Cheapest country in Europe to install a heat pump — 2026 ranking

The 2026 ranking: where heat-pump running costs are easiest to beat gas

For household running costs, the simplest screen is the electricity-to-gas tariff ratio: lower is better, because a heat pump needs electricity but displaces gas. Across the EU and EFTA set covered here, Sweden posts the lowest ratio at 1.3, with household electricity at €0.2711/kWh and gas at €0.2092/kWh (price_ratio / Eurostat household band DC (electricity) / D2 (gas), latest semester). The Netherlands follows at 1.49, with €0.2558/kWh electricity and €0.1719/kWh gas (price_ratio / Eurostat household band DC (electricity) / D2 (gas), latest semester). Then come Portugal at 1.73, France at 1.78, and Italy at 2.0 (price_ratio / Eurostat household band DC (electricity) / D2 (gas), latest semester).

That ordering matters more than headline grant size. A market with cheap electricity relative to gas is structurally easier for heat pumps than a market that relies mainly on subsidy. Readers can compare the broader country stack in the 32-country country comparison dashboard and the current market snapshot.

Top 10 lowest electricity-to-gas tariff ratios in 2026

Tariff figures and ratios from price_ratio; subsidy, HDD₁₈ and grid CO₂ from country_compare (price_ratio / Eurostat household band DC (electricity) / D2 (gas), latest semester; country_compare / Eurostat · NASA POWER · EEA · Househeating Pulse subsidy register).

A few immediate patterns stand out. Portugal, Italy and Greece combine low tariff ratios with relatively mild heating demand, while Sweden gets its ranking from exceptionally favorable fuel economics despite a much colder climate (country_compare / Eurostat · NASA POWER · EEA · Househeating Pulse subsidy register). France is the most balanced top-tier market: low ratio, middling HDD₁₈, low grid carbon and a large named subsidy (country_compare / Eurostat · NASA POWER · EEA · Househeating Pulse subsidy register).

The tariff ratio test: which countries clear the SCOP 4 break-even line

Using the editorial threshold in this piece, a heat pump with SCOP 4 beats gas on running cost when the electricity-to-gas ratio is below about 3.7. On that test, 22 countries are below the line, from Sweden at 1.3 down to Czechia at 3.35 (price_ratio / Eurostat household band DC (electricity) / D2 (gas), latest semester). Poland sits almost exactly on the threshold at 3.71, while Belgium at 3.9, the United Kingdom at 4.63 and Romania at 5.11 are above it (price_ratio / Eurostat household band DC (electricity) / D2 (gas), latest semester).

Countries with no household gas comparator in the registry cannot be ranked on this ratio at all. That includes Cyprus, Finland, Malta, Norway and Iceland, where gas price and ratio fields are null (price_ratio / Eurostat household band DC (electricity) / D2 (gas), latest semester). The registry does not record an implied gas benchmark for those markets.

For installers and buyers, this threshold is a quick triage tool rather than a full business case. The detailed arithmetic still depends on system design, emitter temperatures and real seasonal performance, which is why the payback calculator, SCOP leaderboards, and methodology notes are more useful than tariff ratios alone.

Subsidy check: where the biggest grants change the math the most

Among the leading ratio countries, the biggest named subsidy is in Poland at €31,000 maximum, despite its weaker tariff position of 3.71 (country_compare / Eurostat · NASA POWER · EEA · Househeating Pulse subsidy register; price_ratio / Eurostat household band DC (electricity) / D2 (gas), latest semester). That is exactly the kind of market where grants may do more work than the tariff structure itself.

For the top 10 ratio countries, the maximum publicly listed subsidies are:

(country_compare / Eurostat · NASA POWER · EEA · Househeating Pulse subsidy register)

The named programme details available in the corpus sharpen that picture. In Germany, BEG EM reaches €21,000 maximum, with a 70% cap on eligible costs up to €30,000, built from a 30% base plus bonuses for natural refrigerant or ground/water source, fast fossil replacement, and low household income (country_profile DE / Eurostat tariffs (band DC/D2 latest); NASA POWER 30y normal; EEA grid CO₂; subsidies captured manually from official programme pages). In France, MaPrimeRénov' reaches €11,000 for geothermal systems in the Bleu income band, while air-to-water support peaks at €5,000 and air-air is excluded (country_profile FR / Eurostat tariffs (band DC/D2 latest); NASA POWER 30y normal; EEA grid CO₂; subsidies captured manually from official programme pages). In the Netherlands, ISDE is much smaller for the common full air-to-water case at €2,750, though the rules list €4,000 for ground-source systems (country_profile NL / Eurostat tariffs (band DC/D2 latest); NASA POWER 30y normal; EEA grid CO₂; subsidies captured manually from official programme pages).

That makes Germany an example of a market propped up meaningfully by subsidy, while the Netherlands is attractive even before grant support because the tariff ratio is already 1.49 (price_ratio / Eurostat household band DC (electricity) / D2 (gas), latest semester). Readers comparing national programmes can use the subsidy index and country pages such as German heat-pump subsidies and French heat-pump subsidies.

Climate and grid carbon: why some cheap-tariff markets are still harder sells

Within the top 10 ratio countries, climate differs sharply. Portugal has just 851.63 HDD₁₈, Greece 1152.59, and Italy 1536.47, versus 4242.38 in Sweden and 5023.68 in Liechtenstein (country_compare / Eurostat · NASA POWER · EEA · Househeating Pulse subsidy register). So “cheap to install” in practice is often easiest in places that are not only tariff-friendly but also relatively mild.

Among the top-ranked ratio markets, the cleanest grids are Sweden at 14.0 g/kWh, France at 56.0 g/kWh and Liechtenstein at 28.0 g/kWh (country_compare / Eurostat · NASA POWER · EEA · Househeating Pulse subsidy register). The dirtiest within that same leading group are Greece at 360.0 g/kWh and Bulgaria at 358.0 g/kWh (country_compare / Eurostat · NASA POWER · EEA · Househeating Pulse subsidy register). That spread is large enough that the carbon case can diverge from the running-cost case.

France is the clearest example of a market that scores well on all four dimensions used here: ratio 1.78, max subsidy €11,000, HDD₁₈ 2759.65, and grid CO₂ 56.0 g/kWh (price_ratio / Eurostat household band DC (electricity) / D2 (gas), latest semester; country_compare / Eurostat · NASA POWER · EEA · Househeating Pulse subsidy register). The Netherlands also has an excellent ratio at 1.49 and moderate HDD₁₈ at 2901.04, but its grid is much dirtier at 268.0 g/kWh and its maximum named subsidy is much smaller at €2,750 (country_compare / Eurostat · NASA POWER · EEA · Househeating Pulse subsidy register). Sweden has the best ratio and one of the cleanest grids, but its HDD₁₈ is far higher at 4242.38 (country_compare / Eurostat · NASA POWER · EEA · Househeating Pulse subsidy register).

Country spotlights: Germany, France and the Netherlands compared head-to-head

Germany is not a top-tier tariff market. Its household electricity price is €0.3869/kWh and gas is €0.1223/kWh, for a ratio of 3.16, materially worse than France at 1.78 and the Netherlands at 1.49 (price_ratio / Eurostat household band DC (electricity) / D2 (gas), latest semester). But Germany compensates with the largest named subsidy among the three: €21,000 maximum under BEG EM (country_profile DE / Eurostat tariffs (band DC/D2 latest); NASA POWER 30y normal; EEA grid CO₂; subsidies captured manually from official programme pages).

France is the most rounded package. Electricity is €0.2561/kWh and gas €0.1436/kWh, for a 1.78 ratio; HDD₁₈ is 2759.65; grid CO₂ is 56.0 g/kWh; and MaPrimeRénov' reaches €11,000 maximum (country_profile FR / Eurostat tariffs (band DC/D2 latest); NASA POWER 30y normal; EEA grid CO₂; subsidies captured manually from official programme pages; price_ratio / Eurostat household band DC (electricity) / D2 (gas), latest semester). The subsidy also covers up to 90% of cost for the Bleu band, though product type and income band matter (country_profile FR / Eurostat tariffs (band DC/D2 latest); NASA POWER 30y normal; EEA grid CO₂; subsidies captured manually from official programme pages).

The Netherlands wins on tariff structure alone. Electricity is €0.2558/kWh and gas €0.1719/kWh, for a ratio of 1.49, better than both Germany and France (country_profile NL / Eurostat tariffs (band DC/D2 latest); NASA POWER 30y normal; EEA grid CO₂; subsidies captured manually from official programme pages; price_ratio / Eurostat household band DC (electricity) / D2 (gas), latest semester). But ISDE is only €2,750 for full air-to-water systems in the rules captured here, and grid CO₂ is 268.0 g/kWh, far above France (country_profile NL / Eurostat tariffs (band DC/D2 latest); NASA POWER 30y normal; EEA grid CO₂; subsidies captured manually from official programme pages).

For readers weighing system types, the split between air-to-water and ground-source matters because subsidy rules can differ sharply, especially in France and the Netherlands. The model side of that comparison is better handled through the live heat-pump catalog, the air-to-water SCOP leaderboard, the ground-source SCOP leaderboard, and the climate-fit analyzer.

What the ranking means for cross-border buyers and expat households

The easiest countries in 2026 are mostly the ones where electricity is already cheap relative to gas, not the ones with the single biggest cheque. Sweden, the Netherlands, Portugal and France all sit below 1.8 on the tariff ratio test, making them structurally favorable before any grant is applied (price_ratio / Eurostat household band DC (electricity) / D2 (gas), latest semester). Germany looks weaker on that metric, and Poland weaker still, but both become more competitive once maximum subsidy is considered (country_compare / Eurostat · NASA POWER · EEA · Househeating Pulse subsidy register).

For cross-border households, three cautions matter. First, subsidy figures are not perfectly comparable: some are lump sums, some are percentage-based with caps, and some depend on income or heat-pump type, as the Germany, France and Netherlands programme rules show (country_profile DE / Eurostat tariffs (band DC/D2 latest); NASA POWER 30y normal; EEA grid CO₂; subsidies captured manually from official programme pages; country_profile FR / Eurostat tariffs (band DC/D2 latest); NASA POWER 30y normal; EEA grid CO₂; subsidies captured manually from official programme pages; country_profile NL / Eurostat tariffs (band DC/D2 latest); NASA POWER 30y normal; EEA grid CO₂; subsidies captured manually from official programme pages). Second, climate still matters: Portugal’s 851.63 HDD₁₈ is a very different operating context from Sweden’s 4242.38 (country_compare / Eurostat · NASA POWER · EEA · Househeating Pulse subsidy register). Third, the carbon case may diverge from the cost case, with France far cleaner at 56.0 g/kWh than the Netherlands at 268.0 g/kWh (country_compare / Eurostat · NASA POWER · EEA · Househeating Pulse subsidy register).

The practical takeaway is simple. If the question is where the math works most easily, start with tariff ratio. Then layer on subsidy, climate and grid carbon. That sequence is also how the leaderboard hub, country profiles, and subsidy calculator are best used.
