Electricity contract omakotitaloon 2026
The electricity consumption of a detached house varies enormously depending on the heating method. With a ground-source heat pump or air-source heat pump, consumption is 5,000-10,000 kWh, but with direct electric heating it easily rises to 18,000-25,000 kWh. The choice of electricity contract can affect annual costs by up to 500-1,000 euros.

Which electricity contract suits omakotitaloon?
Spot price
A spot-priced contract is often the best choice for a detached house. High consumption means significant savings potential - especially when, with heating control, you can take advantage of the cheap hours.
Fixed electricity contract
A fixed contract protects against price spikes, which can be important in an electrically heated house. On cold winter days, the spot price can multiply, and with high consumption this shows on the bill.

Saving tips - omakotitalo
- Take advantage of storage electric heating or a hot water tank - load during the cheapest hours
- Install an air-source heat pump - it can lower heating costs by 30-50%
- Improve the house's insulation: window seals, additional insulation in the upper floor
- Set the room temperature to 20-21 °C - each degree lowers heating costs by about 5%
- Use smart heating control that optimises consumption according to the spot price
- Run the washing machine and dishwasher at night with a spot-priced contract - the saving is large for heavy consumers
Frequently asked questions
How much electricity does a detached house use?
Consumption varies between 5,000-25,000 kWh per year depending on the heating method. In a ground-source heat pump house, about 5,000-10,000 kWh; in a house assisted by an air-source heat pump, 8,000-15,000 kWh; and in an electrically heated house, 18,000-25,000 kWh.
Spot-priced or fixed contract for a detached house?
For heavy consumers, a spot-priced contract combined with smart heating control usually brings the best saving. If consumption is over 15,000 kWh, the price difference can be hundreds of euros per year. A fixed contract suits you if you want certainty and cannot time your consumption.
How does the heating method affect the choice of electricity contract?
With electric heating and ground-source heating, consumption is high, so the margin and kWh price become especially important. With air-source heat pumps and storage tanks, a spot-priced contract is particularly cost-effective because you can load heat during the cheapest hours.
What is the best electricity contract for an electrically heated detached house?
A spot-priced contract with a small margin and a low monthly fee is usually the cheapest. In a price comparison between electricity companies, look at the total price for an annual consumption of 20,000 kWh.
How much can be saved by switching electricity contracts?
In a detached house, the saving can be 200-1,000 euros per year depending on the current contract and consumption. The greater the consumption, the greater the potential saving.
Is a ground-source heat pump worthwhile from the electricity consumption perspective?
Yes. A ground-source heat pump typically reduces electricity consumption by 40-60% compared with direct electric heating. Direct electric heating of 20,000 kWh can fall to 8,000-12,000 kWh with a ground-source heat pump.
How do I monitor the electricity consumption of a detached house?
Almost all electricity companies have a mobile app where you can see hourly consumption. Smart meters report consumption automatically. You can also compare on an annual basis whether consumption has changed.
