By improving your credit score you can qualify for better loan rates and credit cards. While improving your credit score takes time and effort, it's worth it in the long run. There are various ways to improve your credit score, including:
checking your credit report to make sure that all information is correct and up-to-date. You can do this for free with credit reference agencies like Experian, Equifax and TransUnion
paying your bills on time. Late payments may harm your credit score so it’s crucial that you pay your bills on time
where possible, avoiding applying for too much credit. Applying for too much credit in a short period of time can have a negative impact on your credit score. Only apply for credit when you need it and make sure to shop around for the best rates
using credit-builder products. Credit-builder products (like credit-builder credit cards and credit-builder loans) are designed to help you improve your credit score
