High voltage systems (typically defined as 1kV and above in the UK, ranging up to 132kV or higher) are the backbone of large-scale power distribution. These systems deliver the substantial power required for heavy machinery, manufacturing facilities, large retail complexes, office blocks, data centres, and infrastructure sites. Services are designed to ensure safe, reliable, efficient, and legally compliant operation throughout the system’s lifecycle.

‍

For Industrial Clients

Industrial sites often have high power demands, continuous operation needs, and complex equipment requirements. Services include:

• System Design & Installation
  • Custom design of high-voltage networks, switchrooms, substations, and distribution systems aligned with production needs and site layout.
  • Installation of transformers, switchgear, circuit breakers, protection relays, cabling systems, and metering equipment.
  • Integration with on-site generation systems such as backup generators, solar farms, or combined heat and power (CHP) units.
• Testing & Commissioning
  • Pre-commissioning checks, insulation resistance testing, protection system testing, and fault level analysis to verify performance and safety before use.
  • Thermal imaging surveys to detect overloaded circuits or faulty components.
• Maintenance & Servicing
  • Planned preventative maintenance programmes to reduce unplanned downtime, including cleaning, lubrication, calibration, and replacement of worn parts.
  • Emergency breakdown response and fault diagnosis to restore power quickly and minimise production losses.
• Upgrades & Modifications
  • Capacity increases to support new machinery or expanded operations.
  • Retrofits to improve energy efficiency, replace obsolete equipment, or integrate new technologies.
• Safety Services
  • Isolation and earthing services to enable safe working conditions for maintenance teams.
  • Risk assessments, hazard identification, and implementation of safety protocols.

For Commercial Businesses

Commercial premises require reliable power for operations, lighting, HVAC systems, IT infrastructure, and tenant facilities. Services include:

• Design & Installation
  • Design of high-voltage intake systems, substations, and distribution networks suitable for large buildings, retail parks, business parks, and public facilities.
  • Connection works to the national grid, including application management and coordination with distribution network operators (DNOs).
• Compliance & Certification
  • Preparation of all required documentation, test certificates, and compliance reports to meet regulatory standards and insurance requirements.
  • Periodic inspections to ensure systems remain safe and compliant over time.
• Energy Optimisation
  • Power quality analysis to identify issues such as voltage fluctuations, harmonics, or power factor problems that increase costs or damage equipment.
  • Installation of power correction systems to reduce energy bills and improve system efficiency.
• Maintenance & Emergency Support
  • Scheduled servicing to ensure systems operate reliably during business hours.
  • Emergency support to resolve faults quickly and minimise disruption to business activities or tenant services.
• Asset Management
  • Audits and reports on the condition and lifespan of equipment, helping businesses plan replacements and manage long-term costs.

Compliance & Standards

In the UK, all high-voltage work must adhere to strict regulations and standards, including:

• Electricity at Work Regulations 1989: Legal requirements for safe design, construction, maintenance, and use of electrical systems.
• BS EN Standards: Technical standards covering design, installation, testing, and maintenance of high-voltage equipment and networks.
• GS 6: Guidance note from the Health and Safety Executive (HSE) specifically addressing safety in high-voltage systems.
• Distribution Network Operator (DNO) Requirements: Standards set by local power distribution companies for connections to the national grid.

All work should be carried out by fully qualified, certified, and experienced engineers, often holding relevant industry accreditations.
