Yorkshire and other soldered fittings *no*.

Too harsh, they (15mm fitting onto 1/2" pipe that is) will go with a bit of
effort and quite successfully. Most of my radiators are fitted like this
(1/2" installarion converted to 15mm then onto rad).

There used it be special soldered fittings but I doubt they sell them any
more.

Yes I bought some not long ago, you can still get them I believe. The 22mm
to 3/4" ones are easier to find (as you can't do without) but you can still
get the small ones, I believe.

Always use compression fittings to join imperial to metric.

Easier but not better (but that's not an imperial metric thing!)
