Belgian Energy Prices Surge for 60% of Households in August
Energy prices for the month of August have been announced, and they are rising significantly for approximately 60% of Belgian households who hold variable-rate contracts. The increase, driven by escalating tensions in the Middle East, adds fresh pressure on families already grappling with rising inflation and economic uncertainty.
Rising Wholesale Prices
July proved to be a turbulent month for European energy markets. The conflict in the Middle East intensified, with a new sea strait blockade, threatening rhetoric from US President Donald Trump, and a violated ceasefire all pushing gas prices sharply upward. According to Het Laatste Nieuws, one megawatt-hour of natural gas on the TTF exchange cost €43 at the beginning of July but has since climbed to €57.
On 24 July, the European TTF gas price reached €63.14 per megawatt-hour — the highest level since early January 2023 and the highest since the outbreak of the US-Israel-Iran war. As VRT NWS reported, this marks the end of several months of relatively stable prices.
Impact on Household Bills
Energy suppliers are now passing these higher market prices on to consumers. Anyone signing a fixed-rate natural gas contract today pays €209 more per year than in July, while the impact on electricity is more limited at €64 more per year. A fixed natural gas tariff for new customers now costs 7.39 eurocents per kilowatt-hour, compared to 5.07 eurocents in March before the escalation of the Middle East conflict.
However, the rate increase is not only a blow for those seeking new fixed-rate contracts. Households with variable-rate contracts — accounting for approximately 60% of Belgian families — will automatically see the higher market prices reflected in their bills next month or next quarter. Those with existing fixed-rate contracts remain protected for the duration of their agreement.
Excise Duties Add to the Burden
Compounding the market-driven increases, excise duties on natural gas and heating oil rose on 1 August as part of the federal government’s multi-year budget. According to VRT NWS, the average gas-heated household will pay approximately €18.17 more per year in gas excise duties, while electricity excise duties decrease by €12.64 — a net increase of about €5.50 per year. The reform, driven by EU requirements to remove fiscal advantages for fossil fuels, will continue through 2029, with VAT on gas rising from 6% to 21% by January 2030.
Opposition party Anders has criticized the measure as a “sham,” arguing there is no real tax shift as long as the electricity bill does not decrease as much as the gas bill increases, as reported by VRT NWS.
Inflation Rising
Belgium’s inflation rate rose to 3.56% in July 2026, up from 3.4% in June, driven primarily by higher energy costs and transport prices, according to Business AM. The trend adds to concerns about the broader economic impact of the energy price surge.
Consumers Respond
The sharp price increases have triggered a significant consumer response. Approximately 200,000 Flemish households have switched energy suppliers since the outbreak of the Iran war at the end of February — the highest number of switches since the 2022 energy crisis, as Simuleer.be reports. Smaller suppliers offering competitive fixed-rate contracts have gained market share, with EnergyVision reportedly attracting over 1,500 new customers per day at the peak.
A Perfect Storm for Winter
Looking ahead, European gas reserves are at dangerously low levels — almost as low as in the disaster year 2022. The EU’s target of 75-80% fill rate by 1 November appears to be a race against the clock. Energy expert Kris Voorspools, quoted by VRT NWS, advises: “Step away from natural gas and switch to (renewable) electricity.”
The geopolitical vulnerability is structural: Europe has traded its dependency on Russian gas for a dependency on American LNG, with the US now providing 27% of all gas imports and nearly 60% of LNG imports. President Trump has threatened to shut off the gas supply to Europe as leverage in trade negotiations.
What’s Next
With the Middle East conflict showing no signs of resolution and European storage levels critically low, energy prices are likely to remain elevated. For Belgian households, the advice from experts is clear: compare energy suppliers regularly, as price differences within both fixed and variable contract categories remain significant. Those with variable-rate contracts face the most immediate impact, while the broader economic consequences of rising energy costs are expected to ripple through inflation figures in the coming months.
