A good beginner’s credit card guide should start with your purpose: a purchase card may offer an introductory rate, while a cashback card could suit regular spending if you repay in full. Compare the interest rate, annual fees, charges for overseas use and the representative APR, remembering that the rate advertised is not necessarily the one you will receive. Only borrow what you can afford to repay, and paying the full balance by the due date can help you avoid interest and missed-payment marks. Check eligibility before applying and use an FCA-authorised provider where possible.
