Record Defect Rate in German Building Tech Fuels Urgency Behind New Safety Documentation Rules
03.07.2026 - 06:41:47 | boerse-global.de
9 percent of safety-related building technology systems failed inspections in 2025 — the highest share ever recorded. That figure stood at 26.1 percent in 2020. The surge has put fresh pressure on employers just as a stricter documentation rule for workplace safety takes effect across Germany.
The new Technical Rule for Operational Safety (TRBS) 1116, which came into force on 1 July 2026, requires employers to explicitly prove each worker’s qualification for every piece of equipment they operate. The regulation builds on existing DGUV Vorschrift 3 obligations and sharpens the focus on legally watertight record-keeping for fixed electrical installations and machinery.

Why the defect rate is climbing
Fire alarm systems, emergency lighting and ventilation units are the worst performers, according to the TÜV report. Experts blame ageing installations, a shortage of skilled maintenance staff, and growing cost and time pressures on companies. The 35.9 percent defect rate marks a jump of nearly ten percentage points in five years.
The central tool for determining inspection intervals remains the employer’s risk assessment. In practice, offices typically schedule checks every 24 months, while production facilities use 12-month cycles. A rule known as the 2 percent threshold applies: if more than 2 percent of tested items fail, the next interval must be shortened.
Digital records and longer validity periods
The federal government is working on a reform of the trade regulations (Gewerbeordnung) meant to ease the administrative burden on businesses. Introducing digital compliance records would eliminate roughly 5,000 on-site inspections per year. When companies change hands, permits for dormant sites would remain valid for up to seven years. The reform also plans broad exemption from permitting for photovoltaic systems and electric-vehicle charging stations.
Fire alarm systems and emergency lighting recorded the highest defect rates in the latest inspections — a growing risk for employers.

A separate court ruling from the Koblenz Higher Regional Court, handed down on 1 July 2026, clarified installation rules for solar panels. Contracts for complete PV installations are illegal unless the provider is registered in the skilled trades register. The court held that both roofing and electrical work are involved, making a formal trade qualification mandatory.
Cybersecurity enters the safety picture
Alongside physical inspection methods — visual checks, measurement of protective-conductor and insulation resistance, and testing of emergency stop devices, safety doors and light curtains per DIN EN 60204?1 — digital resilience is gaining prominence. The updated TRBS 1115?1 now addresses cybersecurity risks for work equipment. That shift reflects real-world damage: cyberattacks on German businesses cost an estimated 289.2 billion euros in 2025.
The Gartenbau-Versicherung, in a brochure published in early July, highlighted the importance of fire prevention through regular training and moisture protection in electrical areas. Companies face the dual challenge of safeguarding both the physical integrity of their electrical systems and hardening them against digital vulnerabilities.
