Electricity Contracts for Detached Houses in Finland
Compare electricity contracts for a detached house using your household’s actual annual consumption. Heating can make a major difference, and a small per-kWh rate difference can add up at higher usage. No contract type is automatically best for every home.
Compare contracts using your own consumption ↓Compare electricity contracts using your annual consumption
Enter your postcode and your household’s actual annual usage or a personal estimate. The comparison uses current product data and the existing total-cost calculation.
Product details come from open data published by the Finnish Energy Authority’s Sähkönhinta.fi service. Fiksusti syncs the catalogue and filters it by postcode and your choices. We rank results by estimated annual cost using your stated consumption and the product’s energy and monthly charges. Electricity retailers are responsible for product information.
Illustrative example of an energy-rate difference
A 1 c/kWh difference equals €0.01/kWh. These examples show only the calculated annual effect of that rate difference; they are not market prices or default household usage.

How to choose an electricity contract for a detached house
Use your household’s annual consumption
Electricity use varies widely between detached houses. Check the past 12 months on a bill or in your supplier’s online service and use that figure for comparison. If you do not have a usage history, enter an estimate based on your own circumstances; the calculator does not assign a default based on house type.
Heating has a major effect on usage
Electric heating can substantially increase annual usage compared with a home where space heating is not electric. District heating supplies space heat separately, while ground-source and air-source heat pumps use electricity in different ways. Other heating systems also matter. The exact consumption cannot be inferred from the heating label alone.
How a 1 c/kWh rate difference adds up
A 1 c/kWh energy-rate difference equals €0.01 for each kilowatt-hour used. As an illustrative calculation, the difference is €50 a year at 5,000 kWh, €100 at 10,000 kWh and €200 at 20,000 kWh. These are simple examples of the arithmetic, not market prices or assumed usage for detached houses.
Include the standing charge in total cost
The annual effect of a monthly standing charge is 12 times the monthly fee. For example, a fee of X per month equals 12 × X per year before any product-specific discounts. Energy rates may have a larger relative effect at higher usage, but standing charges still matter. Compare both.
Is spot-price electricity right for a detached house?
The spot price changes over time. At higher usage, price movements may have a larger effect in euros, and shifting some consumption can affect cost. If heating uses a lot of electricity, heating schedules and your tolerance for price changes matter too. Spot-price electricity is not automatically the cheapest or most expensive choice.
Fixed pricing and contract duration are different
A fixed rate describes the energy pricing model; fixed-term and open-ended describe contract duration. A more predictable rate can make energy costs easier to plan, but it does not guarantee a cheaper contract. Check the product price and terms.
Fixed-term or open-ended?
Contract type describes whether a duration has been agreed or the contract continues open-ended. It does not by itself determine whether the price is fixed or spot-linked. Check each product’s terms, duration and price-change information instead of inferring them from the contract label.
Electric cars and electricity contracts for houses
Charging an electric car at home can increase household electricity use. The effect depends on driving distance, the car’s efficiency, how much charging happens at home and when you charge. There is no single annual usage figure for every car. With spot pricing, charging time can affect the energy cost.
Sauna, hot water and other large loads
An electric sauna, hot-water tank, underfloor heating, home EV charging and space heating can all affect annual usage. If any of these change, last year’s usage may not represent the coming year. Use the best household-specific estimate available.
What is the cheapest electricity contract for a detached house?
The cheapest option depends on annual usage, postcode and availability, energy rates, standing charges, promotions and pricing model. Results are ranked by estimated total cost where current product data supports a calculation. There is no single cheapest contract for every detached house.
Electricity supply and distribution are separate
Fiksusti compares electricity supply contracts. Distribution and network charges are separate, and the local network operator cannot be switched in the same way as the electricity supplier. Do not confuse a supplier’s standing charge with distribution fees.
