Cable Systems Consultancy
Need independent cable engineering expertise for complex power and energy projects?
Cable engineering consultancy services to support your project goals.
When cable systems need to perform reliably, getting the specification right is critical. As cable system consultants, we go beyond simply supplying products to provide end-to-end technical expertise to asset owners, DNOs and contractors.
Our experts make sure your cable systems are correctly specified, compatible, compliant and practical to install, with independent advice that can help identify potential issues before they become costly problems.
What does a cable systems consultancy do?
Our focus is on making sure the complete cable system – not just the individual cable – is correctly designed, specified and delivered.
We work with project teams from the earliest stages, helping to identify technical considerations and potential risks before they affect cost, programme or installation.
Our cable system consultants can support you with:
- Specification and design reviews
- Cable selection and technical assessment
- System and component compatibility
- Installation and buildability considerations
- Standards, compliance and DNO requirements
- Technical queries and project changes
- Existing cable system reviews
- Identifying and resolving potential installation issues
Our cable engineering consultancy services
Specification and engineering support
We consider more than electrical performance in cable system specification – taking into account environmental conditions, installation methods, operating requirements, applicable standards and project constraints.
System design and compatibility
By assessing compatibility across the entire cable system, our experts can reduce the risk of mismatched accessories, performance issues and installation problems, particularly on complex projects.
Buildability and installation efficiency
A system that works on paper still needs to work on site. We consider practical factors including cable routing, handling, access and installation methods, identifying potential challenges before installation begins.
Compliance and DNO approvals
Cable systems need to meet relevant technical standards, network requirements and approval processes. We have extensive experience supporting DNO approvals and wider compliance requirements.
What sectors do we work with?
Our cable systems consultancy supports projects across power infrastructure, energy generation and other applications where cable performance is critical.
We work across:
- Power distribution and DNO networks
- Power transmission infrastructure
- Battery Energy Storage Systems (BESS)
- Solar and wind energy projects
- Flexible generation
- Data centres and critical environments
- Green hydrogen developments
- Hydropower schemes
We’ve supported more than 100 projects across solar, BESS and other infrastructure schemes.
Every project brings its own technical requirements, standards, approval processes and installation challenges. Our role is to provide the specialist cable expertise needed to navigate those requirements and make informed decisions.
