One in seven of the population of Britain is medically classed as
"deaf", though obviously the amount of loss varies considerably. That
means that in my row of a dozen houses, at least one, and probably two
of them will have a deaf person living there.

I'm 1/2 deaf.

I think the term 'reasonable expectations' would apply to all
installations.

Indeed. I think it is unreasonable to install an unbalanced lighting system
that may have interference effects over a wide area, including your
neighbour's property, who may not be able to use their telephone or watch TV
and certainly are unable to go into your house to fix the circuit.


TBH I've found that the OSG's recommended two-way switching circuit is
easier to understand and dead easy to install when compared with the
older way of doing things. The switch nearest the lamp is wired in
almost the normal way (permanent live goes in a different hole), and you
run a three+E to the other switch(es).

It's all easy when you do it every day!
