P272 - Important changes to your electricity metering and billing arrangements

Share this Article

Recently, Ofgem announced mandatory changes for electricity customers with Profile Class 05-
08 metering systems.

A large scale change program has upgraded meters within Profile Classes 05-08 to ‘advanced’

issuing a communication update in late February 2015 when we will have more information for
