Well, thanks to all for the advice.
As an aside, I have some rented houses that have a 100mA RCD on the
whole of the CU. Must have been a common way to re-wire them when
they were done approximately 10 years ago. Should I now re-wire them
split load. I hear the arguements about falling down stairs but think
it more likely a tenant will put a nail through a wire or similar.

Hi,

If better protection is required, a faster 30mA RBCO on the ring main
and possibly cooker circuit may help, as they're more vulnerable to
stray nails and dodgy appliances.

Maybe others can comment on whether a 100mA RCD will normally trip
when a light bulb blows.

cheers,
Pete.
Not in my experience. In fact, the 100mA trips have never tripped
unless they 'should', ie when there has been the type of fault that an
RCD is designed for.
