Household energy prices have risen across European capitals ahead of winter, although electricity and gas bills have increased more slowly than petrol and diesel costs. The latest comparison shows Brussels with the highest residential electricity price in euro terms, while Stockholm is the most expensive capital for household gas.
The figures, based on September 2026 data from the Household Energy Price Index, offer a snapshot of unit prices rather than complete household bills. Actual costs will also depend on consumption, contracts, taxes, government support and the heating needs of each home.
European energy prices have risen ahead of winter
Wholesale gas prices have climbed sharply, with Dutch TTF futures reaching €87.20 per megawatt-hour on 13 October 2026. That was substantially higher than the roughly €32 level recorded before tensions in the Middle East escalated.
Disruption to shipping through the Strait of Hormuz has added to concerns about global energy supplies. The route is an important corridor for liquefied natural gas, and market pressure has increased as Europe enters the colder months with lower storage levels than usual.
However, wholesale movements have not yet passed fully through to household tariffs. Between 2 February and 1 September 2026, average residential gas prices, including taxes, rose by 12% across the European capitals covered. Electricity prices increased by 4.2% over the same period.
By comparison, average consumer diesel prices in the European Union rose by 35% between 23 February and 5 October, while petrol prices increased by 23%, according to the EU Weekly Oil Bulletin.
Brussels records Europe’s highest electricity price
In early September, residential electricity prices ranged from 8.4 euro cents per kilowatt-hour in Kyiv to 41.3 cents in Brussels. The average across the EU capitals in the comparison was 27.2 cents per kilowatt-hour.
The five most expensive capitals in euro terms were:
- Brussels: 41.3 c€/kWh
- Berlin: 39.6 c€/kWh
- Dublin: 38.7 c€/kWh
- Bern: 38.6 c€/kWh
- London: 38.3 c€/kWh
Rome, Vienna and Prague also recorded prices above 34 cents per kilowatt-hour. Madrid and Paris were less expensive than those capitals but remained above the EU capital average.
At the lower end of the ranking, Budapest recorded 10.3 cents per kilowatt-hour, followed by Podgorica at 11.3 cents, Belgrade at 11.6 cents and Valletta at 12.3 cents.
Purchasing power changes the comparison
Nominal prices do not show how affordable energy is for households in different countries. When the figures are adjusted using purchasing power standards, Bucharest becomes the most expensive capital for electricity at 55.1 PPS, while Oslo becomes the least expensive at 11.5 PPS.
Among the capitals of Europe’s five largest economies, Rome ranked highest in purchasing-power terms, followed by Berlin and Madrid. Paris was the least expensive of the group after adjustment, although the comparison still reflects energy affordability rather than the total amount paid by an individual household.
Stockholm has the highest household gas price
Natural gas prices showed a different pattern. In euro terms, the highest residential gas price was recorded in Stockholm at 34.8 euro cents per kilowatt-hour. Amsterdam followed at 21.2 cents, making the Swedish capital a clear outlier.
The average across the EU capitals was 11.9 cents per kilowatt-hour. Kyiv recorded the lowest figure in the comparison at 1.5 cents.
Among the five largest European economies, Paris had the highest household gas price at 15.7 cents per kilowatt-hour. Rome followed at 15.2 cents, while Berlin stood at 12.5 cents. Madrid and London were lower, at 10.1 and 10.3 cents respectively.
After adjusting for purchasing power, Stockholm remained the most expensive capital for gas at 28.5 PPS. Budapest was the least expensive at 3.6 PPS. Lisbon, Amsterdam, Rome and Sofia completed the five highest rankings under this measure.
Electricity and gas costs do not always move together
The comparison highlights how national energy systems, taxes, market structures and household tariffs can produce different results for electricity and gas.
- Stockholm and Amsterdam combine relatively low or mid-range electricity prices with particularly high gas prices.
- Bucharest, Brussels and London have high electricity prices but comparatively lower gas prices.
- Sofia moves sharply higher in the gas ranking when purchasing power is taken into account.
- Dublin and Brussels fall 10 places each after purchasing-power adjustment, suggesting that their nominal prices look less burdensome relative to household purchasing power than the unadjusted ranking indicates.
These differences mean that there is no single European pattern for energy affordability. The impact on a household depends on whether it relies mainly on electricity, gas or another heating source.
Which capitals saw the biggest price changes?
Electricity prices rose most sharply in Lisbon between February and September 2026, increasing by 22%. Amsterdam followed with a 17.3% rise, while Madrid and Rome recorded increases of 15.1% and 14.9% respectively.
Luxembourg City recorded the largest fall in electricity prices, down 15.3%. Tallinn and Helsinki also saw declines.
Gas prices increased most strongly in Tallinn, rising by 59.2% from 7.8 to 12.4 cents per kilowatt-hour. Increases of more than 20% were also recorded in Brussels, Athens, Bern, London, Riga, Vienna, Paris and Berlin.
What could winter mean for household bills?
The September figures may not capture the full effect of the latest wholesale gas surge. Fixed-rate contracts can delay changes, while government assistance may reduce or postpone the effect on consumers. Conversely, households renewing contracts or using more energy during a cold spell could face higher costs.
Gas prices can also influence electricity prices where gas-fired power stations are used to generate electricity. The eventual impact will therefore depend on wholesale markets, national tariffs, storage levels, weather and policy support.
EU gas storage facilities were 72.4% full on 3 October, according to the Institute for Energy Economics and Financial Analysis. That was the lowest level recorded for that point in the year since records began in 2011, leaving the region with a smaller buffer if temperatures fall sharply late in the winter.
What the figures mean for Ireland
Dublin was among the most expensive capitals for electricity in euro terms, at 38.7 cents per kilowatt-hour. Ireland’s position in the comparison should not be interpreted as a complete measure of household energy affordability, because bills also depend on usage, standing charges, contract type and income.
For Irish households, the main issue over the coming winter will be how quickly wholesale market pressure feeds into retail tariffs. Customers on fixed contracts may see changes later than those on variable arrangements, while increased electricity demand during colder weather could raise total bills even if the unit price remains unchanged.
Conclusion
The latest European energy price comparison shows sharply different pressures across capitals: Brussels has the highest electricity price in euro terms, while Stockholm leads for household gas. With wholesale gas prices elevated and storage levels relatively low, winter bills will depend not only on national tariffs but also on contracts, support schemes, household consumption and weather. For Ireland, Dublin’s high electricity price underlines the importance of monitoring retail tariff changes as the heating season develops.
