How an assignment works with us
From the first phone call through the on-site appointment to sign-off with documentation: at every step you know who does what, when we arrive, and what ends up in your records afterwards.
The path to the order
Six steps, no surprises
We handle every order in the same sequence, whether it's a single socket or a meter cabinet in an apartment building. This makes appointments predictable and costs transparent.

1. Enquiry
You call +49 30 23125102 or write to info@elektro-hansen.invalid. We clarify over the phone what it's about, how urgent it is and whether an on-site appointment is needed.

2. On-site appointment
We inspect distribution boards, cable routes and the building fabric, take measurements and note what's already in place. For small jobs, we carry them out during the same appointment.

3. Quote
You receive a written quote with line items, materials and prices. Anything that can only be seen once a wall is opened is stated as a reservation, not hidden in the small print.

4. Scheduling
Once you give approval, we arrange the execution date, coordinating with property management or other trades if needed. You get a fixed time, not a half-day window.

5. Execution
We cover surfaces, work within agreed time slots and announce power cuts in advance. At the end of each working day, the system is left in a safe, usable condition.

6. Acceptance and documentation
We test to VDE standards, walk you through the system together and hand over the test report, wiring diagram and photos of the closed wall sections.
Before our visit
What you can prepare
A well-prepared appointment usually saves half an hour of labour time, which you would otherwise pay for. What matters most is that we can reach the meter cabinet and the affected walls without having to move furniture.
- Access to the meter cabinet, basement and utility connection room, including keys or an on-site contact for rental properties
- Around one metre of clear space in front of all wall areas where work will take place
- Meter number and grid operator's name, if a registration is required
- Floor plan or old wiring diagram, even hand-drawn or incomplete
- A note on which sockets, switches or light fixtures should go where
- For older buildings: notes on any known asbestos, damp or mould spots

Availability during the work
Responsibilities
Who handles which part
Most delays don't stem from technical issues but from unresolved questions of responsibility. That's why we put them in writing before starting.
Preparation
How to prepare for the appointment
The better the access and information available, the less time is lost on site - and the more accurate our cost estimate remains.
What you should have ready
- Access to the meter cabinet and, in multi-family homes, to the basement or riser shaft
- If available: wiring diagram, distributor labelling or the last inspection report
- Clear working space in front of sockets, switches and the sub-distribution board, roughly an arm's length
- For rental properties, the owner's permission for work on the fixed installation
- An on-site contact person who can authorise power shutdowns
What we bring
- Installation testers for loop impedance, insulation resistance and RCD trip times
- Thermal imaging camera to check for overheated terminal points in the distribution board
- Cable detector to locate live wires before drilling
- Low-dust drilling and milling equipment with extraction for occupied rooms
- Common circuit breakers, RCDs, sockets and switches as part of our vehicle stock
From practice
Common cases and how we solve them
We encounter four situations in Rendsburg and the surrounding area almost every week. Here's how we approach them – and how that affects duration and cost.
