Carry out your procedure:

Who is concerned

Any private or public natural or legal person wishing to carry out technical assessment and inspection tasks requiring accreditation (e.g. a planning/engineering consultancy) must apply for specific accreditation.

Only accredited entities may carry out certain assessments/inspections, such as:

  • environmental impact assessments (EIA), environmental and energy audits, appraisals (e.g.: appraisal of waste management measures, impact assessments of a polluted site, etc.);
  • practices relating to the acceptance of works, technical audits, measurements and analyses (e.g.: acceptance of classified establishments, analyses of air quality, measurement of outputs, etc.);
  • verification of greenhouse gas emissions.


Applicants for accreditation must:

  • provide proof of sufficient technical or professional training, in the form of copies of diplomas and training certificates;
  • provide proof of satisfactory knowledge of the provisions relating to the technical tasks entrusted to them and of sufficient experience in carrying out these tasks (provide a document listing the laws, regulations, directives, circulars and standards which apply to the planned missions and also provide a list of recently carried out works in relation with the area of expertise in question)
  • have the necessary technical resources and staff to carry out the technical tasks required for the mission (provide a document describing the techniques and specific equipment used as well as the work methods used);
  • have the abilities required to draw up the certifications, minutes and reports constituting the materialisation of the assessments (provide at least one sample report per area of expertise concerned in French, German or Luxembourgish);
  • take out contractual and extra-contractual third-party liability insurance.

An applicant cannot be granted the accreditation if he:

  • is himself the designer, provider, developer or entrepreneur of the project subject to technical assessment or inspection;
  • is an authorised representative of the aforementioned persons.

The request for accreditation does not relieve from carrying out the other formalities regarding business permits.

Duration and deadlines

The competent authorities are not bound by time limits to process the request.

The accreditation is granted for a duration of one year. It may be renewed by submitting a request no later than 3 months before the expiry date of the accreditation.

How to proceed

Once the aforementioned conditions have been checked, the applicant may request one or more accreditations.

The application for accreditation must be sent to the competent authority depending on the area concerned, as defined in the table below.
