Fitting pipes in place before rads.

Put the valves on the rads and measure the gap between them... Why can't you work out where the pipes will be required and put them in the correct place?

This is what i intend to do, but there will be some play invovled putting the pipes in the rads after, this I'm sure will cause some movement where the pipe exits the wall, just trying to minimise any damage to the plaster.

If you just leave stubs coming out, and use a pair of 45 degree bends later on, you can connect to any reasonable offset.

However the better advice is to use packing to fit the radiators where they will go, get the piping right, and then remove the rads and as much piping as possible to let the plasterer have access.

Top idea!! If I pack with 15mm timber (10mm sand/cement 3mm pink, give or take) would this be stong enough to mount the rads to if I use the timber as just a spacer, i.e. drill through and put the rawplugs in the wall behind the timber? also what is the tidyest way of having the pipes exit the plaster on the wall, I'm thinking of using a 90 out of the wall as if I just use the bend in the microbore it would be a bitch for the plasterer I would imagine.

You don't need to *mount* the radiators on the wall, put some bricks under them to take the weight while you draw round where the pipes go. (Have a 2nd person hold them so they don't topple.)
