What's the
best thing for glueing two pieces of UPVC together ?

Plastic drain pipe glue - the grey stuff often made by Terrain. You can
buy the solvent glue at a BM.

Window beading is tough and usually hammered into place.
You'll be very lucky if the solvent weld doesn't break.

I would try some more window fabricators. My installer
broke one of my beading pieces, and the local fabricator
made up a new piece in a few minutes whilst he waited.
