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.

Many thanks! The offerings at the above URLs seem a lot cheaper than
others I was looking at.
