Come on boys (and girls) in blue - isn't it time you realised you're in the same universe as the rest of the world and played accordingly?
As I recall they tried to, at least for a while, in the late 1980s. Can't have been much of a success (for them) because they changed back pdq.
The RN at the time remained QFE based, as they are today. I can see some point in this. Not a lot of terain to miss at sea (one of the reasons I actually like flying over it, even single engined
)
