Choosing the right electricity contract for a detached house makes a bigger financial difference than for any other household type. Annual consumption ranges from 5 000 kWh (district heating) to 25 000 kWh (direct electric heating) — a 1 c/kWh price difference means 150–300 € per year. This guide shows the cheapest contracts by heating type and reveals which contract length actually wins.

Frequently asked questions
What is a typical annual electricity consumption for a detached house?
It depends on heating: district heating 5 000–8 000 kWh, air-source heat pump + wood/oil 8 000–15 000 kWh, ground-source heat pump 10 000–15 000 kWh, direct electric heating 15 000–25 000 kWh. Check your last full year’s bill for the actual figure.
Is fixed-price or spot cheaper for a detached house?
On a multi-year average (2015–2024), spot has been cheaper 7 years out of 10. But with high consumption, a single bad winter (like Dec 2022) can cost €500–1000 extra on spot. For electrically heated homes, fixed-price is usually the safer bet unless you can actively shift consumption.
How much can I save by switching contracts?
For an electrically heated detached house (20 000 kWh/year), switching from a poorly-priced open-ended contract to a competitive 24-month fixed contract typically saves €200–500 per year. Over the 24-month term, that’s €400–1000 total.
