Overview
- Brandenburg, Bremen, Hamburg, Mecklenburg-Western Pomerania, Lower Saxony, Saxony and Saxony-Anhalt reach major replacement milestones in 2026, with further waves in 2027 for Berlin, North Rhine-Westphalia and Saarland, and in 2028 for Bavaria and Thuringia.
- Owners and landlords are responsible for installation, annual maintenance and replacement, while tenants are not obligated to manage deadlines.
- The deadline is calculated from the device’s manufacture or installation date printed on the unit, making a date check essential to determine each detector’s end of service life.
- Insurers may question claims if required devices are not maintained, and failure to install mandated detectors can draw fines reportedly up to €50,000.
- Safety experts urge early planning for 2026 to avoid possible supply bottlenecks and price increases, recommending certified Q-label models with 10-year batteries that typically cost about €10–€20 per unit, with premium options priced higher.
