Charge Codes and Switch Regimes

A Charge code is a 13 digit number assigned to apparatus that UMS Customers wish to add to their inventories. Guidance on the new 13 digit format, implemented in June 2008 is set out in the  New Charging Code Structure for Unmetered Supplies Guidance Note. Charge codes are used within the UMSO systems to calculate volumes of electricity consumed. If you use a piece of equipment, it must go on the inventory with a charge code. The application procedure for a charge code for a new piece of equipment is detailed in the Operational Information document in the table below.

The charge codes in the Unmetered Supplies Operational Information document are no longer contained within a Code Subsidiary Document. No BSCP520 appended documents will be produced.

If the charge code you need is not listed in the document below, please apply for one, as laid out in the testing procedure in the  Overview of the UMS Charge Code Process document.

Please download a copy of the UMS Charge Code Application Checklist from the table below. You must complete this form and send it with your application.

What is a Switch Regime?

A Switch Regime is a three digit numeric code for any Unmetered Supply equipment identifying the number of hours that the equipment will be operational. It also details the on/off times of the equipment.

The application procedure for a switch regime is the same as that for charge codes.

Charge Code / Switch Regime Application Schedule

The dates below are deadline dates for all charge code and switch regime applications, as well as the dates all application responses will be sent to applicants. We reserve the right to change these dates if necessary. You must send your applications ahead of the deadline dates to allow adequate time for initial review.

* Applications received earlier in each cycle allow more time for processing and initial reviews to be completed ahead of the deadline date, resulting in a greater likelihood of having a successful application that month.
