Personally, I would wire this up differently from a traditional lighting
circuit. I would use a DP switched immersion timer (or any suitable light
switch and relay) and have independent RCD protection, too, run from a 3A
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.
