About k-t-z.co.uk

k-t-z.co.uk was created with a single purpose — to give British players a trustworthy, no-nonsense resource for finding legitimate casino platforms that still accept credit cards. Since the UKGC banned credit card gambling in April 2020, the international market has filled the gap. It is crowded, unevenly regulated and full of misleading claims. We exist to separate substance from noise.

Why This Site Exists

Every month, tens of thousands of UK players search for casinos that accept credit cards. Most land on pages stuffed with affiliate links and zero genuine analysis. We saw that gap and built k-t-z.co.uk to fill it. Our readers deserve factual, first-hand information about which operators are worth their time and money, and which ones should be avoided entirely.

We cover one segment only: internationally licensed casinos that accept Visa, Mastercard and American Express from UK players. UKGC-licensed operators are outside our remit — they cannot process credit cards, so there is nothing for us to test. That narrow focus is exactly what lets us go deep on the platforms we do cover.

How We Evaluate Credit Card Casinos

Writing about a platform without having used it yourself is pointless. Every credit card casino on this site has been tested personally by our editorial team — real sign-ups, real GBP deposits by card, real gameplay sessions, real withdrawals. We never publish a review built on press releases or operator-supplied material.

Each assessment follows a structured framework covering seven dimensions:

Card acceptance — which networks genuinely process, whether Amex is supported, and whether any network gets quietly restricted after signup
Licence verification — cross-checking active credentials with Curaçao eGaming, Anjouan Gaming Authority, MGA or Antigua, with a clickable licence number in the footer
Withdrawal performance — timing card payouts directly, from £40 up to four-figure amounts, plus identifying hidden KYC delays
Bonus integrity — reviewing wagering requirements, maximum cashout caps, expiry windows and max bet per spin while a bonus is active
Cashier and banking — the breadth of methods, fees in both directions, minimum and maximum limits, and crypto support alongside cards
Game selection — library size, which studios are actually represented, live casino coverage and demo mode availability
Customer support — live chat response time tested during UK evening hours, plus the quality of answers to specific questions

Any platform failing on even one of those areas drops off the recommended list. We would rather show readers five properly vetted options than fifteen mediocre sites where the marketing copy hides the catches.

What Sets Our Reviews Apart

Most comparison sites rank by commission. We rank by what the platforms actually deliver under testing. That means an operator paying less can sit above one paying more, if the card withdrawals clear faster and the bonus terms are more realistic.

Every review includes a section on where the operator falls short. Not as a box-ticking exercise, but because no platform is flawless and you deserve to know the weaknesses before depositing. Rolletto Casino has the fastest card payout flow in our testing but a narrower game library than rivals. Rocketpot clears crypto withdrawals in under 30 minutes but keeps card acceptance limited. Those details go in the review, not buried in a footnote.

We also revisit our assessments regularly. Withdrawal times slip, licences change status, and bonus terms get tightened without notice. When an operator gets materially worse, it moves down the list or comes off it entirely.

Editorial Independence And Funding

k-t-z.co.uk is funded through affiliate commission. If you follow a link from here and open an account, we may receive a payment from the operator. It costs you nothing and never changes the terms you are offered.

What that arrangement does not buy: placement on the list, removal of criticism from a review, or inclusion for an operator that fails our checks. We turn down partnerships on those terms regularly. If an operator's card payouts are slow, we say so — including for brands we earn from.

A Word On Credit

Depositing with a credit card means gambling with borrowed money, and that distinction deserves more attention than most sites give it. A card deposit that lands instantly still has to be repaid at the end of the month. If your issuer treats it as a cash advance under MCC 7995, interest starts accruing the moment the transaction clears — no grace period, plus a fee. We flag that on every relevant page because it catches out more players than any bonus term ever will.

What We Never Do

Recommend a platform we have not tested with real money
List a casino without a verifiable licence from a recognised authority
Hide the risks of playing outside UKGC regulation — weaker consumer protection, slower dispute resolution and no GamStop coverage
Encourage anyone to gamble with money they cannot afford to repay, or to treat a credit line as a bankroll
