Also for those few odd airfields that have circuit heights of 800 ft or 1500 ft it is so much easier to fly QFE than have to do the maths, especially when you are trying to nail the turn onto final at 600 ft aal.
For Carlisle fly 1200 ft QNH, for Liverpool fly 1100 ft. Experienced pilots will judge their turn onto final visually rather than by reference to the altimeter. It's a useful skill to have for when the circuit has to be non-standard shaped for any reason.
