Firstly, there is the financial aid for the renovation of old housing. This funding from the State may be obtained for certain works to improve the habitability, hygiene and safety of old housing. The following conditions are required for the grant of the subsidy.
You must live in the housing as your principal and permanent residence and not be the owner or usufructuary of another residence, whether in Luxembourg or abroad. The works must be performed in buildings that were first occupied more than 15 years ago or, in the event of increasing the building’s surface area, not exceed 140 m2 of useful residential surface for a single-family residence (120 m2 for an apartment). The surface area measurements do not include cellars, attics, garages or common areas in co-owned buildings. For buildings constructed prior to 10 September 1944, there is no surface area condition. Routine maintenance and embellishments do not qualify for the subsidy.
The subsidy will correspond to no more than 30% of the total amount paid for the renovation works and may not be greater than EUR 10,000 per beneficiary. In addition, the amount of the renovation subsidy is determined according to the income and family status. If, for example, your household is childless and your monthly accumulated income exceeds EUR 6,250, you are not entitled to the subsidy.
Financial aid from the State for the renovation of old housing may be combined with the additional grant for architect or consultant engineer fees capped at 1,250 EUR. You may also benefit from other aids, such as the financial aid for special home adaptations for persons with physical disabilities – 60% of the cost of works without exceeding EUR 15,000 – and financial aids for the promotion and rational use of energy and the development of renewable energy sources. The Ministry of Environment (Ministère de l’Environnement) grants subsidies called “PRIMe HOUSE” for energy efficiency enhancements in existing residential buildings and to cover the investment and installation costs of solar thermal or photovoltaic systems, heat pumps, wood-fuelled boilers and heating networks and connections.
