What is a half hourly meter and how do I know if I have one?

A half hourly meter, often abbreviated as “HH”, is a type of electricity or gas meter which measures and records the amount of electricity consumed by a business every 30 minutes.

This type of meter provides highly detailed and accurate consumption data by comparison to traditional meters that typically measure usage on a daily or monthly basis.

Half hourly meters are usually a key component in detailed energy management strategies.  Many monitoring and targeting technologies rely on HH meters being installed in order to build a clear enough picture for software to display accurate trends.

This improved accuracy also applies to billing, as well as management.

In the United Kingdom, the requirement for certain non-domestic consumers to use half-hourly meters is outlined in the Balancing and Settlement Code (BSC). These regulations are part of the broader framework for electricity supply and management in the UK. The key driver behind mandating HH meters is to gather accurate and timely consumption data to support the efficient operation of the electricity grid and facilitate market transactions.

Under these pieces of legislation, larger industrial and commercial customers previously using max demand meters (classes 05 to 08) are required to have HH meters.

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

The easiest way to determine if your meter is half hourly is to check your meter point reference.  This is your MPAN for electricity meters and MPRN for gas meters.  They can easily be found on your energy bill.

Your profile class on your MPAN will typically start with “00” if your electricity meter is HH.

Your profile class on your MPRN will typically start with “1” if your gas meter is HH.
