We work in a wide range of sectors from power and energy transition, through to the water and digital infrastructure industries.
OCU Group is at the forefront of ensuring the critical services that we all rely on are ready for the UK’s renewable energy powered future. Our commitment is to innovate and deliver sustainability, while designing, building and maintaining these vital services for our clients’ customers.
Energy Transition
As the UK intensifies its efforts towards achieving net zero by 2050, the demand for electricity is surging, accelerated by the rise of electric vehicles, increased electrification in various markets, and the development of new housing to accommodate a growing population. More families and businesses are connected to the grid than ever before, highlighting an essential shift in energy usage and needs.
OCU is at the forefront of this conversion, working closely with both regulated and non-regulated sectors. We collaborate with distribution and transmission network operators – the companies who own and operate the network of cables, transformers and towers that bring electricity from the national transmission network to businesses and homes – to enhance their power infrastructure, integrating more renewable energy sources and enhancing the flexibility of energy distribution.
These advancements are crucial in reducing the long-term costs of electricity in the UK and supporting the national goal of sustainability.
Our extensive team of specialists is dedicated to expanding grid connectivity and ensuring continuous, reliable service. We provide essential repair and maintenance services that not only keep the power flowing but also adapt to the evolving demands of a modernised energy system, securing a sustainable energy future for all.
Regulated Power
As the UK electricity system undergoes a generational upgrade to meet net zero and decarbonisation targets, the role of regulated power infrastructure is critical to meeting the goals. The accelerated growth of electric transport, heat networks and decentralised energy generation is increasing pressure on distribution and transmission networks, necessitating investment in capacity, resilience, and intelligent grid control.
OCU is helping its clients lead the way for this transformation, partnering with electricity Distribution Network Operators (DNOs) and Transmission Operators (TOs) to deliver safe, high-quality, and compliant infrastructure across the UK. Our work spans the RIIO-ED2 and RIIO-T2 regulatory periods. It includes design, build, commissioning and maintenance of substations, overhead lines, cabling and switching assets, ensuring the network can meet future load growth and integrate increasing volumes of renewable generation.
We are proud to support critical connections that power homes, public infrastructure, and business operations while also playing a vital role in ensuring the stability of the national grid. Our in-house engineering, delivery and operational teams bring deep regulatory knowledge and technical excellence, contributing to long-term grid performance and sustainability improvements. Through these efforts, OCU supports a smarter, stronger, more flexible energy system that is shaping reliable power for future generations.
Digital Infrastructure
In today’s interconnected world, high-speed internet access is not just a convenience; it’s a cornerstone of modern life, driving personal, social and economic progress. As the UK continues to evolve its digital landscape, connectivity shapes everything from daily communications to business operations, education and leisure.
OCU stands at the forefront of this digital transformation as a market leader in telecoms infrastructure. We are deeply involved in both urban and rural fibre rollouts, ensuring that communities across the UK, regardless of location, gain access to fast and reliable internet. Our comprehensive services include the installation, termination and testing of fibre optic cables, offering customised turnkey solutions to meet the diverse needs of our clients.
Our teams of highly skilled engineers not only deliver projects of any scale but also engage in the maintenance, renewal and upgrading of existing networks to enhance connectivity continually. In London, we are pushing the boundaries of technology with innovative cellular work, setting new standards for mobile communication in the capital. Through these efforts, OCU is not just keeping families and businesses connected; we are building the foundations for a future where digital accessibility is universal.
Water & Wastewater
Access to clean water and effective sanitation remains a global priority, underscored by UN initiatives to improve water quality, wastewater treatment, and safe reuse. This commitment also extends to minimising the impact on water-related ecosystems.
For over 20 years, OCU’s Water and Wastewater business has been at the forefront of developing efficient, effective and environmentally friendly water and wastewater networks, treatment facilities and ancillary equipment. We are renowned for delivering reliable solutions and providing emergency support, ensuring uninterrupted water services for our clients and their customers.
Our extensive portfolio encompasses projects and framework contracts for many of the UK’s leading water and wastewater companies, private developers, and tier one capital delivery organisations, demonstrating our continued commitment to maintaining and enhancing the UK’s water infrastructure.
