Personally, I would wire this up differently from a traditional lighting

MCB on the consumer unit. This reduces the effect of faults in the garden
circuit on the rest of the system.

Yup. For convenience, it would be easiest to use a timer which fits the
switch box, and use that to switch a relay. A suitable 20 amp one can be
bought from the likes of Maplin for under a tenner. The circuit the relay
switches can therefore be independant, or perhaps a fused spur off a ring
main - or have its own RCD etc.

Thanks Christian and Dave.

OK - my last (maybe) question(s). I would quite like
to use the switch I found at toolstation:
http://www.toolstation.com/search.html?searchstr=16578
but that's the one that has a max load of 400W and
having checked the specs on the greenbrook website
it's also not compatible with CFLs.

Will using this switch to control a relay which in turn
controls my lighting circuit mean that I can then use the
CFLs, as they are not directly controlled by the time
switch?

If so, then
(a) can I run the switch == relay circuit and the
relay-controlled lighting circuit from the same
6A MCB/RCB0 in the CU?
(b) can anyone recommend a suitable relay
(with a web link if possible)
