yourself up for a bright financial future. Good luck!
