Following an industry-wide consultation, the UK gas and electricity regulator, Ofgem, has introduced new metering legislation known as ‘P272’.

What is P272?
Following an industry-wide consultation, the UK gas and electricity regulator, Ofgem, has introduced new metering legislation known as ‘P272’.

Under the conditions of P272 all electricity customers identified as profile classes 05-08 must use an accredited, automated meter, which is capable of sending regular half hourly data usage, allowing BES to provide you with more accurate billing information. This will also highlight when a business may be using more or less energy and if the usage is at peak or off-peak times, making it a valuable tool when making your business run more cost efficiently.

All profile classes 05-08 will be appointed a Meter Operator (MOP) and a Data Collector (DC). The MOPs and DCs will run and maintain your meter whilst communicating the readings to BES.

Will P272 affect me?
Your profile class can be found in the top left hand corner of your S (supply) number. Your S number can be found on your monthly invoice and will look like the below example. The example below is a profile class 05. If your S number shows either 05, 06, 07 or 08, then you will be affected by the changes P272 will bring.

What's your profile?

I have a Profile Class 05-08, what do I need to do?
From 05 November 2015, those customers with a profile class 05, 06, 07 or 08, which already have an accredited, automated meter reading (AMR) device will be billed and settled half hourly. Those customers with a profile class 05, 06, 07 or 08 and have a Current Transformer (CT) Meter will also be billed and settled half hourly. The exact date that your migration will happen will depend on your contract renewal date. All meters with a profile class of 05-08 must be settled half hourly by 01 April 2017 regardless of contract renewal date.

I have a Profile Class 05-08, but I don’t have an AMR, what do I need to do?
Please contact BES to arrange the installation of an AMR device. For BES customers, this service is free of charge.

I have a Profile Class 05-08 and an AMR, when is my migration date?
Your migration date depends on your contract renewal date. Your supplier has 45 days from your contract renewal, date or change of supply date, to go through the change of measurement class process, to update your meter to Half Hourly billing. This means your migration date is dependent on your contract end date or change of supply date.

For those customers whose contract end date falls after 01 April 2017, the change of measurement class process will be completed in migration batches, ensuring all are changed prior to the deadline date. If your contract ends after 01 April 2017, please contact BES for a migration date.

Do I need a MOP and DC?
Yes, to enable your supply to have Half Hourly data collected, you must have a MOP and a DC. You can appoint a MOP and DC yourself, however to make the process simpler, BES can appoint one for you, which has been the case prior to the Change of Measurement Class (CoMC) for most profile class 05-08 customers. If supplied by BES, you can contact us direct for further information on which companies provide these services.

What is my Maximum Import Capacity (MIC)?
Your Distribution Network Operator (DNO) will contact you, if they haven’t already. They will advise you of your Maximum Import Capacity (MIC) and any variances they have. You will then need to agree this or change it based on the information provided.

Can I move to Profile Class 03 or 04 to avoid P272?

ELEXON, the balancing and settlement code company that manages the electricity and trading arrangements for England and Wales, has had a number of queries raised regarding Metering Systems in Profile Classes 05 - 08 being downgraded to Profile Classes 03 or 04, rather than being migrated to Half Hourly Settlement under P272.

They have advised that if a Profile Class 05 - 08 MPAN has an advanced meter fitted (smart meter), then it must be migrated to Half Hourly Settlement in line with the P272 requirements, and cannot be moved to Profile Class 03 or 04 for the following reasons:

  • The Standard Licence Condition (SLC), section 12.17-12.22 states that, from 6 April 2009, any new sites that meet the Profile Class 5-8 definition in the BSC must have an advanced meter fitted.
  • Any existing Profile Class 5-8 sites at 6 April 2009 were required to have an advanced meter fitted by 6 April 2014.
  • Additionally, from 6 April 2014, any non-domestic premises with Current Transformer metering must have an advanced meter fitted.
  • From 1 January 2021, all premises with Current Transformer metering, whether domestic or non-domestic, must have an advanced meter fitted.

Where there is such a licence obligation, Suppliers must transfer existing Metering Systems to Half Hourly Settlement by 1 April 2017, as detailed in P272.
