I would have thought is better to have "essential" and
"non-essential" circuits in every house.
And you think the teenagers are going to remember which socket to plug
something in to? Or the average person, come to that.

You think anyone is going to convert their existing house to that - put
all your furniture in storage, move out, have all the walls bashed
around to have a second set of cabling installed, replaster, complete
redecoration, move back in.

Dream on.

You are a very ignorant person.
This has been done for years in hospitals because the emergency
generators are often not large enough to meet the full load.
Essential sockets are usually red.
In acute wards, there are no non-essential sockets.
Most essential equipment is permanently connected anyway.

In hospitals, the sockets with a protected supply are installed at build
time.

It would cost very little to put such sockets into new build housing,
but it wold take decades to penetrate the market to any noticeable
degree. To retrofit such sockets would mean, as has been suggested, a
complete rewire of any existing house.

Doing it later costs a fortune and severely disrupts the area being
worked on (Typically a ward or block) unless that area is being
refurbished anyway.

John.

Most wiring is in trunking so not that difficult.
