The low down on credit cards

There’s a lot of information out there about credit cards – including some pretty common myths and misconceptions. We’re here to answer some of the biggest questions out there so you can handle your credit card like a pro.

1. What protection do I get when using a credit card?

A major plus point for using a credit card rather than a debit card or cash is that you get extra protection on purchases thanks to Section 75 of the Consumer Credit Act.

As long as it’s not through a money transfer, if you make a purchase of between £100 and £30,000 on your credit card, and you are entitled to a refund from the supplier, you could claim it back from your credit card provider instead – giving you greater peace of mind when you’re shopping.

You're usually covered if the product is faulty, not delivered, or the company goes out of business, as long as the payment was made directly to the seller.

2. Can I withdraw money using my credit card?

Yes, you can withdraw money from an ATM using your credit card if you need cash and don’t have your debit card with you. It’s often called a cash advance.

However, keep in mind that since it’s not really what credit cards are designed for you may be charged a fee. The exact amount will depend on your credit card’s terms and conditions.

Your cash withdrawal may also be charged at a higher interest rate than regular credit card purchases and if you do it regularly, your credit rating might be affected.

3. What do I need to apply for a credit card?

Here are a few things you might need when applying for a Tesco Bank Credit Card:

  • Your address for the last 3 years
  • How much you earn in a year and your monthly take home pay
  • Your monthly mortgage or rent
  • Details of other credit cards if you’re planning to transfer a balance

Remember this might differ from provider to provider.

4. How do credit card payments work?

When you sign up for a credit card, your provider agrees to let you buy things on credit and pay the amount back in instalments, plus any interest.

Your provider will send you a credit card statement each month. This will include a minimum monthly payment that you must pay by a set date. You could also choose to pay a higher amount back or even pay your balance off in full. It’s worth remembering that if you only pay the minimum amount each month, it will take longer to clear your balance.

If you don’t meet your minimum monthly repayment, you might have to pay a charge or your interest rate might go up. Missing a few payments in a row could even cause a dip in your credit rating.

5. What is credit card APR?

APR stands for Annual Percentage Rate. This is the amount you will be charged for borrowing from your credit card provider each year. Your APR is made up of the interest rate on your credit card plus any arrangement or admin fees. That means that if you choose a card with a low APR, you’ll have less interest to pay each month and you might be able to lower your repayments or repay your balance sooner.

6. How many credit cards can I have?

Different lenders will have their own rules on the number of credit cards you can have, and it will also depend on your own individual circumstances. At Tesco Bank, it is possible to apply for a second credit card and you can have up to two credit cards with us at any one time. However, you can’t apply for a Foundation Credit Card if you already hold a different credit card with us.

When you apply for a new card, your credit card provider will look at the cards you have already, your credit history and how much other credit you’ve got to see whether giving you more feels risky.

Another little help: just because you get approved for more than one credit card, it doesn’t mean you should always take them. Having lots of credit could make keeping up with monthly payments tricky and make it harder to take out a loan or mortgage.

7. Why are credit ratings important?

When you apply for a credit card, your provider will want to know how well you’re likely to handle your credit. The easiest way for them to find out is to have a look at your credit rating, a score that’s worked out by looking at things like your credit history, past repayments and current borrowing.

A higher credit score shows that you have a history of being able to manage credit, making you a lower risk to lenders. As a result, you’re more likely to be offered better credit card terms, such as lower interest rates and higher credit limits, which might save you money on interest over time.

8. How can I get a credit card if I have no credit history?

A limited credit history – or even bad credit – doesn’t mean you won’t be able to get a credit card. In fact, some starter or foundation credit cards are designed to help you start building or repairing your credit rating.

If you can manage a credit building card well it can be a good way to improve your credit score. Doing things like making your monthly payments on time and staying within your credit limit are likely to help.
