Carrying out a range of engineering work on power protection systems, plant and equipment.
Apprentices learn to test, commission, and verify electrical protection systems and power plant equipment across generation, transmission, and distribution networks. The programme covers individual component testing through to full system commissioning, including making equipment live and monitoring its integrity at first energisation. Apprentices also develop skills in fault diagnosis, rectification, and providing technical support on operational procedures and compliance. Work must meet manufacturer specifications, company procedures, and relevant operating parameters, with safety, quality, and schedule requirements central throughout.
Working alongside qualified engineers, apprentices carry out pre-commissioning checks, functional tests, and protection relay settings verification on electrical plant and equipment, both new installations and refurbishments. A typical week might involve preparing test documentation, conducting secondary injection tests, completing switching operations under supervision, and recording results against acceptance criteria. Interaction with project managers, site supervisors, and clients is common, and apprentices may help schedule and prioritise commissioning activities as their confidence grows.
Completing this apprenticeship positions someone to work as a protection and commissioning engineer, site commissioning engineer, or field test engineer. With experience, progression into senior or lead engineer roles is achievable, as is moving into project management or technical consultancy. Employers span national grid operators, regional distribution network operators, power generation companies, and specialist commissioning and testing contractors. The skills are transferable across sectors that operate high-voltage infrastructure, including renewables, nuclear, and industrial power systems.
Sorted by achievement rate.
No training providers currently listed for this standard.
Completers typically move into Electrical Protection and Commissioning Engineer roles, working on live power infrastructure projects. Other immediate titles include Protection Systems Engineer, Plant Commissioning Engineer, and Substation Commissioning Engineer. Day-to-day responsibilities cover testing protection relays, witnessing factory acceptance tests, conducting site commissioning, and signing off equipment readiness. Some move directly into specialist contractor roles; others join in-house engineering teams within network operators or generation companies.
Within three to five years, engineers typically progress to Senior Commissioning Engineer or Lead Protection Engineer, taking ownership of larger projects and providing technical sign-off. Those who move into leadership can reach Commissioning Manager or Engineering Manager, overseeing teams and client delivery. The deep-specialist track leads toward Protection and Automation Consultant, Principal Engineer, or roles in protection system design and standards. Chartered Engineer status through the IET or IMechE is a realistic goal along either track.
The main employers are electricity network operators, power generation companies, and specialist high-voltage engineering contractors. National transmission and distribution network owners hire these engineers, as do independent commissioning contractors who work across multiple utilities. Roles also arise with equipment manufacturers supporting field commissioning and with major infrastructure firms delivering grid connection projects. Both the private sector and publicly regulated network businesses recruit at this level, and demand extends across Great Britain and into offshore generation projects.
Learning takes place alongside employment, with apprentices developing the knowledge, skills and behaviours needed for the role through real work on electrical power projects. Before final assessment, a readiness check, commonly called the gateway, confirms the apprentice and their employer are satisfied that the required competence has been demonstrated. Final assessment then provides independent confirmation that the apprentice can perform the role to the standard required, across areas such as commissioning, protection system testing, fault diagnosis and safe working. Assessment models for many standards are currently being updated, so check the standard's gov.uk page for the current specification.
Building a record of workplace evidence throughout the apprenticeship, rather than at the end, makes the final assessment process considerably more straightforward. This means keeping clear documentation of commissioning activities, test results, fault-finding work and any technical support provided to colleagues, all grounded in real projects. Working closely with both the employer and the training provider, and having honest conversations about readiness well before the gateway, gives the apprentice the best chance of completing confidently and on time.
Providers worth considering will have delivered this standard, or a closely related high-voltage or power systems standard, to apprentices working in generation, transmission or distribution environments rather than general electrical installation. Check the achievement rate on the FATP profile: above 65% is a reasonable baseline for a specialist standard of this complexity, and above 75% is strong. Look for employers listed as delivery partners, evidence that training facilities include protection relay test equipment and secondary injection test sets, and tutors who hold or have held relevant industry authorisation (such as Safety Rules Competence).
Be cautious of providers with a high volume of engineering apprentices but a thin or undisclosed cohort on this specific standard. If the achievement rate is declining year on year, ask why before committing. Providers who cannot explain how they cover protection schemes (overcurrent, differential, distance) in practical sessions, or who rely entirely on classroom delivery with no access to live or simulated high-voltage plant, are a concern. Vague answers about employer engagement during off-the-job training, or no clear process for site-based assessment sign-off, are warning signs worth taking seriously.
Employers set their own entry requirements, but candidates typically need a relevant Level 3 qualification in electrical engineering or a related subject, or equivalent practical experience in an electrical environment. A strong grounding in electrical principles is important given the technical complexity of protection systems and high-voltage plant. Some employers may accept equivalent industry experience in place of formal qualifications. Check with individual training providers, as entry criteria vary.
The typical duration is 36 months, though the actual time depends on the apprentice's prior experience and the employer's programme. The apprentice is employed throughout and applies learning directly to live commissioning and testing work. Off-the-job training is built into the working week. Specific minimum duration requirements and off-the-job training proportions are subject to ongoing revisions under Skills England reforms, so check the current specification on gov.uk for up-to-date details.
Before reaching the end-point assessment, the apprentice must pass through a gateway, at which point the employer and training provider confirm the apprentice has demonstrated the required knowledge, skills and behaviours. Assessment models for many standards are currently being updated under Skills England reforms, so the specific methods used, whether that involves a practical observation, professional discussion, or written assessment, may change. Always check the current assessment plan on gov.uk before enrolling.
The funding band for this standard is £27,000, which is the maximum that can be drawn from the apprenticeship levy or government co-investment. Large employers with a levy account use those funds directly. SMEs without a levy account typically pay 5% of the training cost, with the government contributing the remaining 95%. Employers with fewer than 50 staff taking on a 16 to 18-year-old apprentice pay nothing. Speak to a training provider to confirm current funding rules and eligibility.
The work centres on testing and commissioning electrical protection systems and power plant, from individual component checks through to full system sign-off. This includes making equipment live, monitoring its performance on first energisation, diagnosing faults, and rectifying problems. The apprentice will work across generation, transmission, or distribution environments, follow strict safety procedures, and support other engineers with technical guidance on compliance and operating procedures. Scheduling and prioritising tasks on live projects is also part of the role.
Completing this apprenticeship at Level 4 provides a strong platform for progression into senior or lead commissioning engineer roles, project management positions within the power sector, or specialist roles in protection engineering. Some engineers go on to study for a Level 6 or Level 7 qualification to work towards chartered status with a professional body such as the IET. The skills gained are transferable across power generation, transmission, and distribution, which broadens career options considerably.
