What to do if…
you return home and your interior lights or curtains are in a different position than you left them
Short answer
Stay outside and treat it as a possible break-in. Move to a safer spot nearby and call 999 if you think someone may be inside, the crime may be in progress, or you feel in immediate danger; otherwise call 101 (or report online).
Do not do these things
- Do not go in “just to check” or call out into the property.
- Do not confront anyone you see, or try to block exits.
- Do not start touching, tidying, or moving things “back to normal”.
- Do not go searching room-to-room, including sheds/garages/outbuildings.
- Do not post about it on social media or message widely with your exact address.
What to do now
- Pause at a safer distance. Step away from the door (and any ground-floor windows). If you can, go to a neighbour, nearby shop, or sit in a locked car where you can still see the entrance from a safer distance.
- Scan from where you are (don’t approach). Look for anything obviously wrong (door not fully shut, damaged frame, open window, unfamiliar person/vehicle nearby, movement inside). Don’t go closer to “inspect”.
- Call the police.
- Call 999 if you think someone may still be inside, you feel threatened, or you believe the crime may be in progress.
- Call 101 if you’re outside and safe and it seems like whoever did it is gone, but you still suspect unlawful entry (you can also report non-emergencies online). Tell them: your address, what changed (lights/curtains), whether anyone with permission could be inside, and any suspicious person/vehicle you noticed.
- If you can’t speak safely on a 999 call, use the silent-call process. Call 999 and listen to the operator’s questions.
- If you can, cough or tap the handset/keys to answer.
- On a mobile, if prompted, press 55 to confirm it’s a genuine emergency and be put through to police.
- On a landline, staying on the line (with background noise) can lead to the call being transferred to police.
- Wait for police guidance before entering. If officers attend, ask them to confirm when it’s safe to go back in. If you have a monitored alarm, you can tell the monitoring service you are outside and police have been called.
- Keep support simple. Contact one trusted person to stay on the phone with you or wait nearby, so you’re not alone outside.
- Once you’re told it’s safe to enter, change as little as possible at first. Take a few photos of anything disturbed before you touch it. Avoid handling door/window areas that might have been used.
- Write down the essentials while it’s fresh. Note what seems different, any missing keys, and any missing high-risk items (car keys, ID, bank cards). Ask for the crime reference number if a report is taken.
What can wait
- You do not need to decide right now whether it “definitely was” a break-in.
- You do not need to do a full inventory immediately; safety and reporting come first.
- You do not need to arrange new locks or repairs until the property is confirmed safe and you’ve documented what you can.
- You do not need to contact insurers while you’re still shaken; you can do that after you have a crime reference number and a clearer picture.
- You do not need to plan long-term security upgrades tonight.
Important reassurance
A sudden sense that something is “off” at home can trigger a strong fear response. Staying outside and getting help first is a sensible, protective choice, even if there later turns out to be an innocent explanation.
Scope note
These are first steps to keep you safe and avoid damaging evidence. Later steps (repairs, insurance, longer-term security changes) can be handled once you’re safe and the situation is clearer.
Important note
This is general information, not legal advice. If you believe anyone is inside or you feel at risk, prioritise immediate safety and call emergency services.
