Common Questions

Should I Always Use Credit Card?

Not always. Use credit card for:

  • Larger purchases (£100+)
  • Online shopping
  • Travel bookings

Use debit card for:

  • ATM withdrawals
  • Very small purchases
  • If overspending is a risk

Can I Get Section 75 on Debit?

No. Section 75 Consumer Credit Act protection only applies to credit cards. Debit cards only have chargeback, which is weaker.

What If I Can’t Get a Credit Card?

OptionDetails
Credit builder cardHigher interest, easier approval
Prepaid cardsNo credit, no Section 75
Chargeback on debitSome protection, not as strong

Is Paying by Credit Card Bad?

Only if you don’t pay the full balance. If you pay in full monthly:

  • No interest charged
  • Better protection than debit
  • Can earn rewards
  • Builds credit score

Decision Framework

Use Credit Card If:

  • Purchase is £100 or more
  • You’re shopping online
  • You’re booking travel
  • You can pay full balance monthly
  • You want maximum protection
  • You’re renting a car

Use Debit Card If:

  • You’re withdrawing cash
  • Purchase is small (under £100)
  • You’re worried about overspending
  • Merchant doesn’t accept credit
  • It’s a direct debit payment

Summary

Card TypeBest ForAvoid For
Credit cardPurchases £100+, online, travel, rewardsATM, if overspending risk
Debit cardATM, daily small purchases, controlLarge purchases needing protection

The smart approach: Use credit card for purchases (pay in full monthly) to get Section 75 protection and rewards. Use debit card for ATM and when spending control is important.
