Klimabonus in Luxembourg

What is the Klimabonus in Luxembourg?

The Klimabonus is the financial aid program of the Luxembourg government aimed at supporting energy renovation work in existing homes.

Its objectives are twofold:

• Reduce the energy consumption of residential buildings
• Decrease CO₂ emissions
• Improve the thermal comfort of residents
• Durably enhance the real estate heritage

This program is primarily aimed at owners of single-family homes and apartments located in Luxembourg.

It can cover a significant portion of the cost of the work, especially when it is part of a coherent and efficient energy renovation.

What works are eligible for the Klimabonus?

The Klimabonus exclusively concerns works that have a direct impact on the energy performance of the housing.

Thermal insulation

Insulation often constitutes the first step in an effective energy renovation. The areas concerned include:

• Insulation of exterior walls (from the inside or outside)
• Insulation of the roof or attic
• Insulation of ground floors
• Insulation of facades
• Replacement of windows and exterior doors with high-performance joinery

Good insulation significantly reduces heat loss and improves the energy rating of the property.

Replacement of the heating system

The Klimabonus also supports the installation of more efficient and less polluting heating systems, such as:

• Air-water or geothermal heat pumps
• Biomass boiler
• Connection to a district heating network
• High-performance hybrid systems

The goal is to gradually phase out fossil fuels in favor of renewable solutions or high energy efficiency.

Installation of renewable energies

Equipment utilizing renewable energies is also supported:

• Photovoltaic panels
• Solar thermal systems
• Thermodynamic water heater
• Combined electricity production and heating solutions

These installations help reduce your energy dependence while benefiting from substantial aid.

Controlled ventilation

Improving the airtightness of the building must be accompanied by an efficient ventilation system.

The implementation of a controlled mechanical ventilation (CMV) double flow system may also be eligible for aid, subject to technical conditions.

What is the amount of the Klimabonus aid?

The amount of the Klimabonus depends on several factors:

• The nature of the work
• The energy performance achieved
• The areas concerned
• The compliance with imposed technical criteria
• The completion of a prior energy audit

In some cases, the aid can cover up to more than 50% of eligible costs, particularly within the framework of a coherent overall renovation.

The higher the energy performance, the greater the level of aid can be.

At Avenir Rénovations Luxembourg, we provide an accurate estimate of the available aid before the start of the work.

Eligibility conditions for the Klimabonus

To benefit from the Klimabonus, several conditions must be met:

Housing concerned

• The property must be located in Luxembourg
• It must have been completed for several years (generally more than 10 years for certain aids)
• It must be intended for residential use

Compliance with technical criteria

Each type of work must meet a minimum performance level.

For example:

• Maximum U-value for insulation
• Minimum efficiency for heating systems
• Certification of installed equipment

It is essential to engage qualified professionals to ensure compliance with the work.

Application before the start of work

An essential point: the application for aid must be submitted before the commencement of work.

Starting a project without prior validation may jeopardize the grant's approval.

This is why professional support is highly recommended.

The importance of the energy audit

In many cases, an energy consultation or energy audit is required to fully benefit from the Klimabonus.

This audit allows:

• Identifying the energy weaknesses of the building
• Prioritizing the work
• Estimating potential savings
• Maximizing financial aids

A specific aid is also provided to finance this audit.

At Avenir Rénovations Luxembourg, we coordinate this strategic step to optimize your project from its conception.

Why integrate the Klimabonus into a comprehensive renovation?

A coherent energy renovation offers several advantages:

Improvement of thermal comfort

You reduce temperature fluctuations and eliminate the sensation of cold walls.

Reduction of energy bills

A better-insulated house equipped with efficient heating consumes significantly less energy.

Property value enhancement

A property classified as energy efficient sells more easily and at a better price on the Luxembourg market.

Compliance with future regulatory requirements

Energy standards are regularly evolving. Anticipating these changes protects your long-term investment.
