my first post to uk.d-.i-y. What can I say , thanks everyone. I am in fact NOT going to stay in the property ( long divorce story that I won't bore you with ).
Aerial socket seems to be a must. 2 doubles in each bedroom and 3 each in lounge and d/room. RCD protected circuit will be for the d/room ( patio doors ) and one marked "RCD" by back door in kitchen.
