I'm being continually bombarded by letters and phone calls from both
my gas and electricity suppliers to install second generation smart
meters. I'm reluctant to get one for my electricity, as I envisage a
time when they may use it to throttle or even cut off the power for
short periods when it suits them. But I don't see how that could
happen with a smart gas meter; it could be dangerous if the supply
were cut and then restarted. Am I right, and would a smart gas meter
actually inconvenience me in any way (although I can't see any real
benefit either, as the existing meter is outdoors and gets read once a
year by the meter-maid, and once a year by me. I think having a smart
meter would obviate the need for one of those readings, but I
understand they have to check it annually anyway)?
Had this email from SSE recently:
As part of our customer care, we want you to be aware that your energy
meter will need to be replaced by the end of 2024. Instead of waiting
until then, take the opportunity today to upgrade to the new generation
of SMETS2 meters.
We’re currently offering a smart meter installation at no extra cost
from 17 February 2020.
I'll wait to 2025ish and see what happens then.
We were at Mums the other day when a meter reader turned up and we
gave him access to the meters.
He asked us if we knew about smart (electricity I'm assuming) meters
and left us a card.
He did confirm that the meter would be the latest spec but I'm not
sure what advantage one would be to her (at nearly 90), living on her

The gas pipe network stores something like 3 days' gas supply, so there's no mileage in varying tariff by time of day. With electricity there is, and I'm sure it'll go that way at some point. There are several downsides to electric smart meters.
I only have electricity, and a smart meter. I hear that smart meters
can be remotely cut off, but after researching mine this does not seem
to be possible. It would need a bulky switch to cut off the maximum
Thanks for the link, which didn't work. I navigated the site and got
as far as:
which states "integrated 100A switch" on the "more information" tab,
but the link to their brochure on the "resources" tab is 404 not
I found it by Googling for the pdf, which directed me to
So now I'm in fear and dread like everyone else of being cut off
through some software fault!
The brochure contains the following words about communication, which
others have queried on this thread:
Intimate Communications Hub Comprising HAN and WAN Technology GPRS WAN
with Internal Bi-Directional Antenna Supporting DLMS COSEM (Optional
Module to Support External Antenna Variant) Zigbee HAN 2.4 GHz
Supporting SEP V1.2 HAN and WAN Compliant with SSWG UK Extensions
Local Optical Port - IEC 62056-21 (physical)
It wouldn't be that difficult to do if the swich was spring-loaded and
didn't have to be turned on again remotely. But a *really* smart meter
would bide its time until you weren't drawing much current!
To be fair, both statements can be true. Some installations just have a
dual rate meter, but no actual load switching capability. Others have a
switched output that typically feeds a secondary CU with the night
storage heater load on it.
The switched arrangements have fallen from favour due to the lack of
flexibility - i.e. you can't do top up heating during peak rate so
easily of the circuit is "off" at the time etc.
