through the living room wall via a vent (this cable would be some sort
of SWA) then down the garden (buried say a foot down) to the greenhouse,
cable terminated in some sort of trailing socket.
Anyone have any experience of running power out? I do not wish to
go the full; dedicated CU with armoured cable terminated in glands route.

By using a socket outlet, you're creating a spur. If it's not fused,
the cable should really be rated at the same as the ring main for that
distance.
A buried cable should be deep enough to avoid the possibility of
damage including future changes to your garden layout. One foot down
is unlikely to achieve that. I would bury it at least two feet down.
The cable should be surrounded by sand and have a marker tape far
enough above it that it will provide a warning before the cable gets
damaged.
Greenhouses also get hot so your cable (and any other electrical
equipment) must be capable of withstanding that.
