Electricity contract lämmityskaudelle 2026
The heating season from October to April makes up 70-80% of a Finnish home's annual electricity costs. Choosing the electricity contract before the heating season is one of the year's most important financial decisions - especially in an electrically heated house. In summer electricity prices are typically at their lowest, and that is the best time to assess the contract situation for the coming winter.

Which electricity contract suits lämmityskaudelle?
Spot price
Spot pricing is the cheapest in the long run during the heating season too. On an annual basis the cheap summer months offset the higher winter prices. With smart control spot pricing is unbeatable - consumption is automatically timed to the cheapest hours even in winter.
Fixed electricity contract
A fixed contract is a good choice if you want peace of mind against winter price swings. Particularly for a heavy consumer (over 15,000 kWh/yr), the predictability of a fixed contract can be valuable. The best price is obtained by signing the contract in summer.

Frequently asked questions
When is the best time to compare electricity contracts for winter?
The best time to compare electricity contracts is June-August, when market prices are at their lowest. A fixed contract is usually obtained most cheaply in summer because electricity companies price future expectations into the contract - and in summer those expectations are more moderate.
Why is electricity more expensive in winter?
In winter, demand for electricity grows because of heating while wind and solar production decreases. In the Nordic electricity exchange the price is set by supply and demand - high demand and low production push the price up. During severe cold spells the price can multiply.
Is it worth taking out a fixed electricity contract for the heating season?
It depends on your risk tolerance and consumption. A fixed contract protects against price spikes, but on an annual basis spot pricing is usually cheaper. A good compromise is spot pricing with smart control - you can take advantage of cheap hours while the impact of price spikes is limited.
How do I prepare for the heating season in terms of electricity?
The three most important things: 1) Compare electricity contracts in July-August and switch if necessary. 2) Service the heating system - clean the air-source heat pump's filters and check the thermostats. 3) Seal windows and doors. Together these three measures can save hundreds of euros during winter.
How much does electricity cost during the heating season compared with summer?
The average spot price in winter months is typically 2-4 times higher than in summer. In summer the average price can be 3-5 c/kWh, while in January and February it is often 8-15 c/kWh. During individual freezing hours the price can rise to more than 30 c/kWh.
How does smart control help during the heating season?
Smart control automatically shifts heating to the cheapest hours. In winter this typically means night-time hours and the quieter moments of the day. The house's thermal mass keeps the temperature even during expensive hours too. The saving is 15-30% compared with constant uniform heating.
