On the other hand, some things are being exaggerated here.
For the construction power, I just ran an extension cable to the neighbor.
Not 3,000-5,000€ at all.
In that case, I would rather buy a generator suitable for unbalanced loads.

When it comes to construction power, it’s not about the drill or angle grinder, but the screed heating program in these capacities 😉

Depending on whether it’s a new development area or infill construction, unfortunately there often is no neighbor within extension cable distance...

What are the disadvantages of connecting the electricity permanently when starting up the heating system?
That’s how I at least did it.

The schedules of the utility company, the unreliable electrician, faulty applications... All the challenges I’m experiencing here in the housing development area 🤨

Temporary construction electricity for 3,000–5,000€? Where do you live and how much does electricity cost there? We currently pay 33.4 cents per kWh for construction power. Apart from the heating program, there shouldn’t be much electricity use. Drying units and heaters are not necessarily required... Otherwise, many tools used by the builders run on batteries.

Just as an example for us:
Water connection all-inclusive 1,300€ for 5m (16 feet)
Electricity connection all-inclusive 1,500€ for 15m (49 feet)
Sewage connection free, own excavation contractor up to shaft 2,100€ including 25m (82 feet) DN110/160
Telecom all-inclusive 899€ for 15m (49 feet)

Unexpected additional costs for us:
Soundproof windows +5,000€
Radon sealing +5,000€
More excavation/removal 20,000€ instead of 10,000€ according to the quote

Otherwise, I think many requirements are far too strict here. There are also home builders who don’t have high demands.

Wow. My house connection point/multi-utility connection is exactly 4.5m (15 feet) away from the street where the lines are located.

When I calculate it, I’m easily at three times that amount.

Otherwise, many of the workers’ tools run on battery power

So far, every single tradesperson has charged spare batteries onsite using the power supply. The construction trailer with heating and coffee machine also consumes power. In winter, it’s essential; otherwise, you might not see the workers return...

A construction dryer and heater are not necessarily required...

But they can be. There are other forums besides this one, and over the last two years, energy consumption of 8,000 to 9,000 kWh was often reported, including screed drying programs plus 2 to 3 weeks of construction dryer use. If you end up with a poor electricity rate, which depends on the region, and it is above €0.40 per kWh, it doesn’t just hurt those who didn’t calculate costs at all. Those who have built know it’s always wise to budget an extra thousand euros. The money disappears quickly during construction. If you rely on a fixed price without double-checking or researching, you will eventually be in the red. However, it’s pointless to take a mentioned number here and compare it only to your own consumption from 2 to 4 years ago… I like to refer to the relevant threads such as “Why has building become so expensive” or the still current https://www.hausbau-forum.de/threads/warum-gehen-die-baupreise-nicht-runter.45529/

I keep being surprised and am slowly getting angry—E.ON in the north already increased the basic supply tariff to nearly 56 cents per kWh as of March 1. Luckily, we still had the Hotboy heating phase before that at 33 cents. That’s almost exciting in a twisted way.

Even when I compare electricity prices between the north and south, I could almost cry. In the north, I get the cheapest green electricity for 37 cents, friends in Franconia get it for 29 cents. Honestly, that makes me a bit angry.
Why is it so different?

Wow, that’s frugal.
In our case, it was over 8,000 kWh in the end. But that was for two houses with screed heating and delayed heat pump delivery and straw connection. That means for the first house the heat pump also ran for about two weeks on construction power.

I do think we could have just chosen a different electricity contract. The price per kWh was actually quite good at that time. I probably could have taken advantage of switching bonuses.

… and that is just about the construction power!
