Insights on this address

Address of a group of related companies

50 companies are registered here now. 35 of the 50 companies are tied to one another, most likely as one group or family of companies. They are tied as follows: 30 in the ENGIE group, 9 named Engie, 7 named Wind4Flanders, 3 named Electrabel and 10 with a shared director. The building has about 43,900 m² of floor space, about 877 m² per company.

  • This address has more companies than 99.9% of Belgian addresses, which have at most 35.
  • 42 have their registered office here, 8 only an establishment or branch.
  • 10 of the 50 companies share a current director with another company here. The largest group has 10.
  • Half of the current companies have been registered here for less than 12 years.
  • 1 company is dissolved or no longer in the register.

Recommendations

  1. Open the network from this address to see which directors connect the companies.
  2. Assess a company at this address together with its group. Its dossier shows the structure and related companies.
Method and limits of this check

A shared address is not suspicious in itself. Office buildings, accountants and business centres host many companies. The verdict is about the kind of address, not about any individual company.

The comparison rests on all 1,408,687 active Belgian addresses. Half of them have one company, 95% at most five, 99% at most ten and 99.9% at most 35.

The list of an address holds the companies in the KBO register and those that left it since April 2026. A company that stopped before then is not in it. So the bankruptcies at this address are shown as counts. The comparison with Belgium runs over the postcode, for the same founding years and after the same number of years. It comes from the survival tables, which start from the founding deeds in the Belgian Official Gazette and count the companies that stopped too.

A shared director holds a current board mandate at two companies at this address. Statutory auditors and liquidators do not count.

Floor area and storeys are not measured anywhere. So the building shows them as estimates, next to the measured footprint. No register of building use (office, housing) is available.
