The most convenient place for me to keep my TV signal booster is under
the floor in the room where the aerial cable comes into the house.
Present arrangement involves this being plugged into a socket above the
floor, with the cable going through a hole in the boards in an alcove.
This was a quick fix on moving into the house, but is not ideal when a
visitor / child switches it off, ruining any radio or television
recordings which are taking place...
Is it legal / safe to place a socket under the floor, screwed to a joist
for example, to power such a device? Under my floor, there is enough
space to crawl around, so ventilation is not a problem - it's the ground
floor. Screwfix do a range of fairly rugged sockets, so this could
protect against it being knocked in the dark.
I have easy access to the area under the floor, so there's no problem
going down to replace / check the device if it fails - though I've never
actually had one of these things break down.
