Construction Costs in Kenya: What's Driving Prices Up in 2026

If you've priced out a construction project recently and the numbers came back higher than you expected, you're not imagining it. Kenya's construction costs jumped sharply in the second quarter of 2026 — the steepest quarterly increase in nearly four years — driven by a combination of fuel prices, material costs, and rising labour wages. Here's what's actually behind the increase, and what it means if you're planning to build.

The Numbers: How Much Have Costs Actually Risen?

According to the Kenya National Bureau of Statistics (KNBS), the Construction Input Price Index (CIPI) — which tracks costs for cement, steel, wages, transport, and energy — rose by 5.73% in a single quarter, climbing from 119.51 in Q1 2026 to 126.36 in Q2 2026. This is the steepest quarterly jump since Q4 2022, when the index grew 7.10%.

The Building Cost Index specifically rose from 119.77 to 126.06 — a 5.25% increase — while the Civil Engineering Cost Index climbed from 123.13 to 130.18, reflecting similarly steep increases across infrastructure projects.

What's Actually Driving the Increase

Fuel and Transport: The Biggest Factor

The single largest contributor was fuel and transport costs, which rose a striking 21.47% in the quarter — driven by a 31.16% increase in fuel and lubricant costs and a 12.34% increase in transport costs specifically. Since nearly every building material — cement, steel, timber, roofing sheets, tiles, aggregates — has to be transported from manufacturing plants or quarries to the construction site, rising fuel costs ripple through almost every line item in a construction budget, not just the materials most directly associated with fuel.

Cement and Core Materials

Cement prices rose 6.99% in the quarter, with concrete and asphalt up 7.25%, ballast and graded crushed stone up 6.16%, and paints up 8.43%. Notably, cement consumption still rose 6.83% during the same period — suggesting many developers pushed ahead with projects already in the pipeline despite rising input prices, rather than pausing to wait for costs to stabilize.

Labour Costs

The labour index rose 4.38%, with wages for carpenters, painters, welders, and mechanics climbing a combined 7.51% — reflecting a tightening skilled labour market pushing up costs for the human capital side of construction, not just materials.

Steel: A Separate, Volatile Story

Steel reinforcement bar prices have shown particular volatility, having risen 5.2% year-on-year as of late 2025 — the highest single sub-index movement in that period — and remain sensitive to global commodity markets and exchange rate movements, given Kenya's construction sector combines domestic production with imported raw materials.

Current Construction Costs Per Square Metre (2026)

Based on current market data, construction costs vary considerably by building type and finish level:

• Bungalows: roughly KSh 48,000–65,000 per square metre
• Maisonettes: roughly KSh 60,000–85,000 per square metre
• Luxury builds: roughly KSh 85,000–120,000 per square metre
• Industrial warehouses/basic godowns: the lowest end of the range, roughly KSh 30,000–50,000 per square metre, given simpler structural systems and minimal internal finishes

These figures generally exclude land cost, professional fees, external works, and VAT on imported materials — a useful planning tool, but not a substitute for a detailed quotation from a quantity surveyor or contractor for your specific project.

Current Material Price Ranges

• Cement: roughly KSh 700–850 per 50kg bag, with the Nairobi market averaging around KSh 750
• Steel reinforcement: roughly KSh 95,000–120,000 per ton, with continued volatility expected
• Roofing materials: roughly KSh 600–1,200 per metre, depending on gauge and type

What This Means If You're Planning to Build

Budget with a larger contingency than usual. Given the pace and volatility of recent cost increases, industry professionals suggest that projects with high structural steel content in particular should carry an additional 3–5% contingency above the standard recommended buffer, given steel's outsized recent price movement.

Get current quotes, not historical estimates. Cost per square metre figures are a useful planning tool, but given how quickly conditions have shifted in 2026, relying on last year's pricing (or even last quarter's) can meaningfully understate your actual project cost.

Consider timing carefully. If your project has some flexibility, monitoring quarterly KNBS construction cost data can help identify whether costs are stabilizing or continuing to climb — though waiting indefinitely for lower prices carries its own risk if the underlying trend continues upward.

Factor this into build-to-rent planning. If you're evaluating a build-to-rent project, current elevated construction costs directly affect your total investment and expected returns — worth revisiting your numbers against current pricing rather than earlier estimates.

Is There Relief in Sight?

The broader picture is somewhat more nuanced than the sharp Q2 2026 jump suggests — year-on-year construction input price growth had actually been comparatively moderate through much of 2025, before the sharper fuel-driven increase in Q2 2026. Longer-term industry outlooks point to relatively stable cement and concrete demand, continued adoption of locally manufactured materials as a way to moderate costs, and ongoing sensitivity of imported materials to exchange rate movements — suggesting costs are likely to remain a moving target rather than settling into a clear, stable trend in the near term.

FAQs

1. Why did construction costs in Kenya rise so sharply in 2026? The main driver was a 21.47% increase in fuel and transport costs in Q2 2026, which pushed up the cost of nearly every building material since most have to be transported to site — combined with rising cement, steel, and labour costs.

2. How much does it cost to build a house in Kenya per square metre in 2026? It varies by building type and finish: roughly KSh 48,000–65,000/m² for bungalows, KSh 60,000–85,000/m² for maisonettes, and KSh 85,000–120,000/m² for luxury builds, excluding land, professional fees, and VAT on imported materials.

3. What's the current price of cement in Kenya? Cement generally costs roughly KSh 700–850 per 50kg bag as of 2026, with the Nairobi market averaging around KSh 750 per bag.

4. Should I build now or wait for construction costs to come down? This depends on your specific timeline and flexibility — costs have been volatile rather than steadily declining, so waiting indefinitely carries its own risk. Getting current, detailed quotes and building in a larger contingency is generally more practical than trying to precisely time the market.

5. Is steel or cement more volatile in price right now? Steel reinforcement has shown particular volatility, tied to global commodity markets and exchange rate sensitivity, while cement price movements have been somewhat more moderate, though still rising.

6. How much contingency should I budget for a construction project in the current environment? Beyond the standard recommended contingency (commonly around 10%), industry professionals suggest projects with significant structural steel content should budget an additional 3–5% given steel's recent price volatility.
