Half Hourly Meters From UK Suppliers
What is a Half Hourly Meter?
Half hourly electricity meters automatically submit a reading every 30 minutes. For businesses with a peak demand of 100 KVA of electricity in any half-hour period, it is a legal requirement to have this type of meter. You will be able to find this information on a recent electricity bill.
Despite not being a legal requirement, companies that have a peak demand above 70 KVA but below the high consumption threshold see benefits of a half hourly meter.
Having a half hourly meter in place also unlocks tailored business electricity tariffs that are designed to fit exact requirements in terms of consumption, monitoring and insights.
Your electricity meter will have half hourly capabilities if it has a “00” in the top corner next to an S.
Do I Need A Half-Hourly Meter?
Half-hourly manage business electricity for large consumption users. Businesses with a peak electricity demand of 100 kilovolt amperes (KVA) or more must install a half-hourly meter.
Larger businesses using lots of electricity can cause difficulties when measuring usage with a standard or even a smart meter. Half-hourly customers are billed using data every 24 hours with readings recorded every 30 minutes. This helps identify electricity wastage to the hour and day to become more efficient, save money and ensure that bills are correct.
Benefits Of A Half-Hourly Meter

How Do Half-Hourly Meters Work?
Half-hourly meters send readings to your supplier every 30 minutes using an AMR (automatic meter reading) system to ensure billing remains accurate. This system uses a fixed phone line or a mobile signal depending on your half-hourly meter set-up. There’s no need to take any manual readings.
Half-Hourly Meter Readings
You do not need to perform meter readings on half-hourly meters as they are automated and sent directly to your energy supplier. There may be an occasion where your supplier might need to ask you to supply a manual meter reading on your half-hourly meter reading. This will be done the same way as any digital meter.

Can Any Business Get A Half Hourly Meter?
No. Half-hourly meters are only available to UK businesses with a peak demand of 70KVA in a single 30-minute period. Some businesses sitting around these peak demands often choose to get a half-hourly meter before they hit the mandatory threshold of 100KVA of peak demand due to the benefits.
What Does P272 Mean?
P272 refers to a piece of legislation passed in 2014 to phase profile class meters from 05 to 08 that had to be moved to a half-hourly meter.
This officially became mandatory in 2017 to help businesses and suppliers properly manage high-consumption electricity usage. This ensures that every business in this profile class is billed for the actual amount of electricity they have used and is not wrongly estimated. As the usage is high, estimated billing can cause serious cash flow problems.
