Square Enix has decided not to region lock the European PC version of Deus Ex: Human Revolution.

"We're aware of some discussion regarding the planned region-locking of boxed PC versions of Deus Ex: Human Revolution and, after careful review, we have decided not to implement this in the UK/Europe," wrote Square Enix mastering manager Jason Walker (via Rock Paper Shotgun).

This will be true of "anywhere in Europe", Walker went on to clarify.

Therefore, PC versions of Deus Ex: Human Revolution bought in the US will work in the UK/Europe and vice versa, Walker confirmed.
