MID approval
Under the Electricity Act 1989 all
electricity meters used for billing
purposes must be approved.
The approval for these meters is
obtained by conforming to the
European Measuring Instruments
Directive (MID) 2004/22/EC
(replacing OFGEM approval).This
directive covers a number of different
Instruments that are used to measure
products or services for reselling.
Therefore not only does it apply to
Electrical Meters but you may see
MID approval on a range of items
such as the charge meter in a taxi,
beer and wine glasses (the volume
measurement line) in a Public House
or on the petrol pumps when you are
filling up your vehicle.
Who should be using MID
certified meters?
By Law, anyone who is taking a meter
reading that is then used for billing
purposes and for which they
subsequently receive a payment from
the user for the electricity consumed.
Some typical examples:
l
A Retail shopping centre owner
wants to measure the individual
consumption of all the store
owners in his shopping mall and
send them separate invoices for
the electricity that each has used
to run their business.
l
A Landlord who wants to measure
the electricity used by tenants
renting apartments in his building
and then send them a bill for the
electricity they have used.
l
A caravan/mobile home Leisure
Park wants to measure the
consumption of its customers and
charge them an exact amount for
the electricity used at the end of
their rental period.
All of these examples must have the
electricity consumption reading taken
from a certified MID approved meter.
The MID certification validates that
the meter is manufactured using
quality components, assures the
meter is accurate for electricity billing
purposes and that it maintains this
accuracy over time for consistent
readings.
Standard Meters - Non
MID approved
If a meter is being used purely for a
“check meter reading” and not being
used to resell or charge for electricity
consumed, then a standard meter that
is reasonably accurate may be used to
measure energy used at that point in
time. For example, a check meter
reading is required to meet L2
Building Regulations and Chartered
Institution of Building Services
Engineers TM39 guide to Building
Energy Metering. The reading taken is
used as a ‘check point’ to help reduce
energy consumption.
