How many construction companies are there in Poland?

The number

69,839 active registered construction and trades companies. That is the count in our Polish register snapshot as of August 2026, restricted to entities with an active status and a registered activity classification in this sector.

The figure counts registered legal entities. Counts that include sole traders operating under CEIDG run much higher, because a large share of Polish activity in every sector is carried out by one-person businesses that never appear in the company register.

Construction is the only large Polish sector where new registrations have risen in each of the last four years. That trend is the most useful thing on this page: a sector adding seven thousand surviving companies a year is a sector where nobody has an entrenched supplier.

Where they are

Mazowieckie holds 26.6% of the sector, against 33.3% of the register as a whole, so the concentration here is lower than the national pattern.

The largest cities

Silesia is under-represented by city name because it is polycentric. A campaign targeting the region by naming Katowice will miss most of it, and the voivodeship table above is the better filter.

Revenue bands

Filed revenue is available for 32,083 of the 69,839 companies, from the most recent financial year on file, mostly 2022 to 2024. Figures are in Polish zloty.

45.9% of the sector has a filed figure, so revenue is usable as a filter on about half of the market. The companies without one skew smaller and younger, so filtering on revenue quietly biases a list towards established firms.

Website presence

12,475 of 69,839, or 17.9%, have a website in our data. The sector average across the whole Polish register is 21.9 percent.

That matters because most prospecting stacks begin with a domain: find the company, find the site, guess the email pattern, verify it. Remove the site and the chain breaks at step one, so a domain-first workflow covers only the online slice of this sector and misses the rest.

New registrations

Companies registered in each year that are still active today.

The 2026 row covers January to August only. Because the population is restricted to companies that are still active, older cohorts are understated by the firms that have since closed.

What this means for targeting

Target by registration year, not by size. With 7,458 companies registered in 2025 alone still active, and 4,156 more in the first eight months of 2026, the newest cohort is large enough to be a campaign on its own. A construction firm in its first two years is buying insurance, equipment finance, accounting, site software and labour.

Revenue splits the market cleanly. 10,937 companies file under 100,000 zloty and are effectively one-person operations. The 3,631 in the 2m to 10m band and the 1,141 above it are the contractors with sites, crews and procurement.

Web presence at 17.9 percent is below the national average. Trades companies win work through developers, general contractors and referral, so a domain-first list misses most of the sector.

How the count was made

The snapshot is built from Polish register data, deduplicated on registration number and filtered to entities with an active status. Sector is derived from the registered activity classification and grouped into the categories used across this site, so a company with mixed activity is assigned to its primary classification.

Revenue is the most recent filed figure available per company rather than a common year, so the bands describe the register as filed rather than a single accounting period. Website presence means we hold a domain associated with the record, not that the site is live today.

Every figure on this page comes from one query against that snapshot.
