Frequently asked questions
Which company in Architectural and engineering activities; technical testing and analysis in Walloon Brabant has the highest revenue?
Westinghouse Electric Belgium, with €77.1m of published revenue (financial year 2025).
Why are some companies missing?
Small companies (micro and abridged accounts) do not have to publish their revenue: only the 52 that publish it, out of 918 companies in the sector in the area, are ranked.
Why does this ranking differ from other lists?
It uses each company's annual accounts as filed with the National Bank, not consolidated group accounts. A holding, a subsidiary or a purchasing entity can therefore appear separately. Only companies whose latest accounts are less than 3 years old are ranked.
