of them (they may be cheaper elsewhere).

It also avoids any Part P problems as you aren't doing any new circuits.

I forgot its cheaper using X10 but more prone to interference YMMV.

Thanks for the suggestion. I looked at the X10 switches at the above
URL, and could not find any mention of wireless control. Perhaps I am
missing something.

If I go for some kind of wireless switching, I'd like something that
could replace the existing lounge switch, such that I could have a
second switch that could override the new lounge switch by wireless
means. Can anyone post a link to such a pair of devices?

You need three bits of X10.

One switch to replace the existing switch plate Part no: 10031 on the link
above
(note that this is a dimmer and doesn't work with fluorescents, LV
halogens.. use 10030 which is just a switch but may need a neutral wire
running)
There are other X10 modules that fit bayonet sockets and 13A sockets if you
look around).

One RF switch http://www.letsautomate.com/10185.cfm
an one RF receiver http://www.letsautomate.com/11024.cfm

The RF receiver is also a switch unit which can be operated by the RF switch
above.
