Retail Market Procedure NI 103 – Fieldwork
1.
Introduction
1.1
Scope
This document is the Retail Market Procedure for Fieldwork in Northern Ireland.
The Procedure applies to all non-domestic metered sites and to domestic metered sites where an MPRN has been allocated. Procedure includes fieldwork requested by
Suppliers or initiated by NIE T&D or customers or their authorised agents that may lead to readings or meter configuration or status changes.
Fieldwork includes:
 Special reads
 Meter and communication equipment problem investigations and meter accuracy tests
 Work impacting the configuration of a customer connection such as:
o Meter installation, exchange, re-programming and removal, including keypad meter re-configuration
o Meter replacement as a result of faults or re-certification activity
 Work impacting the status of a customer connection such as:
o De-energisations (other than temporary de-energisation e.g. for periods less than one day)
o Re-energisations
o Decommissioning and removal of supply
 Revenue Protection activities impacting the status or configuration of a customer connection
The procedure covers:
 Fieldwork requests from Suppliers
 Cancellation of fieldwork requests
 The reporting to Suppliers of fieldwork initiated by a customer or their authorised agent or by NIE T&D that impacts the metering configuration or status of a
customer connection (e.g. a change of MIC or a de-energisation)
 Fieldwork completion
 Requests by a Supplier for a keypad meter configuration change. Refer to MP NI 104 Readings Processing for transaction detail between the customer and the NIE
T&D
Excluded are:
 New connections, covered by MP NI 101 New Connections
 Scheduled reading, covered by MP NI 104 NHH Readings Processing
 Processing and distribution of readings resulting from Fieldwork, covered by NI MP 104, NHH Readings Processing
 Work performed on the network that does not impact the metering configuration or status of a customer connection
 Work performed on the customer site that does not impact the metering configuration or status of a customer connection (e.g. supply cabling or metering relocations)

 Customer contact details if these have not previously been provided or differ from those previously provided
 Change of tenancy or legal entity for HV and EHV customers
 Existence of Supply Agreement1
 Customer details if there is a change of tenancy or legal entity for HV and EHV customers
The Supplier may indicate a required date. This date is provided for information purposes only and actual dates will be
determined when the appointment is made.
Second Tier Suppliers must request keypad meter configuration changes by sending a fieldwork request message to NIE
T&D.
For Second Tier Supplier initiated requests (other than de-energisation and re-energisation for non-payment and forced
meter changes from credit to keypad for debt management ) for NHH Meter Points Suppliers should advise the customer
or their authorised agent to contact NIE T&D the day following the request submission in order to arrange a fieldwork
appointment or transact a keypad meter configuration change2. This is an interim requirement pending provision of an
appointment booking system open to all Suppliers.
NIE T&D
NIE T&D will validate the fieldwork request (see section 2.1.4) and will inform the Supplier of the acceptance or rejection
(with reasons) of the request.
N131 to Supplier
For Meter Points where connection is at HV or EHV then NIE T&D will ensure that there is a current Connection

Where there is not a Supply Agreement or there is no longer a Connection Agreement then NIE T&D is entitled the steps
outlined in MP NI 108 Meter Point Data and initiate de-energisation.
For HH Meter Points, NIE T&D will contact the customer or their authorised agent to finalise appointment details.
NIE T&D
For sites with HH or monthly metering NIE T&D will initiate the arrangement of an appointment with the customer or
their authorised agent to complete the request.
For de-energisation for non-payment and for re-energisation following de-energisation for non-payment an appointment is
not required.
For all other fieldwork requested by an STS, NIE T&D will arrange the appointment in response to a call from the
customer or their authorised agent. Appointments will be made in line with the Fieldwork Delivery Times outlined in the
Market Guide, MG NI 111.
If the customer or their authorised agent does not make an appointment or it is not possible to schedule the work for a date
acceptable to the customer or their authorised agent then the request may be cancelled.

2.1.3
Requestable Meter Configurations
Meter Configurations that are available for use in the non-domestic and domestic markets are described in ‘Permitted Meter Tariff’ worksheet in the “NIE Message
Specification – Data Codes” spreadsheet.
Unrestricted meter configurations may not be requested.
Meter Configurations are summarised in the ‘Meter Configurations’ worksheet in the “NIE Message Specification – Data Codes” spreadsheet.
2.1.4
Fieldwork Request Validation
A fieldwork request will be rejected if:
 The Supplier is not registered to the Meter Point. This validation is waived if the Supplier is an Old Supplier and is requesting a special read.
 The Fieldwork is of a type that cannot be requested by a Supplier (see section 2.1.2).
 A de-energisation is requested for a domestic Meter Point. Where a customer requires de-energisation then the customer should apply directly to NIE T&D. Refer
to MG NI 111 Customer Interfaces
 The request duplicates an existing request that is in progress
 Request required date is more than 40 days in the future
 A change of metering configuration is requested where a Change of Supplier registration request has been received and is pending completion 3. Where the
registration request is a first CoS from NIE Supply, fieldwork requested by NIE Supply will not be trapped by the validation.
 A metering configuration is requested that may not be requested by the Supplier (see section 2.1.3)
 A metering configuration is requested that is incompatible with the connection characteristics (e.g. MIC) of the Meter Point. In this case the Supplier may be
advised to request a configuration that meets both the Supplier tariff arrangements and NIE UoS tariff requirements.
 .
 A change of metering configuration is requested and there has been a previous change of metering configuration in the past twelve months. The Supplier may apply
for the change request to be accepted on the basis of a material change in the recorded pattern of demand or the type or hours of business undertaken, or a change of
tenancy.
 A change of metering configuration or an energisation is requested and the Supplier has not indicated that a Supply Agreement 4 exists with the customer. Where the
Supplier has an agency agreement then for MV and LV connected customers this must include a clause to cover customer acceptance of NIE T&D Connection
Conditions.
 For keypad metering a tariff configuration is requested that cannot be requested by the Supplier. Tariff configuration codes that are permitted for use will be agreed
between NIE T&D and each Supplier.

Revenue protection activities
Refer to Revenue Protection Code of Practice
Where fieldwork is chargeable to the Supplier on a transaction basis then:
 Charges will be levied as ‘ad-hoc’ items on a monthly basis through the UoS Bill
 Standard charges assume a single site visit
 Charges will be based on a published list of standard charges except in cases where special conditions occur in which cases charges will be agreed with the Supplier
in advance of work completion. Special conditions giving rise to non-standard charges are normally not known until the first visit has been made and include:
o HH communications are required that are not covered by the standard charges
o Special equipment is required
o Access cannot be obtained to the metering installation
o Repeated visits are required for reasons outside of NIE T&D control. These reasons include safety of the customers installation or property, inability to
obtain access, delays caused by third parties working at the customer site, requirements for special equipment
o Non standard metering configurations
 Charges will be levied:
o When the work is completed
o When NIE T&D attend the site but cannot complete the work for reasons outside of NIE T&D control
o When the customer or their authorised agent fails to keep an appointment arranged between NIE T&D and the customer or their authorised agent.

When, as a result of a meter or switching fault, a transaction is executed to switch from tele-switching to clock-switching5
(or vice-versa) a site visit may be arranged (e.g. to remove the tele-switch).
For keypad meter installations NIE T&D field staff will provide the new Premise Number Card to the customer.
For keypad meter removals only NIE T&D will provide a report of credit remaining on the meter to the Supplier. For
keypad meter replacements, credit will be transferred to the new meter
Report to Supplier
Whenever there is a change to, of or from a keypad meter configuration, NIE T&D will check that data in the key-pad
transaction system is consistent with that held by NIE T&D in the market systems and take corrective action where this is
not the case.
Please refer to MP NI 104 Readings Processing for details of keypad meter readings processing and keypad meter
configuration changes transacted by NIE T&D.
NIE T&D
Following completion, NIE T&D will provide a completion response to the Supplier when fieldwork has been requested
using message N031.
N131 to Supplier
N122 to Supplier
Where fieldwork is for the permanent removal of supply then the Supplier will be de-registered from the date that the
supply is removed.
Irrespective of how fieldwork is initiated, NIE T&D will inform Suppliers of all changes to meter configurations,
energisation status or UoS Tariff.
5
NIE T&D will use message N131 to advise Suppliers of all changes to an energisation status excepting new connection
energisations.
N131 to Supplier
Where an HH metering installation is completed or updated then message N331 is used. In cases where HH interval data
is collected this will be handled through procedure MP NI 105 HH Data Processing.
N331 to Supplier
Where NHH meter readings are collected, including those from a keypad meter, then messages N300S, N306, N307 or
N332 as appropriate to the request will be used. This is covered in more detail by MP NI 104, NHH Readings Processing.
N300S, N306, N307 or

If for any reason it is not possible to collect an actual reading on meter removal or de-energisation then readings will be
estimated in accordance with MP NI 104.
Where relevant, NIE T&D will update the UoS Tariff applicable to the Meter Point in accordance with any changes to the
metering configuration or other connection characteristics. This is covered in more detail in Market Guide MG NI 106
UoS Billing.
Wherever fieldwork is performed to install, exchange or remove a metering configuration, it will be an NIE T&D
responsibility to ensure that the following data is consistently maintained:
 Meter data used in meter reading
 The meter configuration in the keypad transaction service, including the tariff configuration requested by the Supplier
 The meter configuration used in UoS billing, registration and data aggregation for settlement
 The installed on-site metering
It is a supplier responsibility to ensure that meter configuration data is consistent with their customer billing arrangements
