Just thought I'd give you an update. Cheers the the info on the compression fittings (and yes, to us on this side of the pond they are "olives"). Annoyingly I could only get hold of 8 or 10mm compression joints, when the OD of the pipe is 9mm.
BUT... I bought a piece of steel pipe that fits snuggly over the current pipe for £4, bent it a shape to match the piece I cut out, and my uncle soldered it between the 2 halves. Fitted it other night, filled up system and all is good so far!!
If the solder holds I'll be a happy guy that just saved £93.20!!
