Half Hourly Electricity Meters


When you run a large business with high energy consumption, half hourly metering is something you need to know about. Here, we’ve answered a few questions you may have about half hourly electricity meters and how they work.

What is a half hourly meter?

A half hourly meter, as the name indicates, measures how much electricity is being used every half-hour. This type of meter is linked to a communications device which allows its readings to be sent to the energy supplier at the end of each half-hour period.

What are the benefits of a half hourly meter?

Because readings are automatically taken and transmitted so frequently, having this type of meter ensures your energy bills are very accurate rather than being based on estimations. The detailed information the meter gathers about your electricity use also makes it very easy for you to track the effects of any energy efficiency measures you put into place.

Does my business need a half hourly meter?

Half hourly meters are mandatory for businesses with a peak electricity load of 100kW or more in any single half-hour period. Businesses with a peak electricity load of more than 70kW have the option of having one installed, but are not required to do so.

How do I know if I have a half hourly meter?

There’s an easy way to identify if your business has this type of meter – simply check the Supply Number on the most recent electricity bill for the premises. If that number begins with ‘00’, you have a half hourly meter installed. It’s a good idea to check this number when moving into new premises.

Can I switch my half hourly business energy tariff?

While switching a half hourly tariff can be more of a complex process than switching a regular tariff, it can certainly be done. The easiest way to explore your options is to discuss your requirements with an impartial energy broker like SwitchMyBusiness.com.
