General contractors, electricians, plumbers and heating installers, roofers, painters and tilers: for building materials merchants, manufacturers and software vendors who want to reach the firms of one trade in a province by post or plan a sales territory.
Our Belgian database holds 779,149 records (as of 5 November 2026); they are not yet assigned to industries. The quote states the size available for this industry.
Export of the whole industry: €469 (excluding VAT). Selections by province, municipality or your own filters are quoted on request.
Official statistics: 139,472 businesses in Belgium according to Eurostat, Structural Business Statistics (sbs_ovw_act), number of enterprises (reference year 2024, Eurostat update of 30 September 2026, retrieved on 4 November 2026). Section F construction: divisions 41 construction of buildings, 42 civil engineering and 43 specialised construction activities (installation and finishing). This is the size of the market, not the size of our database.
First define the trade and the delivery area, for example heating installers in one province. With the website as a required field you can check each firm’s services afterwards.
The industry figure covers different construction and finishing businesses. It is neither a count of a single trade nor proof of a contractor approval.
Price of the whole industry: €469. A selection by province, sub-industry or required fields is quoted individually; the whole-industry price is not a price promise for the filtered selection.

Official statistics have no category called “trades”. They classify businesses by main activity: construction is section F of NACE-BEL 2008, with divisions 41 construction of buildings, 42 civil engineering and 43 specialised construction activities. All installers and finishing trades fall under it.
A garage or a hairdresser is not a construction firm, even if a craftsman works there. This industry covers construction and installation; the motor trade is under Motor trade and garages, engineering consultancies and architects under Architects and engineering firms.
| NACE-BEL 2008 | Official title | Note |
|---|---|---|
| 41 | Construction of buildings | residential and non-residential buildings (41.2) and property developers (41.1) |
| 42 | Civil engineering | roads and railways, utility networks, sewers and water projects |
| 43.21 | Electrical installation | electricians and solar panel installers |
| 43.22 | Plumbing, heat and air-conditioning installation | plumbers, heating and ventilation installers, heat pumps |
| 43.3 | Building completion and finishing | plastering, joinery, floor and wall covering, painting |
| 43.91 | Roofing activities | roofers; part of group 43.9 other specialised construction activities |
Construction firms are in the Crossroads Bank for Enterprises and some hold an approval for public contracts. None of these registers is an address book of tradespeople.
These 14 columns are included.
In the statistics a business has exactly one main activity. An installer who refurbishes bathrooms and also fits solar panels appears under 43.22, not additionally under 43.21. Filtering by NACE code gives you the firms with that focus, not all firms that offer the service.
The province follows the address in the source. A roofer based in Halle or Vilvoorde often works in Brussels but counts towards Flemish Brabant. If you plan a sales territory around Brussels or along the language border, include the neighbouring municipalities.
Calling contractors without prior consent is allowed, but you must first check the numbers against the “Bel-Me-Niet-Meer” (Do Not Call Me) list; this also applies to businesses. For email without consent, only impersonal addresses of legal entities qualify, with an offer intended for legal entities.
We sell heat pumps through specialist trade and are looking for installers with main activity 43.22 in Limburg and the province of Antwerp that have a website, for a letter inviting them to a training session. Property developers and pure design offices can be left out. How many records is that and how current are the data?

Questions
Yes, on request. We build the selection from the category and the name in the source (for example electrician or plumber) and the province or municipality. Our records do not yet carry a NACE-BEL code; before quoting we tell you how many records this finds and how reliable the selection is.
Yes, telephone prospecting without consent is allowed in Belgium, provided you check the numbers against the “Bel-Me-Niet-Meer” (Do Not Call Me) list beforehand and stop calling anyone who objects. Automated calls, text messages and fax do require consent. More in the guide telemarketing to businesses.
Yes, the database covers the whole of Belgium. You choose the provinces or the Brussels-Capital Region; the quote states the number per selected region.
