I seem to remember that it’s acceptable to cut branches overhanging into
your garden.
Is this correct?

Think so. Remember you've got to offer the branches back to the owner as
well....

That's my understanding too, and it is better to talk to your neighbour
first and explain what you want to do etc....
Not that that's always possible!
