Havells offers a comprehensive solution to metering and
measuring energy consumption in buildings. The key
for Havells is our understanding of regulations, future
requirements for metering and what it means to the installer.
The range of metering solutions includes both integrated and
retrofit with features such as ease of install, pre-configuration
(reducing risk of errors) and MID options making the
installers life easy when considering metering.
The requirements for Sub metering of electricity in non-domestic buildings mandated in Part
L2 of the building regulations for England and Wales have recently been mirrored by the newly
introduced Scottish building standards published in October 2015.
As an additional legal requirement, landlord billing of electricity in commercial buildings must be
from ‘approved meters’ only. It is a criminal offence to use a non approved meter for billing.
