Domestic and business premises have different meters. This is because business electricity usage is different from that of domestic customers.
Your meter will have a profile number and can be found on your energy bill:
Energy profile numbers and what they mean.
In rare cases, some businesses may have domestic 01 (domestic unrestricted) and 02 (domestic economy 7) meters. Only a handful of energy providers will provide commercial energy contracts to these businesses.
Standard business meters:
Typical commercial meters begin 03 or 04 and will pay standing charges, unit rates and a Climate Control Levy (CCL).
03 - Non-domestic unrestricted
Standard 03 meters use one unit rate when measuring usage. This means that the rate you pay for each unit of energy used will remain the same throughout the day, regardless of time. This type of unit is best suited to those businesses with low energy consumption.
04 - Non-domestic economy 7
This is a two-rate business energy meter. This means you pay a day rate and an evening rate on the energy you use. Electricity rates are usually higher during peak times and lower at night times. It is advisable to check with your supplier to confirm what time their economy 7 hours apply. Most suppliers operate their economy 7 hours between 1pm and 8am, though this can vary depending on supplier and location.
Maximum demand meters
Maximum demand meters are those with the following profile numbers:
Businesses who have these types of meters often have high levels of energy consumption. Much like the standard meters above, there are two options available:
- Maximum demand 1 rate meter - charges a single rate, regardless of the time of day
- Maximum demand 2 rate meter - charges a day and night rate, with cheaper rates running during off-peak hours
As part of P272, half-hourly meters have been introduced to provide more accurate billing for businesses and help prevent businesses from overspending on electricity.
As opposed to previous maximum demand meters, where units are measured every hour, new 00 meters (also referred to as HH meters) measure units every half hour. This will help provide accurate energy insights to your supplier.
These meters are mandatory for customers with an energy demand greater than 100kW, though customers can request a half hourly meter if their consumption is greater than 70kW.
