How are Luxembourg residents approaching the energy retrofitting of their homes?

In February 2025, BNP Paribas, in collaboration with the Toluna - Harris Interactive institute, conducted a survey of 11,700 European residents, including 700 in Luxembourg, to better understand their perceptions regarding the challenges of energy retrofitting their homes.

In particular, the survey revealed that residents of the Grand Duchy are increasingly aware of the importance of energy efficiency in enhancing the value of their property.

The survey's findings also indicate that financial and technical support is becoming a key factor in removing certain barriers and accelerating the transition.

Renovating your home: a question of wealth

Luxembourg residents place protecting their homes at the top of their list of priorities when it comes to tackling climate change.

  • 80% (compared to 70% in Europe on average) think that energy performance directly influences the price of a house.
  • 66% consider it essential to invest to avoid reselling below market value.

Households have realised that properties with a poor energy rating lose value, making them difficult to sell or rent. Renovating your home is more than just an environmental commitment; it also helps to preserve and grow your wealth.

Luxembourg residents feel relatively unconcerned about climate risks

While the wealth aspect is well ingrained in the mindset of residents, climate concerns appear to be less pronounced:

  • 44% of Luxembourg residents say they are not concerned about climate issues related to housing, compared with 34% in Europe on average.

Luxembourg thus ranks alongside Germany and the United Kingdom as one of the countries least concerned about climate risks affecting housing. This perception can be explained by the fact that the impacts are less noticeable in the Grand Duchy than they are in regions that are more prone to issues exacerbated by climate change – such as wildfires, for example.

What are the main barriers to energy renovation?

The survey highlights that respondents from Luxembourg are largely convinced that the energy performance of homes is a key issue in the ecological transition of our society.

Nevertheless, certain factors prevent them from starting energy retrofitting work.

  • Firstly, 62% of respondents felt that energy performance regulations change too often.
  • Likewise, the majority struggled to identify work which would allow them to significantly improve their home’s energy performance.
  • They believe that the available subsidies are insufficient and that the savings generated would not be enough to make the investment worthwhile.
  • Finally, even if access to information is perceived as being easier in Luxembourg than elsewhere, 69% of respondents stated that they were unable to identify trustworthy companies to carry out their energy retrofitting work.

Debunking preconceived notions regarding energy renovation

Renovation projects are also held back by certain beliefs that, while sometimes inaccurate, still very much play a role in the thinking of many survey respondents.

Certified tradespeople are a mandatory requirement.
77% believe that the use of certified tradespeople to carry out work is obligatory.


False. Certification represents a guarantee of quality, but it is not a legal requirement.

It is only worth undertaking large-scale projects.
60% believe that several major renovations must be carried out simultaneously in order to achieve results.


False. You do not need to completely overhaul the external insulation of your home or replace all of your windows. Something as simple as insulating the attic or replacing a boiler with a heat pump, for example, can significantly improve a home's energy performance.

It is better to buy an energy-efficient home than to renovate.
58% believe that it is better to buy a home that is already energy efficient than to renovate one that isn’t.


Not necessarily. Targeted renovations can be paid off in no time and will contribute to the value of an existing property.

Proving profitability

One of the major barriers to renovation work remains its (perceived) cost. Many households feel that the subsidies available are insufficient and that it takes a long time for the savings to offset the investment.

However, the combination of currently available government subsidies and the energy savings achieved through well-targeted renovation work significantly reduces the payback period of such investments.

Energy renovation is therefore not only a long-term investment – it is a decision that can be profitable in the short and medium term as well.

Greater trust in public institutions

It is interesting to note that Luxembourg's public institutions are seen as one of the main trusted partners when it comes to providing reliable advice and genuine support for energy renovation work, just behind specialist companies (although they do only rank fifth in Europe).

  • 73% believe that the public authorities are actively addressing housing and climate issues (compared with 55% in Europe).
  • 46% believe that it is primarily the responsibility of public authorities – ahead of businesses and citizens – to take action.
