Net zero push Costain aims to become a net zero business by 2035 with a focus on biodiversity and responsible procurement, signaling ongoing demand for sustainable infrastructure solutions and green project consulting across energy, water, transportation, and defence sectors.

Strategic expansion Recent investments in expanding facilities and increasing capacity, including a new pumping station project and European footprint growth, create opportunities for long-term EPC and digital-infrastructure services in regional water and utilities markets.

Talent pipeline Record apprenticeships and a growing workforce indicate strong demand for project delivery talent and knowledge transfer services, suggesting opportunities to offer training, digital upskilling, and workforce planning solutions to support major UK infrastructure programs.

Stable growth Revenue growth in H1 2026 and a continued high-tability operating margin point to a healthy financial position, enabling Costain to pursue larger, multi-year frameworks and strategic partnerships with utilities, highways, and defence stakeholders.

Key partnerships Ongoing MSP engagement with United Utilities and recognition for Civils Project of the Year highlight a track record in collaborative delivery and reuse of assets, presenting upsell potential for digital optimization, asset integrity, and sustainability-focused retrofit programs.
