I'm currently preparing to have my current domestic heating/plumbing
system replaced and will be using a combi boiler. I have almost
everything sorted out, but I can't find any info on what to do with
the relief valve pipework.

It must be copper and terminated outside at low level, typically a few
inches from ground level. There must be an elbow on the end of the
pipe to
direct any discharge against the wall. The pipe does not have to be
sleeved
running through a wall.

Thanks for the info. I assume that if there is no route to ground
level (as is my case) I can terminate the pipe into a roof gully?

Some do not.
