Through our specialist subsidiary Navitas Engineering, we offer end-to-end electrical engineering consultancy across the full asset lifecycle; from feasibility and design through to testing, commissioning and in-service optimisation. This integrated approach ensures that power systems are not only technically robust, but also efficient, compliant and aligned to long-term operational needs. Navitas brings extensive experience in railway electrification and power distribution, supporting complex infrastructure programmes across the UK and internationally.
By combining Octavius’ proven delivery capability with Navitas’ specialist design and engineering expertise, we provide a seamless, collaborative solution that reduces risk, drives efficiency and enhances network resilience, keeping vital transport systems moving safely and reliably.
What we deliver
Power system design & analysis
Developing efficient, high-performing power systems starts with a deep understanding of both current operational demands and future network requirements. Our team provides detailed system modelling, analysis and design that ensures electrical infrastructure is robust, resilient and capable of supporting evolving usage patterns, including increased electrification and digital integration.
By applying advanced modelling techniques and engineering expertise, we help clients make informed decisions early in the project lifecycle, optimising system performance while controlling cost and complexity. This proactive approach reduces the need for rework and ensures infrastructure is right-sized and future-ready from the outset.
Our focus is always on delivering practical, buildable solutions that integrate seamlessly into live operational environments. The result is a power network that performs reliably under pressure, supports long-term asset strategies and enables confident investment in future upgrades.
Rail electrification engineering
Electrification is central to the decarbonisation of transport networks, but it requires careful planning, integration and delivery to minimise disruption and maximise value. We support clients across all aspects of rail electrification, from system design and specification through to engineering assurance and implementation support.
Working within complex rail environments, we provide expertise in areas such as traction power systems, earthing and bonding, and protection and control. This ensures systems are not only safe and compliant but also optimised for operational efficiency and long-term reliability.
By combining technical excellence with a collaborative delivery approach, we help accelerate electrification programmes by reducing risk, improving constructability and enabling the transition to cleaner, more sustainable rail infrastructure.
Substations & power supply infrastructure
Reliable power supply is critical to the safe and efficient operation of transport and infrastructure networks. We design and support the delivery of substations and associated power supply assets that provide secure, resilient energy distribution in even the most demanding environments.
Our approach considers the full asset lifecycle, from initial concept design through to integration, upgrade and renewal. This ensures that infrastructure not only meets current performance requirements but can be adapted cost-effectively as demand evolves.
By prioritising reliability, maintainability and safety, we help clients reduce downtime, enhance asset performance and ensure continuity of service - keeping critical infrastructure running smoothly for end users and operators alike.
Testing, commissioning & assurance
Ensuring that power systems perform as intended is essential to achieving safe, reliable and compliant operations. We provide comprehensive testing, commissioning and assurance services that validate system performance and confirm readiness for operation.
Our teams work closely with clients and stakeholders to identify risks early, resolve issues efficiently and ensure all systems meet required standards and specifications. This rigorous approach minimises delays at critical handover stages and builds confidence in system integrity.
Beyond commissioning, we support ongoing assurance and optimisation, helping clients maintain performance, manage risk and extend asset life. The result is infrastructure that delivers consistent, dependable outcomes throughout its operational lifecycle.
