SGN Natural Gas – NDM Meter Reading Procedures
[Public Draft]
4 Definitions
5
4.1.1
‘Gas Supplier’ means the current gas supplier registered on the SGN Natural Gas Asset Register at a Supply Meter Point (‘SMP’).
4.1.2
‘Meter Inspection’ means an inspection of a meter carried out by a Gas Supplier as per gas supplier’s licence condition 2.25.3
4.1.3
‘Registered User’ means the registered gas supplier at a SMP who has acceded to the SGN Natural Gas Distribution Network Code and is bound by its terms and conditions.
Procedures 5.1
Submitting NDM Meter Reads And Meter Inspection Data
5.1.1
As per section M3.10 of the SGN Natural Gas Distribution Network Code a GS is required to submit to SGN Natural Gas all valid NDM meter readings obtained by the GS.
5.1.2
GS should complete the ‘Provision of Meter Reads Template with meter inspections’ spreadsheet with all valid NDM meter readings obtained for a given month (See Appendix A).
5.1.3
GS should include in the template all valid NDM Meter readings including those readings submitted as part of the SMP Confirmation process and NDM meter readings taken for EUC3 classified SMPs in the month. Note: For clarity the provision of information to SGN Natural Gas by the GS as set out in this procedure does not remove the GS obligations under the SGN Natural Gas Distribution Network Code with regards the provision of meter readings as part of the SMP Confirmation Process or the monthly meter readings for EUC3 classified SMPs (See clauses M3.17 and M3.13 of the SGN Natural Gas Distribution Network Code).
5.1.4
GS should populate the ’Meter Read Import From Supplier’ template as follows: •
Populate column A with ‘SMP Registration Number’ i.e. SMP Reference Number e.g. 123456
•
Populate column B with ‘Meter Serial Number’ e.g. S12345678
•
Populate column C with ‘Postcode’ e.g. BT1 1AB
•
Populate column D with ‘Meter Reading’ e.g. 12345

o
“DB”, “P”, “Q” - Meter Readings received for prepayment meters recorded at the time of a top up by the customer

5.2.7
SGN Natural Gas will provide the GS with a file of rejected NDM meter reads and associated Meter Inspection notifications broken down by the issues as outlined for stage 1 and stage 2 of the process. The rejected meter reading will be issued to the GS on the ‘Rejected Records Template’ spreadsheet (See Appendix B).

SGN Natural Gas – NDM Meter Reading Procedures
[Public Draft]
Note: For clarity the timescales set out in this paragraph are based on a best endeavours basis and only meter reading files provided to SGN Natural Gas by the GS by the last business day of the previous month will be analysed for the purpose of producing any rejected meter reading data within these timescales. 5.2.9
For any rejected meter readings where a meter inspection has been conducted the meter inspection may also be deemed as invalid and rejected by SGN Natural Gas. Details of the meter reading and meter inspection rejection categories are set out in Appendix C of this procedure.
5.2.10 GS will review all rejected NDM meter readings and resubmit any amended readings in a subsequent month’s data files. Note: For clarity, although there are no set timescales for the return of information to SGN Natural Gas for meter readings submitted in any given month, the GS must ensure that the information has been validated and amended were appropriate before resubmission of a valid meter reading for a previously rejected record. 5.2.11 Any inaccuracies suspected in the AR following investigation by the GS should be submitted to SGN Natural Gas via the SGN Natural Gas Interface System 3. (See section 5.4 of the SMP Confirmation System User Manual for instructions on how to submit details of inaccuracies via the SGN Natural Gas Interface System.) 5.2.12 Any corrections accepted by SGN Natural Gas where previous Meter Inspection notifications had been advised and rejected as part of this process, SGN Natural Gas will reinstate the ‘Meter Inspection conducted’ flag on its system used for this purpose.
5.3 Rejected Records 5.3.1
The number of rejected records included in the file is the total number of records with issues identified post SGN Natural Gas investigation.
5.3.2
The rejected records file is split by category of issue identified as listed for stage 1 and stage 2 of the SGN Natural Gas process. It should be noted that multiple issues may be identified with a specific record therefore the record may be included in one or more categories within the same file.
5.3.3
Records identified with issues in stage 2 of the process will include notes on the outcome of investigation conducted by SGN Natural Gas where applicable to aid the GS with their review of the data.
5.3.4
The findings of the SGN Natural Gas investigations are based on the status of the SMP at the time the analysis is undertaken which is subject to change e.g. a SMP that was isolated could have subsequently been reconnected
3
7
As per Clause 4.11 where the GS becomes aware of potential inaccuracies in the AR they should notify SGN Natural Gas of such inaccuracies.

SGN Natural Gas – NDM Meter Reading Procedures
[Public Draft]
GS should review and remove any duplicated records from their files before submission to SGN Natural Gas. 5.4.3
Postcode Errors Where a Postcode Error is identified and SGN Natural Gas investigation determines that neither the GS nor SGN Natural Gas currently hold the correct Postcode the following process will apply:
5.4.4
•
GS should liaise with their customer to obtain the correct Postcode with the customer and advise SGN Natural Gas of the Postcode via the SGN Natural Gas Interface System; or alternatively
•
if verification of the record is not possible the Postcode obtained by SGN Natural Gas as part of validation checks from the Royal Mail address database should be used by SGN Natural Gas and the GS to update the record on both the AR and the GS system.
E6 Prefix on a Meter Serial Number Where an E6 prefix on a meter serial number is identified the following process will apply:
9
•
If the meter serial number submitted by the GS has an E6 prefix and the equivalent is not recorded on the SGN Natural Gas Asset Register the record will be rejected and the GS should remove the E6 prefix before re-submission to SGN Natural Gas.
•
If the meter serial number submitted by the GS has an E6 prefix and the equivalent is recorded on the SGN Natural Gas Asset Register the record will be accepted for validation by SGN Natural Gas. SGN Natural Gas will then update the record on the AR to remove the E6 prefix and notify the GS via daily reports issued. Upon receipt of this notification via the daily reports the GS should also remove the E6 prefix from their records.
