Seen these things in B&Q that are like an immersion heater (I presume)
that screw into the bottom of a regular CH towel rail.

Are they very good

yes

and where might I get one? (Can't seem to see them
for sale in B&Q, just on a display model)

They're usually laid out in long boxes near the radiators in B&Q. If
not visible try asking for the plumbing guy or try a different B&Q -
maybe you need the big 'Warehouse' style B&Q.

I've seen them in several B&Q, though thinking back, they were all
w'house B&Qs.

The rad can get quite warm or even hot with these, so check you don't
fit one over rated for your size of rad: Check the instructions in the
box and/or radiator leaflets lying around in B&Q.
