VM are changing the encryption (which in all likelyhood will require hardware changes at each headend), and are implementing other changes at the same time, which require hardware changes.
As such, it's not nearly as simple as you appear to think. Sky don't need to bother with area by area installs. I doubt they have any more than 1 head end that needed changes to hardware, so it's easy for them to do the whole country at once.

Sky can change the keys via an EMM. They have fundamentally changed the encryption system twice now requiring new cards.
Sky have two main hardware centres but there are also all the third parties who provide transponders as part of the Sky epg. The last update was tested for years before it was rolled out, and then the rollout took around 6 months.
Virgin are changing from three central headends, to a main and backup. They are going from a mish mash of hardware providers to a single provider. The new hardware is what is enabling them to use the new encryption.
