Thanks, but as the plant has well overgrown the pergola should I cut it back
to well below what I want the final coverage to be to allow (estimate) for
next years growth or is it possible to cut it as it grows next year?

It is possible to prune out young growth, but don't prune anything
that has hardened up between winter and autumn. You can certainly
keep pinching/pruning out the tips (I did), where 'tip' may mean
a foot of growth or more. However, if it has overgrown its space,
you may want to hit it fairly hard.
