Electrical engineering for businesses in and around Rendsburg
We install, inspect and maintain the electrics of workshops, offices, practices and retail spaces – scheduling the work when it disrupts your daily operations the least.
Working with businesses
Work that doesn't bring your operations to a halt
In a business, every de-energized row of sockets costs time – which is why we clarify before the first move what needs to be de-energized and when.
We coordinate every job with your workflow: what stays running, which circuit can be shut down, which machine needs a restart. We schedule smaller jobs during off-peak hours and larger ones during downtime, holidays or stocktaking days.
The same person who conducted the on-site visit also carries out the work. This saves you from explaining things twice – and saves us the search for the distribution board.
- Shutdown windows agreed in writing beforehand
- Access, keys and alarm clarified before starting
- Work area left broom-clean afterward
- Documentation sent as PDF to your contact person
Services for businesses
From the distribution board to a fault on Friday afternoon
We look after workshop, office and retail spaces from initial installation through recurring inspections to repairs during ongoing operations.
Systems and distribution boards
New sub-distribution boards, expansion of existing distribution panels, additional circuits for machines, servers or workstations. We label every outgoing circuit and update the wiring diagram.
Lighting
Conversion of hall, office and retail lighting to LED, emergency and safety lighting, zone-based switching as well as motion and daylight control for secondary areas.
Testing of portable appliances
Recurring testing of extension cords, hand tools, kitchen appliances and office equipment in accordance with DGUV Regulation 3. Each device receives a test sticker, and you receive a report with a device list.
Fault repair
Failed circuits, tripping RCDs, defective switchgear: we narrow down the cause, restore operation and document what was actually faulty.
How a job works
Four steps to your inspection report
Every business job with us begins with an on-site visit and ends with documentation you can present during an inspection.
Process
How a job runs during ongoing operations
Production, sales floor or office should keep running. That's why we plan every appointment so that shutdowns remain brief, announced in advance, and limited to individual circuits.
Site visit and inventory
We walk through the installation with your responsible person, reviewing distribution boards, wiring diagrams and existing inspection reports. We note down system components that must not be shut down — cooling, servers, alarm systems, gate controls.

You receive a written quote with separate line items for materials, installation and testing. This includes the planned appointment, the duration per section, and which circuits will be de-energized during that time.
We work board by board. Before every de-energization, we inform the designated contact person, secure against reactivation, and restore the condition at the end of each section. Off-peak hours and Saturday appointments are possible by arrangement.
After installation, we measure insulation resistance, loop impedance and the tripping times of residual current devices (RCDs), and check the protective conductor connections. The values are entered into an inspection report according to DIN VDE 0100-600 and DIN VDE 0105-100 respectively.
You receive the inspection report, an updated distribution board plan and the wiring diagrams both digitally and on paper. On request, we note the next inspection deadline and get in touch with you in good time before it expires.
Costs
Inspection deadlines and what determines the price
For businesses, we bill based on effort — clearly itemized by travel, working time, testing services and materials.
Deadlines at a Glance
We generally inspect portable equipment — anything with a plug, from kettles to power drills — every one to two years, more frequently on construction sites. Fixed installations such as distribution boards, cabling and permanently connected machines are usually due every four years, while residual current devices (RCDs) are tested by you every six months using the test button.
The exact deadline is set out in your risk assessment. We propose it, provide the reasoning, and record it in the report.
These Factors Determine the Scope of Work
- Number of devices and circuits — equipment testing is priced per unit, installation testing by time
- Accessibility: suspended ceilings, blocked distribution boards and full shelves take extra time
- Condition of documentation — missing wiring diagrams must be recorded on site
- Working hours: appointments outside business hours are billed with a surcharge
- Scope of defect rectification directly commissioned alongside the inspection
You can reduce the effort involved by gathering devices in one place beforehand, clearing access to distribution boards, and providing a point of contact with keys.
