Which energy meter is right for your business?

Written by Michael Potts | Aug 17, 2026, 3:00:22 PM

Every business relies on energy meters, but not every business has the same type.

Understanding the difference between non-half-hourly, half-hourly, smart and advanced meters can help you avoid billing issues, understand your energy usage and make better energy purchasing decisions.

The good news? You don't need to become a metering expert. You simply need to understand which meter you have and how it affects your business.

In this article:

  • Learn what business energy meters do and what types of meters exist.
  • Understand the benefits and issues of different meters.
  • Discover practical ways to use meters to your advantage.

What does a business energy meter do?

Business energy meters measure how much electricity or gas your business uses.

That information is used by suppliers to calculate your bills and, depending on the type of meter, can also provide valuable insight into how and when your business consumes energy.

Manual meter readings were traditionally taken at intervals to periodically update your bills, but the adoption of smart meters means data is automatically sent to suppliers on a much more frequent basis.

The more accurate your usage data, the easier it becomes to understand consumption patterns, manage costs and choose the right energy contract.

What types of business energy meter are there?

Non-half-hourly (NHH)

  • Used by: Smaller businesses with lower electricity consumption.
  • Measures: Total electricity usage between meter readings.
  • Benefits: Simple, cost-effective and suitable for lower energy users.

Half-hourly (HH)

  • Used by: Larger businesses with higher electricity demand.
  • Measures: Electricity usage every 30 minutes.
  • Benefits: More accurate billing and detailed consumption data for energy management.

Smart meters

  • Used by: Businesses of all sizes.
  • Measures: Automatic meter readings sent directly to your supplier.
  • Benefits: Eliminates estimated bills and provides greater visibility of energy usage.

Advanced meters (AMR)

  • Used by: Medium and large commercial premises.

  • Measures: Automatic remote meter readings.

  • Benefits: Improves billing accuracy and simplifies energy monitoring without manual readings.

How can I tell which business energy meter I have?

Not sure which physical meter your site has installed? Here are a few tips to identify your meter:

Traditional meters: Usually feature moving dials with a requirement to take manual readings. Some may show a very basic screen.

Smart meters: Usually features an electronic screen with no moving parts or rotating wheels. It may also be attached to a small communications hub with a flashing light.

If you're unsure, your supplier or energy consultant can confirm which meter type is installed and whether readings are sent automatically.

Why should businesses consider a smart meter?

There are three key benefits to having an operational smart meter monitoring your business energy usage:

  1. Automatic readings: No more reminders to submit a reading manually. No more accidentally plugging in the wrong numbers or scrambling to find the meters on multiple sites.
  2. Actual readings: If you miss a manual meter reading submission, your bill could be based on an estimate. Smart meters ensure you will generally always receive a bill based on actual data.
  3. Better insights: A traditional meter can only show you how much energy you use between readings, which may be taken at irregular intervals. Smart meters are able to break down usage patterns so you can spot trends more easily.
