Found it

Woke up and spent the morning attacking the dining room. Managed to find the aerial wire in the end. Tucked between the bottom of the plasterboard and the top of the skirting board. Had enough slack to cut the wire back and attach another lead so it could be run inside the wall for the TV on the wall higher up.

Electrical socket was also installed and the holes filled back in and plastered before going off to see Danny for a BBQ.

Went to the off licence down the road to get some beers in before getting the bus over to Danny's from Prices street.

Had a great night catching up with a windy and not so warm BBQ before getting a taxi back home in the early morning.
