Prince Philip

Prince Philip is not Prince Consort.

Wikipedia tells us that his official title is:
His Royal Highness The Prince Philip, Duke of Edinburgh.

The same article tells us that:
the surname of male-line descendants of the Duke and the Queen who are not Royal Highness or Prince or Princess is Mountbatten-Windsor.
Another article clarifies that:
The official name of the British Royal Family or Royal House remains Windsor.

Prince Philip is also 468th in the line of succession to the British Throne in his own right.
