During the whole month of april 2023, the social inspection services will carry out national flash controls in the construction sector, including the electrotechnics and metal sectors.

A flash control is an announced control that is mainly informative and preventive in nature. This does not mean, however, that the inspection services will not make a report when serious and/or repeated offences have been committed.

See our tips below on how to best prepare for these announced controls.

Who is being targeted?

Violators of social regulations and unreported work are the target of this action.

The flash controls are part of the ‘action plan of the fight against social fraud’.

How to prepare?

In a question for an expert, we explain the employer's rights and obligations in the event of a social inspection.


The SIRS/SIOD checklist

The Belgian Service d'information et de recherche sociale/Sociale Inlichtingen- en Opsporingsdienst [Information and Social Research Department] has put together a specific check list for this sector. It contains the documents that are likely to be requested by the social inspector as well as the questions for which you can prepare. However, this checklist is only indicative in nature and does not prevent a social inspector from requesting that all documents required for his or her investigation are presented.


Here is a brief (non-exhaustive) overview of the main documents that we recommend you have at hand in the event of a company audit:

  • the employment regulations (containing all work schedules and proof of registration);
  • data with regard to the time worked and the remunerations of your employees (individual accounts, payslips, lists of work performances, proof of payment, etc.);
  • employment contracts (and, where applicable, appendices);
  • derogation documents or registration system for part-time workers;
  • proof of affiliation to O.P.O.C./P.D.O.K. (Belgian Employers’ Office for the Organisation and Control of Welfare Schemes), and be compliant up to and including last quarter;
  • proof of declaration of site and Checkin@work;
  • if you employ a foreign employee or appeal to a self-employed foreign national, the inspection service has the right to request any other document (e.g. work permit and/or occupation permit, Limosa declaration with L1 document, ...);
  • ….


The social inspector can also directly ask questions or request information from your employees who carry out their work on a construction site:

  • on his (her) status as an employee (salaried employee, self-employed person, student, temporary agency worker, etc.);
  • on his (her) status as a socially insured person (unemployed, unfit for work, integration income, pension, etc.);
  • on his (her) wage and working hours;

And can request certain documents to be submitted immediately:

  • employment contract with work schedule and derogation documents (part-time employees);
  • verification cards (unemployed employees);
  • permission for part-time resumption of work (incapacitated employees);
  • ….


In our LegalSmart webshop, you will find several of these standard documents. Legal all-in customers can contact their Legal Officer to obtain certain standard documents.
