Material impactConstruction materials remained the biggest contributor to the increase in building cost inflation during the period. The GSS said the fall in cement and steel prices made the biggest negative contribution to building cost inflation and helped to limit the overall increase in construction costs. Households can plan construction more confidently while keeping a close watch on building material prices,” the Government Statistician, Dr Alhassan Iddrisu, said. The latest PBCI figures showed that while construction costs continued to rise annually, the pace of growth had slowed considerably compared with 2025. Lower labour costs and declining prices for cement and steel helped to contain overall inflation, although higher plant costs and selected material prices remained areas of concern for construction businesses.
