If your cooker hood is a chimney type then most people tend to mount
the connection unit (FCU) behind the chimney cowl so as not to see any
wires, the cowls are usually easy to remove to access the FCU if needs
be.

All of which seems to be the perfect solution. Yes, three sided bent
tin chimney. Not sure why I need a separate isolation switch, but rules
is rules.

Suppose I ran a short spur from the existing 13a socket, to a new
surface mounted 13a socket above the hood and behind the chimney? The
hood could still be isolated (by unplugging or switching off the new
socket), and would also be fused, within the plug. That way, just three
holes to drill through the existing tiles - two for screws, and one
larger one for the cable. The chimney just lifts off the hood.
