Half hourly (HH) electricity metering is an essential part of large business electricity usage monitoring. Designed to give the most accurate readings, it can help your company save money in the long run.
Here’s our handy guide on how it works, who needs it, and how it can save you money.
Half hourly meters (also known as 00 meters) do exactly what you think; measure your business’ electricity usage every 30 minutes. This data is recorded and sent to your provider automatically, helping give an incredibly accurate picture of your energy usage.
Half hour electricity is mandatory in the UK for businesses using at least 100,000 kWh every year. This includes, but is not limited to, manufacturing plants, printers, and assembly plants. Some businesses with lower consumption can also opt for an HH meter, because of the accuracy of the readings.

Due to the fact that every business has different energy consumption requirements, it’s difficult to provide an accurate and informative picture of what an “average” unit price would be. We can, however, offer tips on how to go about searching for the best HH business energy deal for your premises.
