On 23 February 2026, OPITO published the official launch of its High Voltage qualifications framework. It introduces a progressive training suite designed to develop specialist electrical competence in high-voltage environments.
This new set of qualifications includes:
- High Voltage Training Certificate
- High Voltage Advanced Training Certificate
- High Voltage Control Training Certificate
Each certificate forms part of a structured learning route. All learners begin with core foundational knowledge and may progress to more advanced operational roles.
Every certificate represents around 280 guided learning hours and sits at recognised educational levels (SCQF Levels 7 and 8), confirming global training compatibility.
These qualifications were developed in consultation with industry experts and informed by wider energy transition foresight work. They are underpinned by established standards such as EN 50110 and aligned with recognised safety frameworks from leading associations.
Why High Voltage Skills Matter Now
Industry Electrification Is Rapid
Offshore energy systems are becoming increasingly electrified. Wind farms, floating assets, and offshore platforms all operate at higher voltage levels than ever before. This shift increases the technical complexity of installations and the importance of safe HV operations.
Global energy objectives mean the industry must expand HV capability to support large-scale power transmission from offshore assets to onshore grids. Without trained HV specialists, project delivery slows and risk increases.
Standardised training helps ensure consistent competence across regions and operators — which boosts safety and operational reliability.
Meeting the Skills Gap
Shortage of Specialist HV Workers
Employers worldwide struggle to find personnel capable of handling complex electrical infrastructure in offshore environments. The rapid expansion of offshore wind, combined with legacy oil and gas assets requiring enhanced electrification, increases demand for qualified technicians.
Without recognised training standards in HV competence, skilled workers often repeat training when moving between jobs. The new OPITO qualifications create a transferable, global standard that improves workforce mobility and reduces redundant training costs.
Industry Demand for Consistent Competence
HV systems involve high-risk operations such as electrical isolation, switching, and coordination with network operators. Mistakes can lead to serious safety incidents and costly downtime. A structured training framework helps organisations reduce those risks by ensuring competence before authorisation.
Standardised qualifications allow employers to confidently identify certified personnel who meet global HV competence expectations.
Qualification Levels Explained
1. High Voltage Training Certificate
This foundational route builds essential HV knowledge for technicians entering specialist areas or moving into offshore roles. Practical competencies include switching basics and safe isolation procedures.
It suits those preparing to work under supervision or assist in HV work.
2. High Voltage Advanced Training Certificate
This level expands on core skills and prepares learners for more complex HV tasks, especially where detailed planning and decision-making occur. It is ideal for senior technicians or supervisors who manage HV operations.
3. High Voltage Control Training Certificate
This highest tier prepares individuals to act as Person in Control of Electrical Installation (PCEI). It focuses on HV switching programmes, permit coordination, and leadership in HV environments.
Together, these certificates form a clear progression pathway from initial HV training up to advanced operational authority.
How Offshore Employers Benefit
Employers gain measurable advantages from adopting the new OPITO HV qualifications:
- A standardised benchmark for HV competence
- High-quality training that aligns with safety norms
- Better workforce mobility and recruitment clarity
- Support for compliance with regulatory and insurance requirements
Large operators, especially in offshore wind, now recognise the need for certified HV personnel as part of project execution and risk management.
Training Delivery and Availability
Approved training centres deliver these qualifications globally. They combine classroom learning, technical simulation, and real-world assessment to build competence that companies can trust.
Training delivery often includes both theory and hands-on scenarios that mirror offshore complexities, such as turbine and substation isolation procedures.
