Safe, reliable power is the foundation of every successful business, building, or infrastructure project. At Robert King Civils, we know just how much is riding on the performance of your HV (High Voltage) and LV (Low Voltage) cabling. That’s why organisations across the UK trust us to deliver robust, future-proof electrical installations that meet today’s demanding standards. Whether it’s a new commercial development, a complex renewables site, or critical upgrades in an industrial plant, every cable we install carries your reputation as well as ours.
With an eye for detail and a team of trained, accredited professionals, Robert King Civils brings together the knowledge, experience, and resources required for precision electrical work. Our services take you from project inception through to commissioning, certification, and handover.
All our work is performed fully in line with BS7671 IET Wiring Regulations and the latest NICEIC/NAPIT standards. We guide you through every step, supporting you with clear communication and practical advice from site survey right through to as-built documentation.
Here’s what sets us apart:
No two installations are ever the same, but our approach remains consistent: rigorous planning, clear compliance, and unwavering attention to quality. We cater to commercial, industrial, and specialist environments, including renewables, rail, healthcare, and defence.
Our full-service package includes:
Here’s a snapshot of what we deliver at every project stage:
Our HV / LV cabling process is structured to deliver quality and compliance at every stage. We begin with a thorough survey, including a site visit, CAD drawings, and hazard review. The design phase follows, where we determine cable type and sizing, prepare load schedules, and plan optimal cable routes. During installation, our team handles trenching, duct laying, and containment installation with precision. Termination and testing involve expert switchgear connections, VLF/IR testing, and jointing to ensure system integrity. Finally, we provide full certification, including NICEIC reports, grid compliance documentation, and comprehensive as-built records.
Robert King Civils installs and maintains a broad spectrum of electrical cabling across multiple voltages.
The information below summarises typical uses for each:
We install a full range of cable types to suit every project requirement. Low Voltage (LV) cables, operating between 230V and 400V AC, are typically used for lighting, power circuits, and retail units. Medium Voltage (MV) cables, ranging from 1kV to 33kV, are ideal for distribution boards and substations. For large-scale infrastructure, High Voltage (HV) cables—rated at 33kV and above—are deployed for grid feeders, wind and solar farms, and battery energy storage systems (BESS).
The physical route and security of your cabling matter just as much as the cable itself. We analyse your environment to recommend the best installation option, whether indoors or out, including:
With a full civils team in-house, our capability stretches from initial excavation and ducting right through to final reinstatement and surfacing.
Installation alone is never enough. Every project includes a suite of quality assurance and regulatory checks:
We’re used to coordinating with DNOs, main contractors, consultants, and utility stakeholders, smoothing the path from specification through to live grid connection.
Our versatility comes from working across a range of sectors, each with its own unique technical standards and commercial pressures.
Each environment is fully risk-assessed, designed to current regulations, and backed up by a tested process honed over years of delivery.
Choosing the right cabling contractor can make a huge difference to your project’s performance, reliability, and delivery timescale. Clients stick with Robert King Civils because we bring:
We understand each site presents unique challenges. That’s why we offer flexible installation windows, provide experienced supervisors on site, and co-ordinate with all parties — from DNO to architect — so you can stay focused on your wider project objectives.
