Best Credit Cards UK — We Read the Small Print So You Don't Have To
Credit cards are tools. Used properly, they're interest-free borrowing, purchase protection under Section 75, and cashback on spending you'd do anyway. Used badly, they're a debt spiral at 20%+ APR. We've read the small print on dozens of cards so you sign up for the right one and avoid the traps.
0% Balance Transfer Cards Explained
If you're carrying credit card debt, a 0% balance transfer card is the single best tool for clearing it. You move your existing balance to a new card that charges no interest for a set period — currently up to 24 months. Every penny you pay goes to reducing the debt, not servicing interest.
The catch is the transfer fee, typically 1–3% of the balance. On a £3,000 transfer at 2.5%, that's £75 — but if you're paying 20% APR on the original card, you're paying £600 a year in interest. The maths is obvious. Just make sure you clear the balance before the 0% period ends, because the rate jumps to 20%+ overnight.
Rewards vs Cashback Cards
Rewards cards give you points (Avios, Nectar, etc.) for spending; cashback cards give you money back. The choice depends on your spending. If you spend £1,000 a month on a card, a 1% cashback rate earns you £120 a year. A rewards card might earn more if you fly frequently (Avios are valuable if you use them for premium flights), but the value is harder to realise.
The key question: do you pay the balance in full every month? If yes, rewards and cashback cards are free money. If you carry a balance, the interest dwarfs any reward — get a 0% purchase card instead and forget the perks. Rewards cards have higher APRs, so they're strictly for people who clear the balance.
Travel Credit Cards
Travel credit cards are designed for use abroad. They don't charge the 2–3% foreign transaction fee that standard cards add, and some offer competitive exchange rates. Over a week's holiday spending £1,000, that's £20–£30 saved in fees alone — enough for a decent meal.
Some travel cards also offer no cash withdrawal fees abroad, but beware — cash withdrawals on credit cards accrue interest from day one, even on 0% purchase cards. Use the card for spending, not for ATM withdrawals. And always pay in the local currency when given the choice — the retailer's conversion rate is always worse than your card's.
How to Compare APR (and Why It Matters Less Than You Think)
APR (Annual Percentage Rate) is the headline number on every credit card comparison. But it only matters if you carry a balance. If you pay in full every month, the APR is irrelevant — you never pay interest. The cards with the best rewards have the highest APRs, which is fine if you're disciplined.
What actually matters when comparing: the 0% period length (for balance transfers and purchases), the transfer fee, the rewards/cashback rate, and the foreign transaction fee (if you travel). Use comparison sites to filter by what you need — a 0% balance transfer card is a very different product from a travel rewards card. Don't compare them against each other; compare like for like.
If you carry debt, get a 0% balance transfer card and clear it before the period ends. If you pay in full, a cashback or rewards card is free money. If you travel, get a card with no foreign transaction fees. And whatever you pick, use a comparison site — never just accept your bank's offer.
