The average prices of key construction components, including concrete and asphalt, doors, fuel and transport, rose in the second quarter of 2026, pointing to elevated building costs for developers and contractors.
The Kenya National Bureau of Statistics (KNBS) says growth in the Construction Input Price Index (CIPI) rose by 5.73 percent from 119.51 in the first quarter of 2026 to 126.36 in the second.
CIPI tracks changes in the cost of essential inputs like cement, steel, wages, transport and energy.
The jump is the highest since the last quarter of 2022, which posted a 7.10 percent growth.
“The increase was primarily driven by an increase in the indices of transport, fuel and construction materials,” KNBS said.
“Transport, fuel and lubricant indices recorded the largest increase of 21.47 per cent, largely due to a 31.16 per cent increase in the fuel and lubricants indices and a 12.34 percent rise in transport costs.”
Data from the Energy and Petroleum Regulatory Authority shows that in the quarter under review, the price of petrol rose to an average of Sh208.63 per litre from Sh179.69 in Q1.
Cement consumption rose by 6.83 percent in the quarter under review, suggesting that developers pushed ahead with projects in the pipeline as input prices rose.
“Notable price increases were observed for concrete and asphalt (7.25 percent), cement (6.99 percent), ballast/gravel and graded crushed stones (6.16 percent), electrical fittings (6.27 percent), paints (8.43 percent) and kerbs (5.89 percent),” KNBS said.
“The labour indices increased by 4.38 percent, reflecting higher wages across labour categories, particularly carpenters, painters, welders and mechanics (7.51 percent). The equipment index rose by 2.48 per cent, with increases recorded across all machinery categories.”
The building cost indices increased from 119.77 in the first quarter of 2026 to 126.06 in the second quarter, a 5.25 percent rise.
“The increase was driven by higher prices across major input categories, particularly transport and fuel, construction materials and labour,” KNBS said.
The value of building plans approved in Nairobi in the same period rose marginally by 1.98 percent to Sh52.01 billion from Sh51 billion.
