In the last ten years, I’ve gone from being a credit newbie (thanks, Aqua) to circling £30,000 in limits. For a long time I was playing the game: maximising cashback, going through every Amex card, chasing limits just to see how far they’d go. It was fun, until it wasn’t anymore. I’m so done with that.
Once I started being more intentional about the products I actually use, a new category emerged: the online‑only card. It sounds obvious in hindsight, but it took me a while to see it. The higher my limits became, the stranger it felt to hand those details over for a £5.99 purchase. Yes, credit protects you. Yes, that’s the whole point. But something about typing in a £10k card’s details for a tiny online transaction just felt wrong. Not stressful, exactly — just off.
The online‑only card
Here’s the idea: a small limit, but enough to cover all my online spending. It has to be FX‑free, that’s a hard rule for me. Whether I’m ordering something from abroad or renewing a domain, I’m not paying extra for the privilege. And it absolutely needs to live in a quiet little app that doesn’t try to nudge me into spending. No cashback, no points, no “earn £3 if you tap here”. Just a clean, reliable card that does what it’s supposed to.
This is the card for train tickets, Netflix, Amazon, contact lenses, one‑off insurance products, website and domain fees. Realistically, £30–£60 a month, sometimes more. That kind of spend has no business touching a £10k limit. So what am I really looking for: no FX fees, no rewards of any kind, and no current account attached to it — just a standalone credit‑card app.
Once you filter the UK market that way, the list gets very short.
My top two options
Basically only two cards made my list: the Halifax Clarity and Zable.
Those two are very different.. The Clarity is basically a British institution at this point, like Barclaycard Rewards or Club Lloyds. It’s the default travel card everyone seems to have whether they use it or not. It’s probably the cleanest, most straightforward card in the UK: it doesn’t charge you anything and it doesn’t really want to give you anything. Just a card with zero fees that says “have a great trip”.
Zable, to me, is the interesting one. A newish card from Lendable, it sees itself as a credit‑builder like Aqua and Capital One. But it’s the only one in that space that’s truly FX‑free. (Aqua and Zopa keep flirting with the idea but never fully commit, so why bother).
Once you stop seeing Zable as subprime and start seeing it as a tool, it becomes a different creature: a clean and modern standalone app, a limit that isn’t meant to grow, and zero distractions in the form of perks or offers. In other words, the perfect online‑only card.
