In this guide, we’ll focus on the benefits of using a credit builder card, the do’s and don’ts, what to look for when comparing credit cards, and who this solution is suitable for.  It’s important to always spend carefully when using a credit card and try to pay back the full amount before the end of the month.

What is a Credit Builder Card?

Credit builder cards are designed to show that a person can borrow small amounts of money and repay the balance on time, avoiding going below the allocated credit limit to build their personal credit. Credit limits usually range between £50 and £1,500, while interest rates can go up to 39.8% APR.

For credit-building purposes, the full balance must be repaid on time each month, which also helps avoid paying additional interest. To help with this, it’s advised to set up a direct debit so repayment dates aren’t missed. However, it’s also important to remember that a credit card can also damage your credit score if you miss payments, max out your limit, or get in debt.

Why is a Good Credit Score Important?

A person’s credit score dictates whether a person will be accepted for a loan, car finance, or a mortgage, how much a person can borrow and the interest rate they’ll be charged. A good score signals to lenders whether someone is a responsible borrower.  Your credit can even have an impact on whether you are eligible for a mobile phone contract.

Building Your Credit Score with a Credit Card

If used sensibly, a credit builder card can be a valuable tool in repairing and building your credit, but to do this effectively, there are some best practices that need to be followed.

1. Ensure you pay the balance off on time by setting up a direct debit, and try to pay the balance off in full each month to avoid paying any interest.

2. Don’t exceed your credit limit. If possible, to avoid any impact on your credit score and to avoid fees. Aim to stay 25% below the limit to show you’re not reliant on your credit card.

3. Avoid using your credit card to withdraw cash. This can result in paying high withdrawal fees, and using your card for this purpose could be seen as a negative for some credit companies.

Types of Credit Cards

Although dedicated credit builder cards that have a low credit limit and high APRs are the most effective way of building credit, other options may be more suited to a person’s present situation.

  • Balance Transfer Credit Cards: These credit cards allow people to consolidate debts to reduce the amount of interest they pay each month, while also making it easier to manage their monthly repayments.

  • Purchase Credit Cards: A standard credit card that allows people to spread the cost of purchases, often with an interest-free period. Providing payments are made on time, it’s possible to spread the cost of large purchases without incurring any additional fees.

  • Credit Builder Cards: Low credit/ high APR credit cards designed for borrowing small amounts with full repayment each month.

  • Credit Cards for Poor Credit: Specific cards aimed at people with no credit history or bad credit, enabling them to borrow money at short notice, typically with a high APR.
