Well, SWMBO will be so impressed, you'll need the other 25m for the next
one!

Ideally you should get at least 3 core SWA - and only use the armour as an
_additional_ earth (tie the earthing tag supplied with the glands at BOTH
ends otherwise you could end up with a potential difference (albeit small)
between the armour and the earth conductor). With 4 core, you'll have a
spare conductor which could be used (switched from the same circuit) for
lighting or something else.
Glands are unfeasibly cheap at http://www.screwfix.com/product.phtml?6877
?2.73 each.
