Half-Hourly Meter

Key takeaways

A half-hourly meter records electricity consumption every 30 minutes (48 periods per day).

That gives suppliers a more detailed view of how you use electricity, which can affect pricing and billing accuracy.

What is a half-hourly meter?

A half-hourly (HH) meter is an electricity meter that records your consumption in 30-minute blocks.

It allows your supplier to get an accurate picture of use based on real-time energy use.

Why HH metering matters

Because your usage is recorded in detail, HH metering is often linked to:

1. more accurate bills
2. more detailed analysis of peaks and patterns
3. greater importance of how and when you use power (not only how much)
