You know your MacBook's serial number by heart, know exactly which Adobe licenses expire and when, and keep track of every project milestone. But be honest with yourself: How many power strips are actually lying under the desks in your agency? No idea? Welcome to the club. Most creative entrepreneurs have a blind spot when it comes to their electrical devices. Yet a risk lurks here that, in the worst case, can cost you your livelihood. Not because you do bad work, but because you are ignoring a regulation you may have never heard of.
The Key Points in Brief
Every employer in Germany is legally obligated to have all electrical equipment tested regularly. DGUV Regulation 3 prescribes a maximum testing interval of 24 months for office equipment, provided the failure rate stays below two percent. The test must be carried out by a qualified electrician and costs between three and eight euros per device. In the event of violations, you face not only fines but also the complete loss of insurance coverage in the event of damage.
Why does hardly any agency count its electrical devices?
The reason is simple: Electrical devices have become invisible. They just work. You plug in the laptop, the monitor lights up, the coffee machine brews. As long as nothing breaks, the topic doesn't exist. Your head is full of client projects, deadlines, and the question of how to win the next pitch. There's no room left for the question of whether the power strip under the meeting table is actually still in good condition.
On top of that comes a dangerous assumption: New devices are safe. After all, they have a CE mark and come from renowned manufacturers. What many people don't know: The CE marking only confirms that the device complied with European directives at the time of production. It says nothing about how the device behaves after two years of intensive use. Cables get kinked, plugs wear out, housings develop cracks. Creeping defects often go unnoticed for months, until suddenly a short circuit trips the fuse. Or something worse happens.
The creative industry also has a special relationship with technology. You buy the latest equipment because it makes your work better. But you see it as a tool, not as a potential source of danger. Yet the accident statistics of the Institute for Research on Electrical Accidents of the BG ETEM show that between 3,500 and 4,000 electrical accidents are reported annually. Around 88 percent of these occur in the low-voltage range, exactly where your office devices operate.
How many devices are really hiding in your office?
Do a little exercise now. Walk through your office in your mind and count along. A typical workstation in a creative agency today consists of at least one laptop or desktop PC, often two external monitors, a docking station, mouse and keyboard, a USB hub, and a desk lamp. That's already seven devices per person. For designers, graphics tablets are added; for video producers, external hard drives and card readers.
Then there is the shared equipment. In the hallway stands the network printer, maybe a scanner as well. In the server room or IT corner you'll find routers, switches, a NAS for data backup, and possibly an uninterruptible power supply. In the meeting room hangs a projector or flat screen, plus video conferencing equipment with camera and microphone. In the kitchen there are a fully automatic coffee machine, kettle, microwave, and refrigerator.
And now comes the part that truly nobody has on their radar: the power strips and extension cords. Under every desk lies at least one power strip, often two or three plugged into each other. In an agency with ten employees, this quickly adds up to 20 to 30 power strips, all of which also count as portable electrical equipment and must be tested.
The calculation shows: An average ten-person agency easily has over 100 electrical devices subject to testing. For larger teams or studios with elaborate video technology, it can be 200 or more. Very few entrepreneurs have a complete list of them.
What makes DGUV Regulation 3 a top-management matter?
DGUV Regulation 3 is not a voluntary recommendation but a binding accident prevention regulation of the German Social Accident Insurance. It is based on the Occupational Safety and Health Act and the Industrial Safety Ordinance. The core requirement is: All electrical installations and equipment must be tested before initial commissioning and at regular intervals thereafter.
The crucial point: The responsibility lies with you as the entrepreneur. You can delegate the execution of the test, but not the responsibility for ensuring that it takes place. Even if you commission an employee or external service provider, you remain obligated to ensure that the tests are carried out properly and on time. In the event of damage, nobody asks the tester, they ask you.
The testing intervals are set out in the implementation instructions for DGUV Regulation 3. For portable electrical equipment in office environments, a guideline value of six months applies. If the failure rate determined during the tests is below two percent, the interval can be extended to a maximum of 24 months. This means: At least every two years, every single device in your office must be checked by a qualified electrician. For construction sites or workshops, significantly shorter intervals of three to twelve months apply.
The testing of portable electrical equipment consists of three parts. First, a visual inspection for external damage such as defective cables, broken housings, or damaged plugs takes place. Then follows the measurement test with calibrated measuring instruments according to DIN VDE 0701-0702. In this process, protective conductor resistance, insulation resistance, and leakage current are measured. Finally, a functional test is carried out. All results are documented in a test report, and the tested device receives a test sticker that shows the next test date.
Which devices may you test yourself and which not?
The answer is more nuanced than many think. In principle: The measurement test with measuring instruments must be carried out, or at least supervised, by a qualified electrician. This is someone who, through training, knowledge, and experience, is able to assess the work assigned to them and recognize possible hazards. As a rule, these are trained electronics technicians, electrical technicians, or electrical engineers.
There is an exception for persons instructed in electrical matters. These are employees who have been instructed by a qualified electrician about their tasks and the possible dangers of improper behavior. They may carry out certain tests under the direction and supervision of a qualified electrician if they use suitable measuring and testing devices. In practice, this means: You could have an employee trained who then takes over the routine tests. However, a qualified electrician must bear the responsibility and monitor regularly.
What you can and should do yourself, without special qualification, is the regular visual inspection. Here you look out for obvious defects such as damaged cables, loose plugs, cracks in the housing, or burn marks. The functional test of residual-current circuit breakers by pressing the test button is also part of it. In stationary installations this should be done every six months, in non-stationary installations such as construction sites even every working day.
✅ What you may test yourself:
☐ Visual inspection for external damage ☐ Checking cables for kinks, cracks, bare spots ☐ Checking that plugs sit firmly and are not damaged ☐ Pressing the test button on the RCD circuit breaker ☐ Checking that devices are set up properly
❌ What a qualified electrician must do:
☐ Measurement testing with calibrated instruments ☐ Measuring protective conductor resistance and insulation resistance ☐ Determining leakage current ☐ Creating the legally compliant test report ☐ Assessment and approval of the equipment
What does ignoring it really cost you?
The consequences of a neglected electrical test escalate in several stages. The first stage is fines. The technical supervisory officers of the employers' liability insurance associations carry out spot checks. If it is found that you are neglecting your testing obligations, this can be sanctioned directly with a fine. The amount is in the four-digit range and can increase significantly with repeated violations.
More serious is the loss of insurance coverage. If damage occurs due to a defective electrical device and you cannot present a valid test report, the insurer can refuse to settle the claim. This applies both to business liability insurance and to fire insurance. One third of all fires in the commercial sector are caused by electrical defects. If your office is damaged by a cable fire and the insurer doesn't pay, you bear the entire damage yourself. With a medium-sized fire damage, we're quickly talking about 50,000 euros and upward.
The third stage is personal liability. As managing director or owner, you are responsible for occupational safety. If an employee is harmed by a defective device, this can have criminal consequences. The employers' liability insurance association will then seek recourse from you for all costs incurred, from medical care through rehabilitation to possible pension claims. In the case of serious accidents or fatalities, prison sentences are possible. That sounds dramatic, but it is the legal reality.
A concrete scenario: In your agency, a defective power strip smolders under a desk. A smoldering fire starts, the smoke detector goes off, everyone can leave the building. The property damage amounts to 80,000 euros. The insurer investigates and finds that no current test reports exist. It refuses payment. You are left with the entire damage. At the same time, the public prosecutor's office investigates for negligent arson. The employers' liability insurance association examines whether it can claim recourse from you for downtime and treatment costs of an employee who inhaled smoke.
How expensive is the test compared to the damage?
After the horror scenario, now the good news: The costs of a proper electrical test are manageable. For testing portable devices, you pay between three and eight euros per device, depending on the provider and quantity. For larger quantities, the unit price drops. Some service providers offer flat-rate packages for small businesses starting at 99 euros.
Let's calculate this for a typical ten-person agency with 100 devices. At an average price of five euros per device, you arrive at 500 euros for the complete test. Possibly travel costs are added, but these stay within reason with regional providers. If you carry out the test every two years because your failure rate is low, the annual costs are 250 euros. That's less than 21 euros per month, less than a streaming subscription.

The calculation is clear: The testing costs are in no proportion to the potential damage. Even if you never have a damage case, with the test you buy legal certainty and the assurance that your devices are in order. The costs are also tax-deductible as business expenses.
As for the time required: Testers count on about ten to twenty minutes per device if everything is easily accessible. For 100 devices, you should therefore plan on one working day. Most service providers are flexible and can also carry out the test outside core working hours or on a quiet Friday afternoon so that operations are not disrupted.
How do you build a testing system that manages itself?
The biggest hurdle is not the test itself but the start. Once set up, a good system runs almost on its own. Here is a five-step plan that has proven itself in practice.
Step 1: Create an inventory. Take a morning and go through your office room by room. Record every electrical device in a simple spreadsheet with designation, manufacturer, location, and year of purchase. Don't forget the devices under desks, in cabinets, and storage rooms. In the end, you have a complete list of all equipment. This list is also the basis for your asset accounting and insurance.
Step 2: Carry out a risk assessment. For each area, assess what stresses the devices are exposed to. Office devices at a fixed workstation are subject to low stress. Devices that are moved frequently, such as laptops or presentation technology, have a higher risk of cable damage. Devices in the kitchen are exposed to moisture. From this assessment, the individual testing intervals for your business result.
Step 3: Select a testing service provider. Get quotes from two to three providers. Pay attention not only to the price per device but also to the scope of services. A good service provider creates legally compliant test reports according to DIN VDE 0701-0702, sticks test stickers on the devices, and offers a reminder service for the next test date. Also ask whether the provider can take over the initial inventory, which saves you time.
Step 4: Coordinate the test date. Agree on the date with your team and inform all employees in advance. Ask them to make their workstations accessible and to untangle cable clutter as far as possible. The better the preparation, the faster the test goes. Ideally schedule the date for a quieter day when not everyone has to be in the building.
Step 5: Establish the system. After the first test, you have clean documentation and know exactly when the next test is due. Enter the date in your calendar, ideally with two reminders: one three months beforehand for comparing quotes, one four weeks beforehand for scheduling. That way you'll never forget the date again. Also keep the inventory list up to date continuously: Every new device is entered, decommissioned ones are removed. At the next test, you simply hand the service provider the current list.
FAQ
Does the testing obligation also apply to freelancers without employees? Strictly speaking, DGUV Regulation 3 applies to all entrepreneurs with employees. As a solo self-employed person without employees, you are formally not obligated. However, your business liability insurance or fire insurance may nevertheless demand proof of the proper condition of your electrical devices. In the event of damage, you are on the safe side if you can document tests.
What about devices in the home office? Devices that you as an employer provide for the home office are also subject to the testing obligation. This applies to laptops, monitors, docking stations, and also to power strips that you give to employees. The test can either take place on site at the employee's home, or the devices are brought to the office at regular intervals. You should record the exact organization in a home office agreement.
Do I have to test my employees' private electrical devices? Yes, as soon as a private device is used at the workplace, it becomes equipment within the meaning of the Industrial Safety Ordinance. This applies to the private coffee machine in the kitchen just as much as to the smartphone charged at the USB port of the company computer. You should therefore set clear rules: Either private devices are prohibited, or employees must register them so that they can be included in the test.
How long do I have to keep test reports? There is no legally specified retention period specifically for test reports under DGUV Regulation 3. As a rule of thumb: Keep the reports at least until the test after next, so with a two-year cycle at least four years. In the event of damage, it may be necessary to prove the proper condition over a longer period. Retention for ten years, analogous to other business documents, is recommended.
Can I set testing intervals myself? You must determine and set the testing intervals yourself as part of your risk assessment. DGUV Regulation 3 provides guideline and maximum values. For office devices, the maximum value is 24 months if the failure rate stays below two percent. You can choose shorter intervals if the stress is higher. Longer intervals than the maximum values are not permitted.Can the inventory be combined with the test? Yes, that is actually very sensible. Many testing service providers offer to create a complete inventory at the same time during the first test. All devices are recorded, given an inventory number, and documented in a database. This way you kill two birds with one stone and afterwards have a clean overview of your entire device stock.
