Summary
Do you want to apply for European funding within the framework of the CEF (Connecting Europe Facility)?
The CEF Transport programme is aimed at study and works projects on the river, rail or road infrastructures of the TEN-T Core Network and Comprehensive Network. This programme targets actions related to the objectives of decarbonisation and contribution to smart, resilient and sustainable mobility.
A REFLOW refers to the reuse of funds that were not used or not fully spent in previous projects, which can then be reallocated to new calls for proposals. Since this involves reallocating funds from the 2021–2027 programming period, the maximum duration of the funded actions is set at 31/12/2029 for studies and 31/12/2030 for works.

Wallonia is not the ruling body for this funding, but it can provide you with information on this subject, and support you with your application. To be eligible, applications must have the agreement of the Member States concerned.
Key points
- For trans-regional or cross-border projects (more than one region or country involved), the signature of the letter of support is the responsibility of the federal transport authority. In this case, you should contact your functional administration: FPS Mobility & Transport (
eufunding@mobilit.fgov.be ) - If the project is located in Flanders or in the Brussels-Capital Region, you should contact their respective administrations.

The role of the Walloon administration is to help project leaders with their application to obtain co-financing under the CEF - REFLOW 2026 programme.
In the framework of the creation of your CEF - REFLOW 2026 application file for a project on the territory of Wallonia, two essential documents are issued by the SPW:
- the Environmental Compliance File;
- the letter of support from the Member State (signed by the competent Minister).
There are several steps involved in obtaining these documents:
1. Notification of project intention to the administration
After reading the documents and the legal framework surrounding this funding programme (obligations related to European funding and required documents), project leaders are asked to notify the administration (
This notification of intent must be accompanied by a short presentation of the project.
2. Environmental Compliance File
The template for the Environmental Compliance File is
Projects involving physical interventions must demonstrate compliance with European environmental law. This compliance is verified through the Environmental Compliance File, which includes two certificates, one for Natura 2000 and one for water quality.
In this respect, the project leader must contact the competent authorities (see below) and explain how their project has no significant impact on a Natura 2000 area or on water quality.
- Regarding Natura 2000:
The certificate is issued by the
- Regarding water quality:
The certificate is issued by the
The Environmental Compliance File must be sent to the competent services at the latest on 25/08/2026.
3. Evaluation by the administration of the project description note
The administration's evaluation of the project is based on a detailed presentation of the submitted project (concept note). It is important that this description note be submitted in its most complete form and include the following information:
- project description and technical specifications;
- location and schedule of the proposed action;
- estimated budget.
This note must reach the administration (
The deadline for the administration to evaluate the project is five working days. During this evaluation, the administration will check whether the project is in line with the regional mobility strategy and that it is not in competition with other Walloon initiatives.
4. The letter of support from the Member State
After evaluation of the competent administration services, the Minister decides on the appropriateness of a
The Minister's final approval will be sent to the project leader at the latest one week before the closure of the call for projects.
