Then there is the question of what happens when the winds are easterly.

The sound doesn't blow that far (and the takeoffs will be across the
north sea).

But the approaches won't be.

Indeed. They'll be turning onto the runway from east of London.

Maybe. Approach tracks are generally longer than take-off tracks the
glide slope being much flatter.
