Wallonia sets out renovation roadmap to make dwellings energy-neutral by 2050

On 11 December 2025, the Walloon Government approved a new policy framework aimed at significantly accelerating the energy renovation of residential buildings. By means of this initiative, Wallonia is seeking to implement the objectives of the Air Climate Energy Plan 2030 (PACE) and comply with the European Energy Performance of Buildings Directive (EPBD IV). The ultimate ambition is for every dwelling in Wallonia to achieve an EPB label with an A rating by 2050.

At this stage, the plan sets out a strategic framework that will still need to be translated into concrete legislation. The government has identified three key pillars: a binding renovation timetable, a phasing-out of polluting heating systems and enhanced support for citizens.

1. A binding renovation timetable

At the heart of the plan lies a renovation timetable requiring homeowners to progressively improve the energy performance of their property.

From 2028 onwards, anyone purchasing a dwelling will have a period of five years in which to achieve a specified EPB rating. In specific terms, this means:

  • EPB label D for properties purchased from 2028 onwards;
  • EPB label C from 2031 onwards;
  • EPB label B from 2036 onwards;
  • EPB label A from 2041 onwards.

Minimum standards will also be introduced for existing dwellings, though a longer transition period will apply:

  • EPB label F by 2031;
  • EPB label E by 2036;
  • EPB label D by 2041;
  • EPB label C by 2046;
  • EPB label B by 2050.

 

2. Decarbonisation

A second pillar focuses on phasing out oil-fired and coal-fired boilers. From 1 January 2026 onwards, such systems may no longer be installed in new buildings, whether residential or non-residential. One year later, from 1 January 2027 onwards, the same prohibition will apply to buildings undergoing major renovation.

In addition, from 2027 onwards, the installation of new oil-fired or coal-fired boilers will be banned in any building that can be connected to the natural gas grid. A complete ban on the installation of these systems will follow from 2031 onwards.

Financial support will be made available to vulnerable households to help them invest in sustainable alternatives, such as heat pumps or biomass boilers.

 

3. Local guidance and support for citizens

The third pillar provides that citizens will be able to receive technical and administrative guidance via local support desks to help them carry out their renovation projects.
