‘Weak’ Short-Term Confidence Drives New Tender Inflation Forecast

Why It Matters

Higher tender‑price inflation signals tighter cost pressures for builders, potentially slowing project starts and affecting profitability across the construction sector. The divergence from BCIS forecasts underscores uncertainty that investors and policymakers must monitor.

Key Takeaways

• Stace forecasts 3.5% tender price inflation in 2026.
• BCIS predicts lower inflation, 3.2% for 2026.
• Geopolitical tensions and energy costs pressure contractor margins.
• Residential builds face affordability and financing headwinds.
• London Grade A office space remains scarce, driving refurbishments.

Pulse Analysis

The construction industry is navigating a paradox of weak short‑term confidence and solid long‑term demand, a dynamic captured in Stace’s latest tender‑price inflation outlook. By projecting 3.5% inflation for 2026—higher than the Building Cost Information Service’s 3.2% estimate—Stace highlights the growing influence of geopolitical risk, especially the Middle‑East conflict, on energy markets and supply chains. These external pressures translate into higher input costs, prompting contractors to adopt more defensive pricing strategies while still scrambling to secure work amid uncertain market conditions.

For contractors, the forecast translates into tighter profit margins and a heightened need for operational efficiency. The report stresses that without sustained investment in skills development, productivity enhancements, and a robust project pipeline, the sector may struggle to meet the looming demand for housing and infrastructure. Supply‑chain disruptions and defensive supplier postures further erode margins, forcing firms to prioritize lower‑risk projects and defer higher‑risk ventures. This environment also amplifies the importance of strategic procurement and risk‑sharing arrangements to mitigate cost volatility.

The broader market implications are mixed. Residential construction remains under pressure from affordability constraints, weak buyer confidence, and elevated financing costs, potentially dampening new starts. Conversely, the prime London office market shows resilience, driven by a shortage of Grade A space that fuels refurbishment and Category B fit‑out activity. Policymakers and investors should watch these divergent trends, as sustained infrastructure investment could offset residential softness, while ongoing geopolitical tensions may continue to feed imported inflation, shaping the construction sector’s trajectory through the late 2020s.
