Navigating the UK Construction Sector's Divergence: Where to Invest in a Contracting Market

The UK construction sector finds itself at a crossroads: contracting activity across key subsectors, rising input costs, and shifting sentiment. Yet, within this challenging landscape, opportunities for resilient growth are emerging. Investors must parse the nuances of subsector performance, cost dynamics, and emerging demand trends to identify pockets of strength.

The Divergence in Subsector Performance

The May 2025 UK Construction PMI data reveals stark contrasts. While residential construction—long the sector's backbone—posted a PMI of 45.1, its fifth consecutive month of contraction, commercial construction stabilized at 49.5, marking the slowest decline since January 2025. Meanwhile, civil engineering languished at 45.9, its weakest reading for the fifth straight month.

The residential sector's slump reflects affordability crises, high borrowing costs, and weak consumer confidence. Housebuilding activity has deteriorated further, with developers citing delayed client decisions and stagnant demand. However, this sector's trajectory may soon shift. Business confidence in residential workloads has surged to its highest level since December 2024, buoyed by expectations of infrastructure projects like Hinkley Point C and HS2, which could unlock housing demand tied to job creation.

Commercial and Civil Engineering: A Cautionary Tale

Commercial construction's modest stabilization at 49.5 masks lingering vulnerabilities. While the pace of contraction slowed, demand remains subdued, and firms are hesitant to commit to large projects. Civil engineering, meanwhile, faces persistent headwinds, including delayed public infrastructure projects and weak demand. Its PMI of 45.9 underscores the sector's struggle to recover.

Investors should approach commercial developers with caution. Overexposure to this subsector risks exposure to prolonged declines, as companies grapple with margin pressures and stagnant order books.

Input Costs: A Persistent Headwind, but Opportunities Lurk

Input cost inflation remains stubbornly high, though the rate of increase has slowed slightly. Timber, concrete, insulation, and aggregates saw the sharpest price rises, driven by global supply chain strains and potential U.S. tariffs. Conversely, fuel costs dropped, offering marginal relief.

Here lies an investment angle: firms with vertical integration or alternative material sourcing strategies could mitigate these cost pressures. For instance, companies leveraging recycled materials or modular construction techniques might outperform peers.

Order Books and Employment: A Fragile Foundation

New work declined at the slowest pace in four months, but employment dropped sharply—the fastest rate since August 2020. Subcontractor usage also fell to a five-year low, signaling cost-cutting measures. This underscores a sector in survival mode, with firms prioritizing cash flow over expansion.

Yet, the data hints at a potential turning point. Improved sales projections in commercial real estate and optimism around infrastructure spending suggest a cyclical rebound could materialize in late 2025 or 2026.

Investment Strategy: Tactical Tilts and Defensive Plays

1. Residential Focus: Target firms exposed to affordable housing initiatives, such as Barratt Developments (BDEV) or Taylor Wimpey (TW), which have emphasized lower-cost housing projects. These companies may benefit from government subsidies and urban regeneration programs.
2. Cost Mitigation Leaders: Invest in construction materials firms with supply chain resilience, such as CRH (CRH), which sources aggregates domestically, or Tarmac, part of Vinci SA (DGFP.PA), which has diversified into low-carbon materials.
3. Avoid Overexposure to Commercial Developers: Firms like Land Securities (LAND) or British Land (BLND) face prolonged declines unless commercial demand rebounds sharply—a riskier bet in the near term.

Final Considerations

The UK construction sector's recovery hinges on three variables: interest rate cuts, public infrastructure spending, and global supply chain normalization. While risks remain elevated, investors who tactically allocate to residential housing and cost-advantaged firms can position themselves to capitalize on an eventual rebound.

In summary, the UK construction sector is not a monolith. By focusing on subsectors with defensive demand drivers and companies adept at navigating cost inflation, investors can navigate the contraction—and even profit from it.
