Can You Stop Someone Else Gambling?
It’s one of the most painful searches anyone types into Google: how do I stop my partner, my friend, my relative from gambling? The honest answer is that Britain’s protection tools are built around the gambler’s own consent, and you can’t switch them on for someone else. But that doesn’t mean you’re powerless to help someone who’s struggling.

Most of the messages that reach this site come from players. Some of the hardest ones to read don’t. They come from a wife who’s found the bank statements, a father whose twenty-year-old keeps borrowing money she can’t explain, a son who’s just realised why his dad’s pension disappears every month. Almost all of them ask a version of the same question: is there a button I can press to stop this?
They’re far from alone. The Gambling Commission’s own survey work suggests nearly one in eleven adults in Britain was harmed by someone else’s gambling in 2024, through stress, broken trust, money vanishing and relationships buckling. Yet only around one in seven of those people sought any help at all. That gap, between how many people are carrying this burden and how few know where to put it down, is the reason this article exists.
Why every lock is on the inside
Let me get the hard part out of the way first, because you’ll find out anyway. GAMSTOP, the national online self-exclusion scheme, only accepts registrations from the person being excluded. The same goes for the land-based schemes covering betting shops, casinos, bingo halls and arcades, and for exclusion directly with an operator. Bank gambling blocks are attached only to the account holder’s own card. And every one of these schemes is confidential: none of them will confirm to a family member that someone has registered, or that they haven’t.
When you’re watching someone you love lose control, that design feels cruel. However, it’s the right one. A system that let one adult switch off another adult’s gambling, or their access to their own money, would be exploited almost immediately in controlling relationships, and the people least able to challenge a false exclusion would be the ones most likely to suffer it. Consent is the lock that keeps these tools from becoming weapons. The painful consequence is that the decision to use them belongs to the gambler, and your job becomes making that decision more likely, safer and less lonely, rather than making it for them.
The levers you actually hold
That said, you’re far from powerless. There are four possible levers, and most families only ever find one of them.
Lever one: tell the operator
An operator won’t discuss someone’s account with you, and data protection law means it can’t. But UK-licensed operators are required to use all the information available to them about a customer when deciding whether that person is at risk of harm, and a concern from a family member is information. Write to the operator’s safer gambling or customer service team with specifics: the person’s name and any details you know, what you’ve seen, the financial impact, anything they’ve said about chasing losses or borrowing. You won’t hear what happens next. That’s frustrating, but it doesn’t mean nothing happens, and a well-documented concern is far harder to overlook than a vague one.
Lever two is your own money, and it’s the one I’d use first, because it’s the only one entirely in your hands. If you share finances with someone whose gambling is out of control, protect the parts that are yours. Open an account in your own name for your income. Change the PINs and passwords they might know. Stop lending, and think carefully before paying off gambling debts, because bailouts often fund the next round rather than end it. If you have joint credit, a joint loan or a joint account, it can link your credit file to theirs, and once your finances are separated, you can ask each of the credit reference agencies to record a notice of disassociation so their borrowing stops affecting your score. Banks also have specialist support teams for customers in vulnerable financial situations, and it’s worth asking yours what it can do for you specifically.
Lever three is the toolkit itself, offered rather than imposed. Device-blocking software, bank gambling blocks and GAMSTOP all take a few minutes to set up, and some people find it far easier to do that with someone sitting beside them than alone at midnight. Offering to help is support. Installing blocking software secretly on another adult’s phone, or logging into their accounts, crosses into territory that can damage trust badly and, depending on the circumstances, may cross legal lines too. Children are different: if someone under 18 is gambling, they shouldn’t be able to on a licensed site at all; parental controls are entirely appropriate, and the operator should be told straight away.
Lever four is the conversation, and it’s the one that matters most. People rarely stop because they’ve been caught or shouted at; shame tends to drive gambling underground rather than end it. What helps is choosing a calm moment, talking about specific things you’ve seen and how they’ve affected you, and being clear about what you will and won’t do from now on. You can’t make someone want help. You can make the door to it very easy to find.
Where help becomes control
This needs saying carefully, because it cuts both ways. Taking control of another adult’s money without their agreement, monitoring their accounts behind their back or restricting their access to their own income can amount to economic abuse, which UK law recognises as a form of domestic abuse. Most families in this situation are acting out of love and fear, and I’m not suggesting otherwise. But the line exists, and staying on the right side of it protects everyone, including you.
The reverse is just as true. If someone’s gambling has them draining shared money, taking out credit in your name, pressuring you for cash or lying to keep you from seeing the accounts, that can be economic abuse against you. You’re allowed to say it, and you’re entitled to help with it.
If anything in that paragraph lands close to home, domestic abuse services handle financial control as well as other forms of abuse, and you don’t need to be in physical danger to use them. Protecting yourself isn’t abandoning the person who gambles. Often, it’s the very thing that changes the situation.
Help that’s for you, not just for them
Here’s the bit most affected people skip, and shouldn’t. You’re allowed support in your own right, whether or not the person who gambles ever accepts any. The National Gambling Helpline, run by GamCare on 0808 8020 133, talks to family members and friends as well as gamblers, any day of the week. Gam-Anon runs peer support groups specifically for people affected by someone else’s gambling. Some NHS gambling clinics offer support for family members too, and if you’ve been bereaved through gambling, the charity Gambling with Lives was set up by families who’ve been through it. If you’re struggling to cope right now, Samaritans are there on 116 123, day or night.
A short checklist for this week
✓ Move your own income into an account only you control, and change any shared PINs or passwords.
✓ Write down what you’ve seen, with dates and amounts, so any concern you raise is specific.
✓ Contact the operators you know about, in writing, and set out your concerns clearly.
✓ Look up the self-exclusion and blocking tools so you can offer to help set them up when the moment comes.
✓ Make one call for yourself, whether that’s the helpline, a peer group or someone you trust.
If the person you’re worried about self-excludes and an operator lets them gamble anyway, that’s a serious failure, and refunds of deposits made during the exclusion period are a real possibility. My piece on recovering gambling losses explains how those claims work. It’s one of the few situations where the system’s mistakes can be put right after the fact, which is another reason helping someone register is worth so much.
Should the law go further?
I’ve thought about this a lot, and I don’t think there’s an easy answer. There’s a reasonable case for a carefully guarded family route into exclusion for the most severe cases, with independent checks and a clear way for the gambler to challenge it, and the scale of harm to affected others makes the question worth asking out loud. But every safeguard that makes such a scheme safe from abuse also makes it slower and harder to use in exactly the crisis moments families are desperate about. Until someone designs that balance convincingly, the most useful reforms are probably the smaller ones: better-funded support for affected others, operators acting faster on family concerns, and banks building more tools that let customers bring a trusted person into their own protections voluntarily.
Can you stop someone else gambling? Not directly, and not on their behalf, because every serious tool in Britain is designed to require their consent, for reasons that are painful but sound. What you can do is narrower and more powerful than it first looks: make sure operators know what you know, put a wall around your own money and credit, keep the door to help wide open and easy to walk through, and refuse to carry all of this on your own. The person who gambles has to make their own choice. You’re allowed to make yours too, starting with a phone call that’s entirely about you.
