Just has a letter from UK Power Networks stating their records show I have
one of these which is outdated and needs to be replaced urgently.

Be interested to know why this has suddenly become urgent. ;-)

However, mine was replaced by a single line fuse with neutral link some 40
odd years ago - before I bought this house.

But the point of this post is the diagram on the letter - to allow you to
identify your unit - shows an earth terminal as being part of their
obligatory supply. Last time I checked, this wasn't the case. Have the
regs changed? Can I demand they fit one FOC?
