Construction costs are currently skyrocketing

For me, it was 150 kWh. So absolutely manageable. Heating up was done via [Nahwärme].

Wow, so economical.
In the end, we had over 8000 kWh. But it was also two houses with screed heating and delayed heat pump delivery as well as straw house connection. That means for the first house the heat pump also ran for about two weeks on construction power.

However, I believe we could have simply made a different electricity contract. The kWh price was quite good back then. At most, I could have taken advantage of switching bonuses.

It's not always just the pure consumption that matters. Here, you were placed in the "Strom Profi" tariff by Enso, which had a basic fee of around €200/year. So that's another aspect. And already mentioned it, switching bonuses is the keyword. Every month a different provider and you can already refinance your electricity costs ;) I speak from experience.

Who offers switching bonuses for a one-month term? Those used to be individual offers, but not the norm. Nowadays, definitely not.

Yes, I have also noticed that currently there are hardly any offers without a minimum term of 12 months. In my region, as far as I know, there are exactly two. One with a switching bonus, but it is only paid out after 12 months.

There were always some... And currently also with Shoop, no explicit information whether only 12 months or also monthly.
