I've an outdoor socket on the wall in my back garden, which is
switched with a 20Amp switch inside. I want to use this for
outdoor lights, and to that end, I have an extension-cable-inna-
waterproof-box from TLC: http://www.tlc-direct.co.uk/Products/LBOPB.html

I'll plug that into the outdoor socket and plug the lighting
transformers into the trailing socket in the box. Except rather
than having the box directly below the socket, I want it at the
other end of the garden away, so I need to replace the 1.7m
lead with a 15m one I can run round the walled edge of the garden.
Should I make up this lead in 1.5mm flex, or 1.5mm Hi-Tuf?

I would use 3 core SWA. I would wire this into the back of the existing
socket, not using a plug. At the far end I would install another waterproof
socket into which your waterproof multiway can plug in with its existing
cord.

Use 3 core instead of 2 core. Although you should earth the armour as well,
it is best not to rely on steel for earthing, but use a proper copper core.

Obviously, you must ensure that the entire circuit is protected by a 30mA
RCD.

Would it not depend on how the original waterproof socket was connected
though? If it was already a spur from an indoor ring for instance, then
adding another spur from that wouldn't be allowed.

That would indeed be a possibility. A 13A FCU might be an appropriate
replacement for the 20A DP switch if the existing circuit is a unfused spur
from a ring.

I would use 3 core SWA. [...+lots more helpful stuff, cut for length...]

So would I if I were looking at a permanent installation, but for a
number of reasons I want an installation that I can roll-up at the
end of summer. I have looked at Hi-Tuf, but reading past threads,
I gather this isn't flexible enough to be used for a temporary
arrangement (if a few months can be thought of as temporary) - am I
right in this? In this situation, is standard PVC flex suitable, or
should I go for an alternative such as rubber flex or something
else entirely?

I'd go for heavy duty rubber cable H07RN-F 3G1.5 or 3G2.5
