I need to replace some 13 amp double sockets.

Is it 'best' to get double pole, or is the difference in cost (~50p per
socket) not worth it?

It doesn't make much difference, I might have a _very_ slight
preference for double pole on RCD protected circuits, and single
pole on non-RCD protected circuits. When you've picked the make
and style you want, I don't think you normally get the choice
though.
