Belgian Households Can Save Up to €700 on Energy This Winter

Belgian consumers have a critical window of opportunity this summer to lock in significantly lower energy rates for the coming winter, with price differences between the cheapest and most expensive contracts reaching as high as €700 per year for gas and €450 per year for electricity, according to an analysis by price comparison platform Mijnenergie.be. Energy experts are urging households to compare supplier offers now rather than passively accepting contract renewals, as decisions made in July and August will directly determine heating costs during the 2026-2027 winter season.

Why Now Matters

While summer energy consumption is at its lowest — a typical Belgian household uses barely 1.68% of its annual gas in August — the contract chosen today will remain in effect for at least one year, covering the entire winter heating season. The temptation to delay the decision is strong, but the financial stakes are substantial.

Last August, over 66,000 Belgian households switched electricity suppliers and nearly 53,000 switched gas providers, making it the second-highest month for switching activity. Many of those households will soon receive contract renewal offers, and energy expert Jordi Van Paemel of Test Aankoop warns that simply accepting the renewal could mean missing out on hundreds of euros in savings.

The Geopolitical Context

The energy market landscape has shifted dramatically since early 2026. The US-Israeli military campaign against Iran that began in late February, and Iran’s subsequent blockade of the Strait of Hormuz, sent shockwaves through global energy markets. Gas prices spiked approximately 70% in March compared to February, while electricity prices rose by about 25%.

A ceasefire was reached on April 8, and a 14-point principled agreement between Iran and the US was announced in mid-June. Gas prices have since stabilized around €45 per megawatt-hour — still roughly 50% higher than pre-war levels of €30/MWh. However, as VRT NWS reported, the Strait of Hormuz remains effectively blocked pending formal signing of the agreement, and analysts expect it will take two to three months for oil and gas production to reach 70-80% of pre-war levels even after reopening.

Adding to the concern, European gas storage facilities are only about 40% full, compared to 49% a year earlier. High market prices are making it expensive to replenish reserves, and competition with Asian markets for liquefied natural gas (LNG) cargoes could further pressure prices.

Fixed vs. Variable: The Dilemma

Currently, variable-rate contracts are approximately 15% cheaper than fixed contracts on average — translating to savings of about €245 to €265 per year for a typical household. However, this discount comes with risk. If geopolitical tensions escalate further or winter is particularly cold, prices could spike again, making fixed contracts the wiser choice.

Professor Johan Albrecht, energy economics expert at Ghent University, told VRT NWS that prices are expected to remain at current levels — slightly declining but not spectacularly — for the foreseeable future. “It will certainly take several more months before we’re back at pre-war levels,” he said.

Van Paemel advises consumers who are uncertain to take a measured approach: “If you’re in doubt, you can wait and see for now. If the geopolitical situation escalates further and prices rise again, you can still choose a fixed rate.”

Welcome Bonuses Sweeten the Deal

Beyond the base rate differences, many suppliers are offering substantial welcome discounts for new customers — up to €900 in some cases. These promotions can significantly reduce costs for households willing to switch providers, though consumers should carefully review contract terms, including fixed fees that can reach €143 per connection if a contract is terminated early.

Regulatory Changes in 2026

Belgian federal excise taxes on electricity are decreasing while gas taxes are gradually increasing — part of a deliberate government policy to incentivize electrification. Network tariffs for electricity are also decreasing in Flanders, saving about €20 per year for a typical household consuming 3,500 kWh. Gas taxes are expected to rise by approximately €20 in 2026, increasing to €75 by 2029.

What to Watch For

The key question remains whether the US-Iran agreement will be formally signed and the Strait of Hormuz will actually reopen. Oil prices have shown continued volatility — rising above $90 per barrel again on July 20 after briefly falling below $80 in June — indicating that markets remain on edge.

For Belgian households, the message from all sources is consistent and urgent: compare energy offers now. The potential savings — up to €700 per year — are substantial enough to warrant immediate attention. Waiting until the cold weather arrives will mean paying the price for inaction.
