What is a large energy user?

Bristol Energy consider a large energy user to be any business that is billed on a half hourly basis. Currently we have a 3 GWh per site consumption threshold, which equates to a maximum spend of approximately £300,000 each year.

If you have sites paying under the £300,000 pa threshold and have a half hourly meter (identifiable by its MPAN number that will have 00 as the profile class - the two digits at the top after the ‘S’), then we would love to speak to you about your supply.

What is a Half Hourly electricity meter?

A Half Hourly electricity meter is a specialised kind of business electricity meter. The meter is connected via a phone line and automatically sends updated meter readings to the energy supplier every half hour.

As a result there’s is no need for you to take and submit meter readings manually and the frequency of these automatic readings result in extremely accurate and up-to-date energy bills.

You can also get detailed breakdowns of when you are using the bulk of your business electricity so you can use this information to try and be more energy efficient and reduce your usage.

Does my business need a Half Hourly meter?

Half Hourly electric meters are used by larger, more energy intensive businesses, such as factories or large offices. 

If your business has a maximum demand of 100 kW or greater in any half hour period during the day then a half hourly meter will be compulsory for you. If you have a maximum demand of 70kW or more then you can opt to have a half hourly meter installed.

Does my business have a Half Hourly meter?

If you are in a new business premises then you can check if you already have a HH meter installed by taking a look at the 'S number' on a previous energy bill. If the number in the top left box is 00 then this is a half hourly meter.
