Very complicated plumbing job today, re routing 15mm copper pipe

You've added around 15m effective length to the pipe. I hope you
allowed for that when making the flow calculations.

You are assuming they were all in one pipe ;-)

That was how I read it, although, on reflection, it could have been
two or more.

They were on 5 pipes, 2 of which will be boxed in and 2 of which are under a
floor.
