Leaving aside the merits of the argument for a moment, you will not believe what is on the Met Office's own website.
I quote...
"QNE is used to set the altimeter to the standard International Civil Aviation Organization atmosphere setting and assumes a sea-level pressure of 1013.2 hPa regardless of actual conditions. This setting is only used by aircraft cruising at high altitude and serves to ensure safe separation of aircraft.
QNH is used to set the altimeter to read the actual height above sea level in the local area, with the UK split into 20 different areas. All low-level aircraft use the QNH setting, including private aircraft, gliders, fast military jets and large commercial aircraft. The Met Office issues forecasts of all 20 QNH values every hour - coded FOQNH. Each forecast is for the lowest sea-level pressure value expected in the area during the hour".
