How Do Half-Hourly Meters Work?

Half hourly meters utilise a technology called AMR (automatic meter reading) to connect you with your utility company.

The meter sends half hourly electricity consumption data to your supplier so they can accurately bill you. The technology uses a fixed line, so unlike smart metering, it isn’t reliant on a home area network or wide area network.

What are the benefits?

One of the biggest concerns business owners have with regards to electricity is whether they’re being fairly charged for it.

If you share the same concern, half-hourly meters solve the problem by sending updated meter readings to your supplier every half hour.

This ensures your business pays the correct amount for electricity at all times with no discrepancies in data.

It also eliminates the need for your business to send meter readings to the supplier, as well as the need for the supplier to send someone around to check the meter, which makes for a better relationship between you and your supplier.

Another benefit of half-hourly meters is insight. With HH metering, you can monitor your electricity consumption and better understand how you are using electricity. This can help you put in place an energy reduction plan.

Do I need a half-hourly meter?

Depending on your electricity consumption, a HH meter can be either compulsory or voluntary.

For businesses who consume 100kW or more during any half hour period, a half-hourly meter is compulsory by law. Businesses who consume less than this can opt in to have a half-hourly meter installed by their supplier.

It’s also compulsory that businesses supplied in profile classes 05, 06, 07 and 08 with a meter capable of recording HH data be settled as half-hourly. This is the result of changes made in 2017 by P272, which you can learn more about here.

So, here’s the bottom line: your business will need a half hourly meter if it consumes more than 100kW in any half hour period – OR, if you are renewing your contract and your existing meter sits in profile classes 05, 06, 07 or 08.

Anything else I need to know?

Your current electricity supplier may not provide half-hourly metering, which could represent a problem if your energy needs grow.

Getting a good deal on half hourly metering can be a more complex process than with a standard meter. This can be because of fluctuating wholesale electricity prices, contract terms, time of year and the location of your business. A broker will prove valuable in helping you get a good deal by negotiating on your behalf.
