Walloon adjustments regarding energy renovation

Wallonia: Stronger Momentum for Energy Renovation of Buildings

The Walloon Parliament and the regional government have recently confirmed important adjustments to the regulatory framework and support measures for energy renovation of buildings, in line with the objectives of the Air, Climate and Energy Plan (PACE).

1. Postponement of Renovation Obligations Upon Sale

One of the key measures adopted this week concerns the postponement of the energy renovation obligation linked to property sales.

Initially scheduled to enter into force on 1 July 2026, the obligation requiring buyers to improve the energy performance (EPB/PEB) of a property has been postponed until 2028.

In practical terms:

• From 2028, any buyer will be required, within five years of signing the notarial deed, to carry out renovation works to reach at least an energy label D.

• Further progressive targets are planned:

  • 2031 → label C

  • 2036 → label B

  • 2041 → label A

This roadmap reflects the Walloon Region’s ambition to significantly reduce the energy consumption of its building stock.

2. Reform of Renovation Incentives: Towards a More Structured System

At the same time, the Walloon government has confirmed its intention to thoroughly reform renovation support schemes.

The objective is to establish a more predictable, simpler and more efficient framework, while taking into account budgetary constraints and European obligations.

The main pillars of this reform include:

• Improved guidance and support for households throughout the renovation process;

• Better coordination of financial incentives, including low-interest or zero-interest loans (such as Rénopack and Rénoprêt), tailored to household financial capacity;

• Administrative simplification and the development of digital tools to facilitate access to aid;

• Clear long-term planning, offering greater visibility and certainty for homeowners and professionals in the construction sector.

3. Evolution of the EPB System: Progressive Obligations

The reform also introduces progressive energy performance requirements, with a clear goal: phasing out the most energy-inefficient buildings in Wallonia.

Minimum energy performance levels for existing residential buildings are expected to follow this timeline:

• Minimum label F by 2031

• Minimum label E by 2036

• Minimum label D by 2041

• Minimum label C by 2046

• Minimum label B by 2050

This gradual approach is designed to allow owners to anticipate renovation works and spread investments over time.

4. What Does This Mean for Owners and Buyers?

For property owners, these measures imply:

• The need to anticipate renovation works to remain compliant with future energy standards;

• A shift in renovation support, with greater emphasis on structured financing tools rather than direct subsidies alone.

For buyers, the message is clear: although postponed, from 2028 onward, purchasing a property will entail a formal commitment to carry out significant energy improvements within five years of acquisition.

Conclusion

The latest measures adopted by the Walloon Parliament and government lay the groundwork for a more sustainable and energy-efficient building stock. While certain obligations have been delayed, the overall direction remains unchanged. For property owners and investors, anticipating these developments will be key to preserving property value and meeting future energy performance standards.
