Two approaches are common in the UK. The first is all the meters in a common area near the incomer, and then 1 submain per flat to each, this is common for smaller buildings or converted where a larger building is split.

The other is to have a ‘building network’ (nice guidance and pics from UKPN here) where there is a main incomer, and splits to N fuses (one per flat) then there are unmetered lines that have to be protected to prevent electricity theft ,and each flat has its own fuse holder with a dummy fuse ('red link') and then a meter.

The official ENA document is here, but it is a bit short on pictures.

Meters need to be accessible to be read and must be extra space to allow other things that the supplier may perhaps need  to add to the board in future like a test meter, time switch or smart meter telemetry module.

In terms of access there is a preference for metering to be accessible from outside the building, so it can be read with no one staying in for the day.

example requirements for a meter box  from UKPN page 11 that is for a house, but flats with common corridors or balcony walkway access are often done the same way
