Recent German court decisions require PV system registration; DGUV updates testing intervals for office, workshop, and construction equipment; balcony solar limits and critical infrastructure thresholds also change.
A series of recent court decisions in Germany is forcing electricians, roofers, and facility managers to rethink their obligations. The Oberlandesgericht Koblenz ruled in early June 2026 that comprehensive photovoltaic (PV) packages — spanning planning, installation, and maintenance — require registration in the Handwerksrolle (the official register of trades). The judgment, not yet legally binding, directly impacts electrical professionals and roofing contractors alike.
That ruling is part of a broader wave of regulatory updates affecting everything from office toasters to large-scale power connections.
On 23 June 2026, the Deutsche Gesetzliche Unfallversicherung (DGUV) published updated mandatory reference intervals for inspecting electrical equipment. For portable devices in offices, the standard check is now due every 24 months. In workshops that interval shrinks to 12 months, and on construction sites equipment must be tested every three months. Fixed installations are to be inspected every four years.
With the employer’s risk assessment now acting as the deciding factor for inspection frequencies, having well-documented, up-to-date risk assessments is more critical than ever. Yet many organisations still rely on incomplete or outdated documentation that leaves gaps in compliance. A free risk assessment toolkit provides 41 ready-to-use templates and checklists covering everything from fire safety to lone working — all designed to help you meet current UK requirements.

The DGUV emphasises these are guidelines, not hard rules. The employer’s risk assessment remains decisive. A key trigger for shortening intervals: if the fault rate during inspections exceeds two percent, checks must happen more frequently. Notably, privately owned electrical devices brought into the workplace by employees also fall under the testing regime.
One day earlier, on 22 June 2026, the revised DGUV Information 203-07 was released. It targets persons qualified to perform inspections and serves as a practical companion to the VDE standards VDE 0701-0702 (for portable equipment) and VDE 0105-100 (for fixed installations).
Alongside the regulatory updates, digital inspection tools are gaining traction. Since June 2026, new software solutions allow inspectors to document legally compliant checks using smartphones or tablets. These systems enable photo documentation, link inspection reports to job orders, and support automated maintenance scheduling.
Two state courts — the Landgerichte Bochum and Osnabrück — clarified safety requirements for balcony solar systems (Balkonkraftwerke) on 22 June 2026. Storage systems with a PV capacity exceeding 960 watts may no longer be sold without specific line-overload protection. The underlying standard, DIN VDE V 0126-95, permits simple plug-in feeding only up to that threshold.
At the end of May 2026, the Federal Ministry of the Interior released a draft for a new Kritisverordnung (Critical Infrastructure Ordinance). Under the proposal, facilities connecting generation plants to the grid would be considered critical infrastructure from a capacity of 104 MVA. The thresholds are based on the supply needs of 500,000 people.
As the pace of regulatory change accelerates, keeping your entire health & safety documentation aligned with current standards is essential. Over 37,000 UK businesses already trust a free health & safety toolkit that includes risk assessments, COSHH checklists, and more – all immediately available for download.

Given the accelerating pace of rule changes, ongoing professional training has become essential. Specialised seminars covering annual instruction for portable equipment testing or the model line-installation directive for fire protection help companies stay compliant with evolving safety standards.
