Poland's construction output fell 9% in September, with building work down 19%

September by division

• Construction of buildings: −19.2% on the year.
• Specialised construction work: −6.1%.
• Civil engineering: −4.1%.
• Compared with August, total output rose 3.0%. After seasonal adjustment it was 7.2% lower than a year earlier.

For January–September, output was 4.7% below the same period of 2025. Companies told GUS the fall was linked to irregular settlements and a high base in September 2025.

In the GUS business survey, almost 32% of construction companies reported lower output than a year earlier.

What it means

Construction output measures the value of work done in a month, not the number of homes. Housing data point the other way: completions rose 3.1% and permits 12.3% in January–September (our report). A weak month for building work does not yet show a slowdown in new flats, but it is worth watching in the October data.
