What does a heat pump or a solar array cost, installed?
Five prices, each with its sources and their dates. Then the installers in your city.
The bars are each source’s own range on one scale. Bars that overlap mean the sources agree.
Credits and grants, with their dates
Household tax credit: 35% of the labour share of a company invoice, up to €1,600 per person per year, with a €150 own share (Verohallinto, 10 February 2026).
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).
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).

What we check, and what we refuse to claim
Companies come from public registries: the trade register (PRH/YTJ) and the Tukes register of operators. Every listing links to the registry so you can check the same thing yourself.
Prices come from named sources. Each figure carries its source, that source’s own date and its sample size — including when the sample is two jobs.
We do not show star ratings, because we do not have any. We do not show one company’s price, because we have not verified it. We do not give a price as a single number, because no such number exists.
