Credit Cards, Overdrafts and Buy Now Pay Later

Credit is useful only when the repayment path is visible

Borrowing can spread a cost or provide short-term flexibility, but the available limit is not income. Before using credit, know what will be repaid, from which future income and by which date.

Several small facilities can create one large commitment. Review them together in your cash-flow calendar, including payments that have not yet appeared in the main bank balance.

Credit cards are revolving borrowing

A credit card has an agreed limit and a monthly statement showing the balance, minimum payment and due date. Repaying eligible purchases in full by the statement deadline can avoid purchase interest, but cash withdrawals and other transactions can follow different rules and charges.

When less than the full balance is paid, interest may apply and the remaining amount rolls forward. A card can therefore stay open without a fixed completion date unless you create one.

An overdraft is debt inside the current account

An arranged overdraft lets the account fall below zero up to an agreed limit. Interest can make regular use expensive, and incoming pay may simply return the account towards zero rather than becoming available for the new month.

An overdraft is often repayable on demand and the provider can change or remove the facility under its terms. Treat it as borrowing, not as part of your normal salary or spending allowance.

Buy Now Pay Later is a credit agreement

Buy Now Pay Later may split a purchase into instalments or delay the full payment. Even when the advertised cost is interest-free, the future payments compete with rent, food and other commitments on their due dates.

Since 15 July 2026, the FCA regulates Deferred Payment Credit offered by relevant lenders, with stronger affordability, information and support protections. Not every pay-later arrangement is structured in the same way, so check the provider, agreement date and live FCA information rather than assuming identical protection.

Compare cost, timing and protection separately

For each facility, record the APR or charges, payment dates, balance, limit, late-payment consequences, promotional terms and any purchase protection. A zero interest rate does not remove the risk of having too many payments due at once.

Check whether a provider is authorised using the FCA Firm Checker where regulation applies. Read the agreement and do not rely on a retailer's checkout summary as the complete explanation.

Recognise when short-term credit has become structural

Warning signs include using one facility to pay another, remaining overdrawn through most of the month, paying only minimums without a reduction plan, or using BNPL for essentials because cash is not available.

These signs do not call for shame. They call for an honest budget, a complete debt map and early support. Contact the provider and use free debt advice before missed payments multiply.
