EZY and BA have quite different SOPs but the concept of aiming to be stable by 1000ft and it being mandatory to be stable at 500ft is now virtually an industry standard.
In the U.S. the trend is to mandatory stability at 1000 feet, not 500 feet as many carriers did it for years. If the approach is not stable at that point, or the captain feels that it will not be stable at 1000 feet, a go-around must be performed, according to the ops manual at many U.S. carriers. This and the recent FAA interest in QAR tapes certainly tightens the screws somewhat in the real world ATC environment.
