GamStop and blocking software like Gamban solve two different problems, so "which one" is the wrong question. GamStop is Great Britain's free national self-exclusion scheme, and it works at the account layer: register once and every operator licensed to offer online gambling in GB must close your accounts, return any money in them, refuse new sign-ups, and remove you from marketing databases. Blocking software (Gamban, BetBlocker, GamBlock) works at the device layer: it stops your phone, tablet, or laptop from loading gambling sites and apps at all, including the offshore sites GamStop cannot touch.

The safest setup is not one or the other but both, plus a gambling block at your bank: three layers, each catching what the others miss. This is not just a slogan. An independent evaluation by Kantar, published in June 2026, studied people who combined support, self-exclusion, and blocking software, and found the combination beat any single tool; 68% said using more than one element made it much easier to cut down.

What GamStop blocks, and what it can't

GamStop covers every gambling company licensed to operate online in Great Britain. That is not voluntary: participation has been a condition of a UK Gambling Commission license since March 31, 2020. Registration is free, takes a few minutes, and is widely used: 614,738 people had signed up by mid-2026, with registrations up 16% year on year and a record 12,236 people joining in May 2026 alone.

Three details on the sign-up form matter more than anything else. You choose a minimum exclusion of six months, one year, or five years (or five years with auto-renewal); about half of all registrants pick five years. When that minimum period ends, nothing reopens: under GamStop's terms, your exclusion continues for up to seven more years unless you contact the scheme and ask to be removed. And removal is never instant. There is a cooling-off of at least 24 hours after you ask, during which the exclusion stays active, so a single 2 a.m. impulse can never undo the whole thing.

The limits are just as concrete. GamStop's own terms say it is "unable to help prevent you from accessing gambling services that are operated by organisations which do not participate", which in plain language means offshore and unlicensed casinos, crypto gambling sites, and anything licensed outside Great Britain. An entire marketing industry lives in this gap: search anything GamStop-related and you'll see "casinos not on GamStop" promoted at the top. Those sites target self-excluded people deliberately and sit outside UK consumer protections. GamStop also does nothing on your device (the sites still load; only your accounts are blocked) and does not cover in-person gambling. Betting shops have a separate free scheme, GamStop Betting Shops, formerly known as MOSES.

What blocking software does differently

Blocking software never asks who licensed a site. It sits on your device and refuses to load gambling content, whether the operator is regulated in Britain, Curaçao, or nowhere. That makes it the only tool in this comparison that closes the offshore gap.

Three established options, with prices as of September 2026:

The honest caveat: a blocker protects only the devices it is installed on. A new phone, a borrowed laptop, or a workplace computer is unprotected, and a determined person can eventually work around most software. That is not a reason to skip it; it is the reason it pairs with an account-layer tool that follows you everywhere. Our comparison of gambling-blocking apps for iOS and Android covers setup details and which tools survive uninstall attempts.

The layer both of them miss: your money

Neither tool stops money from moving. If an offshore site loads on a friend's phone, the only thing left between an urge and a deposit is your card, which is why a bank gambling block is the standard third layer. It works on merchant codes: the bank recognizes a transaction as gambling and declines it. The UK Gambling Commission lists over a dozen banks that offer one, including Barclays, HSBC, Lloyds, Monzo, NatWest, Santander, and Starling; you'll usually find it in the app under card settings. Monzo's version, for example, makes you pick a cooldown of 2 days to 1 year when you switch it on, and the block cannot come off until that cooldown ends.

Bank blocks are imperfect too. They generally apply to card payments only, so bank transfers and some e-wallet routes can slip through, and a merchant miscoded as something other than gambling won't be caught. Perfection isn't the point, though. Every layer adds seconds and steps between impulse and bet, and urges are time-limited; slowing a relapse down by a few minutes is often enough for it not to happen. That is the same logic as riding out an urge instead of acting on it.

A layered setup you can finish in about 30 minutes

  1. Register with GamStop (a few minutes, free), or your country's national scheme. Choose five years unless you have a strong reason not to; half of registrants do, and the decision only has to be made once.
  2. Install a blocker on every device you own (10–15 minutes). BetBlocker if money is tight; Gamban's 7-day trial if you want to compare. Skipping a device defeats the purpose, because the urge will find the unprotected screen.
  3. Switch on your bank's gambling block (2 minutes in the app), with the longest cooldown offered.
  4. Tell one person what you've done. The clearest finding of the Kantar evaluation was that tools work best alongside human support: 54% of people strongly agreed that practical tools plus support changed their behavior. A helpline counts; in the UK that's GamCare's National Gambling Helpline.

If you only have ten minutes right now, do step 1 tonight and the rest tomorrow. The order matters less than getting the first layer up, and every layer you add moves the work from willpower to infrastructure.

Outside the UK: national schemes plus universal blockers

GamStop is GB-only, but the account layer exists in most regulated markets. Sweden's Spelpaus has run a national register covering all licensed operators, online and land-based, since 2019; Denmark has ROFUS, the Netherlands has Cruks, and Germany has OASIS. Coverage, durations, and sign-up steps differ, and we keep a full breakdown in our guide to gambling self-exclusion by country. The device layer, meanwhile, is universal: BetBlocker, Gamban, and GamBlock work the same wherever you live, which makes a blocker the fastest first step in countries with no national register at all. The layering logic doesn't change — block your accounts where a scheme exists, block your devices everywhere, and block the money at your bank if it offers it.
