which also allows air to circulate freely? E.g. some sort of metal
sheet with very small perforations?

Would the metal sections that cover drainage channels as often seen in car parks etc fulfil the role?

You could drill your own holes, and cover them with some type of
expamet, but I suspect the carpet will stop circulation ...

I expect the carpet to stop most if not all circulation. Many carpets of
the cheap to middle quality seem to have the underside bonded with a
rubberised glue layer. Add underlay and there will be zero circulation.

Its possibly better to have a couple of vents either side of the space
to allow free air movement.

Yes, maybe vents or grills along the edge would work better. On
thinking about it there may be space at the bottom(s) of the units
either side to provide ventilation. I need to go and explore down
there.

Thanks all.

I think the gaps ore too wide really, there would need to be something
else between that and a carpet or whatever.

If you need something relatively small/thin just google for weep vents. Normally fitted in brickwork and in various designs. the long ones with multiple openings could be adapted and come in different colours.

Something like https://www.wickes.co.uk/Wickes-uPVC-Wall-Weep-Vent---10-x-65mm/p/224684

In that case could some lengths of cable tray do the job ?
