With more than 45,000 specialists globally, the team enables clients to enhance the performance of their real estate portfolios and people to realize their ambitions for a more sustainable built environment.
The role
At JLL, our Engineering teams support some of the most complex and safety‑critical environments in the UK. We are now seeking an experienced HV Engineer to play a key role in delivering safe, compliant, and resilient electrical operations across the Rolls‑Royce UK estate.
This is not a standard electrical engineering role.
It is a formally authorised, safety‑critical position with responsibility for controlling and authorising work on high‑risk electrical systems.
The Role
As an HV Engineer, you will act as the Electrical Authorised Person (HV/LV) for designated Rolls‑Royce sites, based on Derby and supporting locations across the UK.
You will hold authority for the safe isolation, switching, and authorisation of High Voltage and complex Low Voltage systems, ensuring all works are delivered in full compliance with the Safe System of Work, Electrical Safety Rules, and statutory requirements.
Alongside this authority role, you will remain technically engaged—supporting projects, maintenance, fault diagnosis, inspections, and asset reliability across a highly critical environment.
Key Responsibilities
Act as the Electrical Authorised Person (HV/LV) within your defined area of appointment
Control and authorise work on HV, LV, and complex LV electrical systems
Prepare, review, and check HV switching programmes and safety documentation
Undertake isolations, proving dead, restoration of supplies, and transfer of control
Issue, control, suspend, and cancel permits to work and safety documents
Verify the competence of the Person in Charge (PiC) and monitor works on site, stopping work immediately if safety is compromised
Provide training and mentorship to new and existing competent persons
Review and approve RAMS for high‑risk electrical activities
Act as Duty Authorised Person when appointed, maintaining system oversight, and manage access to high-risk infrastructure
Provide technical leadership during outages, shutdowns, critical works, and project works
Diagnose complex faults and support planned and reactive maintenance activities
Ensure inspections, testing, and remedial actions meet statutory and client standards
Maintain accurate records, schematics, and asset documentation
Promote a strong safety culture, including stop‑work authority where required
What We’re Looking For
Essential
Electrical trade qualification or engineering qualification (UK‑recognised or equivalent)
Proven experience working with High Voltage and complex LV electrical systems
Currently appointed as an Electrical Authorised Person (HV/LV) or demonstrably capable of assessment
Strong knowledge of Safe Systems of Work, Permit to Work, and isolation procedures
18th Edition Wiring Regulations
C&G Level 2 & 3 Electrical Installation or equivalent
Full UK driving licence
Willingness to travel UK‑wide and work flexibly for critical operations
Desirable
Test and inspection certification
Experience supporting HVAC electrical interfaces
Familiarity with critical or regulated environments
First aid qualification including resuscitation

Why Join JLL?
Work in a senior, safety‑critical engineering role with real authority
Support one of the UK’s most prestigious and complex client estates
Clear pathways for progression within Authorised Person, Senior HV, and AE‑track roles
Strong professional governance, training, and support
