Flash checks construction 2025: avoid fines digitally
Flash inspections in the Belgian construction industry (summer 2025): how to avoid fines with digital solutions?
In summer 2025, the Belgian social inspectorate (SIOD/SIRS) will again organize unexpected flash checks in the construction, electrical engineering and metal sectors. These checks focus on labor compliance and the prevention of social fraud, such as undeclared work, illegal employment or erroneous Dimona declarations.
Are you an SME in construction, work with subcontractors or have mobile shifts on multiple sites? Then this is the time to put your records in order - and ideally digitize.
What does social inspection check during a flash check?
Documents you should be able to show immediately:
- Work regulations: with working hours, breaks, shifts and psychosocial attachments.
- Employment agreements: for full-time, part-time, temporary, student and foreign employees (LIMOSA).
- Dimona declaration: are all employees declared correctly and on time?
- CheckIn@Work registration: mandatory electronic attendance registration at large construction sites.
- Proof payment & pay slips: including meal allowances, mobility allowances and bonuses.
- Accident Insurance: active for all employees and subcontractors.
- Daily attendance or timekeeping: paper or digital.
What if you are not in order,
- Administrative or criminal fines up to tens of thousands of euros.
- Recovery of social security contributions in the event of irregularities.
- Temporary cessation of a yard or project.
- Reputation damage to clients or authorities.
For SMEs in construction and engineering, these risks are severe. Prevention pays off.
