Ofgem legislation P272 requires all Maximum demand meters within profile class 5-8 which have an automatic meter reading meter fitted to be settled on actual half hourly consumption data.

The proposal is aimed at moving the roll out to April 2017, it was originally proposed for April 2016.

What is P272 and who does it affect?

P272 is a proposal to change the Balancing and Settlement Code in order to make settlement more accurate. The change will affect an estimated 160,000 meters across the UK.

By April 2017 all customers with a meter Profile Class 5 to 8 (also known as Maximum Demand sites) and an Advanced Meter Reading (AMR) meter installed will need to be settled half hourly.

Does it affect me? It affects end customers who have meters that are Profile Class 05-08. To find out if you have one of these, you can check your bill. In this example, the Profile Class is 05:

Maximum demand meter example

The introduction of P272 means that if your organisation has any advanced Non Half Hourly (NHH) electricity meters these will now need to go through a Change of Measurement Class (CoMC) to Half Hourly (HH) Settlement. 

Why is P272 happening?

P272 means that the industry should use half hourly data for /settlement/ in order to improve accuracy. It will also help distributors better understand electricity usage, so that they can make sure networks are maintained appropriately.

‘Settlement’ refers to how suppliers match and pay for the energy consumed by customers, to the energy purchased on their behalf.

For non-half hourly sites, consumption is profiled across the industry, based on what a typical customer in a relevant Profile class uses. This means that suppliers must obtain meter readings before they can ‘settle’ based on actual consumption.

For half-hourly sites, the meters record consumption every half an hour, rather than waiting for meter readings. This means suppliers can settle their consumption based upon actual usages and be able to offer pricing and products that reflect half-hourly costs and consumption more closely in the future.

What does this mean to Maximum demand users?

As P272 will measure energy usage based on half hourly readings, this will allow suppliers to price your contract based on your actual consumption pattern and also provide you with a bill that better reflects the actual cost of your energy. Half hourly data allows a supplier to use historical data, meaning that any customers who reduce energy consumption at peak times (for example early in the morning and late afternoon, particularly in winter) will see a reduction in their unit rate when they come to negotiate their next contract.

Will P272 mean I will need to replace my meter?

The majority of customers who are affected by P272 will not need to have a new meter installed. If your AMR is able to be configured remotely it will already be capable of taking the HH readings and it will be unlikely that you will need to have your meter replaced.

What do I have to do?

You are required to appoint a Meter Operator (MOP) and Data Collector (DC), Energy Procurement can help with this process.

End customers will then move from monthly Meter Reads and billing to Half Hourly (HH) billing and Settlement as part of the Change of Measurement Class (CoMC) process.

How we can help

The Change of Measurement Class (CoMC) process is complex and can be very confusing for both customers and energy suppliers, Energy Procurement can help by offering full end to end management of the P272 changeover process and ongoing Meter Operator (MOp), Data Collector (DC) / Data Aggregator (DA) and D+1 Data services.
