My 25 year old MEM consumer fuse box is still in A1 condition and I've
only had two fuses blow during that peiod. However I do feel I ought
to update and fit some MCB's.

My MEM fuses screw onto the live buss bar and the other side of the
fuse takes the wire for the ring main or whatever.

Can I replace these fuses directly with a screw on MCB like say this
from ScrewFix...
MK 16A SP Type B MCB 6kA

...or do I have to replace the consumer box to one that just has a clip
on supporting rail with the supply main wire going in one side of the
MCB and the ring main wire into the output side.

I found some MCBs in FADS about a year ago that had bayonets on them and
simply plugged in in place of the old rewirable fuse holders. Cost about £15
each and available in a range of ratings. I had to modify the plastic cover
on the CU cos they stick out more than the old fuses, but easily done with a
small saw and knife. If you have trouble finding them let me know and I'll
take one out and get the manufactures name (if it's printed on there).
Much more convenient if a bulb blowing causes the fuse to go, as was
happening to me.
