Plumber says this is difficult if the old pipe isn't circular enough to
attach the connector he has in mind.

Isn't there a connector which could be soldered to the lead pipe side,
somewhat irrespective of its exact profile?

[My preference is to polypipe all the way to the water meter in the
pavement, but that involves digging up (and reinstating) rather a lot of
concrete path. As well as presumably getting the Water Company
involved.]

Â*Â* declared it so low it probably wasn't a lead pipe anyway. Ho Hum.

No big deal to connect lead to copper using solder. For a decent plumber.

The consensus is that this is now banned for potable water.

And copper to plastic then gets you into not needing a decent plumber.

One thing I've learnt in this thread is that there's probably no such
thing as a lead-polypipe connector. You have to go via copper.

I've read the thread as pointing to either copper soldered to lead or a
lead-lock; and you can use lead-locks to plastic pipe (with insert where
appropriate).
