ᐅ Cost Estimate for Electrical Installations

Hello dear forum members,

Soon we will begin building our house (southern Germany region, working with an architect).
We have already gained a lot of information and experience from this great forum and hope to be able to give something back in the future through sharing our own experiences.

On our trade/workscope and quotation list, the costs for the electrical installation currently seem very high to us.

The house has about 164 sqm (1,765 sq ft) to be equipped with electrical installations (light switches, sockets/outlets, LAN, 15 spotlights). Aside from a desired (video) intercom system for the front door, there are no special features (no smart home, etc.). Given the number of planned sockets, light switches, etc., we did not want to cut corners – so it can be considered rather well equipped but not overloaded.

The initial quotes have come in at around 28,000 gross (before tax).
The costs we know from other homeowners (with similar or even better equipment) are far lower. These ranged from 8,000 (standard quality) up to 15,000 (higher-end standard).

How did this item compare in your cases, assuming a similar scope?

Best regards

Many thanks for all the feedback! It’s somewhat reassuring. I will post the details here as soon as possible. Maybe there will be some additional tips regarding the installation itself, which would be very helpful.

Without going into wiring/circuitry now, that is really significantly overpriced.

However, I would argue that the equipment is somewhat above the normal standard. The video system alone will hit around 2-3k.

I would have guessed around 15k as well, which should already be on the high side.

Ok, thanks. €15,000 would also be our “gut feeling.” I’ll upload the wiring diagrams—still need to clarify rights regarding the plans.

Per child’s bedroom or total? Overall it’s okay.

You can really spend a lot here. There are branded switch series where a simple cover costs 4 euros and others over 25 euros. That’s an immediate difference of 2.5k.

Overall, I agree with Sebastian: based on your information and without details, I find it clearly overpriced.

Maybe you can upload the redacted quote.

The figure for the children’s bedrooms is TOTAL—so half per room.
I will upload the quote together with the plans.

Intercom system, outdoor equipment, and multiple-way switches drive the cost.

It sounds like a larger installation, but with too little networking.

Thanks for the note. There will be network access in every room, mainly for IPTV.
Since almost everything is on one level (a kind of floating bungalow), WLAN should suffice for the rest.

Then you just need to ask the electricians who worked for the other homeowners for a quote.

Could the recessed spots also be a cost driver? Depending on circumstances, of course…

The electricians from the other homeowners are located much further north, so that won’t help much.

Spots are certainly more expensive—especially the installation work, as I’ve heard. We are not big fans of recessed spots. In the bathroom and kitchen for support, okay—but the rest could be decorated more pleasantly with regular lamps, in my opinion.

Hello,
when I read “10LS” here, I wonder: is that 10 switches or 10 switch points? In the first case, there’s one location with 10 switches installed. In the other, 10 switch points with one switch each. I think you need much more detail than you have provided so far to assess this. For many multiple-way switches, I would recommend going towards KNX. Especially for higher-end installations, it’s cheaper (even if some don’t believe that)…

Regardless, €28k for a classic installation is quite expensive (for a house of this size).
Best regards,
Thomas

Ok. I will upload the plans soon and gladly open them up for discussion. The price assessment confirms the previous comments, thank you!

Also important: is the distribution board included? How many individually fused sockets (e.g., in the kitchen for dishwasher and each oven and the cooktop)? Light switches really matter—are there multiple-way switches and individual points? What about the spots… what should one imagine there?

The number of sockets does not seem excessive to me. In my 66 sqm (710 sq ft) apartment, I also have nearly 60 sockets.

What about roller shutter control?

The distribution board is included, yes. Basically, this is a complete offer from the electrician.
The other questions will probably be clarified by the electrical plans. To my knowledge, everything is fused individually where necessary.
The spots will be installed in the concrete ceiling.

About the sockets, one could probably save around 10% without major loss of comfort. But apparently, that is not the main cost driver.

Request quotes from more providers – including smaller companies as well.

Hello,

This is the current situation:

We requested a quote from another company, which represents the absolute minimum in terms of equipment for us. The cost is just over 15,000 (gross). We shared this new quote, with sensitive details redacted, with the first electrical contractor. The result: also just over 15,000 (gross). The switch system is a branded product from well-known manufacturers and falls into the mid-price range.

Personally, I think even this minimal option still seems quite expensive... What do you think?

Best regards

Unfortunately, I can’t offer much help since I am still in the planning phase myself, but am I understanding correctly that you are installing almost exclusively single sockets? Why not use double or triple sockets in certain places? Too expensive?

It should be reasonably affordable and, in my opinion, absolutely necessary—for example, in the living room behind the TV, in the kitchen, or on both sides of the bed in the bedroom.

I’m a bit confused; in the initial post you mention building in southern Germany, but the quote shows 20% VAT, and now your construction site is listed as Austria...

I find the costs for connecting the heat pump and the ventilation system quite shocking.

Apart from the fact that we did it ourselves, it was just three cables that were simply connected directly to the distribution board. The heat pump involved a bit more effort because of two additional meters. But in the end, maybe around 2 hours of work?

The number of outlets shown here is the minimum. We have increased it somewhat. Of course, there will be double and triple outlets exactly in the places you mentioned.

Regarding the construction site—you guessed right, it’s in Tirol. As a native of Bavaria, I consider my Tirol brothers part of Southern Germany. But the extra 1% VAT doesn’t seem like a significant cost driver to me.

That surprises me too, and I will inquire further. Especially the ventilation unit only has a power rating of 50 or 60 watts—I wouldn’t expect it to be complicated.

What do you all think about the individual prices for the different items? Fair / Not fair?
