COP3 and COP5 Metering Panels

COP3 and COP5 Metering Panels

Understanding the Difference Between COP3 and COP5 Metering Panels – And Why They Matter

By NKD Group Limited

In today’s energy-conscious environment, accurate electrical metering is not just a regulatory necessity – it’s a business-critical asset. Whether you’re managing a commercial facility, a manufacturing site, or a large-scale infrastructure project, understanding the differences between COP3 and COP5 metering panels can help you stay compliant, optimise energy usage, and future-proof your infrastructure.

At NKD Group, we specialise in designing and manufacturing both standard and bespoke COP3 and COP5 metering panels, tailored to meet the unique demands of your project.


⚡ What Are COP3 and COP5 Metering Panels?

COP3 and COP5 refer to Codes of Practice defined by the UK’s Balancing and Settlement Code (BSC), which governs the accuracy and specification of electricity metering systems used for billing and energy settlements. These standards ensure metering equipment meets the correct levels of performance, accuracy, and reliability.


🔹 COP3 – For High-Load Commercial and Industrial Applications

COP3 metering panels are designed for large commercial or industrial premises, particularly those with energy usage exceeding 100kW. These panels are:

  • CT-operated (Current Transformer)
  • Installed on low or high-voltage systems
  • Highly accurate, with an overall performance of ±1.0%
  • Used in scenarios where energy usage data is used for financial settlement or regulatory reporting

Applications: Factories, substations, infrastructure hubs, large office buildings, solar farms, and other high-demand environments.


🔹 COP5 – For Smaller Commercial Installations

COP5 metering panels are suitable for smaller commercial or light industrial sites with energy consumption typically below 100kW. These are:

  • Either whole current or low-burden CT operated
  • Less stringent in terms of accuracy (±2.0%)
  • Often used where metering is required for operational insight rather than regulated settlements

Applications: Retail units, small offices, workshops, and other low-load installations.


🧠 Why Accurate Metering Matters

Using the correct metering solution is vital for:

Regulatory compliance under the BSC

Accurate billing and prevention of energy overcharges

Load management and energy efficiency planning

Grid transparency, especially when exporting to or drawing from the grid

Data integration with Building Management Systems (BMS) or SCADA platforms

Incorrect metering can result in billing disputes, compliance failures, and lost financial opportunities.
