In the Euporean NO Hole Card game, ENHC, which is played by almost everybody else in the world outside the US the terms Early Surrender and Late Surrender does not really apply. To be precise you have Early Surrender against any card except the Ace and NO Surrender against the Ace. So these terms are purely for the US players.
As for the calculation for the house advantage I would use the Late Surrender number in this website as an approximation. To use the Early Surrender number would mean that the house advantage would turn negative which is not possible in the real world. For a more accurate look at this you can visit
http://www.wizardofodds.com which has the detail math for the diffirent cards and play.
The important point I am making is that this is only a theoretical figure and would only apply if you are playing perfect Basic Strategy. Your actual house advantage depends on how you actually play the game. I have seen players throw their money at the casino with horrendous play and the house advantage there must be in the double digits.
So once again don't be fooled by the universal perception that "BJ has the lowest house advantage of all the casino games".
