How Wage Growth Is Driving Construction Cost Inflation

Key Takeaways

• Labour costs rose 6.4% in 2025, outpacing materials.
• Skilled worker shortage of 244,000 since 2019 fuels wage pressure.
• Materials index up 2.6% in 2025, down from 25% 2022.
• Turner & Townsend forecasts 3.5% real‑estate TPI for 2026.
• Contractors favor simpler projects to safeguard margins.

Pulse Analysis

The construction sector’s cost dynamics have shifted from material‑driven spikes to a labour‑centric inflationary trend. Wage growth, now exceeding 6% annually, reflects both the National Living Wage increase and a deepening skills gap as more than two hundred thousand workers have left the industry since 2019. This shortage forces firms to compete for a shrinking talent pool, inflating salaries and pushing labour’s contribution to total project costs toward 40% when management and professional fees are accounted for. The result is a tighter cost structure that outpaces the modest 2.6% rise in material prices.

Contractors are responding by tightening risk management and revisiting contract models. Traditional fixed‑price contracts expose firms to margin compression when labour costs surge unexpectedly. Alternatives such as target‑cost agreements with incentive clauses allow risk sharing and encourage cost‑saving innovations. Sensitivity analyses across wage‑inflation scenarios are becoming standard practice, enabling firms to forecast cash‑flow impacts and adjust bid strategies accordingly. This risk‑averse posture also explains the industry’s tilt toward less complex, lower‑margin projects that are easier to price and deliver under volatile cost conditions.

Looking ahead, the interplay of modest material price stabilization and persistent wage pressure suggests that tender‑price inflation will continue to climb, with Turner & Townsend projecting TPI of 3.5% for real‑estate and 5.0% for infrastructure in 2026. Stakeholders—government, training bodies, and developers—must accelerate skills development pipelines to alleviate the labour crunch. In the meantime, firms that embed early cost planning, dynamic risk allocation, and robust supply‑chain resilience will be best positioned to protect margins and capture growth as construction activity rebounds.
