What is a half-hourly electricity meter?
A half-hourly electricity meter, also known as a HH or 00 meter, automatically measures and records energy usage for businesses every 30 minutes. It works using automatic meter reading (AMR) technology to provide more accurate readings than non-half hourly meters.
Similarly to a smart meter, a half-hourly meter takes your reading and transmits it via a phone connection. This is ideal when it comes to highlighting what times of the day are costing your business the most amount of money when it comes to your electricity consumption.
Generally, half-hourly contracts will range from 1 to 3 years in length.
Do I need a half-hourly meter?
Half-hourly meters are mandatory for any businesses in the UK that use at least 100,000 kWh of electricity each year. If your business has an 05, 06, 07 or 08-meter profile, you need a half-hourly meter. This is due to the P272 regulation that was approved by Ofgem in 2017.
The P272 regulation requires companies in electricity-intensive industries (EIIs), such as manufacturing and food processing, to move from non-half hourly meters (NHH) to half-hourly meters (HH). Moving to half-hourly meters allows suppliers to keep better track of customer energy usage.
With more accurate measurements, suppliers can purchase electricity from the grid more economically, so customers aren’t overcharged for their energy and everyone benefits from the regulation.
How do I know if I have a half-hourly meter?
To find out what kind of meter you have, look at the MPAN number on your last energy bill. The MPAN number can be found on the top left of your bill to the right of the S.
If your MPAN number is ‘00’, you have a half-hourly meter. If the number is 05, 06, 07 or 08, you’ll need to upgrade to a half-hourly meter as soon as you can.
How do you read a half-hourly meter?
Half-hourly meters are automatic, so they don’t need to be read manually. Readings are taken every half-hour, totalling 48 per day. The system relies on a fixed line that
updates your supplier with automatic meter readings in half-hour periods. With updates in real time, suppliers can create highly accurate charges to make sure you’re paying for exactly how much energy you use.
What are the benefits of a half-hourly meter?
The most immediate benefit you’ll notice from a HH meter is that all energy readings are automatic, meaning you’ll never need to go through the trouble of recording or sending your readings to your supplier.
Half-hourly meters also give you the opportunity to save money on your energy bills. You can review exactly when your business uses the most energy by analysing your consumption data and work towards operating more efficiently, which will save money on your bills.
Please note that lower bills aren’t guaranteed: they rely on your actions as a business owner.
