What to do if…
someone is shining a light into your home from outside at night
Short answer
Treat it as a possible incident in progress: get away from windows, secure your home, and contact police (999 if you feel in immediate danger, otherwise 101).
Do not do these things
- Do not go outside to confront them or “see what’s going on”.
- Do not stand in a lit window or open the curtains wide to look.
- Do not dismiss it if the light is scanning rooms/doors/windows or you feel unsafe—act cautiously first.
- Do not shout threats, chase them, or try to detain anyone.
- Do not post live updates on social media (it can reveal you’re home and where you are inside).
What to do now
- Move to a safer position. Step back from windows and glass doors. If you can, go to a more internal room and stay out of sight.
- Secure the house quickly and quietly. Lock external doors, check ground-floor windows are shut/locked, and close curtains/blinds.
- Get essentials in your hands. Take your phone and keys. If you have an alarm, arm it.
- Use lighting carefully (only if it doesn’t expose you). If you can switch on a porch/security light from a safe spot, it may discourage someone. Avoid going near windows/doors and avoid backlighting yourself in a window.
- Check without putting yourself in view. If you have a doorbell camera/CCTV, check the live view or recent clips. If it’s safe, note the time, where the light is coming from, and any description (clothing, direction of travel, vehicle). If you can discreetly record from inside without revealing yourself, do so.
- Call the police.
- Call 999 if you believe someone is trying to get in, is in your garden, is threatening you, or you feel in immediate danger.
- Call 101 if the person/light has gone but it was suspicious and you want advice and a record.
- If you can’t speak safely: call 999 anyway. If you can, respond by coughing/tapping/whispering. If you’re on a mobile and you hear a prompt, press 55 to confirm it’s a genuine emergency and be put through to police.
- If you’re in a flat or managed building: contact the concierge/security (if you have one) while someone else calls the police, and avoid using communal areas until you know it’s safe.
- If you’re not alone: quietly wake others, keep everyone together, and have one person speak to police so information is consistent.
What can wait
- You do not need to decide right now whether it was a prank, a neighbour, or targeted harassment.
- You do not need to go outside to “check for damage” until you feel safe and, if needed, police have attended.
- If it turns out to be ongoing nuisance lighting from nearby premises (not an immediate threat), you can deal with it later via your local council (often the environmental health team) as a potential statutory nuisance issue.
Important reassurance
It’s normal to feel frozen or shaky in this situation. You’re not overreacting by prioritising safety and contacting police if you feel at risk. The goal tonight is to reduce visibility, secure your home, and get help if needed.
Scope note
This is first-steps-only guidance for the next few minutes. If it becomes a repeat pattern, you may need follow-up support (for example around harassment/anti-social behaviour or nuisance lighting), but that can wait until you’re safe.
Important note
This is general information, not legal advice. If you think you are in immediate danger or a crime is happening, call emergency services.
