Thanks all for your replies.

The taps are off the bath, so there is no problem with possible enamel
damage.

Kilrock?
I've not heard of that......Is it widely available?
Yes it is. I got mine in either Boots or Richard Dyas.
I apply it with an old toothbrush. Usually takes only a few minutes.

Most descallers are sulphamic acid (except those for use on enamel).
Cheapest way to buy it is probably a tub of Furnox DS-3 for descaling
heating systems. (Actually, it lists several other things you shouldn't
use it on, most of which I do without any problems.)
