France 2026: the heat-pump day–night tariff gap is still wide

France’s current tariff picture: what households pay today

France’s latest household electricity tariff is €0.2561/kWh, while household gas is €0.1436/kWh, leaving an electricity-to-gas ratio of 1.78 — far below the roughly 3.7 break-even line often used for a SCOP 4 heat pump versus a gas boiler, so the headline case for heat pumps in France is not being driven by a favourable power-to-gas tariff ratio alone (country_profile) (price_ratio).

That matters because the French retail-power story is mixed. On one hand, the latest electricity price is down from the recent peak of €0.2926/kWh in 2024-H2 by €0.0365/kWh, or about 12.5% (tariff_history). On the other, it is still well above the 2018-H1 low of €0.1748/kWh by €0.0813/kWh, or roughly 46.5% (tariff_history).

For households comparing a heat pump against simpler assumptions, that means two separate questions should not be conflated. The first is whether French electricity is cheap relative to gas; today it is not especially cheap on that measure, as the 1.78 ratio shows (price_ratio). The second is whether time-of-use optimisation can still shave meaningful cost off a heat pump’s running bill. That is where the day–night spread matters.

For broader context, our France country profile, 32-country comparison dashboard, and payback calculator all point to the same practical issue: tariff structure can matter almost as much as tariff level when buyers assume a single flat price.

How wide is the day–night gap, and has it narrowed?

The corpus does not contain France-specific household day and night electricity tariff levels, so it cannot directly quantify today’s day-versus-night spread in €/kWh or percent, nor can it show a Eurostat semi-annual history of French day and night tariffs separately. The available French electricity history is a single household tariff series for band KWH2500-4999, not a split peak/off-peak series (tariff_history).

What the series does show is that France’s all-in electricity price climbed from €0.1748/kWh in 2018-H1 to a high of €0.2926/kWh in 2024-H2, before easing to €0.2561/kWh in 2025-H2 (tariff_history). Across the full 16-semester history, the latest price remains the fourth-highest point in the series, behind only 2023-H2 (€0.2591/kWh), 2024-H1 (€0.2847/kWh) and 2024-H2 (€0.2926/kWh) (tariff_history).

So the evidence for this article’s angle is necessarily indirect. France may still offer a meaningful off-peak advantage in retail practice, but the corpus here cannot test that directly. What it can test is whether using a flat-rate electricity assumption around €0.2561/kWh materially changes heat-pump economics, and how sensitive that is likely to be if part of demand can be shifted below that average.

If you want the wider product backdrop, the market index snapshot puts the average listed heat-pump SCOP at 4.55, and the top SCOP air-to-water leaderboard shows how far the best-performing units sit above the market average (market_index_snapshot).

What the spread means for heat-pump running costs

Using the corpus only, a representative way to frame annual running cost is to start from the market-wide average SCOP of 4.55 and a household annual space-heating demand assumption. The corpus does not provide a standard French heat-demand figure, so any such demand assumption is external and cannot be cited from the dataset. What can be said with numbers is the cost per delivered kWh of heat.

At France’s current electricity tariff of €0.2561/kWh, a heat pump with SCOP 4.55 implies an electricity cost of about €0.0563 per delivered kWh of heat (0.2561 / 4.55) (country_profile) (market_index_snapshot). At the rough gas break-even rule for SCOP 4, the electricity-to-gas ratio would need to be around 3.7; France is at 1.78, less than half that level (price_ratio).

Against actual gas, the comparison is starker. France’s household gas tariff is €0.1436/kWh (country_profile). A simple ratio view therefore puts heat from a SCOP 4.55 pump at about 60.8% lower energy cost per delivered kWh than direct electric resistance heat, and also well below the retail gas tariff on a pure energy-input basis, though boiler efficiency is not provided in the corpus and should not be assumed here (country_profile) (market_index_snapshot).

What about full-day operation versus off-peak-shifted operation? The corpus cannot answer that with a French euro figure because it does not include French day and night prices or a load-shift share. Without those two inputs, any annual savings estimate would be speculative. The right way to read the present data is narrower: a flat-rate assumption of €0.2561/kWh is a valid baseline, but not a test of tariff-optimised operation (country_profile).

Readers comparing real machines can use the full heat-pump catalog, the filtered air-to-water heat-pump catalog, and the methodology page to see how SCOP feeds into cost comparisons.

France versus the rest of Europe on power, gas and subsidy support

France sits in the lower half of Europe on the electricity-to-gas ratio ranking: at 1.78, it is the fourth-lowest ratio among countries with both fuels reported, behind Sweden (1.3), Netherlands (1.49) and Portugal (1.73) (price_ratio). That is a notable divergence from markets such as Poland (3.71), Belgium (3.9), the United Kingdom (4.63) and Romania (5.11), where the retail price structure is much closer to or above the rough 3.7 threshold (price_ratio).

On electricity price alone, France at €0.2561/kWh sits close to peers such as the Netherlands (€0.2558/kWh) and below Germany (€0.3869/kWh), Belgium (€0.3499/kWh) and Austria (€0.3272/kWh) (country_compare). On gas, however, France’s €0.1436/kWh is high by European standards — above Germany (€0.1223/kWh), Belgium (€0.0898/kWh) and the Netherlands (€0.1719/kWh) only lower than the Dutch figure among those examples (country_compare).

Using the 29-country country_compare list with reported electricity prices, the median electricity tariff is €0.2558/kWh; France at €0.2561/kWh is therefore just €0.0003/kWh above the median, effectively in line with the middle of the pack (country_compare). For gas, the median across the 26 countries with reported values is €0.0898/kWh; France at €0.1436/kWh is €0.0538/kWh above that median, or about 59.9% higher (country_compare).

Subsidy support helps offset that weak ratio. France’s current maximum heat-pump subsidy in the corpus is €11,000 through MaPrimeRénov’, with support up to 90% of cost in the Bleu band and air-to-water grants from €3,000 to €5,000 depending on income band, while geothermal reaches €11,000 (country_profile). That is smaller than Austria’s €23,000 or Poland’s €31,000, but above Belgium’s €4,000, Italy’s €5,000 and Netherlands’ €2,750 maxima in the comparison table (country_compare).

When flexible operation still pays, and when flat-rate assumptions are close enough

The safe numeric takeaway is this: France’s core retail-electricity position is middling on electricity price but weak on electricity-to-gas ratio, with €0.2561/kWh power, €0.1436/kWh gas and a ratio of 1.78 (country_profile) (price_ratio). That makes efficiency and subsidy support more important than tariff arbitrage alone.

Where the article’s original question becomes harder is the off-peak angle. The corpus does not provide France’s current day tariff, night tariff, or historical day–night spread, so it cannot show how many years had a spread large enough to materially alter heat-pump economics versus a flat-rate assumption. Plainly: that part cannot be answered from the supplied data.

Still, the practical implication is clear enough. If a buyer, installer or journalist is using a single French household electricity price, €0.2561/kWh is the defensible baseline from the corpus (country_profile). But if the household will actually run a large share of heating, hot-water recovery or buffer charging in off-peak windows, a flat-rate assumption risks overstating annual running cost. How much it overstates it in France today is exactly the missing number.

That is why tariff-watch pieces need both sides of the ledger: the average price series from Eurostat and the retail time-of-use split. We have the first; we do not have the second in this dataset.
