Will Flanders’ energy-bill overhaul really make most households better off?
The Flemish government has provisionally approved an energy-tax overhaul that it estimates will reduce total bills for roughly two-thirds to 70% of households from 2028, while raising costs for the remaining group, particularly heavy gas users.
For a standard household using gas and electricity, the government’s model produces an electricity saving of about €80 and a similar increase in the gas bill. Heat-pump households should gain more, while heavy gas users in inefficient homes may pay more. Contract choice, wholesale prices and federal charges can still outweigh the Flemish effect.
The provisionally approved an overhaul of household and business energy charges on 10 July, estimating that roughly two-thirds to 70% of households will pay less overall from 2028, while about 30% will face a higher bill. The plan transfers €317 million in energy-transition costs from electricity to fossil heating fuels and removes another €173 million from electricity charges through an accompanying tax cut, according to calculations reported by and .
For households, the decisive issue is not income alone but how a home is heated, insulated and powered. Under the government’s standard example, a household using both electricity and natural gas would save about €80 a year on electricity but pay approximately €80 more for gas. That makes the Flemish reform itself broadly neutral for this model household, before market prices and separate federal or European measures are counted.
The distribution changes sharply beyond that average. reported an estimated annual saving of €19 for an apartment household, €24 for a home heated with fuel oil and €148 for a household with a heat pump. People living in poorly insulated detached homes and consuming large volumes of gas are more likely to lose. Their additional charge could be materially larger than their electricity saving, while tenants may have little control over the heating system that determines the outcome.
Flemish Energy and Climate Minister Melissa Depraetere of Vooruit presents the package as a correction to a distorted price signal. Electricity currently costs a Flemish consumer about four times as much per kilowatt-hour as natural gas, even though electrifying heating is central to reducing emissions. The reform is expected to bring that ratio down to around 2.9. Ghent University energy expert Joannes Laveyne told that experience elsewhere in Europe suggests a ratio of approximately 2.1 to 2.4 would make heat pumps the consistently logical financial choice. The Flemish measure therefore improves the economics without necessarily settling every investment decision.
This distinction matters because a heat pump is a capital purchase, not an instant response to a higher monthly bill. Its cost and performance depend on insulation, radiator dimensions, required water temperature and the building’s heat loss. Owners of efficient homes can respond to the new price signal relatively readily. A household in an older property may first need expensive insulation work, while a tenant generally depends on the landlord. The reform rewards electrification most clearly where the ability to invest already exists.
The government’s mechanism combines a tax shift with a tax cut. From 2028, policy costs supporting renewable energy and efficient energy use will gradually move off electricity and onto natural gas, heating oil and other fossil heating fuels. Separately, expected proceeds associated with the EU’s second Emissions Trading System, , are intended to lower the net burden. The says the combined operation should remain budget-neutral for a household with average consumption, rather than simply generating additional regional revenue.
That promise has limits. directly controls only a relatively small portion of the final bill—about 11%, according to . Suppliers’ commodity prices, distribution and transmission tariffs, VAT and federal excise duties remain capable of overwhelming an €80 or €148 saving. The Flemish Nuts Regulator has previously shown how contract choice alone can produce larger differences: its 2024 price report found that an average household with a fixed contract paid €254 more for electricity and €375 more for gas than one with a variable contract. The reform changes the structure of the bill, not the volatility of wholesale energy markets.
Federal policy is moving in the same direction. An official Flemish overview says federal household excise duty on electricity is scheduled to fall from €49.41 per megawatt-hour to €38 by 2029, while the rate on natural gas rises from €9.23 to €13.60 per megawatt-hour. will add a carbon price to fuels used in buildings and road transport. These overlapping measures strengthen the incentive to leave fossil heating, but they also make it difficult to isolate what the Flemish decision will ultimately cost any particular household.
Small businesses face a similar split. Electricity-intensive firms stand to benefit, whereas bakeries, hospitality businesses and other small operators using substantial amounts of gas for heat or production may pay more unless they electrify. Larger energy-intensive installations in sectors such as steel, petrochemicals and power generation are expected to receive exemptions where current technology does not offer a practical substitute. That distinction will attract scrutiny from small-business organisations because firms with the least investment capacity may face the strongest immediate pressure.
The political divide is therefore about timing and fairness more than the basic need to electrify. Depraetere and governing-party representatives argue that continuing to load transition costs onto electricity discourages the very technologies climate policy requires. In the , PVDA, Vlaams Belang and Anders have challenged the use of an average household and warned that families unable to renovate could experience a tax increase rather than a neutral shift. N-VA parliamentarian Andries Gryffroy, whose party belongs to the governing coalition, has also cautioned that heat pumps in insufficiently insulated homes can be more expensive and place additional demands on the electricity grid.
The proposal is not yet the final bill that households will receive. The government gave the amending decree approval in principle, meaning advisory review, detailed implementing decisions and parliamentary treatment still matter. The central tests will be whether promised revenue is available in the assumed amounts, how vulnerable households and tenants are protected, which companies qualify for exemptions and whether the published impact models survive changes in consumption and market prices. Until those details are fixed, most Flemish families can treat the projected saving as a direction of travel—not money already secured.
Impact
Regional — The measure applies in Flanders and will influence household heating choices, renovation economics and operating costs for Flemish small businesses. It does not directly redesign energy charges in Brussels or Wallonia.
International — The reform is linked to ETS2, the European Union’s emissions-trading system for fuels used in buildings, road transport and additional sectors. Expected ETS2-related revenue is intended to help finance an additional reduction in Flemish electricity charges from 2028. That gives an EU climate instrument a direct connection to household energy bills in Flanders. The regional tax shift does not itself alter energy charges in Brussels or Wallonia, although residents across Belgium will encounter the wider EU carbon-pricing framework.
What it means for you
If you live in Flanders, compare your electricity and heating-fuel consumption before the planned 2028 start. Heat-pump households are modelled to save about €148 annually, while a standard gas-and-electricity household may see roughly €80 disappear from electricity costs and reappear on the gas bill. Heavy gas users, particularly in inefficient homes, face the greatest risk of paying more. Apartment and oil-heated households are modelled to save €19 and €24 respectively. When evaluating renovation or heating-system choices, also compare contracts and wholesale-price exposure because these can outweigh the regional change.
Opposing perspectives
- Flemish government and electrification advocates
Minister Melissa Depraetere and governing-party supporters argue that charging energy-transition costs mainly through electricity is economically inconsistent. Moving part of the burden to fossil heating should make heat pumps more attractive, reduce exposure to imported fuels and reward households that insulate or electrify.
- PVDA, Vlaams Belang and Anders opposition parties
Opposition representatives argue that budget neutrality for a model household conceals losses among families using substantial amounts of gas. They say many occupants of older homes cannot afford a heat pump or major renovation and could therefore pay more without having an accessible alternative.
- Small gas-dependent businesses
Bakeries, hospitality operators and other smaller firms using gas-fired processes may support cheaper electricity in principle but face higher near-term costs if electrification requires replacing expensive equipment. Their concern is sharpened if large industrial users receive exemptions unavailable to smaller competitors.
- Building and grid specialists
Energy specialists broadly recognise the need for a lower electricity-to-gas price ratio, while warning that 2.9 may still be too high to make heat pumps compelling in every building. Poor insulation, equipment prices and local grid capacity remain important constraints.
