Low Deposit Casinos UK: The £1, £5 and £10 Reality Check (2026)

Five pounds. That is the entry price for a seat at most UK-licensed online casinos in 2026, and it buys you roughly the same legal apparatus that sits behind a £500 deposit: identity verification, affordability monitoring, segregated player funds and access to the Alternative Dispute Resolution scheme. The number on the deposit button is small. The machinery underneath it is not.

This page is about what happens after the fiver leaves your bank account. Not the headline bonus, not the “100 free spins” splashed across a landing page, but the actual arithmetic of low deposit casino play in Great Britain — which operators accept £1, £5 and £10, which payment rails make those amounts commercially viable, what the UK Gambling Commission requires of the brands that offer them, and where the terms quietly turn against you.

The UK low deposit market is not a charity aisle. It is a customer acquisition funnel dressed in budget-friendly language. That does not make it predatory by default. It does make it worth reading the small print before you tap deposit.

The £1–£10 Entry Point: What “Low Deposit” Actually Means in the UK Market

Low deposit is marketing language, not a regulatory category. The Gambling Commission does not define a “minimum deposit casino” or issue a special licence for brands that accept £1 stakes. What the Commission does is set the conditions under which any remote casino operating in Great Britain must function, and those conditions apply identically whether the first deposit is £1 or £1,000.

The phrase survives because it describes a commercial reality: some operators set their floor at £1, others at £3, most at £5, and a significant chunk at £10. That variation is not driven by player demand. It is driven by payment processing economics, bonus liability and the cost of regulatory supervision per account.

Why the £5 Floor Became the Default (and Where £1 Still Survives)

A debit card transaction carries a fixed authorisation cost plus a percentage fee. On a £5 deposit, the fixed element can eat 10p to 20p before a single spin happens. On a £1 deposit, the same fixed cost can consume a fifth of the transaction value, which is survivable only if the operator expects you to deposit again. That arithmetic explains why the £1 tier is dominated by bingo-led and slots-first brands with high retention models — Gala Bingo, Foxy Bingo, JackpotJoy, Sun Bingo and Rainbow Riches Casino all sit in that bracket — while sportsbook-first operators like William Hill, Betfred, Coral and Ladbrokes generally keep a £5 card floor.

Open banking changed the maths at the margin. A Pay by Bank transfer through a provider like Trustly or TrueLayer carries a flatter per-transaction cost than card interchange, which is why several casino-first brands — MrQ, PlayOJO, Casumo, 32Red and Grosvenor Casinos — have been able to sustain £3 or lower entry points through open banking rails rather than card. The payment method, not the brand logo, often decides the real minimum.

The Gross Deposit Limit Rule Nobody Mentions

From 31 October 2025, UK-licensed operators must prompt customers to set a financial limit before their first deposit, and the limit that matters for compliance is a gross deposit limit — a cap on total deposits over a period, without any offset for withdrawals. This is the piece low-deposit guides routinely skip. A player who deposits £5, withdraws £10, then deposits another £5 has a gross deposit total of £10, not zero. If the monthly limit was set at £10, the third deposit is blocked even though the player is net-positive.

For small-stake players the practical effect is usually mild. Someone depositing £5 a week has a gross total of roughly £20–£25 a month, which sits comfortably under any sensible self-set limit. The rule matters more for players who use low deposits as a trial run across multiple brands. Each account carries its own limit, and the Commission has not implemented cross-operator deposit limits at this stage. The protection is per-account. The discipline has to be per-player.

Best Low Deposit Casinos UK: The Shortlist That Survives Scrutiny

There is no shortage of pages listing “top 10 low deposit casinos.” Most of them recycle the same affiliate links and treat a £5 minimum as if it were a personality trait. The shortlist below applies a narrower filter: the brand must hold a current UKGC remote casino licence, the advertised minimum must be available on at least one mainstream payment rail without a promotional code, and the bonus terms must be discoverable before deposit rather than buried in a PDF.

How We Picked — and What We Threw Out

We excluded brands whose “£1 deposit” applies only to a promotional window that has already closed, and brands whose minimum resets to £10 once the welcome offer expires. We also excluded offshore operators accepting UK players under Curaçao or Anjouan licences. Those brands may advertise €10 or €20 minimums, but they sit outside the Commission’s jurisdiction, do not contribute to the statutory levy, and offer no access to IBAS or an equivalent ADR route if a payment dispute arises. A low minimum is not worth losing your dispute rights over.

The Operators Worth Your Fiver

MrQ runs a UKGC licence granted in September 2023 and has built its positioning around “no wagering, no nonsense” — free spin winnings from its welcome offer are paid without a playthrough requirement. The standard minimum sits at £10 on most rails, though the brand has historically supported lower entry points through Pay by Bank. The trade-off is a smaller headline bonus than the match-heavy packages at 888 or LeoVegas, but the absence of 35x–40x wagering on spin winnings is worth more than a larger number that cannot be cashed out.

PlayOJO launched in 2017 with a zero-wagering policy and has not moved off it. The welcome mechanic is typically 50 free spins on Book of Dead with a £10 minimum deposit, and everything won from those spins is paid in cash with no playthrough attached. The minimum is £10 across all methods, which means it does not qualify as a £5 or £1 site. What it does qualify as is the cleanest bonus structure in the low-deposit tier — no maximum conversion cap, no 40x rollover, no “bonus funds” silo that vanishes if you try to withdraw early.

Gala Bingo is the reference point for the £1–£5 bingo tier. Card deposits can start at £1 on promotional products, with a £5 floor on most standard methods and £10 on Paysafecard. The welcome offer is bingo-credit-heavy rather than slots-heavy — typically £20–£30 in bingo credit on a £10 first deposit plus a batch of free tickets — which suits players who actually want to play bingo rather than treat it as a side room next to the slots. The licence is UKGC, the deposit limits are standard, and the brand has been on the Virtue Fusion network long enough that its room liquidity is not a gamble in itself.

LeoVegas sets a £10 minimum on debit card and has run a “play £10, get 50 free spins” structure on Big Bass Splash in recent cycles, with 1x wagering on the spins rather than the 35x–40x that dominates the market. The deposit-match component, where offered, typically carries a higher wagering requirement, so the spin package is usually the better-value route for a small-stake player. UKGC licensed, mobile-first interface, and a game library that is broad enough to make the £10 feel like an entry ticket rather than a locked door.

888casino sits at the £10 minimum and is the brand most likely to appear in “deposit £10 get £20” or “deposit £10 play with £50” comparisons. The maths on those offers is less generous than the headline suggests: a £10 deposit triggering a £20 bonus at 30x wagering on the bonus alone requires £600 of play before the bonus converts. The brand is UKGC licensed and the games are audited, but the low-deposit entry is a funnel into a wagering obligation that is roughly sixty times the initial stake. Read the terms with a calculator, not with optimism.

£1 Deposit Casinos UK: The Cold Maths Behind the Cheapest Entry

A pound does not buy much in 2026. It buys even less inside a casino, where the house edge is already priced into every spin. The £1 deposit tier survives because the lifetime value of a retained player dwarfs the loss on the first transaction — not because the operator has suddenly developed a philanthropic streak. Understanding that framing is the difference between reading a bonus offer as a gift and reading it as an acquisition cost.

Who Genuinely Accepts a Pound in 2026

The £1 threshold is concentrated in bingo-led and slots-led brands rather than sportsbook-first operators. Gala Bingo, Foxy Bingo, JackpotJoy, Sun Bingo, Heart Bingo, Double Bubble Bingo and Rainbow Riches Casino all operate in the low-stake bracket where a £1 card deposit is standard practice. MrQ, PlayOJO and Casumo have built their positioning around low-friction entry, though their standard minimums have drifted toward £5–£10 on some rails. On the sports side, Betfred and Betway have historically run £1 promotional windows, but the standard card floor at William Hill, Coral, Ladbrokes and Bet365 sits at £5.

The rail matters more than the brand. A £1 card deposit does not mean a £1 PayPal top-up, a £1 bank transfer or a £1 Paysafecard voucher. PayPal’s merchant configuration effectively rules out micro-deposits below £5 in most setups, Paysafecard starts at £10 in the UK, and open banking aggregators typically floor at £5 or £10 depending on the provider. A brand advertising “£1 minimum” is usually advertising the debit card route. If you plan to use anything else, check the method-specific minimum before you register.

The Wagering Trap on “£1 for 100 Spins” Offers

“Deposit £1, get 100 free spins” is the most efficient piece of marketing copy in the low-deposit sector. It is also the one that requires the most arithmetic. A £1 top-up that triggers 100 spins at 10p per spin creates a nominal spin value of £10 — ten times the deposit — but the spin winnings are almost always bonus funds subject to a wagering requirement, not cash. At a 30x wagering requirement on a £5 spin-win pot, the player faces £150 of play before a withdrawal is possible. At 40x, it is £200.

The structural point is simpler than the maths: the £1 buys the seat, not the prize. Spin winnings at the £1 tier are frequently capped at a maximum conversion amount — £50, £100 or £250 depending on the operator — and the wagering requirement applies to the bonus balance, not to the £1 deposit. A player who runs the spins, clears the wagering and requests a withdrawal may find that the maximum cashout clause bites before the balance reaches their bank account. None of this is hidden. It is simply placed where most players do not look before tapping “claim.”

What a £1 Deposit Actually Costs the Operator — and Why They Bother

Take a representative £1 deposit on a 96% RTP slot. The house margin is roughly 4p per £1 staked. The operator needs about £1.25 of total wagering just to recover the processing cost of the deposit, and considerably more to cover the bonus attached to it. Add the 21% remote gaming duty on gross gambling yield and the 0.4% statutory levy that replaced the voluntary system in April 2025, and the effective margin on a £1 player drops further. The only way the tier works commercially is if a meaningful proportion of £1 depositors return and deposit again at a higher amount.

That is the honest reason the £1 button exists. It is not a loss leader in the supermarket sense. It is a customer acquisition cost with a regulatory compliance wrapper. The player’s job is to make sure the acquisition cost is not their own.

£5 Deposit Casinos UK: The Volume Tier Where Most Players Land

Five pounds is the Goldilocks number of the UK low deposit market. It is high enough to cover card processing costs, low enough to sit below the automated affordability flags that most operators run on new accounts, and round enough to make the bonus maths legible. The Commission’s 2023 consultation on remote customer interaction pushed operators toward lower initial exposure and earlier verification, and a £5 entry point fits neatly into that framework. It is a commercial choice dressed as a compliance one. Both readings are correct.

The Bonus Structures That Actually Convert

At the £5 tier, welcome offers split into three rough families. The first is the percentage match: deposit £5, receive a 100% match up to a cap, with wagering on the bonus. The second is the fixed spin bundle: deposit £5, receive a set number of spins on a named slot, with wagering on the spin winnings. The third is the no-wagering package, where the spin winnings are paid in cash and the operator recovers value through retention rather than playthrough. MrQ and PlayOJO are the reference points for the third model, and their £5–£10 entry points are the ones that survive a value comparison once the wagering maths is applied.

The match model is where the headline numbers inflate fastest. A £5 deposit triggering a £10 bonus at 30x wagering on the bonus alone requires £300 of play before conversion. At 40x on both stake and bonus, the requirement climbs to £600. Neither figure is unusual at the £5 tier. Both are sixty to 120 times the initial deposit. The operator is not hiding the requirement; it is simply presenting the bonus as the story and the wagering as the footnote.

Deposit £5, Get 100 Free Spins: Reading the Fine Print

A £5 stake yielding exactly 100 spins sounds generous until the per-spin value and the RTP are factored in. At 5p per spin, 100 spins represent £5 of nominal wagering — the same as the deposit. At 97% RTP, the expected return across those spins is roughly £4.85 before any wagering requirement on the winnings is applied. Add a 35x wagering requirement on the spin-win pot, and the expected value moves further away from the player. The spins are not a gift. They are a structured trial of the slot, funded partly by the deposit and partly by the operator’s acquisition budget.

The fine print that matters most at this tier is not the spin count but the maximum bet during wagering. Most operators cap bonus-play stakes at £5 per spin or £5 per hand, and exceeding the cap can void winnings. A player who clears the wagering requirement at £1 spins and then raises to £10 for a final push may find the entire bonus balance removed. The cap is not a suggestion. It is a condition of the bonus.

Betting Sites with a £5 Minimum — A Different Beast

Low deposit betting sites operate on different economics from low deposit casinos. A sportsbook can accept a £5 minimum because the margin on a single football bet is wider and the settlement cycle is shorter than a slots session. Brands like Bet365, William Hill, Ladbrokes and Coral commonly set a £5 floor on card deposits for sportsbook products, while their casino lobbies may carry a £10 minimum on the same account. The distinction matters if you are comparing “betting sites with £5 minimum deposit” against “casinos with £5 minimum deposit”: the same operator can appear in both lists at different numbers depending on which product you are funding.

£10 Deposit Casinos UK: The Sane Middle Ground

Ten pounds is where the low-deposit market stops pretending to be micro-stakes and starts behaving like a normal casino entry point. The bonus packages are larger, the wagering requirements are more visible, and the operators are more likely to be household names with full sportsbook integration. It is also the tier where the gap between the headline offer and the realistic value is widest, because a £10 deposit can support a £20 or £30 match without the operator losing money on the acquisition — which means the marketing team has more room to inflate the presentation.

Deposit £10 Play with £50 Slots: What the Match Really Demands

“Deposit £10, play with £50” is a standard construction at the £10 tier. The £40 uplift is rarely a straight cash match. It is typically a combination of bonus funds, free spins and sometimes bingo credit, each with its own wagering requirement. A £20 bonus at 30x wagering requires £600 of play; a £20 bonus at 40x requires £800. The £50 “playing balance” is real in the sense that it appears in the account. It is not real in the sense that it can be withdrawn without clearing the playthrough.

The no-wagering alternative at £10 is thinner but more valuable. PlayOJO’s 50 spins on Book of Dead and LeoVegas’s 50 spins on Big Bass Splash both sit at the £10 deposit threshold, and both attach either no wagering or 1x wagering to the spin winnings. The headline value is smaller than a £50 play package, but the conversion rate from spin win to withdrawable cash is dramatically higher. For a player who intends to withdraw rather than recycle, the smaller, cleaner offer is the better bet.

Bingo vs Slots: Where the £10 Entry Goes Furthest

Bingo-first brands stretch a £10 deposit further than slots-first brands in nominal play time, because bingo tickets at 1p–10p per ticket allow a session to last longer than a slots bankroll at 20p–50p per spin. Gala Bingo, Buzz Bingo and Costa Bingo all run £10-triggered welcome packages that include bingo credit and free tickets rather than slots spins, and the wagering requirements on bingo bonus are often lower than the 35x–40x standard on slots bonus. The trade-off is that bingo prizes are smaller and the house edge is structured differently. If the goal is time-on-site rather than upside, bingo is the more efficient £10. If the goal is a shot at a multiplier, slots are the only product that offers it.

Payments, Rails and Why Your Minimum Deposit Changes by Method

The payment method is the single most underrated variable in the low deposit market. A brand that advertises “£1 minimum” is almost always quoting a debit card figure. The same brand may require £5 for PayPal, £10 for Paysafecard and £5 or £10 for open banking. The variation is not arbitrary. Each rail carries a different cost structure, and operators price their minimums to keep the transaction economically viable.

Debit Card, Open Banking, PayPal, Paysafecard — A Practical Comparison

Visa and Mastercard debit are the default low-deposit rails. They settle instantly, the operator pays a fixed authorisation fee plus a percentage, and the minimum can be as low as £1 at brands that choose to absorb the fixed cost. Credit cards have been banned for UK gambling deposits since 14 April 2020, so any “credit card casino” comparison is obsolete in this market.

Open banking / Pay by Bank transfers through providers like Trustly, TrueLayer or PayByBank use account-to-account rails with Strong Customer Authentication. They carry a flatter per-transaction cost than card interchange, which is why some casino-first brands can sustain £3 minimums on open banking while keeping a £5 card floor. The deposit settles in seconds, and the withdrawal often returns through the same rail within 12–48 hours. The trade-off is availability: not every high-street bank supports every open banking provider, and a failed integration can push the effective minimum higher than advertised.

PayPal is the most widely recognised e-wallet in the UK market, but its merchant configuration rarely supports micro-deposits below £5. At brands that do accept £5 PayPal deposits, the withdrawal typically returns to PayPal before reaching the bank account, adding a step to the cashout timeline. For players who value dispute resolution, PayPal adds a layer of consumer protection that debit card deposits do not. For players chasing the absolute lowest minimum, it is not the rail.

Paysafecard is the outlier. The prepaid voucher model starts at £10 in the UK for most casino integrations, which makes it incompatible with the £1 and £5 tiers regardless of what the brand’s landing page says. It is useful for players who do not want to share bank details, but it is not a low-deposit tool in the sense the phrase is usually meant.

The Credit Card Ban and Its Aftermath

The 2020 credit card ban removed the most expensive rail from the UK gambling market and, paradoxically, made low deposits more viable. Credit card interchange on a £5 transaction was higher than debit card interchange, and the chargeback risk was greater. The shift to debit, open banking and e-wallets lowered the average cost per small deposit and widened the range of brands that could afford to offer £5 and £10 minimums. The ban was a consumer protection measure. It also happened to be good for the economics of the low-deposit tier.

Licensing and Safety: What a UKGC Badge Actually Guarantees

A Gambling Commission licence is not a badge you buy and forget. It is a set of ongoing conditions the operator must meet daily, with the threat of suspension or revocation if they slip. For a low deposit casino, those conditions shape everything from how the welcome offer is worded to how fast a withdrawal clears. The licence fee itself ranges from £3,000 for the smallest remote casino category to £30,000 and beyond for larger operators, which is why the low-deposit tier is dominated by brands that can amortise that fixed cost across a large player base.

The Difference Between a UKGC Licence and a Curaçao Licence

A UKGC-licensed operator must segregate player funds at the “medium” protection level or higher, publish a policy on how those funds are held, contribute to the statutory levy, and fund access to an ADR scheme such as IBAS. A Curaçao- or Anjouan-licensed operator accepting UK players sits outside the Commission’s jurisdiction, does not contribute to the levy, and offers no access to the UK’s dispute resolution routes. If a payment dispute arises at an offshore brand, your only realistic remedy is the operator’s own complaints process. That is not a theoretical difference. It is the difference between an adjudicator and an email inbox.

The licence also determines withdrawal speed. UKGC-licensed brands typically process withdrawals within 1–3 working days once KYC is complete, and some open banking rails settle within hours. Offshore brands may advertise “instant payouts” and then apply a verification delay that adds two hours to the cashout before the payment queue even starts. The advertised speed and the actual speed are not the same metric.

Affordability Checks: The £150 Threshold and What It Means for Small Depositors

From 28 February 2025, UK-licensed operators must conduct financial vulnerability checks when a player’s net deposits exceed £150 in a rolling 30-day period. The threshold was lowered from £500 because the higher figure was catching harm too late. For a player depositing £5 or £10 at a time, £150 represents 15 to 30 deposits in a month — not an impossible total for a regular player, but a meaningful distance above the casual £5-a-week pattern.

The practical effect on the low-deposit tier is twofold. First, the £1 and £5 player is unlikely to trigger the check unless they are depositing frequently across multiple brands. Second, the check is triggered by net deposits, not gross deposits, for the FVC threshold — which is a different calculation from the gross deposit limit the player sets on their own account. The two mechanisms run in parallel. The player-set limit caps gross deposits; the operator-run FVC check looks at net deposits above £150. A player who deposits £200 and withdraws £100 has net deposits of £100 and does not trigger the check. A player who deposits £200 and withdraws nothing does.

Non-GamStop Casinos: What You Give Up

“Non-GamStop” is not a licence category. It is a marketing label for operators that do not participate in the GAMSTOP self-exclusion scheme. UKGC-licensed operators are required to participate, which means a brand advertising itself as “not on GamStop” is almost always offshore-licensed. The trade-off is straightforward: you gain access if you have self-excluded through GAMSTOP, and you lose UK dispute resolution, statutory levy protection and the segregated-funds framework that comes with a UKGC licence. A £5 deposit at a non-GamStop brand is still a £5 deposit. The difference is what happens when the withdrawal does not arrive.

Responsible Gambling Tools at the Low-Deposit Tier

Low deposit does not mean low risk. A £5 deposit player can lose £5 repeatedly, and the cumulative loss over a month can exceed a single £50 deposit that would have triggered a moment of reflection. The tools that mitigate that risk are standard across UKGC-licensed brands, and they are more useful at the low-deposit tier than the marketing suggests.

Deposit Limits, Reality Checks and Self-Exclusion

Every UKGC-licensed operator must prompt the customer to set a financial limit at registration or first deposit, and the limit-setting screen must be presented as the default choice — declining requires a deliberate action. Limits can be set for 24 hours, 7 days or one month, and where periods overlap the most restrictive limit applies. Reductions take effect immediately. Increases require a cooling-off period of at least 24 hours followed by a positive confirmation. That asymmetry is deliberate: the system makes it easy to tighten and hard to loosen.

Reality checks sit alongside deposit limits. The player chooses the frequency, the screen shows elapsed session time, and the message stays until acknowledged. Slot sessions display elapsed time throughout. Neither tool changes the house edge. What they change is the probability that a session extends beyond the player’s intended budget because the interface removed all friction from the next deposit.

The Gross vs Net Limit Distinction

The distinction between gross and net deposit limits is the most important piece of responsible gambling mechanics that low-deposit players routinely misunderstand. A gross limit caps total deposits regardless of withdrawals. A net limit subtracts withdrawals from deposits before applying the cap. The Commission clarified in October 2025 that the limits players set should be gross limits. That means a player who deposits £10, withdraws £20 and deposits another £10 has reached a £20 gross total, not a £0 net total. If the monthly limit was £15, the second deposit is blocked even though the player is ahead.

For a £5-a-week player, the gross limit is rarely a binding constraint. For a player who churns small deposits across multiple sessions, it is the mechanism that prevents the “I’m only putting in a fiver” pattern from becoming a £150 monthly total without a single conscious decision. The limit is not a punishment. It is a pre-commitment device that works only if it is set before the session, not after the third deposit.

Methodology: How This Page Was Built

This page is a working breakdown, not a leaderboard. The criteria were chosen to surface operators that a UK player can actually use at a £1, £5 or £10 entry point without losing access to the protections that come with a UKGC licence.

The Criteria

The brand must hold a current UKGC remote casino operating licence. The advertised minimum must be available on at least one mainstream payment rail without a promotional code. The bonus terms must be discoverable before deposit, including the wagering requirement, the maximum bet during wagering and any maximum cashout cap. The brand must offer player-set deposit limits and access to GAMSTOP. Offshore operators were excluded regardless of how low their advertised minimum was, because the loss of UK dispute resolution is a material cost that a low minimum does not offset.

What We Deliberately Left Out

We did not include brands whose £1 minimum applies only to a closed promotional window. We did not include brands whose minimum resets to £10 after the welcome offer. We did not include “no deposit bonus” offers that require a debit card for verification and cap withdrawals at £50, because those are verification funnels rather than low-deposit products. And we did not include any brand that could not produce a licence number on request. A low deposit is a small commitment. A missing licence is a large warning.

What is the lowest deposit casino in the UK?

The lowest genuine minimum at a UKGC-licensed operator is £1, typically on debit card deposits at bingo-led and slots-first brands such as Gala Bingo, Foxy Bingo and JackpotJoy. Some casino-first brands support £3 through open banking rails. The advertised £1 minimum usually applies to card only; PayPal and Paysafecard floors are higher.

Do £1 deposit casinos actually pay out?

Yes, if the operator holds a UKGC licence and the player completes identity verification. The £1 deposit is real money with full withdrawal rights once KYC is complete and any bonus wagering is cleared. The common friction is not non-payment but bonus terms: maximum cashout caps and wagering requirements can reduce the withdrawable amount well below the spin-win headline.

Can I deposit £5 at a UK casino without a bonus?

Yes. A minimum deposit is not a bonus trigger. You can deposit £5, decline the welcome offer and play with your own cash. The advantage is that any winnings are yours immediately, with no wagering requirement and no maximum bet cap. The disadvantage is that you forgo the spin bundle or match that the operator uses to acquire new players. For a player who intends to withdraw rather than recycle, the no-bonus route is often the cleaner option.

Are low deposit casinos safe?

A low deposit casino is as safe as its licence. UKGC-licensed brands must segregate player funds, contribute to the statutory levy and provide access to an ADR scheme. Offshore brands accepting UK players under Curaçao or Anjouan licences sit outside that framework and offer no UK dispute resolution route. The deposit amount does not change the licence requirement: a £1 deposit at a UKGC brand carries the same KYC and AML checks as a £300 deposit.

What payment method has the lowest minimum deposit?

Debit card generally has the lowest minimum, with some brands accepting £1. Open banking / Pay by Bank often sits at £3–£5, PayPal at £5–£10, and Paysafecard at £10. The method-specific minimum can be higher than the brand’s headline minimum, so check the payment page before registering.

Why do some UK casinos refuse deposits under £5?

Card processing economics. A debit card transaction carries a fixed authorisation cost plus a percentage fee, and on a £3 deposit the fixed element can consume a meaningful share of the operator’s margin before any game is played. Open banking changed the maths because the fee is flatter, which is why some brands can offer £3 on open banking while keeping a £5 card floor.
