Giving up oil heating in Finland, 2026

Updated

Giving up oil heating carries an elevated household tax credit of 60% of the labour share, up to €3,500 per person. The Elinvoimakeskus grant, by contrast, is closed: applications ended on 25 May 2026 at 16.15, the appropriation was spent in full and over 300 applicants received nothing. No replacement has been decided (Elinvoimakeskus, 1 September 2026).

What the 60 % credit actually requires

Giving up oil heating altogether carries an elevated credit of 60% of the labour share, up to €3,500 per person, in force until 31 December 2027 (Verohallinto, 10 February 2026). It applies only to actually giving up oil heating: the boiler, burner, tank and pipes must all be removed. If oil heating stays as a parallel system the ordinary €1,600 cap applies. Of the €3,500, at most €1,600 may come from other qualifying work. The €3,500 cap is personal, just as the ordinary €1,600 is, so in a two-owner household each claims it separately against the share of the invoice they paid.

The grant is closed — do not budget for it

Plenty of pages still describe the grant in the present tense. The grant is closed. Applications ended on 25 May 2026 at 16.15, the appropriation was spent in full and over 300 applicants received nothing. It used to pay €4,000 / €2,500 depending on the replacement system (Elinvoimakeskus, 1 September 2026). No replacement scheme has been announced, so an oil conversion done in 2026 is financed by the elevated tax credit alone. Which is also the good news: a grant would have blocked the credit for the same work.

What replaces the boiler, and what it costs

Motiva has costed two example houses in which the old oil system is removed. Ground source: €23,000–€26,000 replacing oil heating, demolition included — 2 costed worked examples (Motiva, 2024). Air-to-water: €17,000–€18,000 replacing oil heating, demolition included — 2 costed worked examples (Motiva, 2024). Demolition is inside both figures, and that is exactly the difference that makes converting an oil house dearer than fitting the same equipment where there is nothing to remove.

If you did get the grant, there is no credit

A state grant blocks the household tax credit for the same work entirely, even when the grant does not cover all the costs and even when the parts of the job fall in different tax years. One measure cannot carry both a grant and the credit. (Verohallinto, 1 January 2025) That holds even when the grant covered only part of the cost, and even when the work fell across two tax years. If no grant was received, the elevated credit is available as normal.
