Statistics Norway’s residential construction cost index was 159.8 in August 2026, with 2015 set to 100. The index, updated on 14 September, fell 0.5% from July but was 3.8% higher than a year earlier.
The same table shows labour costs down 1.5% month on month and up 4.3% year on year. The materials index for residential construction rose 0.1% monthly and 2.4% annually. SSB says the index excludes changes in productivity and profit margins and is mainly used for escalation clauses in construction contracts.

Source and methodology
Haber Paper source-linked editorial data compilation; underlying sources retain their separate reuse terms.
Statistics Norway’s residential-building input cost index uses 2015=100. Changes compare August 2026 with July 2026 and August 2025; the series is not seasonally adjusted and does not measure sale prices, productivity or profit margins.
INSEE data for 2022 put the share of the region’s most polluting car classes at 29.8%, rising to 48.7% among car-owning households with the lowest incomes.
INE reported that the index fell 1.8% from the preceding quarter in the fourth quarter of 2026. The balance of firms expecting favorable conditions narrowed to 5.7 points.
