Construction site electricity costs for shell construction without screed drying

You do realize that your nice neighbor has saved you the setup as well as the installation, setup, and rental of the construction power distributor? That quickly amounts to 500 to 800 euros in a few months, with electricity consumption charged at the "bargain rate" extra. He is definitely ahead with you there.

I would pay him the 900 euros or whatever that extra consumption amounts to, with the request to read the meter monthly during the next heating period; maybe his heat pump or controlled residential ventilation malfunctioned and then heated electrically... then you could sit down together again.

Now my question to you... Does anyone have any idea how I should proceed with this or where this enormous difference could come from.

It is quite simple: First, you pay the extra consumption without delay. If it is so important to you to find out what caused it, you can still start researching it later. Leaving the neighbor sitting with such a discrepant bill—no matter how it came about—I would find shabby. Also, haggling with the neighbor, who not only helped you but also saved you a lot of opportunity costs, would be bad form.

Seen this way: I agree exactly with , or .
