£5 to £10: how the minimum changes by route
Minimum deposits by route: £5 on Boku, £10 on Siru Mobile
| Sites | Route | Minimum | Fee on top |
| A shrinking handful of sites, check the cashier | Boku | £5 where offered | none published by Boku; any casino surcharge varies |
| Videoslots, Mr Vegas, Mega Riches | Siru Mobile | £10 according to the operator | ~25–33% |
A "£10 minimum" Siru deposit is really £12.50+ once the surcharge lands on the bill, so minimums and fees have to be read together. At the £5 level, Boku is the only route, and Boku publishes no consumer fee, so any surcharge comes from the casino; the trade-off is that Boku is only listed at a shrinking number of sites.
£5 deposit casino means Boku only, usually no bonus, same legal caps
- A £5 deposit casino offers the lowest floor available: £5 via Boku sits under the £10 minimum most other routes use.
- No bonus at that level: most welcome offers ask for a £10+ qualifying deposit, so a £5 top-up is for testing a lobby, not chasing a match.
- The legal caps of £40 a payment and £240 a month still apply: a smaller deposit just uses less of them, it doesn’t raise the ceiling.
- Licensing can change, and has: the old £3, no-fee route belonged to In Touch Games Limited, whose UKGC licence was suspended in September 2023 over anti-money-laundering and fair-trading failures and then surrendered days later, and every brand built on it (mFortune, PocketWin, Mr Spin and others) closed. Any 2026 guide still quoting a live £3 deposit at those names is describing a dead operator; check a site’s current UKGC status before you deposit, whatever the minimum says.
Does a small deposit still qualify for a welcome offer? Usually only from £10
Most welcome offers require a qualifying deposit of £10 or more, so a £5 deposit usually does not qualify for a welcome offer. A £5 deposit suits testing a site first. If you do want the offer, check its minimum qualifying deposit and whether your billing route is an excluded method before depositing. 18+, T&Cs always apply.
£5 deposit by phone bill: same games and legal caps, fewer bonuses
A £5 deposit by phone bill is the lowest widely quoted minimum on UK-licensed sites, under the £10 Siru Mobile floor quoted by the operators. A £5 deposit buys the same games and counts against the same £240 monthly legal limit as any other deposit, and the main thing that changes is bonus eligibility, since most welcome offers ask for £10 or more. If you’re putting down £5 to try a lobby rather than chase an offer, that’s exactly what the amount is for.
Low deposit mobile casino quick reference, from £5 tests to £40 top-ups
| Deposit | What it suits | Bonus eligibility |
| £5 | Testing a lobby, strict small-stakes play (Boku only, where offered) | Rarely qualifies |
| £10 | The standard entry point across most routes | Usually qualifies, check the T&Cs |
| Up to £40 | The legal maximum for a single phone-bill payment | Full range of offers, where available |
A £10 deposit is the standard low-deposit entry point and usually qualifies for a welcome offer, while £5 rarely does. Ranked sites and full details: main pay by mobile casino list.
