Addresses of construction firms and trades businesses in Switzerland

Building contractors, electrical, plumbing and heating installers, carpenters, roofers, painters and plasterers: for building material suppliers, manufacturers and software vendors who want to reach the businesses of one trade in a region by phone or post.

Our Swiss database holds 1,005,992 records (as of 4 November 2026): the entities in the commercial register and places from Overture Maps without a match. They are not yet assigned to industries; the quotation states the size available for this industry, the reference date and the delivery date.

Export of the whole industry: CHF 439 (final price). Selections by canton, municipality, language region or your own filters are quoted on request.

Official statistics: 50,651 businesses in Switzerland according to FSO, STATENT, table px-x-0602010000_106 (reference year 2024, table updated 20 August 2026). Divisions 41 construction of buildings (9,483), 42 civil engineering (923) and 43 specialised construction activities (40,245) combined. This is the size of the market, not the size of our database.

Preparing a regional list for suppliers

First define the trade and the delivery area, for example installation firms in the cantons of Aargau and Solothurn. Making the website a required field helps when you then check what each business offers.

The industry figure covers various construction and finishing businesses. It is neither a count of a single trade nor proof of an installation licence or association membership.

Price for the whole industry: CHF 439. A selection by region, sub-industry or required fields is quoted individually; the price for the whole industry is not a price promise for the filtered selection.

What Construction and finishing trades covers

Official statistics have no category called “skilled trades”. They classify businesses by activity: construction is section F of NOGA 2008, with the divisions construction of buildings, civil engineering and specialised construction. The Swiss types (six digits) are finer than in the EU, for example separating plumbing, plumbing with sheet metal work, and plumbing with heating.

The largest types according to the FSO (STATENT 2024): electrical installation (4,940 businesses), general building construction (3,122), maintenance and repair of buildings (3,117) and plumbing and heating installation (2,931). Joinery for interiors belongs to wood processing in NOGA (16.23) and thus to manufacturing; garages are under motor trade and garages.

Licences and registers: no trade directory

Switzerland has no general register of craftspeople. Federal law does require a licence for certain trades.

Installation licence for electrical work
Anyone who installs, modifies or repairs electrical installations needs an installation licence from the Federal Inspectorate for Heavy Current Installations ESTI (Art. 6 NIV). It requires a qualified person, for example with a master’s examination (Art. 7 and 8 NIV). Whether a business holds the licence must be checked with ESTI case by case; the export does not contain it.
Commercial register
A construction AG or GmbH is in the commercial register. A master painter running a sole proprietorship only has to register once turnover reaches CHF 100,000 a year (Art. 931 CO). For small businesses, address and phone are therefore often only public via their own website or directories.
Building permit notices
Building applications in Switzerland are put on public display and published in cantonal or municipal official gazettes. They show the client and the project, but not which firms carry out the work; they do not replace a company list.

Not in the export

  • ESTI installation licence or other licences
  • master’s titles and names of managers
  • association or collective agreement membership
  • number of employees and turnover
  • mobile numbers of individual fitters

These 16 columns are planned.

Trade and service area: two pitfalls when selecting

In statistics, each business has exactly one main activity. A plumbing and heating installer who also mounts solar systems is under 43.22.03, not additionally under electrical installation. Filtering by trade gives you the businesses with that focus, not everyone who offers the service.

The region follows the business address. A roofer from the canton of Schwyz often works in the canton of Zurich as well. For field sales territories along cantonal borders, include the neighbouring cantons in your request.

Many construction workers and fitters use mobile numbers. Mobile numbers are often not listed in the telephone directory and are then treated like numbers with an asterisk for sales calls (Art. 3 para. 1 let. u UWG).

Example request

We sell heat pumps through specialist trade and are looking for businesses focused on plumbing and heating (43.22.03) or HVAC (43.22.04) in the cantons of Bern and Fribourg that list a phone number. How many records is that, and what is the reference date?

Questions

Construction and finishing trades: frequently asked questions

Selection by NOGA type (for example 43.21 or 43.91.02) and canton or municipality is planned once the records carry a NOGA code; until then we check the definition in the quotation. It covers businesses with that main activity; where the assignment is missing or unclear, we say so before the quotation.

No. Switzerland has no general registration duty for trades businesses. Certain activities require licences, such as the ESTI installation licence for electrical installations (Art. 6 NIV).

Yes, if the number is listed in the telephone directory without the asterisk marking and you call from a displayed, listed number (Art. 3 para. 1 let. u and v UWG). Unlisted numbers are treated like numbers with an asterisk. Details: B2B marketing in Switzerland. The phone numbers in the export are not checked against the asterisk marking and are not intended for sales calls.
