Fortum electricity contracts 2026

About Fortum — Finnish electricity provider

Fortum is a Nordic energy company founded in 1998 and listed on the Helsinki Stock Exchange, with the Finnish state as its majority owner. Fortum operates in Finland, Sweden, Norway and the Baltics.

In Finland, Fortum emphasises 100 % renewable, carbon-neutral electricity — all the electricity sold in Finland is renewable or emission-free (hydro, wind, nuclear) and certified with certificates of origin. Fortum is one of the largest carbon-neutral electricity producers in the world.

Why choose Fortum for your electricity contract?

Fortum’s Hintakiinnitys feature is unique: you can start on a spot contract (Fortum Tarkka) and later lock the margin as a fixed price for a chosen period — getting the best of both worlds. Fortum Duo hybrid is another specialty: 50 % of your consumption is billed at a fixed rate, 50 % spot-based.

Who is a Fortum electricity contract best for?

Fortum suits the consumer who values a large established company, green electricity and comprehensive digital services — even though the margin is slightly higher than at smaller competitors. A particularly good choice if you want a Duo-style hybrid to balance spot risk.

Fortum customer service and reviews

Fortum offers comprehensive customer service (chat, phone, email), an app where you can track consumption and the spot price, plus the Hintakiinnitys service that lets you turn a spot contract into a fixed-price one for your chosen period.

How to sign up with Fortum step by step

You can sign a contract directly on the Fortum website — click the ”Choose” button in the Verrokit comparison to go straight to the order form. You will need your metering point identifier (on your current electricity bill) and your personal ID.

Your old contract ends automatically when the new one takes effect — Fortum handles the switch for you within 2–4 weeks. You do not need to notify your old provider or your local grid operator separately.

When to compare Fortum electricity contracts

The four most common triggers to reconsider your Fortum contract are: (1) your current fixed-term contract is ending — the provider often shifts you to an open-ended contract with a higher energy price; (2) you’re moving — a new address means a fresh comparison since the local grid operator changes; (3) your consumption has changed significantly — for example moving from an apartment to a detached house or installing electric heating; (4) market prices have shifted — a fixed contract signed when spot prices were high may no longer be the best value.

Verrokit’s comparison shows all Fortum’s current contracts alongside competitors sorted cheapest first based on your annual consumption. In two minutes you’ll know whether staying with Fortum or switching to another provider makes sense.

Fortum contract terms, cancellation and switching

Fortum — like all Finnish electricity providers — follows the electricity market rules confirmed by the Finnish Energy Authority. Open-ended contracts have a two-week notice period which you can invoke at any time without a fee. Fixed-term contracts run for their full term (typically 6, 12, 24 or 36 months) and early cancellation can incur a fee corresponding to the remaining months.

When your fixed-term contract ends, Fortum typically transfers you to an open-ended contract whose energy price is often higher than the market’s cheapest options. This is why it pays to compare before the term ends — Verrokit’s notification system helps you remember.

How to choose the right Fortum electricity contract

Take two minutes to check these four points before signing:

• Your annual consumption in kWh — find it on any recent electricity bill or from your grid operator’s online portal. The cheapest contract depends heavily on this number.
• Intro perks and when they end — many contracts show low prices for the first 3–6 months, then rise significantly. Check the normal price after the intro period.
• The type that suits you — spot electricity (variable, cheapest on average), fixed-term (predictable, no surprises) or hybrid (mix of both). Different profiles suit different consumers.
• Environmental values if important — check whether the provider offers 100% renewable electricity and whether guarantees of origin are included in the price or cost extra.

Fortum contract terms, cancellation and switching
