New master socket ... with wiring outside?

I'm due to have a new line installed, I'd like the master socket next to some plugs slightly above the skirting board - nothing unusual. However I don't want any internal wiring running down/along the inside walls from the junction box in the loft that connects to the drop wire. The room in question borders the driveway and I was thinking along the lines of simply running the new line down the exterior wall, then a simple hole through exterior wall, master socket in new room on other side of wall ... no internal wires visible(position would be almost at back of house and not visible/noticeable under normal circumstances).

So will the engineer do this or insist any extension has to be done internally, running from the loft?

I always prefer running externally to internally if at all practicable.

Does the dropwire come to the eaves above the wall you wish it come through ? That way the joint in the loft ca be bypassed.

Yes, the drop wire is on the same eaves as the exterior wall of the room, basic diagram here.

Last time I had an engineer install a new line it was for ISDN and he spent a whole day trying to produce neat internal wiring covering 4-5 metres - this seems simple by comparison.

Yep, that'll be a doddle, Cut at eaves, fit a sausage closure and run the lead in to where required, through the wall and into the back of the NTE.

Sorted.

Yep, the engineer did it no trouble - though he hadn't been properly informed by his system what type of job he had been assigned, so he was slightly confused when I initially asked him to do it.
