The first security move after a lottery win is usually saying less
Winning does not suddenly make every stranger dangerous. What changes first is that information about you may become more valuable. The fewer people who know while you are still working things out, the more choices you keep.
Keep the circle small
You can tell more people later. You cannot easily pull the news back once it has travelled through family, work or social media.
Do not post clues
A screenshot, celebration photo, location tag or “something amazing happened” post can start questions before you are ready.
Secure the important accounts
Email, banking, phone and messaging accounts deserve strong passwords or passkeys and two-step verification.
Give yourself time
You do not need a full security overhaul tonight. Deal with the easy high-value changes first and assess what is genuinely needed.
Do not measure your security by the size of the jackpot
The right level of security depends on your circumstances, not simply the size of the win. A private winner who keeps a low profile may need little beyond sensible home, digital and privacy measures. A winner who becomes publicly known or receives unwanted attention may need to take additional precautions. The aim is to match security to your real level of exposure and risk.
Who knows about the win — and who really needs to?
For most winners, this is where security actually starts. One person knowing can become ten remarkably quickly, not because everybody is malicious but because extraordinary news is hard to keep contained.
Should You Stay Anonymous?
Work through the genuine benefits and trade-offs of keeping your identity out of publicity.

Going public is not automatically a mistake. Some winners enjoy celebrating openly and would rather not invent explanations for a suddenly different life. But publicity is a one-way privacy decision: once your name, face, town and jackpot are widely known, it is very difficult to become anonymous again.
The exposure ladder
What has happened to real public winners?
Jane Park — £1m
Park, who won at 17, later said her main regret was going so public with the win. Her experience is an unusually stark reminder that publicity can outlast the excitement of the announcement.
Read the ITV interview →Roger Robar — £5.8m
After becoming well known locally, Robar described being overwhelmed by requests for money, including people turning up at his door. He eventually said the constant begging was a reason he planned to leave Britain.

Your email account may matter more than your front gate
Email, phone numbers and social accounts can connect to banking, password resets, identity documents and people you know. The NCSC recommends strong unique passwords, two-step verification and careful control of what personal information is available online.
Do these first
- Use a strong unique password or passkey on important accounts.
- Turn on two-step verification for email, banking, messaging and social accounts.
- Update phones, computers and apps.
- Review account recovery email addresses and phone numbers.
- Review social-media privacy settings and old public posts.
Be suspicious of these
- Unexpected login or 2SV approval requests.
- Anyone asking for a verification code.
- Links sent by a caller who says they are from your bank.
- New “advisers” or investment opportunities that arrive without being requested.
- Urgency designed to stop you checking who the person really is.
Digital Security After Winning
Email, phones, banking, social media, SIM swaps and protecting accounts from targeted attacks.

Read the scam guide →Good physical security should make life calmer, not stranger
Official ProtectUK guidance starts with ordinary layers: sensible home routines, doors and windows, awareness of unusual activity, appropriate perimeter security and measures that fit the real circumstances. That is a better starting point than immediately turning a home into a fortress.
Do the basics well
Doors, windows, locks, lighting, alarms and cameras should work properly before you start looking at exotic security products.
Think about visibility
A highly visible new home, expensive deliveries or sudden building work can tell neighbours more than you intended.
Keep children out of the security job
Give age-appropriate information. Children should not feel responsible for protecting a secret worth millions.
Do not publish routines
School, holidays, empty properties and regular locations do not need to be announced in real time online.
Physical Security After Winning
Home, routines, travel and when professional security might genuinely be justified.

Moving can be a lifestyle decision, a privacy decision or both — but it is not automatically a security requirement.
Read the moving guide →The most convincing scam may know quite a lot about you
The NCSC warns that criminals use information available online to make phishing and impersonation more believable. Wealth can make a person a more interesting target, but the defence is still wonderfully boring: slow down, verify independently and never hand over access codes.
“Your bank is calling”
Hang up and contact the bank using a number you already trust. Do not rely on the caller ID or a number the caller gives you.
“I have an opportunity for you”
Winning money can attract unsolicited investment, business and charity pitches. There is almost never a reason to decide immediately.
“Read me the code”
Verification codes are there to prove access. Do not give them to somebody just because they sound official.
What if attention turns into harassment, blackmail or a real threat?
Most lottery winners will never need specialist protective security. But persistent unwanted contact, stalking, blackmail, threats or attempts to gain leverage are different from ordinary curiosity and should be treated accordingly.
Keep the evidence
Save messages, emails, usernames, numbers and dates rather than deleting everything in the hope it disappears.
Do not let the other person set the pace
Threats often depend on urgency and fear. Avoid making payments or promises simply to buy temporary silence.
Bring in the right help
Police, legal advice and appropriately qualified security specialists become relevant when the issue moves beyond ordinary privacy management.

ProtectUK Blue Book →Lottery winner security and privacy FAQs
Plain-English answers about anonymity, phones, social media, homes, children, scams and when security genuinely needs to become more serious.
What should a lottery winner do first to protect their privacy?
Tell as few people as possible until the win is verified and you understand the claim process. You can always widen the circle later; it is much harder to make widely shared news private again.
Can UK National Lottery winners remain anonymous?
Yes. The National Lottery says winners can remain anonymous and publicity is their choice. That does not mean privacy looks after itself: family, work, neighbours and social media can still reveal more than you intended.
Should you keep a lottery win secret?
Keeping the circle small at first can buy useful thinking time. Whether you stay private long term is a personal choice, but there is rarely a benefit in telling lots of people before the claim and your plans are settled.
Who should you tell after winning the lottery?
Usually only people who genuinely need to know at first: perhaps a partner or one trusted person, plus the official claim team. Wider family, friends, colleagues and social media can wait.
Should you post a lottery win on social media?
Not in the early rush. Even a vague celebration, screenshot, location tag or expensive-purchase post can reveal more than you think and can be copied or shared after you delete it.
Do lottery winners need bodyguards?
Usually not. Official UK personal-security guidance says protection should match the actual threat and your vulnerabilities. Better privacy, sensible home security and strong digital security are far more relevant for most people.
Does a bigger lottery win automatically mean higher security risk?
Not by itself. A very private £20 million winner may be less exposed than a highly public £2 million winner. Publicity, location, routines, family circumstances and any specific targeting matter more than a simple jackpot threshold.
Should a lottery winner move house for security?
Not automatically. Moving can improve privacy in some circumstances, but it can also make the win more visible. Think about the existing property, neighbourhood, access, family routine and whether there is a real reason to move.
What home security should a lottery winner consider?
Start with ordinary layers done well: secure doors and windows, good locks, lighting, alarms or cameras where useful, controlled access and awareness of unusual activity. Security should fit the property and actual risk rather than turn home into a fortress.
How should lottery winners protect their phones and email?
Use strong unique passwords or passkeys where available, turn on two-step verification, keep devices updated and treat the email account linked to banking and important services as a high-value account.
Is SMS two-factor authentication enough?
It is better than no second factor, but stronger options may be available. The NCSC notes that authentication apps and phishing-resistant methods can provide better protection in higher-risk situations.
What is a SIM-swap attack?
It is when an attacker tries to take control of your mobile number, which can help them intercept calls or SMS codes. Strong account security and using authentication methods that do not rely only on SMS can reduce the risk.
How can lottery winners avoid scams?
Slow the conversation down. Do not trust an approach just because the caller knows personal information. Never share passwords or verification codes, and contact banks or organisations using details you already know are genuine rather than links or numbers supplied in a suspicious message.
What should I do if I receive a suspicious email or text?
Do not click links or open unexpected attachments. The NCSC provides routes for reporting suspicious emails, texts and websites. If you have shared bank details or lost money, contact your bank immediately and use the current official fraud-reporting route.
What if I have already given a scammer my password?
Change it immediately anywhere it was reused, secure the affected account and review recent activity. If banking details or money are involved, contact the bank straight away.
Should children know about a lottery win?
That depends on age and family circumstances. Children do not necessarily need the exact figure immediately, especially if knowing it makes privacy harder. The aim should be age-appropriate honesty without making them responsible for protecting an adult secret.
How can a lottery winner protect children without frightening them?
Keep routines as normal as practical, avoid giving children unnecessary detail, review what the family shares online and make changes quietly. Security should make family life calmer, not make children feel they are in danger.
Should a lottery winner change phone numbers and email addresses?
Not automatically, but separating important private contact details from public or old accounts can be useful if exposure increases. The priority is securing the accounts you already use before creating a complicated new system.
When should a lottery winner speak to a security professional?
When there is a specific threat, unwanted attention, a highly exposed property or routine, substantial publicity, stalking or harassment, or when you genuinely cannot judge what level of protection is appropriate. Use properly qualified professionals rather than buying fear-driven security packages.
What should you do about blackmail or threats after winning?
Do not handle serious threats alone or pay simply to make the problem disappear. Preserve evidence, stop unnecessary engagement and seek appropriate police, legal and specialist advice. Immediate danger should be treated as an emergency.
What is the biggest privacy mistake after winning the lottery?
Losing control of the information too early. A public announcement, group chat or careless social post can create attention before you have decided how you want the win to affect your life.
Is lottery winner security mainly about physical safety?
No. For most winners the first issues are information and digital security: who knows, what is online, how accounts are protected and whether scammers can build a convincing picture of the household.
What should I read first if I have actually won?
Start with the First 48 Hours guide and Winner Checklist. Once the immediate claim and privacy decisions are under control, use this hub to go deeper into anonymity, digital security, scams, home safety and family privacy.
Do lottery winners ever regret going public?
Yes, some have. Jane Park, who won £1 million at 17, later said her main regret was going so public with the win. Other public winners have described persistent requests for money and unwanted attention. That does not mean publicity is always a mistake, but it is worth treating the decision as difficult to reverse.
