Regional HV Manager

High Voltage Manager

Hertford £80,000–£95,000 + Package

You’ve spent years being the person trusted to make the call before an HV system is switched, isolated or energised.

The next step doesn’t have to mean spending the rest of your career carrying out the switching yourself.

This role takes that SAP experience and puts it at the centre of how a growing data centre contractor manages High Voltage across its projects.

You’ll become the technical authority for HV within the business, establishing the standards, procedures and competency framework that sit behind safe electrical delivery rather than simply operating under somebody else’s.

Based from the Hertford office, you’ll work across a portfolio of data centre projects, supporting project, construction and commissioning teams from installation through energisation and handover.

The role is particularly suited to someone who has operated as an SAP and understands what good HV governance looks like in practice, but now wants a wider management position covering people, processes, projects and technical standards.

The business delivers data centres from design and construction through M&E installation, commissioning and managed services, so your involvement won’t start when a facility becomes operational.

You’ll influence how HV systems are planned, installed, energised and ultimately handed over.

What you'll do

• Take overall responsibility for High Voltage standards and governance across multiple data centre projects

• Develop, implement and maintain company HV electrical safety rules, procedures and safe systems of work

• Provide technical leadership to SAPs, APs, project teams and electrical management

• Assess and oversee the competency and appointment of authorised electrical personnel

• Review and approve HV switching schedules, isolations and energisation strategies

• Provide oversight of permit-to-work and electrical safety documentation

• Support project teams during HV installation, testing, commissioning and energisation

• Review electrical RAMS, switching plans, SOPs, MOPs and EOPs

• Provide senior technical support during shutdowns, faults and abnormal operating conditions

• Lead or support root-cause investigations following electrical incidents or failures

• Audit projects, electrical contractors and authorised personnel against company standards

• Work with Construction Managers, Project Managers and Commissioning Managers to ensure HV risks are identified early

• Support the selection and management of specialist HV subcontractors

• Mentor and develop SAPs, APs and other electrical personnel within the business

• Maintain awareness of changes in HV legislation, standards and industry best practice

• Help build a consistent HV operating model across a growing UK and international data centre portfolio

What you'll need

• Significant High Voltage electrical experience within data centres, critical infrastructure or similarly complex environments

• Current or previous Senior Authorised Person status

• Strong practical understanding of HV switching, isolation, energisation and permit-to-work systems

• Experience working with HV/LV distribution systems, transformers, switchgear, UPS and generators

• Experience supporting commissioning and energisation activities

• Strong knowledge of electrical safety rules and safe systems of work

• The ability to assess competency and provide technical guidance to SAPs and APs

• Experience managing contractors, technical teams or electrical operations

• Strong communication skills and the confidence to challenge project teams where electrical safety or technical standards are at risk

You don’t necessarily need to be looking for another SAP position.

In fact, this role is better suited to someone who has already done that job and wants to use that experience at a higher level.
