Specialists in High Voltage Electrical Services

FAQs

General

We provide high voltage (HV) and low voltage (LV) electrical services nationwide, including cable jointing, LV terminations, new installations, remedial works, COMAH-compliant substation inspections, fault finding, and planned maintenance.

We support sectors such as renewable energy (wind and solar), warehousing and logistics, commercial and industrial premises, corporate offices, and retail venues.

We work across Great Britain, delivering projects and maintenance programmes for single and multi-site clients.

Yes. We provide rapid fault diagnosis and emergency repairs for HV and LV systems to reduce downtime and keep your operations safe.

Services & Technical

We handle LV systems and a wide range of HV networks typically including 11kV, 33kV and above, depending on site requirements and network design.

Cable jointing is the precise joining or terminating of power cables to ensure electrical integrity, safety, and performance. High-quality jointing reduces failures, hot spots, and unplanned outages.

Absolutely. Our engineers perform LV terminations alongside HV installations and maintenance to provide a complete power solution from end to end.

We offer design, installation, testing, and commissioning. Where required, we collaborate with your consultants or grid stakeholders to deliver compliant designs optimised for safety, efficiency, and lifecycle cost.

Yes. We design, install and maintain renewable energy electrical infrastructure, including collector systems, HV cabling, terminations, switchgear, protection settings, and grid-ready commissioning.

Yes. We carry out substation inspections and help sites meet COMAH and associated safety obligations, including visual and thermal inspections, condition assessments, remedial recommendations, and records suitable for audits.

Typical activities include insulation resistance, pressure and sheath testing (where applicable), primary and secondary injection tests, protection relay checks, earth resistance testing, power quality reviews, and thermal imaging to identify issues before they become faults.

Safety & Compliance

Safety is our top priority. We operate with robust RAMS (Risk Assessments and Method Statements), isolation and permit systems, competency-verified engineers, calibrated equipment, and full compliance with relevant UK regulations and industry best practice.

We plan shutdowns to minimise disruption and, where appropriate, schedule works out-of-hours. We only proceed when safe systems of work and permits are in place.

Yes. Our engineers are fully trained and certified for HV/LV works, and we maintain appropriate insurances for the activities we undertake.

Maintenance & Reliability

Yes. We build PPM schedules tailored to your assets—switchgear, transformers, protection systems, earthing, and cabling—helping extend asset life, maintain compliance, and reduce unplanned outages.

Maintenance is planned activity to keep systems in good condition. Remedial works correct issues found during inspections, testing, or faults—such as defective joints, ageing components, or damaged terminations.

We focus on condition-based maintenance, thermal imaging, and targeted remedials, plus rapid-response fault finding, to keep your site online and safe.

Projects, Pricing & Process

We provide transparent, competitive quotations based on scope, complexity, materials, and access constraints. For ongoing needs, we can offer frameworks or service level agreements (SLAs).

Yes. We use approved components and OEM-recommended materials to ensure reliability, warranty validity, and compliance.

Yes. We coordinate with facilities teams, landlords, principal contractors, and relevant network stakeholders, and can support the permit process required for safe execution.

Documentation & Aftercare

You’ll receive test certificates, commissioning records, inspection reports, as-built drawings (where applicable), asset registers, and maintenance recommendations to support compliance and audit trails.

Yes. We provide warranty coverage on workmanship and materials (terms vary by product and project) and offer ongoing maintenance to protect your investment.

Sectors & Capability

Renewable Energy – wind farms, solar farms, battery storage

Warehousing & Distribution – large logistics hubs and DCs

Commercial & Industrial – offices, manufacturing, and estates

Retail & High Footfall Venues – safe, reliable power for operations

Yes, subject to a suitable shutdown strategy and stakeholder coordination. We often deliver phased programmes or off-peak works to keep critical operations running.
