With the fast-approaching deadline of industry modification P434 that materially
changes the way electric unmetered supplies are settled, IMSERV, the meter data 
management experts, have recently agreed to support two energy suppliers with the
transition. British Gas and Brook Green have both awarded IMSERV contracts to support
the evolution to the new unmetered trading arrangements in line with the requirements
of P434, one of the key stepping stones of the Market Wide Half Hourly Settlement(
MHHS) programme.

 The news comes as the P434 compliance deadline approaches on 4th April 2024. P434
requires that all new Non-Half Hourly (NHH) unmetered electric services need to 
be settled on a Hour Hourly (HH) basis. Existing unmetered NHH services will then
be migrated over a 12-month period, requiring a change of measurement class. Suppliers
that are not compliant after the 4th April will not be able to take on any new NHH
unmetered contracts.

 IMSERV’s expertise in managing electricity settlement, change of measurement class
for meters, and the extensive experience in unmetered supplies via the Power Data
Associates team, now part of IMSERV, means that they are best placed to support 
Suppliers through the changes required under the P434 modification.IMSERV’s acquisition
of Power Data Associates in 2023 means that the business is now unique in its ability
to offer support across the new MHHS services – Advanced Data Services (ADS), Smart
Data Services (SDS) and Unmetered Supplies Data Services (UMSDS)
