RCD

This depends on how the flat is used - if it is to be rented out then since earlier this year there is a need to meet the current wiring regs before  it can be let out - almost always that will mean you need RCD protection on some, possibly all circuits depending how it is wired.

If however just you and family live in it, then you are free to take as much or as little risk as you like. Now  30 years ago an RCD was only required for things that supplied outdoor equipment, so there may be one RCD protected socket for a lawn mower  and not the rest, and not even that if you are upstairs.

Generally the regs now require all domestic sockets to be RCD protected with very few exceptions.


In a 30 year old (1990 or so) installation there may be other things to watch for, lamp holders deteriorate with heat, UV light attacks plastic, switches may get scratchy so I suspect there will be more to it, and just fitting an RCD may find it trips and will not stay on, as there are further problems to be fixed further down,

Equally it may be in 1st class condition, and no need to do much at all.

Edit.

I think John eats quite a lot, or only caviar and lobster or something, asr a good job may be a bit more than that.

Hopefully however the job will last many years, long after the food has left the building.
