Diff Prime: new online forms

Two new and simplified “Diff Prime” application forms for the areas of construction, renovation & renewable energies and for household appliances & electric vehicles are now online.

“Diff Prime” in brief:

  • Sustainable housing is supported by our municipality (25 % of the government subsidy).
  • E-bikes (“Pedelec25”) and bicycles will continue to be subsidized. This subsidy has been increased, but is linked to the state subsidy (50 % of the state subsidy).
  • The purchase of electrically powered light vehicles (e.g. moped, scooter, “Pedelec45”, motorbike, 125 cc, quad) are subsidized by the city of Differdange with 50 % of the state subsidy.
  • The “Diff Prime” for electric cars has been increased, but it is also linked to the premium from the state (municipality: 1000 €).

Practical information

All changes apply retroactively for 2020. Anyone who bought a bicycle at the beginning of last year and has received a state subsidy will also receive a subsidy from the municipality of Differdange. The only condition: At the time of purchase, the applicant must have lived here in the municipality.
