In an older Aberdeen property, adding a socket usually means cutting a chase into solid masonry or plaster, dropping a cable, and making good. It is dusty and slow, but the wall will take it and there is nothing hidden inside it that you can ruin.
A modern house is the opposite in almost every respect. Most new houses in this part of Scotland are timber frame, though it is worth confirming what yours is before anyone assumes. Where it is, the internal walls are studs and plasterboard with a void behind, the external walls contain insulation and a membrane doing a specific job, and both party walls and some ceilings are fire barriers with a rating to maintain.
That changes the instinct completely. There is often a ready made route already in the house, which is why a good installation here can be less disruptive than in a granite villa rather than more. But it also means there are things behind the plasterboard you genuinely must not casually cut through, and a chase into an external wall is close to the worst option available.
In an old house you make a route. In a new house you find the one that is already there.
