Back to the subject. !
Can you see any manholes with BT marked on them nearby ?.

I've just been to the place again (I haven't moved in yet) and I've found where it goes in. I can't believe I didn't see this before but I wasn't looking for it the first time I viewed the place:

The bad news is that on the other side of this wall is the back of the washing machine in the kitchen. There also isn't a double socket down there, not that I'd want my router behind the washing machine anyway.

What are my options for the FTTP install, does it have to be installed where this box is? The existing phone socket is on the other side of the building so I have no idea how the cable gets to there.

You can get microUSB connectors to solder onto the end of things cheap enough on eBay.

I got some of these

to convert one of these to power a Raspberry Pi 3B+ from my EdgerouterX-SFP

Been running just fine now for just shy of three years.

Or keep the soldering iron in the toolbox and get one of these for under a tenner. Isolated too:

That is an external NTE, if the current occupants have ADSL/FTTC it will have been bypassed and a regular NTE fitted inside.

Typically with a ducted feed at the top of the capping the existing entry cover, or in this case the external NTE, are replaced with a CSP. The fibre from the CSP can be run along an external wall before entering the premises, the maximum length from the CSP to the ONT inside is 30m.

I've just had FTTP installed and they run it round half way round the outside of the house from where existing came and brought it out by the master socket - where the copper enters is downstairs lav, just behind all the plumbing (which is boxed in with plasterboard) then goes across the hall somehow and enters cupboard under the stairs - the fttp just comes in the outside wall in same cupboard
