This won’t help those in the North region, unless they live (as many do) in houses with, say, thick stone walls.
LOL, the last place that I lived was originally built in 1604, in the shadow of our medieval castle and reusing the stone from it, Such recycling of old structures was common back then.
As you can imagine the walls in my last place were pretty substantial, 3 to 4 feet thick in a lot them, so a smart meter HAN would probably have very little chance.
PS. What remains of the medieval castle standing, which is quite a bit despite the dressed stone being reused all over that part of the town, is still a scheduled monument, and there is even a famous poem about it by Wordsworth.

PS. And now you know where I live, at least the town that I chose to live in.
I’ve also been a bit unclear whether the Coms Hub Pilot that a few of us have signed up to is primarily more about HAN or about WAN.
Reading it again it does talk briefly about 4G WAN. But it then goes on to talk mainly about HAN.
….. The trial will hopefully allow us to swap your standard smart meter comms hubs with a new one without needing to exchange/replace the entire smart metering system within your home.
In the future this capability will help us to exchange and replace existing comms hubs with newer dual band and 4g variants to overcome in-home challenges associated with poor or low signal.
I though that coms hub only swaps were fairly routine these days, see the OP of this thread, so there must be more than just that to the pilot.
I’ll get some clarification for you @Nukecad
Thanks @Emmanuelle_OVO
However I think that I’ve already found the answers I was looking for and it does appear that this TCSO trial is about WAN and not HAN.
It is also mainly about the Central and South Regions, but should also include some trials in the North Region too.
I have posted what I have found, with a link and quotes, on the TCSO trial page itself:
Hey @Nukecad
I’ve been advised it’s more about HAN but it’s about the process of transferring data across rather than the act of just changing the comms hub.

As explained in the link, Trust Centre Swap Out (which is a Zigbee term), is about swapping the Comms Hub without having to recommission all the HAN Devices. The Comms Hub is the ‘Coordinator’ and ‘Trust Centre’ of the HAN, which means that when it is replaced, it has to restart the HAN and securely restore the Zigbee network key to all the HAN Devices. This is done by the Service User (Supplier) sending an 8.12.1 SRV (Restore HAN Device Log) to the new Comms Hub, which restarts the HAN and provides credentials to the Comms Hub for secure restoration of the network key to all the orphaned HAN Devices.
