Can a Smart meter be installed flat (horizontally)?

Some suppliers in uk wee supporting detached comms hub.
You have an incoming fuse and meter squeezed into the bottom of an already cramped cabinet space by the presence of two (more modern ?) consumer units. I don't really see many suppliers seeing that as being anyone's problem but your own.Reaper said:
I would argue sufficient space has been provided as proved by the fact there is currently a meter there. If they want to replace it with a larger meter that does not fit that is their problem to solve. As Reed_Richards said I suspect they will eventually choose to fit a new non-smart meter. Something I would not be keen on as it prevents me using any of the better tariffs suited to my PV & battery installation.mmmmikey said:It will be interesting to see where this goes from here. I expect that the supplier has the right to insist that the home owner covers the cost of any work needed to make the meter sufficiently accessible to be replaced...
Meter sizes have varied over time. My digital 5 port meter was nearly half the height of the standard single phase analogue meter and that analogue meter smaller than the second old digital rts meter - as it replaced both it created a lot of space of my meter cabinet. Giving lots of space for EOn to fit new CU tail isolator switches (for free)
The new compact smets1 smart plus comms hub took back the space of 1 old meter and as only 4 port needed an external contactor - about half the width same height as meter section - so those isolator switches needed moving.
There isn't any real free space in your cabinet at all.
As above perhaps an external cabled comms hub adjacent to the meter - I've only seen one photo - for an install by Octopus few years back - right next to meter - but both squeezed below what looks like a cu style enclosure.

You could - if want to benefit from smart - ask if the comms hub itself could be mounted in any limited free space or even external to your cabinet.
That is if your supplier supports that type of installation.
And I dont know if even if possible under regs to have external - does anyone know if comms hub has to be on same meter backboard etc.

It might be their meter but it's your boxing in, and they could reasonaby argue that if changes are needed to the boxing in to provide space and/or access for meter replacement that's down to you to sort out. Lots of people box meters in with cupboards, but there must be regulations about the extent / permanence of that boxing in and ultimately it's those regulations and how they are applied that matters.I think (but I'm not 100% sure of this) you may also find that they would be quite within their legal rights, subject to any backbilling arrangements that may apply, to bill you based on a reasonable estimate for any under-charge that has happened as a result of the meter running backwards. It may seem unfair given that you didn't know and they only know because you told them but again it's the regulations that matter here and it's a risk you should be aware of. (Does anyone know how this works - i.e. what the regulations say rather than opinions on the rights and wrongs of it all?).To be clear, I agree with pretty much everything you've said. I'm just flagging up that if they play hard ball there is a very real risk that, however unfair it may seem, you'll end up having to do the work on the meter cupboard as well as getting a bill for any loss they've made due to the backwards running meter.0

Any wireless connection is prone to EMI in a way that a properly shielded wired connection is not; it is crazy.Reed0

The people who design these things know what they're doing.
Edited - apologies if you read my initial pre-edited post, the wording was sharper than I intended.0 -
Hi @Reaper bringing this discussion back into the context of your post, the significance of this is that smart meters have been designed in a way that allows the communication hub to be installed remotely without any wired connection to the electricity meter. Put it another way all the design is there for you to have a fully smart meter with just a compact electricity meter in place of your existing one so there is some light at the end of the tunnel. Hopefully your supplier will be a bit tardy in their response to give time for a technical solution to be found, and hopefully they won't bill you for the backwards running. 🤞1

BUT does anybody know:
1) Are long leads possible?
2) Can it be mounted above the cabinet, not on the backboard?
