I've had a look at TLC and the Wylex range seem to be the only ones
that can be used with either fuses or MCBS. The other products do not
mention fuses. The price seems reasonable enough too. There is also a

Hager also do HRC fuse carriers for their consumer units. They also fit
Contactum and MK enclosures.

(and they do come with a fuse fitted (still not found a use for the
spare I ordered! ;-))

plastic version a little bit cheaper. Is there an advantage to using
the metal or the plastic version? I guess metal is stronger so takes a
few knocks but on the other hand, doesn't it pose a problem in that it
must be earthed?

Assuming your not TT[1], then either should be ok. Earthing the metal
ones is not difficult - they usually have the earth bus bar riveted to
the metal of the box anyway, so it is hard to avoid.

[1] With TT installs its better (IIRC a requirement) to use insulated
CUs since it lowers the possibility of a fault to earth occurring on the
up stream side of your RCD, where the earth fault loop impedance will
probably be too high to sink enough current to open the main cutout.
