Update in progress
Last updated more than 5 years ago
Work on construction sites is generally prohibited during night time hours inside built-up areas.
However, businesses who want to continue working at night can submit a written application to the Unit for Permits and Subsidies / Operating Permits Department (Unité permis et subsides / Groupe Autorisations d'exploitations) of the Environment Agency prior to starting the night work.
Who is concerned
Any business involved in works on construction sites, on repair yards, on storage sites or in development works or earthworks, public or private, between 22.00 and 7.00 inside built-up areas must apply for an exemption for night time works.
The application for the exemption may be submitted by the business itself or through a third party.
In order to prepare the application for night time works, it is recommended to prepare a topographical map which clearly indicates the contours of the work site as well as the location of the main noise sources (excavators, trucks, etc.). The map must also indicate the existing plots of land within a 200 m radius of the work site.
Depending on the size of the works, the Environment Agency may request that specific studies (e.g. acoustic impact assessment) are carried out in order to evaluate whether the exemption can be granted or not.
Applicants may contact the Environment Agency in order to clarify whether such studies must be attached to the application.
DeadlinesThe Environment Agency recommends submitting the application:
- for smaller on-site works, at least 2 weeks prior to the beginning of the works;
- for large scale works or works which include substantial noise levels and which must be carried out at night, at least 2 months prior to the beginning of the works (e.g. works which cannot be completed in one night, civil engineering works or works requiring the use of pneumatic drills or chainsaws).
How to proceed
Filing an application
Applicants have to submit a application for night work to the Unit for Permits and Subsidies / Operating Permits Department at the Environment Agency.
The document must state:
- the identity of the applicant;
- the identity of the business carrying out the works on site (if different from the applicant);
- a description of the site (address, name of the works owner, etc.);
- the reason why night work is necessary;
- a description of the works to be carried out, stating the start and end date of the works including the work hours;
- a description of the noise level with a listing of the equipment in use on the site;
- a description of the traffic on public roads generated by the work site.
- where required, the impact studies requested by the Environment Agency for large scale works.
Applicants must also join a topographical map indicating the work site limits, the location of the main noise sources and the plots of land within a 200 m radius of the site.
Following approval from the Environment Agency, the authorisation order will be issued.
The order must be displayed and available at all times on the work site. Moreover, the neighbourhood must be informed about the night works before the works begin.
In any case, the Environment Agency will inform the applicant about its decision by mail and/or email.
In the event of a refusal, applicants may submit a new application by offering to implement compensatory measures to reduce noise levels during night time (e.g. by putting up noise abatement walls, carry out acoustic impact assessments, etc.).
