Licences and permits

What official permissions, licences or consents are required by a building or engineering contractor before it can start work?

Belgium

Belgium

Construction works require a planning permit, which integrates the formerly separate building permit, environmental permit and socio-economic permit as of 1 January 2018. A planning permit is required for:

  • all types of construction works and also for some modifications to the designated use of buildings. The commencement of building works without such a permit is subject to criminal sanctions in each region;
  • certain types of installations with a ‘significant environmental effect’;
  • some commercial developments (mostly retail businesses), for example, for developments with a gross surface of more than 400 m².

The legislation governing the planning permit might contravene European law, and particularly the EU Directive 2006/123/EC (the Services Directive), to the extent that it gives the awarding administration the power to withhold a permission for the aforementioned commercial developments, unless the conditions of necessity, non-discrimination and proportionality have been met) (ECJ 30 January 2018, nrs. C-360/15 en C-31/16).

Professional requirements

Until recently, all builders working in Belgium had to comply with a number of professional requirements, mainly certifying professional competence. This requirement has been lifted for builders working in Flanders, but still apply for both Brussels and Wallonia.

Non-compliance can lead to the nullification of the building contract, so these requirements are of the utmost importance in practice.

For some construction projects, the employer must register the builders present on-site on a daily basis to Social Security, via the online registration process “Checkinatwork”.

When engaging foreign builders on a Belgian project, there is moreover the general obligation to file a preliminary LIMOSA-declaration to Social Security. This general obligation also applies when engaging foreign builders on a self-employed basis, as the construction sector was identified as an “at-risk sector” to which these declarations continue to apply.

Further, the employer has the obligation to verify that all foreign builders are in possession of a valid residence / work permit for Belgium during the entire duration of their assignment in Belgium.
