The hot water flow could be made a bit better with some 28mm pipe for as
much of the run as is possible before connecting to the tap.

That's useful information - though not for this particular job. Reason
being the structural arrangement. It's currently fed from 22mm so I
would guess the 28mm would only be marginally better.

Also, is there room for a clamp on boss under the branch on the main waste
stack ?

As above. I'd have to tear down walls (or at least give them some
serious treatment with my SDS drill) to get to the stack. I don't
precisely know where the stack is in this flat, though I have a
suspicion it is probably at the back of the airing cupboard - with 2
large water tanks in front of it (and 5 control valves with pipe
running in different directions) so I'm not about to expose it.

The other issue is that being a flat there are other properties in the
building, and I'm cautious about inflicting damage in this
arrangement. Bringing down a load bearing wall in a single dwelling
might be an acceptable if unlikely risk, but relieving several people
of their home is not something that's on my to-do list

The clamp-on boss suggestion is good idea though!

Just can't understand how any plumber could get away with such an
installation! It would have been so easy to fix these problems at
build time. I'll bet the original site manager wasn't up to speed on
this development.
