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

Some items can be removed or are oversized. (For example, I don’t need 17 temperature controllers with displays at €100 each), that would quickly save about €1,000. Also, a network cabinet with a patch panel for €400 can be had for half that price. 110 sockets plus 10 Schuko sockets also seem oversized to me.

Here is my top 10—is this very oversized? Or won’t I be able to save much?
Just the cable lengths online are at most half the length.
Room temperature controller €104.12 17 1,770.04
Sheathed cable 5*1.5 mm² €1.83 700m (€770 yards) 1,281.00
Socket Jung AS520 €9.25 110 1,017.50
Meter cabinet €856.34 1 856.34
Sheathed cable 3*1.5 mm² €1.41 600m (€655 yards) 846.00
Mailbox system with intercom €568.49 1 568.49
Electronic transformer €29.43 14 412.02
Silicone protective cap €26.10 14 365.40
FR tub light €58.38 6 350.28
Residual current device €68.26 5 341.30
Shutter programming €338.71 1 338.71It would be interesting to know if the sockets are also connected with 3 x 1.5 mm² (square millimeters) cables, or if there is a separate entry for 3 x 2.5 mm².
You mention 110 outlets plus 10 Schuko sockets—isn’t everything Schuko nowadays?
In general, I can say we ordered and installed everything ourselves. Material from a low-cost online vendor was between €7,000 and €8,000 (without KNX or similar, but including 7 relatively expensive master-slave shutter controllers, and a large Hager meter cabinet, about 200m (220 yards) CAT7 and 200m (220 yards) satellite cables, remote-controlled dimmer…
Labor to install all this would probably be about the same amount again.
Honestly, 110 sockets seems quite a lot depending on the size of the house, as well as 10 or more sockets per room.
With our general contractor, there would probably have been about 45 “standard” outlets; we have installed around 75 (7–8 per room), which I find reasonable—I don’t want to cover every wall with sockets and switches, etc.

We also decided not to use temperature controllers, and like Sebastian, I would also recommend against them... they just don’t make sense in a modern house with low-temperature heating.I can’t really say that. My mother-in-law doesn’t have thermostats and keeps complaining—here she would prefer it a bit cooler, there a bit warmer... Sure, you can regulate the temperature with the supply temperature, but sometimes I might want to quickly turn the heating up or down without constantly adjusting the heating curve. They don’t have to be thermostats with displays or anything fancy—simple ones usually cost around 15-20 euros (about $16-$22)!

a bit cooler, because a bit warmer...A proper hydraulic balancing helps here.
Nothing works quickly anyway… with or without thermostats.
Yes, you can have the “iron meters” installed for 15-20 euros, but even the simple thermostats consume electricity and need to be installed, which all costs money—and you can save all of that because the benefit of ERR later tends to be close to zero…
