The two things which need to "fit" are where the water feed enters the

probably easier to source than the former, but a whole new unit needs
both, of course.

Aren't they made to a standard? We had no problems replacing both our
toilets
more than 30 years after they were first installed.

Where the water goes into the cistern appears to vary quite a lot.
External pipework is a lot easier to adapt than ones coming out of the
wall.

IME most these days will expect the feed to enter from the underside of
the cistern...

If yours comes out of the wall somewhere in the back of the cistern that
may prove more tricky - depends on how high up it is.

(moving it down, is possible obviously, but slightly more work).

Hopefully the "close coupling" is fairly standard, but a feature of this
model is a crescent-shaped lip in the top of the pan just behind the
hinges, which will constrain the dimension of the bottom of the cistern.

In many cases you may be able to, but its not a safe assumption that you
can in all cases - offsets will vary as will the mating surfaces.

Rather than like this one where it's essentially a flat shelf:

And like that one, there's a significant gap between the hinges and the
cistern. Most modern designs are much closer. If this means the pan
itself is closer to the wall, it might not marry up with the soilpipe
properly if replacing the whole unit.

That's usually less of a problem since there are a wide variety of WC
connectors available that have slight offsets, or bends, or flexible or
hinged bits etc. You can normally find something that will get the two
to mate ok.

I'm going to need to go to B&Q with a measuring stick!

Have you tried here for information about a replacement?

My model isn't available, and a more modern one is £200 for just the two
bits of porcelain. That's when I reached for this newsgroup, earlier.

You are probably between a rock and a hard place. If you want a
compatible match you may have to be prepared to pay top money, or just
swap the pan as well.
