The Brussels-Capital Region, which is still being fuelled with lean gas, will soon be converted to rich gas. All Brussels households and companies will be affected by this conversion and in due course will have to take the necessary steps to prepare their appliances to run on rich gas.

See the federal government website for more information.

What is my conversion year?

  • The conversion works will be spread over a period of approximately three years, between 2020 and 2022.
  • The Brussels-Capital Region has been divided into three zones (see the map below).
  • At the beginning of summer each year (June), one zone will be converted to rich gas. However, in 2020, due to the disruption caused by the coronavirus, the conversion will exceptionally take place in 2022.

When and how will I be informed ?

  • Your network administrator (Sibelga) will inform you officially, 24 months before the actual conversion date of your zone, at the latest. You will be informed by letter or email.
  • You will receive a reminder at least 3 months before the conversion.
  • You will also be informed by your gas supplier.

What do I need to do?

  • You must have your gas appliances checked for compatibility.
    It is important to have this compatibility check carried out so that you can be sure that your appliances will work correctly and completely safely after the conversion. More info

  • Who can carry out this check? Only an authorised technician.
    As a reminder, this can be:
  • Which appliances are affected? Any appliances that run on natural gas.
    For example:
    • boilers
    • small and large water heaters
    • cookers and hot plates
    • stoves
    • heaters
    • decorative open fires

The compatibility check is provided during the boiler/water-heater's mandatory periodic inspection. Regional legislation requires your boiler to be checked every two years.

For information:
An allowance is provided to help certain households to perform this inspection. Please check whether you are eligible.

To summarise,

follow these 3 steps:


Have the gas compatibility of all my devices checked by an authorised technician.


Your appliance is compatible.

This is the case for all appliances
sold in Belgium since 1978

If necessary, the authorised technician adjusts the device.

About 20% of compatible appliances will need to be adjusted and this has to be done by an authorised technician.


The appliance is not compatible :

- either it is dated before 1978
- or you puchased it abroad and it does not comply
with the legal requirements in force in Belgium.

The device must be replaced.

The new appliances you get are more efficient and will reduce your energy use by around 25%.
