Is this a looped supply?

[Beryl55]

I am thinking of having an electric car charge point installed and having looked in my meter box I am unsure if what I have is a looped supply. I think it is a single cable which is split, but could it be two cables in a single sheath?

Is there a date after which looped supplies were no longer allowed? My house was built in 2017.

Not a looped supply.
It's 2 conductors L and NE from one cable.

My house was built in 2017.

Pretty sure by 2017 it wasn't standard practice, even not being adopted where IMHO it made sense (rare put there are some*)

*A flat above a commericial premises, one supply originally, needed to be split onto own supply with separate MPAN for upstairs flat, got the circuits separated out onto separate boards, DNO all booked by someone else in the office, thought they would just loop a second cutout off the one next to it, afterall it had all been on one supply for god knows how many decades, but no, they actually dug the pavement up outside with all the associated fences and signs and disruption that entailed and brought another servcie cable into the building, queried it with them and was told looped supplies were not allowed to be installed any more. Think that was probably 2017ish. Sometimes I think there needs to be a bit of flexability in these things

2017 I doubt it's looped, but of course you could be the second and not the first.
As an example this is the second of a looped supply feeding 2 flats in what was a shop, the other meter box feeds the original flat over the shop.

Edit: and there are 3 car charging points on the building

Hi Beryl55, on the off-chance you are still on this forum and see this message - I'd be really keen to know if you found out for definite one way or the other whether this was a looped supply, as I have recently moved house and have the exact same 100A cut out, BS1361 Type IIb fuse and same cable layout (two cables from the bottom of the cut out that merge into one)!

Keen to install an EV charger; the 100A cut out and cable sizes are encouraging and point to it not being looped (seems to be more common for looped supplies to be 60A or 80A?), but the appearance of two cables coming out of the bottom of the cut out has still left me a little nervous.

On a related note, from what I've researched so far, it's possible for 100A looped supplies to still have EV chargers installed without unlooping if they have dynamic load balancing/a CT clamp. Does anyone have any experience of this? It's just the area on the front of my house is communal/jointly-owned and all tarmac, so maybe not so easy to dig up for unlooping!

Thanks in advance

I can see why they would want to phase out cables without proper overload protection inside buildings, especially in this era of EV chargers and suchlike.

As @SUNRAY said, you could be the second not the first, so in real terms only the DNO can tell you what you have.
