The reported figures do not provide one single nationwide household price for a kilowatt-hour of electricity or gas. They instead show several different price levels. European gas prices passed €65 per megawatt-hour on 20 August, briefly exceeded €80 on 9 September, and continued rising in September, according to La Libre and HLN. Those are wholesale-market benchmarks, not a complete household tariff.
A household bill can therefore rise even when the market figure being discussed is not itself a retail kWh price. HLN reported that the average Flemish household's electricity and natural-gas bill rose again in September. The same report said Flemish households were facing their highest energy costs in years.
Consumption is another reason that a kWh price does not by itself determine the final bill. An EPC can indicate a home's energy efficiency, but HLN reported that actual use also depends on residents' behaviour and multiple energy sources. For electric cars, 7sur7 reported that charging losses can reach 25%, meaning the electricity drawn can exceed the energy transferred to the battery.
The reporting identifies several influences on the amount a household pays: the supplier's contract, electricity or gas consumption, taxes and the handling of consumption data. From 1 August, the Federal Public Service Finance increased excise duties on natural gas and heating oil while reducing those on electricity, according to 7sur7. The change followed the programme law adopted by the House of Representatives at the end of May.
Social tariffs are a separate regulated element. 7sur7 reported on 14 September that the energy social tariffs would rise sharply from 1 October. The Commission for the Regulation of Electricity and Gas sets these tariffs quarterly, with new amounts published on its website and in the Belgian Official Gazette.
Billing can also depend on accurate meter data and clear supplier responsibility. La Libre reported that Ores was sanctioned by Cwape after failing to provide electricity-consumption data for certain customers. In September, HLN reported proposed rules under which a final bill could not cover energy consumed more than a year earlier, and bills from a supplier without a contract or for energy used by someone else would be excluded.
A fixed contract is presented as offering price certainty, but the recent Belgian consumer advice has repeatedly challenged the idea that it is automatically the safest option. HLN and 7sur7 reported in August that experts considered fixed electricity and gas contracts riskier than many consumers assumed. Their analyses also noted that people who chose a fixed rate in the past were sometimes better off.
The central trade-off is timing. A consumer who fixes a price avoids some exposure to later movements, but can also be tied to a choice made before prices fall or before a different tariff becomes more attractive. The August analyses compared contract selection to darts or the game of vogelpik, stressing that the result depends on how prices subsequently develop.
Variable tariffs can move with market conditions, making contract reviews particularly relevant when gas prices rise. On 27 August, 7sur7 advised consumers to check their contract before a possible tariff increase on 1 September. The report linked that risk to the recent rise in natural-gas prices, while September reporting recorded further increases in household electricity and gas bills.
The period was marked by renewed upward pressure, especially in gas. On 20 August, La Libre reported that European natural-gas prices had exceeded €65 per megawatt-hour, their highest level in five months. On 9 September, HLN reported a brief move above €80 per megawatt-hour, the first such breach since January 2023. La Libre said on 10 September that European gas prices had continued rising and had more than doubled since the start of the war it described.
Several factors were cited in the coverage. La Libre linked late-August price pressure to lower European gas reserves ahead of winter and renewed tensions in the Middle East. Its September report referred to the conflict between the United States and Iran over the Strait of Hormuz. HLN also reported that oil and gas prices rose amid new threats from Donald Trump.
The impact reached household budgets. La Libre reported that inflation accelerated to nearly 4% in August, with the largest increases in natural gas, fuel, clothing, electricity and heating oil. HLN subsequently reported another rise in the average Flemish household's electricity and gas bill in September. Energy companies also challenged more than €1 billion in Belgian windfall-profit taxes in legal cases, according to HLN and 7sur7.
The clearest household-price evidence in this period concerns Flanders. HLN reported that 84% of Flemish homes, apartments and small businesses had a digital energy meter, with Fluvius appearing on track for a full rollout by 2029. Another HLN report said that 12% of Flemish households chose their supplier through a group purchase, using collective bargaining power even when market prices were high.
Flanders also saw several grid and billing developments. About 10,000 households in the Flemish Ardennes lost power after an Elia high-voltage substation failed on 22 August, according to VRT NWS. Thousands of households in North Limburg and Haspengouw also experienced outages in September after medium- or high-voltage substation faults. In Lanaken, Nelissen Brickworks warned that a saturated electricity grid was hampering a €10 million decarbonisation investment, VRT NWS reported.
Wallonia appears in the period's reporting through its regulator and network operator. La Libre reported that Cwape sanctioned Ores over missing consumption data for certain electricity customers. The reporting also covered higher TEC fares in Wallonia, but that is a public-transport charge rather than a household electricity or gas tariff. The cited announcements provide no comparable Brussels household-price figure.
Comparing contracts is especially relevant when market prices and household bills are moving in different directions. HLN reported that 120,000 Belgian households changed their energy contract in August 2022, despite lower summer consumption, and presented comparison as a reason to review supplier choices. On 8 September, HLN reported that 12% of Flemish households used a group purchase, although rising gas prices could affect the terms and benefits.
Consumers should distinguish a supplier change from a billing or contract error. HLN described a case in which a customer believed he had switched to Luminus but continued receiving gas bills from Eneco; the dispute reached the justice of the peace. New rules proposed by Consumer Protection Minister Rob Beenders were intended to exclude bills from a supplier without a contract and bills for energy used by someone else.
A comparison should also account for the contract type and not only the advertised price. August analyses by HLN and 7sur7 warned that a fixed rate can look reassuring while carrying significant risks. Before choosing, consumers can check whether the offer is fixed or variable, how the bill is supported by meter data, and whether a group purchase really improves the terms for their situation.
The reported figures do not give one nationwide household kWh price. They show European wholesale gas benchmarks instead: above €65 per megawatt-hour on 20 August and briefly above €80 on 9 September. Household bills also reflect the contract, consumption, taxes, meter data and other charges. HLN reported that the average Flemish household's electricity and gas bill rose again in September.
Several developments coincided. European gas prices rose sharply in August and September, with HLN reporting a temporary move above €80 per megawatt-hour on 9 September. La Libre linked the increase to lower European reserves and geopolitical tensions. HLN then reported that the average Flemish household's electricity and natural-gas bill rose again in September.
Not necessarily. August analyses reported by HLN and 7sur7 said fixed electricity and gas contracts can carry significant risks despite their apparent certainty. Consumers who fixed their rate in the past were sometimes better off, but the outcome depended on later price movements. The coverage presents a fixed contract as a choice involving timing, not as a guaranteed saving.
The Commission for the Regulation of Electricity and Gas sets social tariffs every quarter. 7sur7 reported on 14 September that the tariffs would rise sharply from 1 October. The new amounts are published on the Creg website and in the Belgian Official Gazette according to the scheduled timetable.
A digital meter does not automatically mean a lower bill. HLN reported that 84% of Flemish homes, apartments and small businesses had one, while an investigation examined its impact on bills at current rates. Actual energy use also depends on behaviour and multiple energy sources, so the meter itself is not the only factor determining what a household pays.
Comparison can be worthwhile, particularly when tariffs are changing. HLN reported that 120,000 Belgian households changed contracts in August 2022 and that 12% of Flemish households used group purchases. Consumers should compare the contract type and terms, not just the headline price. A supplier switch can also create billing confusion, as shown by a dispute involving Luminus and Eneco.
