This guide will help answer any questions you may have. It gives advice on how to bring down any costs brought about by the change. If you want more detailed information, please read our more detailed FAQs: BSC Modifications P272 and P322.
From 1 April 2017, all businesses in profile classes 5 to 8 were required to have their energy use recorded every half hour. This is part of a process called ‘settlement’.
These changes are due to a modification to the Balancing and Settlement Code called P272.
And, since 5 November 2015, every customer who renews or starts a new contract with a new supplier will have their energy use recorded half hourly and used in ‘settlement’.
This is due to another modification to the Balancing and Settlement Code called P322, which helps businesses & suppliers move to half hourly ‘settlement’.
These changes only apply to non-domestic businesses that are in profile classes 5-8 and have an advanced meter installed.
It applies to all businesses in profile classes 5-8 and who have an advanced meter installed. It’s up to the supplier to take all reasonable steps to ensure that businesses in profile classes 5-8 are supplied through advanced meters. This has been the case since April 2014.
Look at the Meter Point Administration Number/Supply Number on your electricity bill. If the first (two-digit) number in the box to the immediate right of the ‘S’, is 05, 06, 07 or 08, then the changes apply. Otherwise, if the number is 01, 02, 03, 04 or 00, it does not.
Industry are currently reviewing and amending their approach to downgrading to Profile Classes 3 and 4. This includes reviewing the rules under BSCP516. The following link provides further information. Please contact your supplier whilst the industry change process is ongoing.
No. The industry rules mean it is not possible to remain non half-hourly settled, if you are in profile classes 5-8 and have an advanced meter.
No. It’s only possible for you to be half hourly settled where your premises already has an advanced meter installed.
It’s up to the suppliers to take all reasonable steps to ensure that businesses in profile classes 5-8 are supplied through advanced meters. This has been the case since April 2014.
Suppliers are responsible for implementing BSC Modifications P272 and P322. If you are affected by the changes, then your supplier will have been in contact with you. The rest of this guide gives some advice on how this could affect your bill and how to get the best energy deal.
Many businesses will have seen either no change to their bills or they will have gone down under half hourly ‘settlement’.
However, some businesses may have been asked to pay more. This will have been because it will take up more time and resources for suppliers to collect and process your electricity use every half hour.
Also, if you have a Current Transformer (CT) meter, you may have seen an increase in your network charges. One of the main reasons for this increase will have been because you now face charges for the capacity the distribution network operator has reserved for you on their network.
In the future, we expect bills to go down as consumers take more control of their consumption, spreading their use out across the day not just in peak hours. This will bring down costs for network operators, enabling them to avoid future costs and reduce their charges.
Yes. When your contract is up for renewal it is the perfect time to shop around to get the best deal. You can:
You could pay less to use electricity off peak hours. If this is an option for your business, ask potential suppliers about switching to a time-of-use tariff to see if your business can make the most of off-peak deals.
3. Shop for agents
Suppliers employ ‘agents’ responsible for reading your meter, collecting data, installing and maintaining your meter and aggregating your data. Although suppliers will appoint agents on your behalf, there’s no reason you can’t appoint your own instead.
Shop around for supplier agents (external link): look for those that are half-hourly qualified, marked as HHMOA, HHDC and HHDA to see if you can find cheaper prices.
However, you should check the contract terms, for example the length of contract, to see it matches with that of your energy supplier.
4. Check your Maximum Import Capacity (MIC)
For businesses with a current transformer (CT) meter only.
In Great Britain, electricity suppliers and generators trade with each other to meet the needs of consumers. For each half-hour period they compare how much energy suppliers have bought, how much consumers have used, and then calculate what charges a supplier must pay to make up the difference.
This process is called ‘settlement’.
At present, before the introduction of Market-Wide Half Hourly Settlement, working out how much electricity consumers use every half-hour replies on estimates. This is because most customers do not have meters that can record their half-hourly consumption. However, suppliers are required by their licence to take all reasonable steps to install an advanced meter at the premises of customers in profile classes 5-8. These meters can record half hourly consumption.
Balancing and Settlement Code (BSC) Modifications P272 and P322 require suppliers to use their profile class 5-8 customers’ half hourly consumption in ‘settlement’. This means they need to record their customers electricity use every half hour.
BSC Modification P272 requires that businesses in profile classes 5-8 must be ‘settled’ using their actual half-hourly consumption data instead of estimates. This took effect on 1 April 2017.
BSC Modification P322 helped businesses transition onto half-hourly ‘settlement’. Under it, suppliers must make sure that all businesses who start or renew a contract are half-hourly ‘settled’. They must do this within 45 days of acquiring customers or renewing their contract. They’ve been required to do this from 5 November 2015.
