Fuse Energy - 4g smart meter question

I just got an email from Fuse offering to get me a new 4g smart meter. I'm quite happy to do it but I wonder if anyone has any experience with these. Specifically, I have an in-house unit that I keep a tight eye on and that I don't want to lose. Does anyone know if the 4g smart meters come with an in-house unit? Or if not, whether in-house units compatible with my current, lesser "smart" meter would also work with the newer one?
Many thanks!

    The HAN should still run on ZigBee, so in principle your current one could still work if Fuse pair it. Or they might give you a new one.
    But that's a big "if" and "might".
    You'll have to ask Fuse.

    You should probably get a new ihd to match the new meter, so make sure Fuse know you use yours and want one.

    I've still got an old lcd monochrome ihd, for my smets1.

    The 4g is the external to home comms to from your supplier, not the internal to home in-house display or gas meter if have one.

    2g which 2g/3g models have reverted to, for meters is due to go 2033

    Every home in the south / central area wiith a cellular smart meter will need a new 4g comms hub before then.

    Thank you both!
    I have contacted Fuze to ask about the IHD and they said they will send me on if I request it, once the meter is installed. So I shall do just that :)

    If switching to 4G also means immediately switching to Vodaphone (rather than at the end of O2's contract), it seems like an unnecessary risk for anyone relying on a working smart meter.

    My vodafone signal was actually better around town then my new 02 is - same brand of phone - different model though.
    Now that 4G have passed two - one minor, the other larger roll out trials - why fit a 2g/3g hub - knowing your going to have to come back before normal meter EOL to swap it for a 4G before 2033.

    "The first 4G Communications Hubs are being installed from December 2024 to February 2025, with mass roll-out from summer 2025."
    OR again from DCC site
    "Following a successful test, we’ll be rolling out 4G Communications Hubs as standard from summer 2025. Given that 2G/3G networks will be phased out by 2033, that gives us and our partners eight years to ensure connection continuity for around 24 million smart meters – a huge challenge, but one we are confident we will achieve.

    So the OPs supplier appears strangely on time for UK smart meter rollout planning if not in a trial area.

    Like the RTS roll out - that was a tiny fraction of total meters (Id say sub 5% of homes) - you probably really dont want to be waiting for the last minute for suppliers to mess up and delay the rollout to 29 m homes (or as it now turns out the 3-6 months after the last minute as people are still waiting now its a phased RTS shutdown.)

    And the DCC have already set up a specific group to plan the roll out of 4G into the North - currently the Arqiva LRR WAN locations.  Where many more anecdotally at least struggle with LRR comms.


    And I have seen mention of a joint 4G / Arqiva LRR WAN hybrid comms hub in some posts here too (not to be confused with dual band HAN - but not sure if these have been trialed or rolled out yet)

    My point is that if you have a working smart meter, switching to 4G carries a risk with no possible reward.

    That's true for now, yes.
    Smart meters seem to have a 10-year certified life, so the smart meter installers need to be staffed sufficiently to replace ~3M meters a year.
    If they start fitting 4G comms hubs this year, mid-2025, natural replacement (10% a year) means that there will still be 20-30% of meters with 2G comms by 2033 when the system starts to be switched off.

    You seem to be saying that they have an 8 year deadline and planning around a 10 year deadline.
