Safe. Compliant. Continuity You Can Count On.

At HaLVE, we offer bespoke Control, Operation & Maintenance Agreements (COMA) for High Voltage (HV) and Low Voltage (LV) electrical systems—ensuring your critical infrastructure is safe, reliable, and fully compliant with industry standards and healthcare-specific guidance.

What Is a COMA?

A COMA is a formal agreement in which HaLVE takes responsibility for the control, operation, and maintenance of your electrical systems. This is especially vital in high-dependency environments such as hospitals and industrial plants, where uptime and compliance are essential.

Regulatory Compliance

We align every COMA with the latest UK legislation and guidance, including:

  • Electricity at Work Regulations 1989 – Requiring all electrical systems to be maintained to prevent danger and operated by competent persons.
  • HTM 06-03 – Outlining safety-critical requirements for the design, operation, and maintenance of electrical systems in healthcare settings.

What’s Included

  • 24/7 emergency response with direct access to qualified engineers
  • HV/LV switching operations and isolation procedures
  • Planned Preventative Maintenance (PPM)
  • Transformer Oil Sampling for insulation health and early fault detection
  • TEV Testing to detect partial discharge and mitigate switchgear failure risk
  • Compliance audits, documentation, and lifecycle planning
  • Coordination with Distribution Network Operators (DNOs)
  • Dedicated Maintenance Team assigned to your site for consistent, knowledgeable support
  • Customer Portal Access – download reports, certificates, and maintenance logs at your convenience

Who We Support

  • NHS Trusts and private healthcare providers
  • Manufacturing and heavy industry
  • Education campuses and local authorities
  • Commercial facilities and estates teams
