In fibre areas, the tiny inspection pot next to your property will have a wedge shaped lid. The old lids are rectangular.

I expect someone will know of other indicators.

Other indicator is the small cabinet opposite the chamber lid. VM (including its predecessors) have always used ducting from cabinet to the property so bringing fibre to the home is very straightforward.
