This, although you might need a set of manhole keys.Lift it and have a look what's under there??
GPO.
Yes I know BT originate from them.
Potentially, that's a dangerous question.Why did I click on this thread? What was I hoping to see?
Could that mean it may not be in use anymore and not on BT records? Overall it's likely some sort of telecoms?
I bet you are all over the re-routed Falcon Brook under Northcote Road Battersea then ?Can you hear gurgling from underneath it?
I might take a screenshot and ask on a Facebook group I'm in.
This is another one of my, ahem, interests.
If they weren't forthcoming in the call, then obviously obsolete if telecoms.
But proceed with care. Anyone upsetting trenched utilities faces a multi £k bill from their team coming round to make good. I've seen it happen.

Can't beat a bit of https://www.iec.ch/world-plugs and it's companion site https://www.plugsocketmuseum.nl/The Interweb is a strange old place - there is a website based in Israel called the "ultimate manhole covers site" - it includes an interactive map of the world showing the location of some manhole covers - unfortunately there are none in Brighton, but there is a manhole featured in Epsom and plenty in London - who'd have thought it ;-)
