Administrative simplification ahead. The housing grant, which was previously managed separately, is now integrated into the Klimabonus programme. Good news for property owners who will now have just one point of contact.
What Concretely Changes
Previously, property owners had to manage two separate applications: Klimabonus for energy renovation and the housing grant for other improvements.
Since 2025, everything is centralised on guichet.lu with a single file. Grants are calculated and paid together, which considerably simplifies procedures.
The Advantages of This Merger
This integration brings several concrete benefits.
A single file to compile means less paperwork and fewer risk of errors.
A single point of contact facilitates tracking applications and any follow-ups.
Reduced processing times thanks to centralisation allow faster payment of grants.
Better visibility of total grants helps plan your renovation budget.
Who Is Affected?
This simplification benefits all owner-occupiers carrying out renovation works in Luxembourg.
The eligibility criteria remain unchanged. Only the administrative procedure is simplified.
Advice: If you have an application in progress under the old system, it will be automatically transferred to the new scheme. No additional steps are necessary.
How to Benefit
To benefit from this simplification, simply submit your application on guichet.lu as for standard Klimabonus.
The form now integrates both types of grants. You simply tick the works concerned and the system automatically calculates the cumulable grants.
