The minimum deposit is the smallest amount a casino will accept to open an account with real money. It sounds like a minor detail, and it is the kind of thing that gets buried under the headline bonus. But it decides two things that matter: how much you have to commit before you can try a site at all, and whether you can actually claim the welcome offer you came for.
There is a reason the two are connected. A welcome bonus is almost always tied to a minimum deposit — deposit less and the bonus does not apply. So a casino advertising a large percentage on a small minimum is offering a low entry point, while one with a high minimum is, in practice, asking you to stake more before the offer switches on. This page sets out where the casinos we compare sit, and what the number actually costs you.
Where the ten casinos we compare sit. Every one of them has a minimum deposit of £20. None goes lower, and none of the published offers can be claimed for less. That is the honest finding: on this site, the minimum deposit is not a way to separate the casinos — they are all the same — so the useful question becomes what that £20 buys you at each one.

The minimum deposit is a floor set by the operator. It is the smallest amount its payment processor and its terms will accept. It is not a limit on how much you can deposit over time, and it is not the same as the minimum withdrawal, which is often a different figure and is sometimes higher.
Two things are worth separating here. The minimum deposit is what you must put in to fund the account. The minimum to claim the bonus is a separate condition in the promotion terms, and the two do not always match — a casino can accept a smaller deposit than it requires for the welcome offer. Where that happens, you can fund the account for less, but you will not trigger the bonus until you reach the promotional minimum.
A low minimum deposit is not automatically player-friendly. A casino that accepts a small deposit but ties its bonus to a much larger one is using the low figure as an advert, not as a genuine entry point. The number that matters is the one in the bonus terms, not the one on the cashier page.
Minimum deposits in the wider online casino market cluster into rough tiers. The casinos we compare all sit in the same one, but it is worth knowing the range because it explains why some sites advertise a £5 or £10 entry point and others do not.
| Tier | Typical minimum | What it usually signals |
|---|---|---|
| Low | £5 – £10 | Common at UK-licensed sites, where card deposits are cheap to process and the operator wants to lower the barrier. Rare at offshore casinos. |
| Standard | £10 – £20 | Where the casinos we compare sit. High enough to cover processing costs, low enough to be a reasonable first deposit. |
| High | £20 – £50 | Usually a sign of a smaller operator, or one using the minimum to push players toward a larger first deposit. |
The reason offshore casinos tend to sit at the standard tier rather than the low one comes back to the same theme as everything else on this site: the licence. Card processing for gambling merchants is more expensive and more restricted for an operator without a UK licence, so the economics push the minimum up. A £5 minimum is a UK-licensed convenience more than an offshore one.
This is where the number stops being trivia. Welcome bonuses in this market are almost always percentage matches on a deposit, with a stated minimum. The bonus codes the casinos in our comparison publish all require around £20 or €20 — the same figure as the minimum deposit, which is why the two tend to be quoted together.
A worked example makes the trade-off clear. A 400% match on a £20 deposit produces an £80 bonus. The same 400% on a £200 deposit produces £800 — a much larger number, but also a much larger amount of your own money committed, and (because wagering is applied to the bonus) a proportionally larger clearing requirement. The minimum deposit is not just the entry point; it is the smallest version of the decision.
A percentage bonus on a minimum deposit is the cheapest way to test a casino. The bonus is small, so the wagering attached to it is small too, and you find out how the site handles registration, verification and support before committing a larger amount. That is a legitimate reason to start at the minimum rather than above it.
A common question is whether depositing the minimum is worth it at all, given how small the resulting bonus is. The answer depends on what you are trying to do.
Where a casino accepts GBP as an account currency — as all the ones we list do — the minimum deposit is genuinely £20, not £20 converted from euros with a spread on top. That is worth checking at any casino, because a minimum quoted in euros and charged in pounds is quietly more expensive than it looks.
Four things, in order, all of them published in the terms rather than hidden:
Every casino we list publishes a £20 minimum and accepts GBP. Where the details differ is in the bonus terms attached to that £20, and that is the part worth reading. The full comparison sets out each casino’s offer on the same criteria, and the individual reviews go through the terms in full.
All ten accept a £20 minimum deposit. Each has a full review setting out its terms.
All ten casinos we compare have a minimum deposit of £20. None of them accepts less, and none of the published welcome offers can be claimed for a smaller amount.
Not automatically. A low minimum lowers the barrier to trying a site, but it often comes with a bonus tied to a larger deposit, so the low figure is an advert rather than a genuine entry point. The number that matters is the minimum stated in the bonus terms.
Usually yes, if the bonus minimum matches the deposit minimum — which, at the casinos we list, it does. But the bonus will be small, because it is a percentage of what you deposit, and the headline figure in the advert assumes a much larger deposit.
No, and it is worth checking separately. The minimum withdrawal is often a different figure, and a withdrawal floor higher than your deposit can leave a small balance you cannot get out. It is stated in the terms.
Mainly processing economics. Card payments for gambling are more expensive and more restricted for an operator without a UK licence, so the cost of handling a very small deposit is harder to cover. A £5 minimum is largely a UK-licensed convenience.
Not directly, but check the minimum withdrawal before you deposit. If it is higher than your balance after play, you may need to deposit more or play further before you can withdraw. The terms state the figure.
