What we do

We operate across both regulated and non-regulated markets, providing clients and their customers with safe, reliable, and timely deliveries that align with their future demand. Underpinning our operations is a mature, digitally enabled Group Services platform that drives performance, efficiency, and resilience across all business units.

Strategic operational capability OCU’s capabilities span the full end‑to‑end lifecycle, from design through to build, commissioning, and maintenance. These include delivery across regulated power, water, digital infrastructure, and energy transition markets. Our extensive service offering is realised through three dedicated business units, supported by integrated design and delivery expertise. This structure enables us to respond rapidly to market needs while driving consistent quality and innovation across all programs. Our business units are OCU Energy, detailed on page 39, OCU Utilities, detailed on page 35, and RJ McLeod, detailed on page 43. Our activities support national programs in BESS, wind farms, pre‑enablement for synchronous condensers, regulated power upgrades, clean water delivery, digital fibre maintenance, renewable energy integration and more, as detailed in the Market opportunity and Case studies (pages 10 to 24). We deliver critical work for our clients throughout the UK, and our model will also support our international growth.

Operational governance Our leadership team, headed by the CEO and supported by the Group Board, ensures strategic alignment across all functions. Group Services, covering finance, commercial, technology, HR, SHEQ, legal, procurement, PMO, sustainability and more, has reached a new level of maturity this year, as detailed in the Operational highlights (page 2). This maturity enables consistent scalability, ensuring that our regional operations remain agile and responsive. With over 5,000 team members working across 41 key sites, OCU is structured to support nationwide delivery with local responsiveness. Co-location strategies, 24/7 operational hubs, and digital tools (see How we do it, pages 6 to 8) ensure streamlined execution across all service areas.

Confidence for the future Our proven capability in delivering complex infrastructure frameworks, programs, and projects is reinforced by a strong organic growth and strategic acquisition program, the deployment of modern operational processes, and continuous investment in training and innovation. Our commitment to sustainability, culture, and safety – outlined in Our culture and values (page 5) – provides a stable platform for long-term success. Whether delivering renewable energy programs, regulated water projects, digital infrastructure, or power frameworks, OCU Group’s integrated structure and broad capabilities make it a trusted partner in shaping the UK’s future infrastructure. Our international journey began in July 2025 with the addition of All Energy Contracting (AEC), which extended our footprint across Australia and New Zealand, reinforcing our commitment to accelerating change and shaping futures.
