Metering & Electrical Monitoring

Your electricity meter shows what you're consuming. Modern meters measure kWh (energy), kW (power), power factor, and reactive power. Older meters just show kWh; newer ones transmit data wirelessly.

Data collection frequency matters: daily is basic, hourly is good for spotting anomalies. Install sub-meters (200-500 GBP each) on HVAC, lighting, and major loads to pinpoint waste.

Power quality issues like harmonic distortion can waste energy and damage equipment. Plot consumption over time to find patterns, peaks, and anomalies.
