Your gas bill is made up of a number of components. Part of your bill goes to cover Sibelga's distribution costs. We ensure that gas reach you every day via a network of thousands of kilometres of pipes.
The components of your gas bill
Figures based on the latest price observatory data published by Brugel 2025/08.
Simulation for a median Brussels customer representing an annual gas consumption of 12,728 kWh.
The energy cost (60% of the bill)
This is the price that the energy supplier charges. This price can, of course, vary depending on the energy supplier and the formula that you choose.
Your energy supplier is the one with whom you have concluded a contract, and from whom you receive your energy bill.
The distribution cost (20% of the bill)
The distribution cost included in your bill covers not only the actual distribution cost, but also other costs that Sibelga has to collect and pass on to the relevant parties.
1. Sibelga’s tasks (17,8%)
- Management, maintenance and development of the gas network, which spans over 2,900 km.
- Management of more than 500,000 gas meters.
- Management of consumption data.
- Management of the operation of the market (customer exchanges, supplier exchanges, etc.).
2. Municipal fee (1,8%)
The fee for occupation of the public domain is a levy paid by Sibelga to be able to use the public highway to lay gas pipelines.
3. Public Service Obligations (0,8%)
By order of the regional authorities, Sibelga also has to provide specific public services:
- Protecting vulnerable users by supplying energy to people with ‘protected customer’ status.
- Risk prevention for indoor gas installations.
VAT and other contributions (17% of the bill)
Federal contribution (10%)
This contribution finances the operating costs of the federal regulator of the gas and electricity markets (CREG), the decommissioning of nuclear power plants and the federal policy on reducing greenhouse gases.
A portion is also allocated to cover the costs of supplying energy to customers who benefit from the social tariff.
VAT (6%)
The VAT rate on electricity is set at 6% for residential customers. For business customers, the standard VAT rate of 21% applies.
Regional contribution (1%)
The regional contribution finances regional policy on rational energy use, in particular energy subsidies and the operating costs of the Brussels regulator, Brugel.
Transmission cost (2% of the bill)
The transmission cost covers the infrastructure costs associated with transporting gas from its place of production to the Brussels distribution network.
Unlike electricity bills, transport costs are included in the price of the energy consumed as billed by the supplier.
These costs are paid to Fluxys.
