I've just installed an electric shower. The 6mm T&E cable runs from the

inside trunking or conduit where it runs through the airing cupboard, or
can I simply staple it to the back of the cupboard's door frame, using
cable clips like this: http://tinyurl.com/nllh2b2

Many thanks for any clarification..

In general, no, it does not need to be in trunking.

Doing so will mean the cable will get a slightly lower rating compared
to being in free air (clipped-direct method).

However, if you have a reason to suspect the cable will get clouted by
hard things in normal use of the cupboard, then it should be protected
(installation appropriate to the environment). It's not a hard and fast
rule, you will need to assess it.

Cables are normally surface mounted and clipped in airing cupboards, if
you want a "how's it normally done" baseline
