ᐅ Is it mandatory to install surge protection according to DIN VDE 0100-443/543?

Hello everyone,
My home builder informed me that there is a new standard requiring surge protection for buildings planned from October 1, 2016 onwards. Since our planning was completed before this date, we are not required to install it. So, it is optional for us. The cost is 810€ including VAT.
Since it’s not mandatory for us, I wanted to ask what you think about it. The primary purpose of surge protection is to prevent electrical devices from being damaged by power surges. See also the information sheet attached.
I guess it’s one of those cases where you pay for some safety and maybe sleep better during a thunderstorm. Many people never have a lightning strike causing damage, but there are certainly some who do experience damage.
Personally, I am leaning towards not having it installed.
What do you think?
Regards,
mading

What does such documentation look like? It would then have to be presented during the final inspection of the house, right? Text module:
The DIN 18014:2007-09 standard is still too new to be widely known by all parties involved in construction.
Compliance with the current DIN 18014:2014-03 is a prerequisite for meter registration. Although not all German electricians strictly follow the VDE subscription standards, many compensate with a seemingly supernatural ability to certify that the grounding system was installed according to standards even after concreting. If a grounding conductor is visible coming out of the ground, everything must be fine, right?
Search online for who is allowed to install foundation grounding. Forums are full of reports about grounding electrodes tossed in by bricklayers, and there is always someone who, out of concern for securing connection contracts, dishonestly completes the meter registration.

When installing lightning protection systems, surge protection for all supply systems was already required before October 1, 2017, according to DIN EN 62305 (VDE 0855-305). In contrast, according to the new standards, surge protection for low-voltage supply is mandatory regardless of official regulations. **CORRECTION:** Instead of VDE 0855-305, it should be VDE 0185-305.

So far, I’m missing a recommendation based on common sense.
We are currently facing the same question.
My feeling is that it worked fine for decades without it. So why should we spend money on it?
I would really appreciate your experiences from carrying out your own building project.

For me, there is a lack of recommendations based on common sense. Even before the saying about leaving the church in the village, common sense has often been claimed as justification for the worst messes, making the term, for me, a typical excuse.

DIN VDE 0100-443 and DIN VDE 0100-534 are standards independent of personal feelings, soon to be mandatory for new constructions because surge protection is a cost-effective preventive measure. Conspiracy theorists, however, see behind it the schemes of evil lobbyists.
As an otherwise standards-compliant electrical specialist, one could also consult the VDE selection guide for such questions.

Surge protection device in the distribution board by Hager
according to DIN VDE 0100-443
Modern electrical installations place increasing demands on comfort and communication. With the growing number of devices, the risk of surge damage to all equipment connected to the power, telephone, or data network rises.
Surge protection devices limit the voltage between the high voltage and low voltage sides, or at outlets up to 10 m (33 ft), to a safe level of approximately 1500 V. For cables longer than 10 m (33 ft), an additional surge protector is required for the device to be protected.
3-pole surge arrester T1+T2 22.5 kA TNC,
including connection to the grounding system
supply and installation
1 piece
Feed-in adapter for surge protection
supply and installation
7 pieces
Two-pole surge arrester DEHNflex,
Type 3 according to EN 61643-11, with
monitoring device and
disconnection feature
supply and install in front of the socket or roller shutter switch
What does this mean for me?
I just need help.
