A smoke detector inspection scam in Germany is being used to gain access to people’s homes. Scammers pretend to be official inspectors and claim that they need to check whether smoke detectors, known as Rauchmelder, have been installed correctly.
How the scam works
The scammers may arrive without warning or send an official-looking letter or email before their visit.
They sometimes use convincing names such as “Brandschutz Deutschland 2026” to make the inspection sound like a government programme.
Once inside the home, they may:
- try to sell overpriced smoke detectors;
- pressure residents into unnecessary maintenance contracts;
- inspect the rooms and look for valuables;
- collect information that could later be used for a burglary.
In some reported cases, two people entered together and then moved into different rooms.
Official inspections are not normally unannounced
Smoke detectors are mandatory in residential buildings throughout Germany. However, this does not mean that government inspectors regularly arrive without notice to check private homes.
When a genuine inspection or maintenance appointment is required, tenants are normally informed in advance by:
- the landlord;
- the property management company;
- the building owner;
- an authorised maintenance company.
The responsibility for installing smoke detectors generally belongs to the property owner. Responsibility for regular maintenance can vary depending on the federal state and rental arrangement.
What should you do?
Do not let an unexpected visitor into your home simply because they claim to be checking smoke detectors.
Instead:
- Keep the door closed.
- Ask for the visitor’s name, company and identification.
- Contact your landlord or property management company directly.
- Use the telephone number from your rental contract or previous official correspondence.
- Do not call a number provided only by the visitor.
- Do not sign a contract or make an immediate payment at the door.
An identification card may also be fake, so always confirm the appointment independently.
If the visitor refuses to leave, behaves aggressively or tries to force entry, call the police on 110.
