Thanks guys
I'm guessing that the following will be the answer.
Drillling a 25mm hole then installing 20mm plastic conduit followed by the 15mm copper pipe, sound right?

Hi Guys
I’m having a new extension built and was toying with the idea of fitting the radiator myself.
My question is, when taking the pipes through the cavity wall from the existing house is there a regulation or best practice on how this should be done.
