I too would recommend 'not' lifting the skirting boards. Lay as
suggested and cover expansion gap with suitable moulding.

Unless you've opted for an expensive version of this 'modern' floor
covering you're unlikely to get a very long life out of it, especially
in a high use area such as you describe. You'll probably be faced with
replacement in a relatively short space of time.

I would consider the use of glued joints to help prolong the life of
your flooring.
