Same as above, Vodafone and it predecessors, don't have access networks so they don't have chambers on every corner everywhere. Just on their Core routes. Also in the case of C&W you missed off Energis, which like Norweb has the vast majority of its fibre overhead on its electricity pylon network.
Also everybody, except BT, already share their infrastructure. VM has fibre in Vodafone ducts, Level 3 ducts etc and vice- versa and have done for decades, they also lease dark fibres to each other on a commercial basis.
I didn't say they didn't but it's a lot less than you might think, and it's not BTs core network they would use if at all possible but fibre tails in their access ducts.
Many remote masts are connected by micro wave links and not cables.
Other examples I can give are Cumbria for example, there's mobile masts fed in remote parts of Cumbria where the fibre is run along the west coast mainline, then a dig of a couple km to the mast.
Fed completely independent of BT. You only would see a few VM chambers, if they weren't grown over.
Other instances similar instances are masts fed from core fibre run along canal towpaths.
There are loads of solutions to feed masts without having to go to BT, and if you had a wide knowledge of the sector you would know that without going to the default " it must be BT " stance.
You assume wrong, I've built and maintained VM's ( and forebears) networks for nigh on 20 years. I have intimate knowledge of its and other carriers fibre footprint.

Interesting post I'll grant you that. Could you explain what you mean by "fibre tails in BT's access ducts". Surely if they have BT fibre connected to the mobile masts then it'll be going back to a BT exchange? (as they don't share ducts). Do you mean that at the exchange it then switches to another provider's core network?
I take your points though, but it is just strange as round here is very built up, VM have a cable network and ducting everywhere. There's C&W ducting right up the A-Road. However, I can think of a Vodafone mast that is fed by two overhead fibre cables from BT. There's another mast that's off the main road and also fed by overhead BT fibre. I can't fathom why they aren't just using C&W for these masts.
On the industrial estate near VM's hubsite a new duct was dug 100m or so to the nearest MBNL mast so I'm assuming they've now abandoned BT's fibre at that site at least.
