The Polish construction industry - 2024 analysis

Section F at a glance

Construction (PKD section F) covers three large divisions:

• 41 - construction of buildings (residential and non-residential),
• 42 - civil engineering (roads, bridges, utility networks),
• 43 - specialised construction activities (installations, finishing, site preparation).

By number of registered entities, section F is consistently one of the largest in the Polish economy; by concentration - one of the most fragmented.

Industry cycle: scale year over year

Construction is strongly cyclical - growth correlates with public investment, mortgage availability, and EU programmes. Sector activity has grown over recent years, but unevenly.

Data: Aggregate of KRS filings and GUS data for section F, as of 2026-05-01.

Largest contractors

The revenue leaders are nationwide general contractors - infrastructure, energy, and rail. In the Mazowieckie voivodeship, where most large operators are registered:

Civil engineering (PKD 42)

Division 42 is dominated by companies working on roads, bridges, networks, and engineering structures. The segment is highly dependent on the CPK, KPO, and municipal investment pipelines:

Size distribution in the capital

To see where the "typical" contractor sits, look at the revenue distribution across all Warsaw-registered companies - the leaderboard above pulls firmly above the median:

Most profitable

Net margin in construction is traditionally lower than in IT or pharma, but varies sharply by sub-sector and customer type. Sorting by net profit highlights operators that managed to close the year well:

What this means for the market

“Construction rankings in Poland shift faster than in most industries - one large contract can lift a company several positions, the absence of one can drop it the same. To gauge the sector, watch the median and lower quartiles, not just the visible leaders.”

• The sector is fragmented - the top 10 share of total section-F revenue is a minority.
• Cyclicality demands a 3-year window for any judgement. A single year can be exceptionally strong or weak depending on the public-investment phase.
• The median sits noticeably below the average because of the large micro-enterprise tail - that's normal for construction and shouldn't be read as weakness.
