hey our house had rings on 15A rewirable fuses for 10 years or so (dad rewired the place but left the old CU in place with the same fuses it had before)
we never really had any trouble with this setup i think the kitchen fuse blew once every few years but it wasn't something you couldn't live with.

what breezer probably meant by what he said:
Why rewire a house and not replace the CU, and not even uprate the fuses from the old radials? Why introduce the potential pitfalls of rings without taking up one of the major advantages?
i think dad was following a diy book on wiring that didn't mention any options other than rings for socket cuircuits but didn't want to replace the CU (a 6 way bakalite wylex standard fitted with 2 5 amp rewirable fuses and 4 15 amp rewirable fuses) and either didn't know where to get higher rated fuse carriers or didn't know if they were suitable.
the CU was replaced later with a modern split load when we had an extention built a few years ago. The electrician fixed a few technical issues like lack of red sleeving on switched lives and a loft socket on the immersion cuircuit. but i don't think there were any really serious issues.
the old wiring was apparently really poor (i was too young at the time to remember anything of it) I think it was a mixture of lead and paper and VIR cable with switches that gave shocks and sparks. It pretty much had to be rewired.
