What the licensed baseline is worth: protections priced one by one

Search for somewhere to play and the results split into two tiers that rarely label themselves. The first tier holds operators licensed by the Gambling Commission, which is the licensing authority for Great Britain and keeps a public register of every licensee, searchable by anyone in seconds. The second tier holds sites with no UK licence at all that nonetheless take British players, and a good share of the loudest bonus marketing comes from them. The law is clear about where the risk sits: providing facilities for gambling without an operating licence is an offence under section 33 of the Gambling Act 2005, and inviting or advertising prohibited gambling is a separate offence under section 327. Both offences sit with operators and advertisers. An individual player commits no offence by playing.

The licensed baseline is best described as a bundle, because that is what a licence is: a set of duties an operator owes every customer from the moment an account opens, enforceable in Britain rather than promised on a terms page. Licensees must make deposit limits, reality checks and account history available, and must register with an approved alternative dispute resolution provider, so a complaint has somewhere to go as of right. Their customers are covered by GAMSTOP, the free national online self-exclusion scheme, whose exclusions run a minimum of six months. They have been barred from taking credit cards since April 2020, and since September 2024 their online slots have been capped at £5 a spin for adults and £2 a spin for 18 to 24 year olds.

Each item in that bundle has a price once it is absent, and pricing by absence is the method this page uses throughout. The table below takes the protections that matter most to a person depositing their own money and states, on the right, what a reader carries instead when the account sits in the second tier.

Read only the right-hand column and the page’s thesis is visible without a single percentage. The costs are not abstract. They land on the night a deposit limit needs to hold and there is no scheme behind it; on the afternoon a withdrawal is withheld and the only inbox available belongs to the operator being complained about; on the evening a £10 spin looks reasonable because nothing in law has ever set a ceiling. A welcome bonus can be costed in turnover. A missing protection is costed in exactly these moments, and the rest of the page keeps returning to them, because they are the gap the title refers to.

What an online casino UK welcome package costs to clear

Start with the structure the licensed tier most commonly prints. A reader deposits £50. The operator matches it at 100 percent, so £50 of bonus funds lands beside the deposit and the pot stands at £100. The terms require the pot to be turned over a set number of times before anything becomes withdrawable, and the game weights decide which bets count towards that total. Slots usually count fully. Roulette and blackjack often count at 10 or 20 percent, and some live tables count for nothing. Everything the advertisement promises is filtered through three dials: the pot, the multiple and the weights.

The multiple needs one stated choice, and here it is: the arithmetic below takes forty times, since forty on the combined pot is the asking rate of the standard package across the licensed tier. On a £100 pot that means £4,000 of play before a withdrawal unlocks. Price that play at a blended 3 percent house edge, a fair middle for a slots-led session, and the expected cost is about £120. The match is worth £50 before any cap, so the realistic net sits near minus £70. A category-typical conversion cap of £250 never comes into play on numbers like these, which is worth noticing: on the standard licensed package the wagering alone does the damage, and the cap is a secondary risk.

The base deserves the same attention as the number in front of it. Forty times on the £50 bonus alone would demand £2,000; the same forty on the £100 pot demands £4,000. And the weights can multiply the bill again: clear a £4,000 requirement on a game weighted at 10 percent and the bets actually placed reach £40,000. That is why every realistic route through a wagering requirement is slots-led, and why the blended edge of the games a reader actually plays matters more than the percentage printed in the advert.

Time limits close the frame. Where an expiry applies, the model takes thirty days, because that is the span this part of the market typically allows. £4,000 of turnover inside thirty days is a daily quota of about £133, every day, for a month. That quota, not the headline, is what decides whether a package can be cleared by someone with a job, a commute and a week that does not rearrange itself around a bonus.

Welcome packages price volume over weeks. Single sessions price volume directly, and the calculator below does exactly that. It takes a bankroll, a stake per round, a house edge and a number of sessions, and returns the expected cost of the play. It is a costing tool, not a forecast: it does not know a good evening from a bad one, and it does not care how the last session went, because sessions have no memory of each other.

The note behind the numbers: the prefill sets a £100 bankroll, £1 stakes, a 2.7 percent house edge and ten sessions. The 2.7 percent is the European roulette rate, used as a neutral stand-in. Slots commonly run a wider edge than that and some table games run narrower, so the honest move is to change the input to match the game actually played; where a game publishes its return to player, subtract it from 100 and enter the remainder. On the prefill, £1 stakes at a 2.7 percent edge cost about 2.7 pence a round on average, so a thousand rounds across ten sessions cost about £27 of the £100 bankroll in expectation. That is the quiet rent the entertainment charges, and it scales with volume and nothing else.

The offshore gap: heavier multiples, thinner recourse

The second tier prints bigger numbers and charges for them in the same currency: turnover. Welcome matches run from 100 percent up to 500 percent, conversion caps reach £/€1,000 to £/€6,000, and the multiples sit in a band of twenty-five to sixty times, with the heaviest figures attached to the heaviest headlines. The pattern is not a coincidence. Doubling a match while doubling its multiple returns roughly the same expected value to the player while printing twice the number in the advert, so the headline can grow indefinitely without the offer becoming more generous. The multiple is where the generosity is quietly refunded.

Work one offshore structure against the baseline. Deposit £100, take a 200 percent match, and the pot stands at £300. The arithmetic below takes sixty times, since sixty is the top of the range the offshore tier’s own terms sheets print. That is £18,000 of turnover, against £4,000 on the standard licensed package from the section above. At the same blended 3 percent edge, the expected cost of clearing it is about £540, against about £120 at the baseline. The extra £150 of match money has purchased £420 of extra expected cost, before any cap, weight or expiry is applied. Run the same structure on a game weighted at 10 percent and the bets actually placed reach £180,000. The headline said 200 percent. The turnover says otherwise.

The money side of the gap is only half of it. Category-typical payout windows run zero to 48 hours at licensed casinos and zero to 72 hours offshore, and the paper gap widens in practice because only one of the two tiers has an enforceable clock. A licensed operator answers to an approved alternative dispute resolution provider and to the Commission, so a stalled withdrawal can be escalated as of right. Offshore, the escalation path ends at the operator’s own support inbox, and the operator is also the party whose terms decide the dispute. A window you can enforce and a window you can merely wait for are different products, whatever the hours printed beside them.

Protections resist this kind of arithmetic because they are not priced in pounds, so the model prices them by share instead. The chart below scores each protection category as a share of the UKGC baseline, where the baseline is 100 by definition. Three categories score full marks in law: the reach of self-exclusion, the availability of deposit limits and the existence of adjudication. The fourth bar is the blended score the model assigns the offshore equivalent, and the assumption behind it is printed with the chart rather than buried under it.

Read the amber bar as a modelled judgement rather than a measurement. Self-exclusion contributes nothing to it, because GAMSTOP covers only operators licensed by the Commission and cannot reach an offshore account at all. Deposit limits contribute only while the operator chooses to honour them, since no duty sits behind the tool. Adjudication contributes nothing, because no approved scheme exists. What remains, roughly a fifth, is the portion of ordinary play that never touches a protection: the deposits made on an ordinary evening for ordinary reasons. The figure is an assumption and an arguable one, which is precisely why it is printed beside the chart instead of hidden beneath it.

Tills and rails: how money moves at each kind of casino

Payment rails tell you which tier you are standing in before the terms do. The services that serve UK consumers include Visa, Mastercard, PayPal, Paysafecard, MuchBetter, Apple Pay, Google Pay, Skrill, Neteller and Trustly, and whether any given operator accepts them varies by operator and changes over time. Everything in this section is therefore category-typical: a description of how each kind of till tends to look, never a promise about a single cashier and never a substitute for reading the cashier’s own page before funding it.

Licensed tills cluster around a short list: Visa and Mastercard debit cards, PayPal at many casinos, plain bank transfer beneath them, and Apple Pay increasingly common at bingo-led brands. Offshore tills lean differently. Crypto is common and often leads, e-wallets such as MuchBetter appear frequently, and the familiar UK e-wallets appear unevenly or not at all. The lead rail is a fact about the operator long before the terms are, which is why the rails column sits in the comparison table directly beside the licence label rather than buried at the end of the row.

The credit card line deserves its own paragraph. Credit card gambling has been banned for GB-licensed operators since April 2020, and the ban exists because borrowing to gamble behaves differently from spending to gamble. Operators with no UK licence may still accept credit cards, and some do. A till that offers the option is publishing a fact about itself, and the option matters independently of any bonus: funding play on a card means paying card rates of interest on money that is already expected, on average, to fall to the house edge.

Four checks make any till legible in a couple of minutes. First, currency: what does the till charge in, and what does conversion cost if your bank bills in pounds? Second, minimums: does the deposit minimum match the minimum the welcome terms actually demand, since the two are not always the same number? Third, withdrawal rails: does the rail that takes deposits also carry withdrawals, or does the till take money one way and pay it back another? Fourth, exclusions: some tills disqualify welcome offers on certain e-wallets, a rule printed only in the terms. Check all four before the first deposit, because afterwards none of them is a negotiation.

Rails also explain part of the payout window story. A withdrawal to a fast e-wallet can settle within hours once approved, while a bank transfer waits on clearing cycles no operator controls. Crypto adds its own rhythm at offshore tills: network confirmation replaces banking hours, often quick in theory and less predictable at busy periods. When a window is quoted anywhere, the useful question is which rail the quote assumes, because the approval and the journey are two separate delays and only one of them is visible at the till.

The comparison table: baseline rows against offshore rows

The table below sets rows from both tiers side by side, in the same columns a reader will meet at any cashier: licence, welcome range, wagering, minimum deposit, payout window and rails. The licence column is the one that outranks the rest. The ranges are category-typical, compiled from operator-published terms at the time of writing, and the UKGC rows are printed as the baseline against which the offshore rows should be read, not as promotions to chase.

Figures are category-typical ranges compiled from operator-published terms at the time of writing. They are not quotes of any single promotion. UKGC rows are the British baseline, shown for comparison; none of them are claimable at offshore offers.

Two cautions travel with the table. First, ranges move: terms are rewritten, caps change and a cashier can sit outside its band in either direction, so the table describes categories rather than contracts. Second, the rows reward reading that ignores the vertical. The bingo-led row carries a multiple of 2x to 4x, the lightest arithmetic on the page, while the offshore rows carry multiples of 25x to 60x against far bigger caps; the vertical does not decide the bill, the structure does. Read the licence column first, the wagering column second and the welcome column last, and the table will not mislead.
