Energy performance certificate CPE

All property transactions in Luxembourg require the production of an Energy Performance Certificate. The CPE or passeport énergétique certifies the energy quality of a home.
When selling or renting out a property, the owner must provide the buyer with an energy passport proving the property’s energy performance.

The EPC calculates the energy performance of a building

The Energy Performance Certificate is more commonly known as an energy passport.

The EPC defines the energy consumption of a building or home. It is drawn up on several pages, according to very precise standards. The CPE determines 3 main elements:

  • energy performance class. It determines the primary energy consumption of the dwelling.
  • thermal insulation class. It corresponds to the home’s heating requirement index.
  • Energy performance class. It defines the building’s CO2 emissions.

Each classification is graded from A to I.

Grade A is the best class. It corresponds to passive houses. Class B is the rating given to low-energy homes. Class C corresponds to energy-efficient homes. Class I is the lowest class.

When is an EPC mandatory?

The Energy Performance Certificate is mandatory since the Grand-Ducal regulation of November 30, 2007. The CPE is valid for 10 years. It is passed down from owner to owner.

Older buildings

EPC is required for the sale, conversion, extension or construction of a home.

Even in the case of rental, the owner must provide the Energy Performance Certificate to his tenant.

However, in the event of renovation and improvement work, it is advisable to obtain a new passeport énergétique. In fact, energy performance will be affected by the work. A new EPC will be very useful in the event of resale of the property. The value of your property depends on it.

New buildings

Since 2017, all new buildings in Luxembourg have had to meet an AAA rating on all three energy consumption calculation elements.

EPC and property renovation

The PBS is for information purposes only. Regardless of the calculated energy performance of a building, there is no obligation to renovate the property to improve its energy performance.

Nevertheless, the Luxembourg government provides financial assistance for home renovation . These are specifically aimed at improving the energy performance of buildings.

Carry out an energy passport

The passeport énergétique is mandatory for all property sales and rentals. The owner must be able to provide it. The Energy Performance Certificate must be issued by professionals certified by the Luxembourg government.

You can evaluate the performance of your home using tools available on the web. However, these appraisals are not the official documents required for real estate transactions.

You’ll find a list of approved professionals on who can draw up an Energy Performance Certificate for your home.

Energy performance and rents

In 2022, the government has drawn up a bill to correlate rents with the energy performance of housing. The aim is to tackle the problem of “passive heating”. This law is still pending.

In practice, under the law, rents would be capped. This ceiling would be set according to the classification of the property and the investment made by the owner. In concrete terms, the tenant’s rent would be :

  • 3.5% maximum of the capital invested by the owner in homes with an EPC rating of A to E
  • 3.0% maximum of the capital invested by the owner in low-energy-performance homes (F to I rating)

As a reminder, the maximum rental amount is currently 5% of the capital invested. There is currently no such thing as energy performance.

Moreover, under this law, the amount of capital invested should also be indicated in the lease .
