ᐅ Electrical installation too expensive – oversized or just overpriced?

Hello everyone,
We received the quotation for the electrical installation, and I had to sit down first.
So far, everything has roughly matched the values found online (excavation, surveying, structural engineering, architect fees, etc.), but the electrical installation is about twice as expensive as what is generally indicated on the internet: €23,000, while we had planned for €10,000–12,000.
On closer inspection, we noticed that the quotation seems oversized and appears to cover all possible contingencies. The final billing is based on actual usage, so I would like to get your opinion on how over-dimensioned it really is. The prices include installation.
A few items can be deducted or reduced considerably. (For example, I do not need 17 temperature controllers with displays at €100 each), which would save about €1,000 right away. Also, a network cabinet with a patch panel listed at €400 can be found for about half that price. Having 110 sockets plus 10 Schuko sockets also seems excessive to me.
There are also elements included that I have not seen elsewhere: all installations (kitchen, heating, garage), roller shutter control and connection, ventilation installation, mailbox with intercom system. Still, I cannot get the total below €15,000, let alone €10,000.
Here are my top 10 items – is this very oversized? Or am I unlikely to save much? Especially the cable lengths are about double what I see online.
Room temperature controller €104.12, 17 pcs, €1,770.04
Sheathed cable 5*1.5 mm², €1.83 per meter, 700 m, €1,281.00
Socket outlet Jung AS520, €9.25, 110 pcs, €1,017.50
Meter cabinet €856.34, 1 pc, €856.34
Sheathed cable 3*1.5 mm², €1.41 per meter, 600 m, €846.00
Mailbox system with intercom €568.49, 1 pc, €568.49
Electronic transformer €29.43, 14 pcs, €412.02
Silicone protective cap €26.10, 14 pcs, €365.40
FR bathroom light €58.38, 6 pcs, €350.28
Residual current circuit breaker €68.26, 5 pcs, €341.30
Roller shutter: programming €338.71, 1 pc, €338.71

If you use cheap stuff, that can definitely happen.
Dusting should also be mandatory for these parts. It definitely wasn’t cheap stuff. I don’t know any standard power strip that faces upwards and is protected against this (not in the price range below 40 Euros). Dusting alone is not enough, and who does that thoroughly anyway (children even less so), especially if you have everything covered with dust (areas like under the bed, desk, etc. are particularly vulnerable).

With the effort and cost involved, you can definitely have better ones installed in the wall, and if the electrician isn’t overcharging, it’s not that expensive. That’s the point. Even though I would also securely install mine (for example, at the PC, one with a relay that independently switches everything on/off), I don’t think many people do it that way.

Sebastian7924 Jan 2016 19:50There are enough general contractors who would charge a fortune for that – so in this case, I would carefully consider how many I really want to install.
For me, the plan is to have only one power strip in the living room.

The fact that most electricians install a 16A circuit breaker regardless of what is connected afterward does not mean this is the correct approach, especially in a single-family home... usually, you hear the saying "we have always done it this way"... this is what I meant in terms of safety.
There are other factors as well, such as the installation method, cable length, and so on.
The 3600-watt limit does not always apply... sometimes the limit is 3000 watts or even less.
If the electrical circuits are properly divided, they can safely be connected to a single phase without any problems.

Safety is also an important argument, because especially multi-socket outlets lying around can quickly get dirty or exposed to moisture, particularly in a child's room. I once saw one start to smolder. It definitely would have caught fire if no circuit breaker had tripped. Fortunately, I noticed it in time.
If an outlet or device has a problem, the RCD trips, or something is seriously wrong...
I also don’t understand why some still use 3 x 1.5 mm² wiring for outlets; for me, outlets require 3 x 2.5 mm², PERIOD.
