Highways spends £50m buying Thames Crossing houses

National Highways has spent more than £50m acquiring properties related to the £10.6bn Lower Thames Crossing, purchasing 71 properties (including 51 within the route for £37.6m and 20 outside order limits for £12.8m) and receiving about £5.1m in rental income since 2018. The 14-mile crossing, approved in March 2025 and due to open in the early 2030s, has reduced affected properties by almost 70% via voluntary agreements but still faces community opposition and the prospect of compulsory purchases for remaining assets. For investors, the update highlights early project-related capital deployment and potential contingent liabilities tied to land acquisition and planning risk rather than any immediate market or corporate-earnings impact.

Analysis

Market structure: The LTC is a ~£10.6bn, multi-year demand pulse for civil contractors, materials and logistics; main winners are large diversified contractors (scale to win ~£100m+ packages), aggregates/cement producers and regional logistics property owners near new junctions. Losers are small regional housebuilders and existing local landlords whose assets sit in demolition/compulsory purchase corridors — expect localized residential price compression of 5–15% peak-to-trough within 5km of the route during construction (next 1–5 years).

Risk assessment: Key tail risks are legal/political reversal or multi-year procurement delays (HS2-style) that could push awards >24 months and cause margin compression; cost-overrun inflation risk (if construction inflation >5% YoY) would hit contractor equities and increase government bond supply. Immediate (days) market moves minimal; watch procurement notices in 3–9 months and first main-works awards in 6–18 months; long-term (3–10 years) network effects likely uplift logistics rents by 5–12% around new junctions.

Trade implications: Favor concentration in large-cap contractors and materials (ability to absorb mobilisation) and logistics REITs that capture improved connectivity; avoid or hedge small/mid-cap UK housebuilders with heavy SE/Essex/Kent exposure. Use relative-value and event-driven sizing around procurement milestones: expect meaningful re-rating on contract awards and CPI-driven pass-through for materials firms within 6–18 months.

Contrarian angles: Consensus overweights pure contractors; under-appreciated are recurring rental cashflows National Highways is already generating (~£5.1m since 2018) signalling an operational landlord role — opportunity for specialist residential management services and local buy-outs after construction. Also, historical parallels (HS2) show politically exposed projects trade with long volatility: nimble options and event-driven pair trades will outperform buy-and-hold exposure.

Key Decisions for Investors

• Establish a 2–3% portfolio long position split between Balfour Beatty (BBY.L) and Costain (COST.L) — 1–1.5% each — enter within 0–3 months, add up to another 1% on confirmed main-works contract award (trigger window 6–18 months); target 12–24 month horizon, take profits at +15–25%, stop-loss at -12%.
• Buy a 2% long in materials leader CRH (CRH.L) to capture sustained aggregate/cement demand; hold 12–36 months and scale up by +1% if UK building-materials CPI rises >3% YoY or if CRH announces LTC-specific supply contracts; target +15% return, stop-loss -10%.
• Implement a 1.5% pair trade: short Persimmon (PSN.L) 1.5% vs long SEGRO (SGRO.L) 1.5% to express underperformance of local residential vs logistics real estate over 6–24 months; cover short if Persimmon raises reservations or regional volumes recover by >10% vs prior quarter.
• Use options for event risk: buy a 12-month call spread on BBY.L (long ATM, short +20% strike) sized to 0.5–1% portfolio risk to play contract awards, and buy 6–12 month puts 15% OTM on a small regional housebuilder (e.g., BDEV.L or PSN.L) sized 0.5% to protect against local housing downside if compulsory purchase notices rise.
