Your electricity bill: understand and reduce it

Energy prices have collapsed since their peak, and yet your electricity bill barely moves. According to the CREG, the energy component accounts for only about 40 % of the bill. The rest — network costs, taxes, excise duties and VAT — is regulated or legislated, identical whoever your supplier is, and network costs can even rise as your consumption falls. Our block-by-block breakdown shows what you can still act on.

Of all the documents called “invoice”, only the annual statement, based on actual meter readings, tells you what you actually owe; instalments are merely advances calculated from an estimate. A royal decree imposes five identical sections on every supplier. If you disagree, write first to your supplier or your network operator, then refer the matter to the competent service: meter and network to the regional body, contract and price to the federal one. The line-by-line reading guide goes through every item.

To reduce it, order matters and the savings do not add up; our costed Walloon levers set out the condition for each one:

• first check your entitlement to the social tariff, automatic for most of those entitled — but increased-reimbursement status alone no longer qualifies;
• then compare your offer, the only truly negotiable block, on a public comparison tool (CompaCWaPE, CREG Scan);
• shift before you cut: in Wallonia, the middle of the day is now off-peak on the dual-rate tariff, and the optional Impact tariff rewards genuine shifting.

Energy sharing comes on top: a share of local output is allocated to you and billed at a price agreed between participants, without switching supplier or installing anything. It only acts on the energy component of the shared kilowatt-hours, with network costs and taxes still due. In Wallonia, only sharing within the same building earns an 80 % reduction on the proportional terms of the network tariff, and a household on the social tariff must give it up on the shared portion. Peer-to-peer sharing between neighbours, for its part, remains inoperative in Wallonia for lack of an implementing order. Also check your supplier’s possible fees: they can wipe out the gain on small volumes. Our regional test shows where sharing is available; OptimCE’s public register lists open operations.

In Wallonia, when the bill becomes unpayable, the CPAS is the counter for nearly all support, from MEBAR to the Social Heating Fund; only the federal social tariff applies automatically, and it covers only gas and electricity, not heating oil. Our overview of the support schemes explains who opens what. As for “green” offers, a guarantee of origin proves that a renewable megawatt-hour was produced, not that it was delivered to you. Calculated quarter-hour by quarter-hour by the network operator, sharing is the only verifiable “short circuit” in Belgian law, even though it proves time and place, not legal title: our analysis of green electricity compares the two kinds of proof. The guides below cover each point in detail.
